by A. A. Gde Putra Pemayun, Ni Nyoman Sunariani
Abstract: Indian mobile services endeavour the second largest stand in the worlds rank with the proliferated subscription. Mobile operators surface ceaseless competition with a vibrant market scenario as customer churn rates are acute. The study inducted to develop measures and validate the scale of customer churn in the Indian mobile services sector. A total of 1,102 customers were surveyed and structural equation modelling was instrumented to authenticate the reliability and validity of the customer churn scale. Price, corporate image, service quality, and customer relationship management have emerged as significant factors to influence the churn behaviour of customers in the Indian telecom sector. Even though mobile operators devise proactive strategies by investing and devising customer retention campaigns, they could not resist the ascending churn rates. This research paper recommends a validated scale to predict the customer churn in Indian mobile services sector as it is proliferating as well as the exponent in predominant churn rates. This unique study would encompass the contribution to the comprehensive development of customer churn scale in the Indian mobile services sector.

by Ida Ayu Oka Martini, A. Ngurah Eddy SupriyadinathaGorda, I. Gusti Ayu Wirati Adriati, Ni Ketut Elly Sutrisni
Abstract: This study aims to examine and analyse the influence of the dimensions of competence and work creativity on worker performance, as well as the role of work created in mediating the relationship of competence with the performance of weaving workers. This research was conducted on weaving workers in Bali Province. The number of research samples is 117 weaving workers, which are taken proportionally from 2,268 community workers spread across seven districts/cities. The determination of the number of samples is based on the Slovin formula with a precision of 7%, and the number of samples in each district is determined proportionally. The determination of workers who were respondents in the study was conducted randomly. Data collection is done by distributing questionnaires to research respondents. Furthermore, the data were analysed using the SmartPLS 3.0 Program. The results of the analysis show that work competencies (knowledge, skills and attitudes) and work creativity have a significant positive effect on the performance of weaving workers. Likewise, work creativity is positively significantly influenced by work competency. Furthermore, the results of the analysis also prove that work performance plays a role as a mediator in the relationship of competence with the performance of weaving workers in Bali.

The Effect of Social and Regulatory forces on Voluntary Restatement of Earnings: Evidence from Nigerian Logistics Firms
by Muhammad Sadiq, Abdurrahman Adamu Pantamee, Shafi Mohamad
Abstract: This paper examines the factors motivating firms to voluntarily disclose past wrongdoings and restate earnings aided by the imposition of social and regulatory forces. We incorporate the data of 80 listed firms on the Nigerian Stock Exchange (NSE) from 2008-2018 using 800 observations. Our results support the decision for the voluntary disclosure of past wrongdoings and restatement of earnings. However, the results are positive when informal social forces act to encourage firms to restate earnings and negative when formal forces like regulatory bodies act to forcefully restate the earnings. The results are consistent with our hypothesis and serve as the basis for further research in this area.
Keywords: voluntary disclosure; voluntary restatement; formal forces; informal forces; corporate governance.
Evaluation of inventory replenishment policies on supply chain performance with grey relational analysis
by Joby George, V. Madhusudanan Pillai
Abstract: The objective of this paper is to evaluate various Inventory Position-based (IP-based) and Non-Inventory Position-based (NIP-based) replenishment policies on the performance of a serial supply chain having four stages: manufacturer, distributor, wholesaler and retailer. The IP-based policies use inventory position-based information for replenishment whereas NIP-based policies do not require such information. The performance indicators are supply chain fill rate, bullwhip effect and total cost of supply chain. An experimental study is conducted using a simulation model under no information sharing and mean customer demand information sharing scenarios and the policies are ranked for each scenario using grey relational analysis. This analysis shows that the performance of the supply chain is better when NIP-based policies are used. The statistical analysis of the impact of information sharing among the supply chain members shows that the information sharing strategy has an impact on the performance of supply chain when IP-based policies are used.
Keywords: supply chain; inventory replenishment policy; fill rate; bullwhip effect; inventory position; reorder level; performance indicator; simulation; information sharing; grey relational analysis.
Blockchain: a game changer in electronic waste management in India
by Karishma Chaudhary, Prasanna Padmanabhan, Deepak Verma, Prashant Yadav
Abstract: In 2016, 44.7 million metric tonnes of Electronic waste(e-waste) was generated across the globe out of which only 20% was recycled through formal channel. India is fifth largest generator of e-waste where 95% of e-waste is channelled to unorganised units. There are substantial environment and health risks associated with unsafe e-waste management practices. The study highlights various blockchain based applications in waste management domain. The study deals with the development of Ethereum-based smart contract blockchain architectural platform 'e-waste lens' for effective e-waste management in India. The specific novelty of the blockchain architectural framework lies in the real-time tracking and monitoring of e-waste movement by the concerned stakeholders in the e-waste management chain and thereby bringing out the non-compliance of the prevailing regulations for effective e-waste management.

Operational Risk Management: Analysis of Challenges faced by banks in India
by Barkha Jadwani, Shilpa Parkhi
Abstract: Operational risk management is gaining significance in todays dynamic banking environment especially due to the technological disruptions faced by Indian Banks today. The objective of this research paper is to analyse the issues faced in management of operational risk. This paper uses a questionnaire-based interview of senior banking professionals to analyse the challenges in operational risk management. It is more complex as compared to other banking risks and in that context an in-depth analysis of the various issues/challenges has been done. Operational risk incidents in banking industry have increased significantly. Such incidents are non-repetitive so historical trends are not useful here. Availability of data is also one major constraint. The Banking system in India should be very proactive in constructing a robust operational risk management framework. Operational risks should be properly managed else it can have serious implications on the reputation of the bank.
Keywords: operational risk; banks; Basel; risk management; operational risk management regulations; analysis of frauds; management oversight; effects of technology on operational risk; causes of frauds.
A Bibliometric Analysis of Trends in Electronic Service Quality Research Over Two Decades
by Kala Mahadevan, Sujata Joshi
Abstract: This paper encapsulates published research literature on electronic service quality through a bibliometric analysis using the Scopus database and bibliometric and graphical visualisation tools such as Biblioshiny and VOSviewer. The literature is investigated over a two-decade period (1999 to 2019) in order to assess citation trends, top contributing countries, journals and authors and establishing network visualisation patterns such as keyword co-occurrences, co-authorship linkages and citation analysis. USA and Taiwan dominate research in this field in terms of articles published as well as citations. It is found that research largely pertains to the conceptualisation, measurement and evaluation of electronic service quality followed by focus on constructs like value, satisfaction, loyalty and behavioural intentions. Electronic commerce and Banking are the key industries for research in this area. This paper aims to offer researchers a quick snapshot and mapping of research trends which would provide a guideline for future research in this area.

The impact of intelligent automation in internal supply chains
by Tiago Coito, Joaquim L. Viegas, Miguel S.E. Martins, Bernardo Firme, João Figueiredo, Susana M. Vieira, João Miguel Da Costa Sousa
Abstract: Nowadays, industry is being forced to produce smaller and more diverse batches, increasing the complexity of internal supply chains. Data has become a valuable asset, supporting the development of intelligent automation solutions. Decision support systems, which leverage data, require the automation pyramid to be more flexible, as information needs to be exchanged simultaneously and in real-time with all automation layers. This paper proposes a framework for intelligent automation to deal with current challenges in acquisition and management of data in industrial settings, towards feeding decision support systems. It frames the topic within the scope of internal supply chains, addressing the framework impact on work practices within the organisation. Two real industrial implementation cases are examined, in the wood and chemical industries. Results help practitioners address the most impactful challenges affecting the performance of internal supply chains, by developing systems which are faster, more flexible, efficient and with improved quality.

Integrated operational supply chain planning in Industry 4.0
by Matheus Cardoso Pires, Renato Parreira, Enzo Morosini Frazzon
Abstract: The scenario of isolated companies competing with each other has evolved to a holistic vision, where companies collaborate and work together to maintain supply chain competitiveness. Integrated supply chain planning, although challenging, is necessary to foster competitive advantage and to ensure companies' survival in difficult times. Concepts and technologies introduced by the Fourth Industrial Revolution support such integrated planning models. This paper presents a systematic literature review on integrated supply chain planning aiming to identify research streams, opportunities and the impact of Industry 4.0. The study identified the lack of research on supply chain planning which considers Industry 4.0 concepts and opportunities. Five prevailing research streams stand out: 1) approaches to deal with complexity; 2) the consideration of uncertainty; 3) raw material inventory control and procurement processes; 4) the necessity of considering environmental impacts; 5) particular models for dealing with limited lifetime products. Finally, the following future research opportunities were identified: 1) improving decision-making models to consider stochastic and dynamic behaviours; 2) extending the models to include larger networks with more variables; 3) developing more efficient solving approaches.

A measurement model of value of data for decision-making in the digital era
by Ganesh Sankaran, Martin Knahl, Guido Siestrup, Ismini Vasileiou
Abstract: Despite burgeoning opportunities for data-driven decisions, research shows that decision makers are failing to make sense of data within a broader context of organisational change which presents the following pertinent questions: 1) How can decision makers measure the value of data by giving a holistic account?; 2) How should the organisation-specific blending of machine and human rationality be factored in the measurement model? This study tackles these questions by proposing a novel approach that combines system dynamics and the ability to incorporate data science methods. In addition to a conceptual description, this paper also describes a feasibility test conducted on a small-scale prototype set in a supply chain context. The results show that the use of sophisticated models that have a local scope ('locally rational') might have unintended global consequences. It underscores the need for a holistic model in the decision makers' toolkit providing the ability to run targeted simulations to assess digital investments.
Keywords: digital technologies; digital transformation; data-driven decisions; big data; quantifying value of data; bounded rationality; system dynamics; human-AI collaboration; supply chain management.
Flows optimisation of industrial symbiosis based on bi-objective mathematical modelling
by Hajar Nouinou, Daniel Roy, Sophie Hennequin
Abstract: It seems clear that industrial systems can no longer continue to operate by taking unrestricted amounts of natural resources, especially when these are non-renewable. In order to limit this over-consumption, the industrial symbiosis principle is an interesting solution. The objective here is to determine, using a mathematical bi-objective model, the optimal flow allocations within a symbiosis. Our model applies at the tactical and operational levels, i.e., when the symbiosis is already defined. The aim is to study the best possible flow distribution in order to maximise both the symbiosis overall economic and symbiotic profits (defined as the difference between internal and external flows). With this in mind, we will conduct a numerical application based on a real example with generic values before presenting an optimisation algorithm based on the ε-constraint method. Finally, simulations will be performed to study the evolution of results.
Keywords: industrial symbiosis; mathematical modelling; optimisation; materials flows; waste management.
Recycle system design for end-of-life electronics in developing countries
by Pedro M. Reyes, Jianghong Man, Patrick Jaska, John K. Visich, Michael J. Gravier
Abstract: This paper examines recycling of end-of-life products in developing countries to determine the most reasonable collection policy in order to increase profits. The process of self-recycling by original manufacturers is examined using simulations. The simulations were based on three different investment percentages for collection versus refurbishment/remanufacture for end-of-life products. Results offered here can help decision makers understand trade-offs they face as they decide how to best process returned products (refurbish, remanufacture, or recycle). Simulations of the various collection policies for end-of-life products suggest that original manufacturers in developing countries experience better profit results from collection policies that favour developing refurbishment and remanufacturing capabilities over collection. Furthermore, eco-design bolsters profitability and efficiency of self-recycling systems under all conditions, whereas supplier partnership for environmental design only improves outcomes when the original manufacturer invests in its refurbishment and remanufacturing capabilities.
Keywords: simulation; recycle; end-of-life; remanufacture; system dynamics modelling.
