• Multi-item sustainable manufacturing model for cleaner production system under imprecise demand and random defective rate  
  by Saif Sami 
  Abstract: The present study revisits the multi-item economic production quantity model by considering that production process is not perfect with the planned backorder. The present study aims to make the production system as a cleaner production system by considering a reworking process for random defective items which is uniformly distributed. In addition to this, to make the production system cleaner, an investment is made to control the production process. Based on the reworking time, two different inventory models are proposed under the effect of uncertainty in demand. Impreciseness in demand is handled by applying fuzzy set theory. Centroid method is applied to defuzzified the objective function. The global optimal solution is derived by using a nonlinear optimisation technique. Numerical analysis with sensitive analysis is provided to illustrate the proposed model. From analysis it is observed that due to increase in investment, 98% reduction in waste management cost and 11% reduction in total cost is observed. Thus, investment in system improvement is helpful to achieve the task of clean production. The study also highlighted the advantage of outsourcing for a cleaner environment. In the end, sensitivity analyses are also carried out, and based on managerial insights are provided.

• Public Procurement Reforms in The United Arab Emirates  
  by Karem Aboelazm 
  Abstract: This study deals with several concepts: centralised public procurement, decentralised public procurement, e-public procurement, and sustainable public procurement. It also explains the advantages and disadvantages of centralised and decentralised public procurement, the benefits of e-procurement in the UAE at the central and decentralised level, and its advantages in combating corruption. The study also illustrates the sustainable public procurement framework in the UAE with its three environmental, social, and economic dimensions. The study relied on descriptive and analytical approaches. It reached several results, the most important of which is that the centralised system at the federal level contributes to reducing public spending. The decentralised system contributes to the speed of meeting the needs of local administrations. It also achieved several positive results from applying the centralised and decentralised e-procurement system, which reduces corruption, and public spending on public procurement simplifies procedures and saves time and effort. The study also found that sustainability in public procurement achieves several social, economic, and environmental benefits.

• The Role of Ethics in Public Sector Procurement Theoretical Study for Enlightenment Underpinnings of Ethics  
  by Karem Aboelazm 
  Abstract: This paper sought to present a concept of ethical behaviours in the field of public service in general and in public procurement in particular, as the issue of ethics is considered one that does not end up being addressed by literature or law. The study also attempted to identify ethical values in public procurement by reviewing the public office's most critical moral values. The descriptive approach was used to review the various definitions of ethics and values of public service. The analytical approach was also used to determine the causes and motives for the moral collapse in public procurement and the causes of deviation in this field. Some mechanisms have been found that can be used to overcome this problem, which is considered a significant challenge to public procurement systems in many countries.

• Payment Methods and Sustainable Inventory Management in Online Business: A Comparative Analysis  
  by Manoj Kumar Sharma, Shubham Bhushan, Pragati Bhardwaj 
  Abstract: In the dynamic world of online business, the choice of payment methods plays a crucial role in shaping how inventory is managed. Firstly, cash on delivery are examined for their immediate liquidity benefits, which help in quickly turning over inventory and managing cash flow efficiently. Secondly, advance payments are analysed for their ability to offer upfront capital, thus reducing the need for extensive inventory financing. Finally, credit payments (buy-now-pay-later and EMI options) are assessed for their potential to boost sales volume and consumer purchasing power. In this study employs a demand-sensitive pricing approach and explores investments in preservation technology. The decision-making process incorporates considerations of carbon emission policies and investment of preservation technology. The primary focus is on a comparative analysis of payment schemes in the context of online inventory management. Theoretical insights are validated through numerical examples and sensitivity analyses to derive practical managerial implications.

• Impact of Inventory Leanness on Financial Performance of Firms with Mediating Effect of Risk-Taking  
  by Farah Naz, Amna Bashir, Veera Salman, Anam Tariq 
  Abstract: This study investigates the impact of inventory leanness on the firms’ financial performance along with the mediating role of the risk-taking decision of those firms. This study analysed 244 Pakistani firms from 2010-2020 using Panel Regression Analysis. The statistical findings show that having optimized levels of inventory boosts the financial performance of firms. Moreover, the risk-taking decision of firms partially mediates this impact. Previous contradictory findings and fewer studies examining Pakistani firms in this regard mandate this study to be carried out. The study is limited by a few factors such as a specific country under study leading to a lack of generalisability. Additionally, the impact of inventory leanness on financial performance can be hindered due to uncontrollable or systematic risk factors, making room for future research.

• Focusing Supply Chain and Container Terminal Challenges from the Lens Of Indian Industries' Perspectives with Proposed Data Science Interlinked Artificial Intelligence Model  
  by Mohanbabu S, Vettriselvan R 
  Abstract: In any industry, logistics and supply chain management will play a major role in defining the strategy and competitive price. This paper aims to review existing literature on supply chain challenges and artificial intelligence involvement in logistics to overcome such challenges. The current study was carried out across various regions of India. Primary data was collected from 150 respondents who are involved in supply chain and port operations. Further, this paper focuses on examining the significance and difference of opinions among industry clusters with respect to functional roles and experience levels. Findings revealed that significance exists between various types of industries, and fuel prices influence operation costs. Finally, a data science-interlinked artificial intelligence neural network model (DSIAI) was constructed to overcome supply chain challenges and concludes that container port issues and operations also affect various industries when their efficiency decreases. The developed model provides useful insights into the logistics industry.

• Procurement Practices and Public Sector Procurement Performance in Ghana: the Moderating Role of Political Interference  
  by Lomatey Toku, Abdul Samed, Francis Andohbaidoo, Joshua Ofori-Amanfo 
  Abstract: Scholars and practitioners have shown keen interest in understanding how procurement practices influence public sector procurement performance. More importantly, there have been inconsistent results on this phenomenon. Political interference has been noted as a potential contributing factor, especially in developing nations such as Ghana, but has not been examined in prior empirical studies. Grounded in the agency theory, we explore two mechanisms that are key in influencing public sector procurement performance: 1) procurement practice; 2) political interference. Data from 308 procurement practitioners from state institutions in Ghana were obtained using questionnaires. Smart PLS version 4 was employed to analyse the data. The outcomes confirm a positive statistically significant relationship between procurement practice and public sector procurement performance. Additionally, political interference negatively moderates the relationship between procurement practice and public sector procurement performance. The contributions to theory and practice are discussed.

• Effectiveness of Utilising Social Media Marketing to Promote Handicrafts: a Comprehensive Analysis from Society Standpoint  
  by Jugal Kishor, Swati Sharma 
  Abstract: The rich tapestry has given rise to tangible objects, such as handicrafts, which are expressions of human ability, devotion, and creativity. Many experts in the field have stressed the many advantages of handmade items, praising their beneficial effects on both society and the environment. Focusing on the promotional aspect of Indian handicraft items using different social media platforms is the purpose of this research. Recognition, perception, and product value are the three metrics that the research uses to evaluate the efficacy of social media marketing campaigns targeting handmade items. This empirical study employed a questionnaire administered offline to gather data from 386 samples, which were then analysed using structural equation modelling. This study's results demonstrated that SMM for handmade goods significantly influenced the development of product perception, product recognition, and product value. In the social media setting, this research likewise showed that product value had a favourable and substantial effect on customers’ intentions to buy handmade items.

• Procure-To-Pay(P2P) Processes: an Empirical Exploration of Inefficiencies  
  by Jonas Ronellenfitsch, Jana-Rebecca Rehse, Fareed Zandkarimi, Christoph Bode 
  Abstract: In recent years, researchers have increasingly centred their attention on strategic and tactical procurement processes. In contrast to that, procure-to-pay (P2P) processes, which operationally ensure the availability of input resources, have rarely been studied. However, industry managers know that P2P processes can be a constant source of resource consumption and compliance risks. In this research, an exploratory analysis of real-world ERP data using process mining methods shows the nature of P2P inefficiencies as well as hints regarding their origin. Four requestor-related, four item-related, and four supplier-related factors resonating with a newly developed inefficiency indicator are structurally reviewed. This study contributes to the academic discussion on information systems in operations / process management in three ways: Methodically, by introducing and testing a new measure for process inefficiency; empirically, by applying the rather novel technique of process mining to a large-scale real-world dataset; and theoretically, by exploring the character of P2P inefficiency.

• Enhancing Sustainable Procurement: the Role of E-Procurement Implementation in Local Government Institutions of Ghana  
  by Abdul-Razak Imoro, Mustapha T. Seidu, Rebecca A. Boadi 
  Abstract: This study evaluates the extent of e-procurement implementation (EPI) within public procurement processes and examines its relationship with sustainable procurement performance (SPP) among local government organisations. Grounded in institutional theory (IT), this research adopts a descriptive quantitative approach, utilising a cross-sectional survey of 220 local government staff in the upper east region of Ghana. Data were analysed using descriptive statistics and multivariate regression analysis. Findings reveal that while procurement processes such as needs identification, specification of requirements and proposal evaluation are highly automated, others like contracting invoice verification and record-keeping remain predominantly manual. Additionally, EPI shows significant positive impacts on environmental impact, social responsibility, economic contribution, and ethical sourcing, with the strongest effect observed in economic contribution and the weakest in ethical sourcing. This study provides significant information for local government organisations on making informed decisions regarding EPI and highlights the importance of institutional dynamics in enhancing sustainable procurement practices aligned with broader societal goals.

• Main Benefits of Centralised Government Procurement: an AHP Application with Brazilian Experts  
  by Stéfane Nascimento Da Silva, Alexandre Nascimento De Almeida, Celso Vila Nova De Souza Júnior 
  Abstract: Public procurement has gained strategic importance within organisations, leading to a growth in centralization models in contracting. However, the effects of these models are still discussed and evaluated to a limited extent by administrations. The objective of this study is to hierarchize the benefits of centralizing public procurement, contributing to the design and implementation of this model in different contexts. Based on a literature review, the main benefits of centralised procurement were grouped into three thematic axes: 1) economy, 2) innovation, and 3) sustainability. Afterwards, a group of 22 experts ranked the benefits using the Analytic Hierarchy Process (AHP). The findings demonstrated a strong alignment between theoretical predictions and the insights provided by the consulted experts. Overall, the centralisation of procurement was identified as a key driver of enhanced governance, fostering an environment conducive to innovation. This, in turn, contributed to improved economic efficiency and sustainability outcomes.

• The Interrelationship between Economic Satisfaction, Trust, Commitment, and Non-Economic Satisfaction in Franchisee-Franchisor Relationships  
  by Margaret Theresé Constantaras, Pieter Gerhardus Mostert, Göran Svensson 
  Abstract: This study aimed to uncover the interrelationship between economic satisfaction, trust, commitment, and non-economic satisfaction by also considering the mediating role of trust and commitment between the satisfaction constructs in franchisee-franchisor relationships. A total of 415 South African franchisees completed a self-completion online questionnaire. The research and two rival models showed that economic satisfaction has an unequivocal influence on non-economic satisfaction and that trust and commitment mediate this effect. The findings contribute to our understanding of the interrelationships between the study constructs, specifically in franchise relationships, and offer insights to franchisors about how stronger relationships with franchisees beyond their contractual obligations could be fostered. The study contributes by validating, for the first time in a franchise context, the interrelationship linking economic satisfaction, non-economic satisfaction, trust, and commitment previously conducted in business studies and furthermore confirms the mediating role of trust and commitment on the relationship between economic and non-economic satisfaction.

• A Green Approach to Inventory Optimisation: Strategic Investments in Preservation and Carbon Regulation Compliance  
  by Manoj Kumar Sharma, Khushi ., Shalu Chaudhary, Nimit Jain, Mukesh Kumar 
  Abstract: As the urgency to combat global warming intensifies, reducing carbon emissions and mitigating waste from product deterioration have become critical priorities. This study presents an innovative and sustainable inventory model aimed at minimising waste through strategic investments in preservation and green technologies. By focusing on maximising total system profit, the model integrates a deterministic framework that accounts for price and advertisement-dependent demand, as well as time-variant holding costs, all within the constraints of a carbon cap-and-trade regulation policy. Especially, the model allows for shortages, which are fully backlogged, providing a realistic approach to inventory management. The study's primary objective is to identify the optimal value of the total profit function. We further validate the concavity of the objective function by applying both necessary and sufficient criteria, complemented by graphical representation. At last, we have completed numerical illustrations and sensitivity analysis to assess the model's effectiveness and practical applicability.

  by Ritu Pujara, Kunal Shukla, Dharmesh Katariya 
  Abstract: The proposed research deals with that the seller is offering eco-friendly cosmetics to the consumer. In order to catch the attention of new customers, the seller is selling items at a nearby exhibition and giving away free samples of his main product during the exhibition. The main product and free sample of main product are two inventories, with actual market demand are taken into account. Exhibition, distribution of free samples of the main item and green investment all have a direct effect on product demand. In order to maximise profit of seller with respect to optimum value of selling price, green investment, cycle time and order quantity, the problem is formulated as a mathematical model. The findings indicate the exhibition and distribution of free samples of main product significantly increased sales and total profit. Numerical example and sensitivity analysis validated the model and derived the outcome and finally concluded the article with future scope of study.

• VR and AR for optimisation of packaging sample processes in the food procurement process  
  by Nils Brehme, Nils Thomas Finger 
  Abstract: Despite increasing market challenges, procurement remains in most companies comparatively inefficient and does not leverage widely available technologies to the extent possible. Hence, this research seeks to support the digitalisation of procurement by investigating the potential of two selected technologies, namely Virtual (VR) and Augmented Reality (AR). This is done with a study on enhancing the packaging sample process in the particularly competitive food retail industry in Germany. In the context of increasing cost pressure, retailers are required to optimize and innovate procurement practices. By evaluating VR and AR as supplementary tools to traditional physical assessments, the study examines the technologies’ impact on efficiency and responsiveness. Interviews with industry experts confirm VR’s and AR's applicability across different product categories and emphasize considerable saving potentials for procurement. Considering related potentials and challenges, the technologies are best integrated as complementary solutions to established procurement methods, offering strategic advantages for sourcing operations.

• Optimising Inventory Model for Nonlinear Holding Cost and Nonlinear Price Dependent Split Demand with Advertising Frequency  
  by Vanjikkodi Thirumalaisamy 
  Abstract: This paper proposes an inventory model explicitly designed for perishable goods, integrating nonlinear time-dependent holding costs and diverse demand factors such as nonlinear selling prices, stock levels, and advertisement frequency. A partial backlogging approach for orders is incorporated to address shortages resulting from product deterioration. The model is meticulously formulated using partial differential equations and subsequently solved to derive the total profit function. Its primary aim is to optimize the retailer's total profit per unit of time by determining the optimal ordering quantity, optimal cycle time and the optimal selling price. Through graphical representations and numerical sensitivity analyses conducted using MATLAB, the paper demonstrates potential concavity within the model and emphasizes the importance of parameter analysis.

• Optimising Inventory Management with Preservation and Digital Labelling Technologies Under Green Technology and Advertisement-Sensitive Demand: a Deterministic Approach to Carbon Emission Policies  
  by Manoj Kumar Sharma, Manisha Prajapati 
  Abstract: In this paper, we developed an inventory model for non- instantaneous deteriorating items with a green technology and advertisement dependent demand. In this model we have consider two types of investment first, preservation technology investment to reduce the deterioration rate of food items and second, green technology investment to reduce the carbon emission which helps to contribute to sustainable development goals 2 and 13. In this study we considered the two policies for regulation of carbon emission i.e., carbon taxation policy and cap-and-trade policy. The shortages and partial backlogging are also allowed in this inventory model. Additionally, we incorporated digital labelling technologies, such as barcode technology, which reduce human error and improve data accuracy, resulting in lower holding costs. These investments enhance both energy and cost efficiency. Finally, we developed numerical examples and theoretical results to validate the model.

  Abstract: In the context of complex procurement processes, particularly in high-value industries such as military vessels acquisitions, relying on solid decision-making strategies is critical to selecting the most suitable suppliers. Addressing the problems of linguistic variables and uncertainty requires improved multi-criteria decision-making (MCDM) approaches. This paper provides a comparative analysis of the Fuzzy Technique for Order Preference by Similarity to Ideal Solution (FTOPSIS) and Fuzzy Indifference Target-based Attribute Ratio Analysis (FITARA) for group decision-making. Applying the Fuzzy Analytical Hierarchy Process (FAHP) for criteria weight aggregation, the study uncovers essential insights into the appropriate method for each military maritime vessel procurement scenario. Thus, it showcases significant differences in ranking outcomes, with FITARA displaying higher adaptability and the modified FTOPSIS maintaining stability under different settings and optimizing defence acquisitions.

• Management of Military Procurement  
  by Elias Saadeh, Moustapha El Hassan, Nabil Semaan, Jihad Daba 
  Abstract: Procurement management (PM) in the military requires rigorous planning, implementation, and monitoring. The procurement of products and services for military activities is subject to severe standards, including the federal acquisition regulation (FAR) in the USA and defence acquisition laws that assure security and safety. Given the strategic and complicated nature of decision-making in this industry, developing an adaptive project management technique is critical for ensuring optimal value, quality, and supplier support. This article conducts an in-depth investigation of supplier selection methods for public procurement in several nations, with an emphasis on high-value assets in the military and marine sectors. It emphasises the significance of reconciling operational objectives with regulatory limitations and provides a new multi-criteria decision making (MCDM) approach for assessing vendors. The methodology is demonstrated through a case study on vessel supplier selection, which includes engagement with several shipyards and stakeholders. The results show that this technique is effective at limiting risks, improving quality, and maintaining supplier support while providing an explicit and practical process for generating consistent and satisfying results.

• A Sustainable Fuzzy Economic Order Quantity Inventory Model with Linear Demand and Exponential Unit Profit Function in Circular Economy  
  by Anita Kumari Sahu, V. Ganesh, S.K. Inrajitsingha 
  Abstract: Circular economy is the one of the most targeted development in which remanufacturing, recycle and reuse the materials that creates job with minimised resource used. Application of circular economy is increasing day by day for economic growth and healthy business. Government encourages the use of circular economy instead of linear economy by providing subsidies through regulations and taxes. In this paper a fuzzy economic order quantity model in circular economy is presented. Since some parameters are uncertain in nature, they are considered as triangular fuzzy number. Defuzzification is done by using graded mean integration representation method (GMIR). In this paper, ordering quantity and circularity index level are decision variables. The concavity of the average profit function is shown theoretically. The optimality of the parameters is determined analytically. It is further endorsed by numerical example with an intension to validate the proposed model. The CE gives a remarkable gain in profit, which is the focus of any industry that is concerned about environmental conservation. The financial advantage of the company is given due weight age in this model. For this, sensitivity analysis is independently carried out by deploying circular economy in inventory modelling.
  Keywords: Circular Economy; Triangular fuzzy number; GMIR method.

• Keynesian Beauty Contest in Morocco's Public Procurement Reform  
  by Nizare RIANE 
  Abstract: This paper examines the recent reform of Morocco's public procurement market through the lens of Keynesian beauty contest theory. The reform introduces a mechanism akin to a guessing-the-average game, where bidders attempt to estimate a reference price, which in turn impacts bidding strategies. We utilize this setup to empirically test key hypotheses within auction theory, specifically the roles of common knowledge and bounded rationality. Our findings indicate potential manipulation risks under the current rules, suggesting that a shift to a median criterion could improve robustness and reduce the likelihood of manipulation. This work contributes to the broader understanding of strategic interactions in procurement and offers a foundation for future research on improving fairness and efficiency in public contract allocation.

• Untapped Potential in Albania's e-Procurement: Exploring the Consequences of Competition on Savings  
  by Edlira Martiri, Etion Kapedani, Teuta Xhindi 
  Abstract: This study focuses in Albania's e-procurement data from 2010 to 2023 which amounts to 5.33 Billion Euros awarded through 35,489 different contracts. To evaluate the effect that competition in public procurement has on savings the gathered data underwent segregation based on the number of offers received per tender. The metrics utilised are the amount of funds contracted; the number of tenders and finally relative savings. This research concludes that the largest amount of funds in Albania's public procurement has been awarded via procedures that attracted only one single bid, with low incurred savings. Simple linear regression is used to measure the effect that competition has on savings of public money, yielding a robust R-Square of 0.9587. This data model demonstrates an increase of 6.24% on savings when the number of bids is increased by one, concluding that Albania needs to embark on enhancing competition in public procurement.

• Optimal Resource Allocation in Military Hospitals Using Inverse Erlang-B Models  
  by Jihad Daba, Moustapha El Hassan, Elias Saadeh 
  Abstract: Effective resource allocation is vital for procurement management, optimising assets use to meet fluctuating demands while minimising operational bottlenecks. This paper advances resource allocation strategies by employing inverse Erlang-B models, specifically applied to military hospitals. Incomplete gamma and Marcum-Q functions are used in novel computational formulations to improve accuracy across various traffic intensities. In contrast, inverse functions offer tight constraints for calculating server requirements under high load. Assuming a 5% rejection rate and an average patient stay of 1.5 days, a case study models daily military hospital ward admissions as an autoregressive process (AR(1)), projecting an average demand of 86 hospital beds, with a minimum of 79 and a maximum of 91 beds per day. The findings demonstrate the effectiveness of inverse Erlang-B models in capacity planning, providing scalable solutions for optimising resource utilisation in healthcare and industrial sectors (Gil et al., 2013; Marinkovic and Stosic, 2023a).

• Investigating the Impact of Trade Credit Policies considering Deterioration, Quadratic Time-Stock Dependent Demand and Shortages with Partial-Logging  
  by Monika Naik, Shivkumar Sharma 
  Abstract: This study examines a warehouse model for deteriorating items with both owned and rented warehouses. It looks at how demand changes over time, stock levels, and allows for payment delays, enabling partial inventory fulfilment when there are shortages in the owned warehouse (OW). The model connects order delays to restocking times and analyses different scenarios based on payment delay options. The goal is to minimize inventory costs by determining the best restocking cycles, order sizes, and depletion points at the OW. The study includes algorithms to calculate these optimal values, helping decide whether renting a warehouse and using payment delays are worthwhile. With numerical illustration, it shows how this approach can optimise supply chain management by offering valuable managerial insights.

• Optimising Resource Allocation Through the Blocked Agent Retried Model in Military Manufacturing  
  by Jihad Daba, Moustapha El Hassan, Elias Saadeh 
  Abstract: Modern procurement management relies heavily on efficient resource allocation, which is crucial to maximising military, healthcare, and industrial performance. The practical utility of traditional queueing models is limited because they frequently overlook the dynamic retrial behaviours of blocked agents. To overcome these constraints, this paper presents the Extended Erlang-B (EEB) model, which incorporates a retrial dispatching mechanism. A new iterative approach was implemented to validate the EEB, and after 22 rounds, it converged to a steady-state traffic intensity of 15.8 Erlangs. Retrial techniques have been demonstrated to boost the utilisation of resources by 60% in practical situations. Dimensioning tables provide actionable insights for designing scalable systems for different retrial probabilities. The EEB model is pivotal for modern industrial and military applications, offering superior flexibility, accuracy, and robustness in resource allocation. Compared to traditional models, it effectively addresses dynamic operational demands across diverse domains, enhancing system performance and adaptability.

• Fuzzy Production Inventory Model for Deteriorating Items Defuzzified by Signed Distance Method  
  by S.K. Indrajitsingha, S.K. Sahu, P.K. Jena, Padmanava Samanta 
  Abstract: The research analyses a production inventory model of deteriorating items with shortages under partial backlogging in a crisp and fuzzy environment. Uncertainties play a vital role in developing a real-life inventory model. Since the system parameters such as demand, deterioration, holding cost, etc. are uncertain, so they are considered triangular fuzzy numbers. The model is developed both in a crisp and fuzzy approach. The signed distance method is used for defuzzification. The concavity test of the total profit function is shown graphically using the Mathematica 11.1 software. The objective of this model is to maximise the profit. A comparison of results in both cases is carried out to decide which method gives a more accurate outcome. The numerical example, managerial implications and sensitivity analysis are presented for the proposed model.

• An Integrated Inventory Model for Time-Varying Demand: Balancing Trade Credit, Pricing, and Sustainability Under Carbon Tax Policies  
  by Manoj Kumar Sharma, Sakshi Pant, Paras Jhaldiyal, Neha Rani 
  Abstract: This study proposes an integrated inventory model for perishable items with time-varying demand, where demand depends on dynamic pricing and trade credit incentives. The framework addresses delayed deterioration - spoilage initiating after a predefined latency period, typical in products like seasonal produce or pharmaceuticals. To reconcile profitability and sustainability, the model integrates preservation technology investments to curb post-latency decay and carbon tax mechanisms penalising waste-driven emissions. It balances the trade-off between extended credit terms (boosting demand but increasing opportunity costs) and preservation costs (reducing waste but raising expenses). A profit-maximising function is formulated, validated numerically, and analysed for parameter sensitivity. Results demonstrate that synchronising pricing, credit periods, and preservation investments optimises profitability while ensuring regulatory compliance. The study provides actionable insights for designing inventory systems that harmonise financial efficiency with environmental stewardship under carbon taxation.

• Deconstructing the 'Digital Arrest' Phenomenon in India: an Interpretive Structural Modelling (ISM) & MICMAC Approach to Unravel Drivers and Systemic Vulnerabilities  
  by ShivamKrishn Agrawal, Pooja Gupta, Vijay Kumar Jain 
  Abstract: Indias rapid digital transformation has triggered a surge in digital arrest scams, with victims losing 120.30 crore in early 2024 (PMF IAS, 2025). This study employs interpretive structural modelling (ISM) and MICMAC analysis to identify 14 systemic drivers including organised crime networks, weak legal frameworks, rapid digitalisation, and psychological manipulation through expert consultations with cybersecurity and media professionals. The ISM model reveals hierarchical interdependencies: foundational enablers (e.g., jurisdictional challenges, anonymity tools) facilitate mid-tier vulnerabilities like low digital literacy and manipulative tactics, culminating in fear-driven victimisation and social stigma. MICMAC analysis classifies variables into independent drivers (systemic corruption, inadequate enforcement) and dependent outcomes, highlighting multi-level intervention needs. Policy imperatives include modernising cyber laws, expanding digital literacy campaigns, fostering cross-border law enforcement collaboration, and strengthening public-private partnerships to dismantle transnational cybercrime networks. By addressing systemic vulnerabilities and societal resilience gaps, this research provides a structural roadmap for safeguarding India s evolving digital ecosystem.

• Impact of Environmental, Social and Governance Performance (ESGP) on Financial Performance of Indian Firms: the Moderating Role of Audit Committee Independence  
  by Anisha Mishra, Waleed M. Alahdal, Najib H. S. Farhan, Shayuti Mohamed Adnan 
  Abstract: This study explored the effect of environmental, social and governance (ESG) performance on the financial performance of Indian firms, with audit committee independence serving as a moderating variable. Utilizing quantitative methods and secondary data, the study analysed 91 Indian firms from 2018 to 2022. The research drew upon legitimacy, and agency theories, employing random and fixed effect panel data modelling for analysis. The findings indicate that ESG performance and its components have no impact on FP (measured by ROA), while ESG performance and individual performance of Environmental and Governance has a negative and significant impact on the financial performance (measured by Tobin’s Q), whereas the social performance has no impact on TQ. Moreover, the independent audit committee does not moderate the relationship between ESGP and its components and firm performance. Overall, this study is novel within the Indian context. It enhances the understanding that ESG performance has a negative or negligible impact on financial performance. This relationship is so strong that even an independent audit committee cannot moderate it.

• E-procurement Implementation: the Role of Organisational Culture and Organisational Learning  
  by Yaw Brenya Abunyewa, Ernest Kissi, Victor Acheamfour, Bernard K. Baiden, Alhassan Baako Braimah 
  Abstract: E-procurement is an innovative technology that is critical to boosting overall procurement performance. Therefore, it is important to understand the facets of its implementation. Hence, the study sought to evaluate the influence of organisational culture on the implementation of e-procurement and the potential role of organisational learning. The study applied the explanatory research design and a quantitative research approach to test the developed hypothesis with data collected from 98 Procurement Officers in public sector firms. The hypothesised paths were investigated using structural equation modelling. The study revealed that adhocracy culture significantly drives e-procurement implementation while hierarchy culture inhibits its implementation. Nevertheless, organisational learning nullified the inhibiting effect of hierarchy culture. This study provides an understanding of the intricacies associated with the E-procurement usage. The study argues that guidelines for the use of E-procurement must incorporate issues of organisational culture and learning. The study offers valuable insights concerning organisational culture, organisational learning and e-procurement implementation.

• A Proposed Prototype Application of Analytical Hierarchy Process (AHP) for Competent Bidder Selection  
  by Mangesh Kapote, Sunil Pimplikar, Abhishek Beede 
  Abstract: Bidder selection is critical in construction contracts. When multiple criteria and alternatives exist, pairwise comparisons become time-consuming and complex. Inconsistent decisions require re-evaluation, limiting analytical hierarchy process’s (AHP) practical use for large datasets. This study presents a prototype application for executing an AHP model on personal computers using user-friendly web technologies like ReactJS, React-Redux, and Tailwind CSS (Cascading Style Sheets). The application was tested on a road project in Maharashtra, India. To assess the AHP model, data from four bidders were expanded using Monte Carlo Simulation (MCS), generating 45 additional bidders. The dataset was divided into five groups, with the top bidder from each selected for final analysis. The prototype streamlines bidder selection, improves decision accuracy, and minimizes biases. It enables clients to conduct thorough evaluations, ensuring the most qualified bidder is chosen, thereby reducing project failure risks due to poor selection.

• Effect of learning and forgetting on an inventory model with imperfect manufacturing under inflation  
  by Surendra Vikram Singh Padiyar, Shiv Raj Singh, Vipin Kuraie, Naveen Bhagat, Umesh Kumari, Ummeferva Zaidi  
  Abstract: This paper considers a production inventory model for deteriorating items with an imperfect production process under the effect of learning and forgetting. Learning is the process of improving the performance of a system engaged in a repetitive task over time, while the process of forgetting involves rearranging or deleting systematic knowledge. The concept of learning and forgetting is best fitted in many real-life situations such as the automotive industry, stabilizer industry, etc. This paper assumes that production cost, inspection cost, deterioration cost and rework cost follow the learning effect while inventory setup cost follows the learning and forgetting effect. Inflation is also considered in this model. Production rate is taken as a constant, and shortage is not taken in this model. Finally, numerical examples along with sensitivity analysis are presented to illustrate the proposed inventory model.
  Keywords: imperfect production; inflation; deterioration; learning; forgetting.

• Optimizing Multi-Level Production Model with Diverse Production Rates under Inflationary Pressures and Shortage  
  by Sachin Kumar Verma  
  Abstract: The present research report focuses on an inventory model, specifically a production model, grounded in several astute assumptions that significantly enhance its effectiveness. By skilfully combining inventory and manufacturing management strategies within an inflationary economic context, the model achieves a greater level of credibility. This model assumes a multilevel production structure with varying production and demand rates, both of which are considered to be time-dependent exponential functions. Throughout the cycle, a constant deterioration rate is assumed. The inventory also experiences stock out situations following the production process. A numerical example illustrates a mathematical technique aimed at optimising the inventory cost function. Sensitivity analysis is conducted to further validate the model. The model's reliability is confirmed through verification. Mathematica-11 is utilised to determine the optimal solution.

• The Role of Complexity in the Decision to Centralise Public Procurement: a Case Study in the Brazilian Federal Government  
  by Waldemiro Francisco Sorte Junior 
  Abstract: This paper argues that complexities in some stages of the procurement process may have a greater influence on the decision to centralise a public bidding and proposes a classification of procurement complexity into four categories. A literature review was undertaken to summarise the existing research on Procurement Complexity and the advantages of Centralized Procurement. Moreover, this study empirically assesses the impact of complexity on a centralised bidding conducted by the Brazilian Government, through a case study involving a centralised procurement process for software development services. A deeper understanding of the interplay between procurement complexity and centralised procurement can provide insights into the decision to either centralise or decentralise an acquisition process and help promote a more efficient use of public funds, while reducing the risk of wasting time, financial resources, and human capital.

  by Yichen Sun, Vitrano Gaia, Mariani Costanza, Guido J.L. Micheli, Mancini Mauro 
  Abstract: Supplier interrelationships (SIs) in project-based contexts hold the potential to enhance project outcome, business performance, and supply chain efficiency yet remain underexplored and fragmented in current research. To capture existing knowledge, this study adopts a systematic literature review to analyse the state-of-the-art and identify key constructs and their interconnections. Through descriptive and thematic analysis, a conceptual framework is developed, outlining propositions and future research directions. Findings indicate that SI in project-based contexts is in its early stages of theoretical development, yet it offers substantial opportunities for enhancing outcomes. The reviewed studies span various project contexts, highlighting that SI varies across different settings. Current research focuses on four aspects: motivators, nature, outcomes, and influencing factors, while also addressing the SI evolution and dynamics. This study contributes to the theoretical understanding by bridging fragmented research through the proposed framework and provides practical insights for managing SIs across industries by identifying key constructs.

• A Green Inventory Model Leveraging Postponement Strategy with Advance Payment  
  by Sakthisree Periyasamy, Geetha Krithivasan 
  Abstract: In this study, we introduce an inventory framework for products subject to non-instantaneous degradation, partially backlogged shortages and an advance payment policy for retailers. The model integrates investment in green technology to mitigate emissions of carbon from transportation. In addition, postponement strategy is also employed to optimise efficiency, reduce inventory costs, and improve customer satisfaction by delaying certain processes until demand becomes more certain. A solution methodology is proposed to determine the optimal cycle length, time at which shortages begin, and the minimum total expenses for procuring and maintaining n-finished items in both postponement and independent systems.

• Role Stressor and Reduced Audit Quality Practices: an Exploration of the Mediating Role of Job Stress  
  by Mohd Nazli Mohd Nor, Roshaiza Binti Taha, Waleed M. Alahdal, Abdul Hafaz Ngah, Saiyidi Mat Roni, Salihin Abang 
  Abstract: The impact of role stressors, job stress, and reduced audit quality practices (RAQP) on the quality of financial auditing is investigated in this study. Role stressors are exemplified by role conflict, role ambiguity, and role overload. Data was obtained through a mail survey to Malaysian auditors and analysis was conducted based on a theoretical model of two-level job stress outcome employing Smart Partial least Square (PLS). The findings indicated that role overload and role conflict were found to be positively correlated with job stress, however the only factor found to be positively correlated with RAQP was role conflict. Additionally, there is a significant relationship between job stress and RAQP. Furthermore, the association between role conflict and RAQP is considerably strengthened by job stress. The findings also demonstrate the prominence role of RAQP in describing the audit quality issues. Although there are limitations to this study because it was difficult to get auditors to agree to participate, the results obtain are relevant to conform the findings from prior studies on the nexus between role stressors, job stress, and RAQP. This studys conclusions provide a convincing argument for auditors on the possibilities of job stress relating to the nature of work in this field.

• The Effect of Environmental, Social, and Governance on Corporate Debt: the Mediating Role of Information Asymmetry and Insights from the Natural Language Processing Approach  
  by Bui Thu Hien, Thu Anh Trinh, Nhung Ha Phuong Vu, Linh Thi Thuy Pham, Thanh Nhat Le, Cuong Xuan Trinh 
  Abstract: Using a sample of Vietnamese-listed firms over the period 20182022, this paper examines the effect of environmental, social, and governance (ESG) scores on the debt structure of Vietnamese-listed firms. A natural language processing framework is constructed to quantify firm-level ESG engagements using textual data from sustainability and annual reports. This research finds that companies involved with better ESG practices tend to have a debt structure that is more public (bond issuance) than private (bank loans). Information asymmetry is found to mediate the relationship between ESG scores and debt structure. While the social and governance pillars show significant associations with corporate debt restructuring, the environmental pillar does not. The paper highlights the important role of ESG scores in influencing firm debt structure, which contributes to investors and stakeholders understanding of sustainable financing in an emerging market.

• Harnessing Machine Learning for Enhanced Customer Relationship Management and Performance Optimisation in Retail Firms  
  by Kingsley Ibe Uche  
  Abstract: This study explores the potential of machine learning (ML) to enhance customer relationship management (CRM) and overall performance in retail firms, focusing on customer satisfaction, inventory management, and profitability. A quantitative analysis was conducted with data from 40 business analysts in UAE retail firms, using statistical techniques such as regression and correlation. Findings reveal that ML enables firms to identify consumer needs, predict purchase behaviours, and personalise services, boosting customer satisfaction and operational efficiency. Additionally, ML optimises inventory management and reduces non-essential tasks, leading to increased profitability. A majority (95%) of participants confirmed the importance of ML in improving CRM and business performance, including revenue and footfall. However, the study's focus on UAE limits its broader applicability, highlighting the need for further research across diverse regions. Retail leaders are encouraged to adopt ML technology to enhance customer understanding, streamline operations, and achieve sustained growth and competitiveness.

• Factors Influencing Real Estate Purchase Decision in Vietnam under Mediator and Moderator Factors  
  by Thi Thanh Chau Nguyen  
  Abstract: A supply chain networks with the effects of perishability, uncertainty and inflation, as well as time-dependent demand is studied. It is possible that due to various incidents during the production, some mistakes may occur in the process of manufacturing, and defective goods may be produced. Due to raised uncertainties of demand, the related parameters are considered to follow fuzziness. Since production is depending on the demand, therefore, the production rate is also affected by uncertainties. In order to include this effect, the production related parameter is also taken in form of triangular fuzzy number. Incorporating these factors, the model is formulated using graded mean representation to de-fuzzify the total cost function. To implement and understand the model in real life, it is very important to see it numerically, therefore sensitivity analysis for this model has been done with numerical example.

• Considering continuous review policy in a two-echelon inventory system using a reinforcement learning approach  
  by Adele Behzad, Mohammadali Pirayesh, Mohammad Ranjbar 
  Abstract: This research focuses on analysing a two-echelon inventory system comprising a central warehouse and several identical retailers. The system utilises a continuous review policy for replenishment across all facilities. The demand at the retailers follows an independent Poisson process, and the lead times are subject to stochastic variability without a pre-defined probability distribution. Additionally, the lead time for the warehouse, sourced from an external supplier, is assumed to remain constant. Unfulfilled demand is lost at the retailers, while it is backlogged at the warehouse. To optimise the ordering points and predetermined order sizes at all echelons, a reinforcement learning algorithm is developed. The proposed algorithm's effectiveness is evaluated through simulation and comparison with existing literature solutions. Moreover, the algorithm is implemented with both ordering points and order sizes as decision variables, demonstrating the efficacy of the Q-learning algorithm in this context.
  Keywords: multi-echelon inventory system; continuous review; lost sales; reinforcement learning.

• Investigating the impact of logistics practices on marketing performance of business enterprises: the mediating role of competitive strategy  
  by Arega Enbiale Setegn, Gurudutta Pradeep Japee, Aklilu Berhanie Desta, Girma Moges Admassie 
  Abstract: This study examines the mediated influence of competitive strategy in the relationship between logistical practices and the marketing performance of business enterprises. To choose sample respondents, purposive, and simple random sampling approaches were employed. The useable and effective questionnaires for this study included 330 responses. The survey findings were examined with SPSS version 26.0 software as well as AMOS 24, a structural equation modelling application. The study found that procurement, manufacturing support, and distribution practices had a positive impact on marketing performance. Furthermore, competitive strategy acts as a statistically significant mediator between procurement practices, manufacturing support, distribution practices, and marketing performance. Even if the findings are encouraged, their effects remain limited. To compete successfully in business and improve marketing performance, companies must ensure efficient and effective raw materials, and implement quality control procedures to ensure consistent product quality and optimise distribution channels to effectively reach their target customers.

• From inactive to proactive: examining social sustainability approaches and relational dynamics in procurement from a social capital perspective  
  by Jad El Bizri, Sven-Anders Stegare 
  Abstract: This study investigates how social sustainable procurement is characterised in terms of relational dynamics and its impact on social sustainability outcomes. Adopting qualitative research with a focus on the social capital lens, 21 semi-structured interviews with 30 respondents were conducted in the Swedish hospitality sector. Our findings point towards four distinct social sustainability approaches: inactive, reactive, active, and proactive. These approaches are influenced by the relational dynamics, encompassing dialogue, goal and cultural value congruence, and frequency of interaction. The study highlights the pivotal role of dialogue as a catalyst for transitioning from an inactive to a proactive approach. This research contributes to the development of a theoretical framework rooted in social capital theory, examining how relational dynamics influence the selection of social sustainability strategies. Furthermore, it provides valuable managerial insights, offering a social sustainability-procurement trajectory model that assists managers in assessing their strategic standing and guides them to specific improvements.

• Upstream decision to buy local products: how government role moderates the influence of product quality and capacity on intention to buy  
  by Widi Santuso, Mochammad Al Musadieq, Kadarisman Hidayat, Sunarti  
  Abstract: This research aims to test and analyse the effect of product quality and capacity on the intention and decision to buy local products with the government's role as a moderating variable. This study takes a quantitative approach by collecting data through questionnaires distributed directly to 90 companies and then analysing them using structural equation modelling (SEM). The research results showed that product quality and capacity significantly influenced the intention to buy local products and the decision to buy local products, and the intention to buy local products had a significant positive effect on the decision to buy local products. Meanwhile, the government's role significantly moderates the influence of product quality and capacity on the decision to buy local products. The research introduces a novel dimension by unveiling the significant moderating government role in shaping the impact of product quality and capacity on the decision to buy local products.

• The association between procurement process, e-procurement deployment and procurement performance in an emerging economy  
  by Lomatey Toku, Abdul Samed Muntaka, Francis Kofi Andoh-Baidoo 
  Abstract: Electronic procurement is critical in the reduction of procurement irregularities and inefficiencies in organisations and institutions in order to enhance value for money in the procurement process. This research is to examine the relationships between procurement process, e-procurement deployment, and procurement performance using the institutional theory as a lens. The projected model was empirically verified using primary data collected from 309 Ghanaian public organisations obligated to use the Public Procurement Act in their procurement activities. Analysis of statistics was performed using the partial least square based structural equation modelling method. The study outcomes validate that both procurement process and eprocurement deployment have a positive significant relationship with procurement performance. Further, whilst procurement process has a positive effect on e-procurement deployment, e-procurement deployment has a complementary partial mediation role between procurement process and procurement performance. For theoretical contribution, this research extends the institutional theory into the procurement literature. For practice, the findings provide insight for government practitioners and regulatory bodies to institute policies and protocols that encourage e-procurement deployments to enhance the activities of the procurement systems.

  by G. Bala Sendhil Kumar, C. Ganeshkumar, P. Victer Paul 
  Abstract: This paper analyses the impact of different factors on the adoption of e-procurement systems and detects the impact of the adoption of e-procurement on the operational efficiency and business performance of medium-scale industries. After a thorough investigation of the literature reviewed, the factors that facilitate the adoption of e-procurement were identified and the conceptual model was developed. The primary data was collected using a non-disguised and well-structured questionnaire from the executives in the production department of medium-scale industries that are using e-procurement. The sample size for this study is 432, the data collected is analysed using statistical packages of AMOS 20, and the conceptual model tested using structural equation modelling. This research study reveals that factors like organisational factors, technological factors, and supplier-related factors drive organisations to adopt e-procurement, and organisations using e-procurement enjoy better operational efficiency, which leads to an increase in overall business performance in the pandemic situation.

• Cost optimisation of single server retrial queue with standby server, extended vacation and delayed repair  
  by R. Poornima, K. Kirupa 
  Abstract: This paper analyses a steady-state queueing system with repeated attempts, coupled with a standby server during vacation periods. Clients arrive in batches according to a compound Poisson process. If the server is idle upon batch arrival, one client receives immediate service; the rest join the orbit. Otherwise, the entire batch joins the orbit. After each service completion, the server may take a vacation and may extend the vacation with a certain probability. During vacations of the main server, a standby server serves clients. The server is subject to breakdown at a random amount of time, and the repair starts after some delay. After repair, service resumes for interrupted clients. Using the supplementary variable method, the equilibrium condition of the system is derived, and the stochastic decomposition law is verified. The system's probabilities and performance metrics are obtained. The optimal standby rate is determined through cost analysis to minimise expenses for the proposed model.

• The antecedents of acceptance of halal food among non-Muslims in Ghana using the theory of planned behaviour and value-belief-norm theory  
  by Edward Markwei Martey 
  Abstract: This paper aims to examine the antecedents of acceptance of halal food among non-Muslims in Ghana using the extended theory of planned behaviour. The study employed a judgmental sampling method to collect primary responses from customers of halal food. Questionnaires were designed based on the constructs of TPB and VEN and were distributed to 463 respondents. The gathered data were analysed using partial least squares structural equation modelling to test the hypotheses developed through literature review. The results of the data analysis indicate that only trust in halal food moderated the relationship between personal value and acceptance of halal food. This research incorporated environmental beliefs, personal norms, personal values, and pro-environmental attitude as moderating variables on the constructs of TPB, with a specific focus on non-Muslims in Ghana.
