  • The effect of purchasing strategy on the economic production quantity model subject to random machine breakdown   Order a copy of this article
    by Farzad Dehghanian, Mehdi Deiranlou, Mohammadali Pirayesh 
    Abstract: In this article, we develop an economic production quantity (EPQ) model subject to process deterioration, machine breakdown and two types of repair, and study the influence of purchasing strategy on the system’s expected total cost, as an alternative option to holding safety stock. We assume that the manufacturer could purchase some quantities from an available supplier with fixed non-zero lead-time This paper looks for the optimal value of production lot size and purchasing lot size in order to minimize the expected total cost The model is developed under general machine breakdown and repairs time distributions The optimality of the model under exponential failure and exponential repair times are studied For the numerical example, we illustrate the outcome of the proposed model and perform a sensitivity analysis on parameters, which directly influence optimal decisions.

  • An empirical analysis of Lisbon hotel room rates determinants   Order a copy of this article
    by Conceicao Gomes, Luís Lima Santos, Cátia Malheiros 
    Abstract: This study investigates the impact of several characteristics and attributes of hotels on room rates in one of the most visited cities in Europe. The research allows to compare, in a transparent way, findings of previous studies and promotes added value using for the first time the Hedonic Price Model (HPM) in the hospitality industry in Lisbon, Portugal. Although hotel room price determinants have already been studied, in this study it was introduced physical variables and location variables all together, as well as it was added the variables relating to certain services offered. A significant impact on hotel prices by official stars and OTAs punctuation has been confirmed. In line with previous studies, an additional star and belonging to a chain allow the hotel to increase the price. In addition, other attributes, such as the distance of the hotel from the airport and the centre, have impact on hotel prices.

  • Corporate Social Responsibility Regulation and Its Adoption by Transnational Corporations in Indonesia: The Case of Chevron Indonesia   Order a copy of this article
    by Firman Hasan, Sri Oktavia 
    Abstract: Corporate Social Responsibility (CSR) has become an important concept within the global business community and actors. However, how CSR-related laws can be adopted and implemented remains unclear and it is still under-represented in research. This paper aims to answer the question as to how CSR regulations are adopted into business strategy and implemented by Transnational Corporations in Indonesia. This study uses a qualitative approach with the case study as its research strategy. The case study concerns Chevron Annual Reports and Corporate Responsibility Reports from 2006 to 2015. Interviews took place at Chevron’s Jakarta headquarter and Geothermal Salak in West Java, Indonesia. The interview scripts have been coded by applying the latent coding scheme, in which the themes and categories are inductively derived from the transcripts. The study found that the enactment of Law No 40/2007 on Limited Liability Company and other CSR-related policies have no significant impacts on Chevron Indonesia.

  • Two Inventory Models for Instant and Delayed Deteriorating Items with Price and Time Dependent Seasonal Demand   Order a copy of this article
    by Ashish Sharma, Amit Kumar Saraswat 
    Abstract: Deterioration is one of the basic assumptions of inventory models so the analysis of inventory models with deterioration will provide more realistic insights. In this paper we developed two inventory models with instant and delayed deterioration rate. Price and time dependent seasonal demand function is considered. In both the models we have an option that after some successive demand seasons whether we can continue with the same price or we can change the selling price. Analytical and numerical analysis provides important managerial insights. Numerical analysis shows that it better to reduce the price after some initial seasons with instant deterioration while with delayed deterioration selling price must be unchanged for as much as possible seasons.

    by Laura Panades 
    Abstract: The article shows how and to what extent Caribbean British Overseas Territories (BOTs) can integrate social award criteria in public procurement. In the past decade, BOTs have experienced economic distress, political misdemeanours and rising perceptions of corruption. Lacking public procurement experience, how can these small, remote and socially unequal territories make the most of UK-led reforms? This research comes at a time when their public procurement frameworks are in their infancy and looking for ideas. Experience in the EU, the UK and the Latin America and Caribbean region show successful results, primarily in small communities at the local level. The methodology used is desk-based research leading to a worldwide survey of successful practices and a legal and policy analysis on its application to Caribbean BOTs.

    by Prathamesh Potdar, Santosh Rane 
    Abstract: In a competitive business environment, API are preferring purchasing over manufacturing to achieve strategic business objectives. Therefore, project procurement management (PPM) processes are associated with many risks. Hence, API are looking for solutions to reduce the probability of risk involved in PPM process. A systematic literature survey (LS) has identified total 55 risks involved in the PPM process, out of which 14 critical risks were identified by using fuzzy logic with TOPSIS method and results were compared with PROMETHEE method. Blockchain-IoT integrated architecture has been developed to manage the critical risks involved in PPM process and nine strategies are suggested based on architecture. Blockchain-IoT integrated architecture can change PPM process with respect to data (real-time acquisition, storage, and accessibility), speed of response and quality of communications, data driven decision making, and transparent, auditable and trustworthy transactions. Integrated architecture improves the flow of knowledge throughout organization and reduces person dependent activities.

  • Payment Delay in Supply Chain Management: A Systematic Literature Review   Order a copy of this article
    by Salah Eddine Mohamed Hicham, Tarik Saikouk, Abdelaziz Berrado 
    Abstract: There is a general agreement in the literature that the payment delay (PD) is one of the strongest reasons for nowadays business failures. This paper studies PD in supply chain management (SCM) literature by providing a systematic literature review (SLR) of exclusively high ranked journals in the field of operation management. The authors identified five major issues in supply PD, namely inventory, cash flow, financial decision, supply chain (SC) coordination, and demand. They also discerned a growing trend in the literature related to analytical studies, which limits the generalisation of the findings, mostly due to the various assumptions used in the modelling process. The majority of these papers focused on the retail field because of its coordinated structure. This paper suggests that PD, as a coordination tool, can improve both the suppliers and retailers profit. The paper concludes by suggesting a conceptual framework that summarises how PD influences the issues addressed above. The authrs, pinpoint potential future areas such as simulation under dynamic scenarios, including multi-echelon partners in order to better gauge the impact of PD on SC performance.

  • Knowledge transfer in institutionalised supplier development initiatives: The moderating role of institutional factors   Order a copy of this article
    by Shem Sikombe, Maxwell Phiri 
    Abstract: Public procurement as a tool for socio-economic development has attracted considerable attention from supplier development researchers. Supplier development strengthens the management of suppliers and improves their capabilities through knowledge transfer. The article examines how institutionalised supplier development initiatives are associated with knowledge transfer and the moderating effect of institutional factors. The article applied multiple regression and moderation analyses on a sample of 171 contractors. Findings reveal that training and the 20% subcontracting policy are significantly associated with knowledge transfer, while the construction finance, preferential and reservation schemes are not. Regulatory compliance and government support moderate the relationship between institutionalised supplier development and knowledge transfer. Interactions indicate that low regulatory compliance is associated with high knowledge transfer, while government support is associated with high knowledge transfer at all levels. The article contributes to research by demonstrating the influence of regulatory compliance and government support on the implementation of institutionalised supplier development.

  • Inventory Model for Deteriorating Items with Ramp Type Demand under Permissible Delay in Payment   Order a copy of this article
    by Ashish Sharma, Jitendra Kaushik 
    Abstract: Permissible delay in payment is a common method of payment often used by the suppliers and it generally leads to higher sales and ultimately higher revenue. This method is significant in the case of deteriorating products. In this paper, an inventory model for the deteriorating items with price and time-dependent ramp type demand is presented. Shortages are allowed and partially backlogged. The solution procedure is illustrated by numerical examples. The concavity of the profit function with respect to the decision variable is discussed analytically. Numerical analysis shows that the profit per unit time increases with the delay payment facility.

  • Public Private Partnerships and Continuity of Government Service Delivery in the era of Coronavirus Outbreak in Sub-Saharan Africa   Order a copy of this article
    by Alex Nduhura, Lukamba Muhiya Tshombe, Thekiso Molokwane, Ivan Twinomuhwezi, Innocent Nuwagaba 
    Abstract: Public private partnerships (PPPs) remain a popular delivery mechanism by governments across the world. However, there is dearth of literature on popularity and performance of PPPs in the COVID-19 era, mainly in Sub-Saharan Africa (SSA) where PPP concessions in service delivery are new and increasing. The purpose of this study is to evaluate the effects of COVID-19 on PPP concessions and identify appropriate strategies to keep them afloat during uncertain times. Based on systematic review of literature and documents, the study noted that while pandemics such as bubonic plague; Spanish flu; HIV/AIDS; SARS; the avian bird flu and Ebola existed before, they did not plunge the whole world into largescale socio-economic disruption and lockdowns like COVID-19 pandemic. Continued delivery of public services through PPPs by governments may be frustrated by COVID-19 unless credit guarantee schemes; renegotiating concessions; finance for equity swaps and concession extensions are adopted as requisite strategies.

  • An optimising inventory model for investing preservation technologies in deteriorating products with hybrid type of price and stock dependent demand rate   Order a copy of this article
    by S.K. INDRAJITSINGHA, Anita Kumari Sahu 
    Abstract: The objective of this study is to examine the effect of preservation technology investment of an inventory system for instantaneous decaying items. In real life situation retailer’s invested capital in preservation technology leads to lower the rate of deterioration of the products. In this research, we developed an optimizing inventory system of preservation technology in decaying items by considering hybrid type of demand. The market demand of daily essential products fluctuates because of two demands: non-linear and linear. In view of the above two demands, we observe that the demand is price sensitive as well as stock dependent. Moreover, the aim of this proposed study is to obtain the optimum ordering cycle, optimum selling price, optimum preservation technology cost and maximum total profit. Three different numerical examples are provided as case study with sensitive analysis carried out to validation of the proposed model.

    by Wakhid Ahmad Jauhari, Pratik Shah, Milan Patel, Nita Shah 
    Abstract: In this paper, we formulate a mathematical inventory model for non-instantaneous deteriorating items under price sensitive and quadratic time dependent demand. Products in the inventory system are considered to be deteriorated at a constant rate after a certain time of periods. Preservation technology investments are taken into account to reduce the deterioration rate. The objective of the model is to find the optimal cycle time, selling price, preservation cost and ordering quantity in order to maximize the total profit of retailer. An iterative procedure is proposed to solve the mathematical problems and its application is validated with a numerical example. The results from sensitivity analysis show that by investing money in preservation technology, the retailer can set a cheaper selling price and increase the total profit. It is also observed that the changes in holding cost and cost price significantly affect the optimal values of selling price and cycle time.

  • Comparative analysis of public procurement and public financial management within Asia and Africa   Order a copy of this article
    by Mark Opoku Amankwa, Emmanuel Kweinor Tetteh 
    Abstract: As procurement processes in many developing countries are without transparency, addressing agency problems becomes necessary. This study reflects on public procurement and public financial management in a comparative analysis within Asia and Africa through the agency theory lens. With a descriptive case study design, the study utilises datasets from 100 Asian and African countries from 2002 to 2018. The distinctiveness of this paper is that it uses Public Expenditure Framework and Accountability procurement indicators to ascertain whether agency cost has increased in both continents. The results showed that Asia performed better than Africa in all the indicators except for voice and accountability and procurement complaint management. There is also clear evidence to suggest that procurement decisions reduce agency cost in Asia than in Africa. The study, therefore, concludes that Asian countries tend to converge more to international standards during procurement processes than African countries, which leads to efficient PFM outcomes.

  • Implementation of e-procurement for pharmaceuticals: Perspectives of the staff of the State Pharmaceuticals Corporation (SPC) of Sri Lanka   Order a copy of this article
    by Prasanna Dinesh Koggalage, K.M.D.R. Dassanayake, P. K. S. S. Kulasuriya 
    Abstract: Public procurement is pivotal to governments, not only to deliver public goods or services but also, ensuring value for money. Electronic Procurement, through Information and Communication Technology improves the efficiency and transparency of public procurement. The State Pharmaceuticals Corporation of Sri Lanka (SPC) procures pharmaceuticals for state health sector in Sri Lanka, but its traditional procurement system has inefficiencies, leading to delays affecting patient care services. Hence, introduction of an e-procurement system is important. This cross-sectional study obtained perspectives of the staff of SPC towards implementation of an e-procurement system through a self-administered questionnaire administered to all relevant staff members (60 respondents). It revealed that the majority was dissatisfied with the existing system which is less efficient, costly and less user-friendly. The majority expected that e-procurement will improve efficiency and user-friendliness.

  • A Stackelberg game for ordering and pricing policies in a decentralized dual-channel supply chain   Order a copy of this article
    by Mohammadali Pirayesh, Farzad Dehghanian, Fariba Soleimani 
    Abstract: This study explores ordering and pricing policies in a decentralized two-echelon dual-channel supply chain including one manufacturer and one retailer. The manufacturer produces in a lot to supply an integer number of the retailer’s order and also to meet the demand of direct sales channel. It is assumed that the manufacturer has more market power than the retailer and he is the leader of a Stackelberg game. The concavity of the manufacturer profit function is proved which based on it a solution procedure is proposed by using game theory and Nelder-Mead algorithm to find the optimal pricing and ordering policies for the manufacturer and the retailer. The numerical example is provided to investigate the features of the proposed model. It is shown that, the inventory holding costs, setup costs and ordering costs have negligible effects on optimal prices and also by increasing the price elasticity of the demand of one channel to the price of the other channel, both members can achieve more profit.

  • Constraints to incorporate competition in Public-Private Partnerships (PPP) in Malaysia   Order a copy of this article
    by Akila Pramodh Rathnasinghe, Udayangani Kulatunga, Muhammad Imran Zin Zawawi 
    Abstract: Competition in procurement not only benefits government and taxpayers but also provides an equal market for the private sector. Competitive procurement stimulates market creativity, as it discourages anti-competitive behaviour. Despite the complexity of the PPP procurement process, the world is now promoting competition within it, an element yet to be fully implemented in Malaysia. This paper analyses the constraints that Malaysia faces in effectively maintaining PPP competition. Within the case study research strategy, semi-structured interviews and content analysis were used as data collection and analysing methods. The study found that in its efforts to make the PPP programme a success, the Malaysian PPP has followed flexible implementation, with less emphasis on competition. The effect of focusing only on PPP's macro aim has resulted in a lack of competition. The current challenge is to strike a balance between achieving aims and maintaining governance and therefore getting the best out of PPP,

  • Optimisation on multi-period raw material procurement and product mixing under uncertain demand via probabilistic multi-objective model approach   Order a copy of this article
    by S. Sutrisno, S. Solikhin, Purnawan Adi Wicaksono 
    Abstract: Raw material procurement and product mixing planning are two important components in manufacturer industries, based on the fact that they contribute significantly to production cost and profit. This article describes a newly developed mathematical model in the form of multi-objective optimisation, as an alternative approach that is possibly used to improve a multi-period raw material procurement and product mixing plan under uncertain demands. This process is initiated by the formulation of two objective functions, including the amount of the output to be produced, which ought to be maximised, and the minimisation of raw material procurement cost. Subsequently, a weighted objective function was formulated for use in the calculation of Pareto solution, and the optimisation problem was resolved to obtain ideal values for all decision variables. In addition, numerical experiments were also performed, in the model evaluation, resulting in the peak value for each decision variable.
    Keywords: raw material procurement; product mixing; bi-objective optimisation; Pareto optimal.

  • The impact of power on the depth of sustainability collaboration in the supply chain network for Australian food retailers   Order a copy of this article
    by Hadi Rezaei Vandchali, Stephen Cahoon, Shu-Ling Chen 
    Abstract: The purpose of this paper is to investigate the impact of supplier power within supply chain networks (SCN) on the depth of sustainability collaboration with their focal firms. A web-based survey was applied to two large Australian retailers' SCNs which resulted in receiving 67 completed questionnaires. A cluster analysis was conducted to create a suppliers' power taxonomy. ANOVA and Tukey tests were also used to explain the mean differences in the depth of collaborative relationships. This paper identifies four quadrants for suppliers based on their power at both network and node levels, highlighting the impact of power on the depth of collaboration in each quadrant. The results also indicate that the depth of collaboration between the focal firm and its suppliers increases when the suppliers' power increases at the network level and decreases at the node level.

    Abstract: This study aims to synthesise knowledge about big data (BD) in the area of purchasing and supply management (PSM) and to develop an agenda for future research. A systematic literature review approach was employed, and 65 articles were synthesised based on a classification for BD in PSM to identify research gaps and opportunities. Literature in this area is descriptive and conceptual in nature, and modelling methods are favoured. BD applications were identified for supplier selection, supply risk management, and supply visibility. Based on the complexity of access and use of BD, we identify a need for contextualised theory-building studies.

  • Affective-cognitive nature of engagement: correlating psychological capital and core-self-evaluations to work engagement via positive affects   Order a copy of this article
    by Maryam Firouznia, Seyed Hasan Hosseini, Mohammad Mehdi Maleki Karamabad 
    Abstract: The objective of this paper is primarily to hypothesise that personal resources, positive affects and work engagement are reciprocally associated with each other. In particular, by applying broaden-and-build theory, it seeks to demonstrate the predictive value of positive affects and individual resources for engagement by incorporating both core-self-evaluations and psychological capital as individual-level determinants of engagement. The research methodology is qualitative with the empirical field. The qualitative data analysis was conducted using content analysis. Hence, it is developmental at result and applicable from goal perspective. With reference to empirical studies and existing research on engagement, the proposed conceptual models through three gain spirals confirms the reciprocal relationships of personal resources-positive affects, positive affects-work engagement, and finally work engagement-personal resources, which is in accordance with the cognitive-affective state of engagement. The study can deepen the insights on how individual resources and positive affects interact in their contribution to work engagement. More importantly, this paper is the first to elucidate the cognitive-emotional nature of work engagement via presenting a comprehensive gain cycle considering individual resources as a cognitive representative, on the one hand, and positive emotions as an affective representative on the other hand.

    by Azar Kaffashpoor, Mosayeb Samanian, Hadi Rahmdel 
    Abstract: The purpose of this study was to design and explain a model of professional ethics for bank managers, and also identifying its dimensions and components. The research strategy used in this study is the grounded theory with a Glaserian (emergent) approach. To collect the data, a semi-structured targeted sampling (using the snowball method) was conducted. Fifteen interviews with bank managers were done to reach a theoretical conclusion. The required data were collected and analysed. After the continuous process of data comparison and selective codifying, the total collected data were classified into 403 primary concepts, 23 categories and three groups. The final result of the collected data analysis led to the final model of research about the core issue, as the 'professional ethics for bank managers'. The bank manages' professional ethics were classified into three dimensions: individual, organisational and cross-organisational. Based on the findings of this study, this model can be considered and used as a guide for organisational and professional ethics for bank managers.

  • Emotional intelligence in procurement management   Order a copy of this article
    by Dirk-Jan F. Kamann, Edit M. Kővári 
    Abstract: This contribution describes the role of emotional intelligence (EI) in procurement management (PM) and how to successfully operationalise and measure this concept. A literature review presents a well-tested questionnaire, which is applied in a survey among members of a national professional organisation in PM. These managers' self-control is found to be higher than in other surveys with other types of managers; their well-being level however is lower. This suggests that PM managers can control their emotion well, but they 'pay the price' in their happiness, optimism and self-esteem. In addition, male managers' self-control and well-being is found to be higher than their female counterparts. Demonstrating the possibility to operationalise EI in a reliable way, this study opens an agenda to relate various EI dimensions to a vast range of endogenous variables such as performance variables and exogenous variables like customer typology, nature of the supply system or the internal arena.

  • An inventory model with stock-dependent demand under trade-credit policy and fixed life-time   Order a copy of this article
    by Nita H. Shah, Kavita Rabari, Ekta Patel 
    Abstract: In inventory management, deterioration has a great impact on total profit. To develop business strategies in competitive market, stock-dependent and price-sensitive demand rate is considered to attract more customers. The holding cost and deterioration rate are time-dependent. The product considered has fixed life-time. The model considers the trade-credit policy that is the retailer will offer a certain time period to the customers to settle the account to increase the sales during the permissible period. The objective is to maximise the total cost with respect to cycle time and selling price. The classical optimisation method is used to find the optimal solution. A sensitivity analysis of optimal solutions for different inventory parameters is carried out. The managerial insights are deduced for the retailer.
    Keywords: selling price; deterioration; trade-credit; stock-dependent demand; time-dependent holding cost; sensitivity.
