Abstract
Purpose
This paper aims to investigate the features of three vectorized iterative numerical schemes used to simulate the behavior of modified Burgers equation (MBE).
Design/methodology/approach
Two of the schemes comprise differential quadrature and finite difference methods, while the third scheme consists of only differential quadrature for the derivative approximations. Proposed schemes are simulated for well-posed problems of MBE having known the analytic solution. The computational complexity of the schemes is examined through monitoring the time taken to complete the simulation. The results are compared with the analytic solution with the help of discrete error norms. Also, the accuracy of the proposed schemes is compared with that of the existing schemes in the literature. Vectorized MATLAB programs of the schemes are used for all investigations.
Findings
It is observed that all the three schemes succeeded in producing a good replication of the exact solution. The results are closer to the analytical solution than the results in the literature. Among the three schemes, the scheme labeled as FDTDQS is found highly accurate and computationally cheaper using fewer grid points. From the vectorized MATLAB programs provided, it is evident that the implementation of the schemes is simple.
Originality/value
This study gives an idea about three numerical schemes for a highly nonlinear problem. This mathematical framework can be adopted to any one-dimensional partial differential equation as well, and the provided program will be helpful to generate more fast and accurate vectorized code in MATLAB.

Abstract
Purpose
This study aims to provide a scientific framework for the selection of suitable substation technology in an electrical power distribution network.
Design/methodology/approach
The present paper focuses on adopting an integrated multi-criteria decision-making approach using the Delphi method, analytic hierarchy process (AHP) and technique for order preference by similarity to ideal solution (TOPSIS). The AHP is used to ascertain the criteria weights, and the TOPSIS is used for choosing the most fitting technology among choices of air-insulated substation, gas-insulated substation (GIS) and hybrid substation, to guarantee educated and supported choice.
Findings
The results reveal that the GIS is the most preferred technology by area experts, considering all the criteria and their relative preferences.
Practical implications
The current research has implications for public and private organizations responsible for the management of electricity in India, particularly the distribution system as the choice of substations is an essential component that has a strong impact on the smooth functioning and performance of the energy distribution in the country. The implementation of the chosen technology not only reduces economic losses but also contributes to the reduction of power outages, minimization of energy losses and improvement of the reliability, security, stability and quality of supply of the electrical networks.
Social implications
The study explores the impact of substation technology installation in terms of its economic and environmental challenges. It emphasizes the need for proper installation checks to avoid long-term environmental hazards. Further, it reports that the economic benefits should not come at the cost of ecological degradation.
Originality/value

Abstract
Purpose
E-commerce refers to the facilitation and delivery of goods and services to the customers employing an electronic arrangement. For an e-commerce firm, the customer service level provided by its suppliers can make or break the firm. The purpose of this research is to help e-commerce enterprises in addressing the vast challenge of complex supplier selection and evaluation process that must be performed vigilantly.
Design/methodology/approach
The present study utilizes a three-pronged approach that integrates supplier management practices with the operational business practices of an e-commerce enterprise. In the first step, key performance factors for e-commerce capable suppliers are identified through an expert opinion and existing supplier management literature. Further, Data Envelopment Analysis (DEA) is employed to obtain the efficiency score for each supplier that enables their ranking on various performance parameters. Lastly, the suppliers are classified into different categories based on their performance and efficiency.
Findings
Under the proposed classification scheme, top five suppliers, i.e. supplier 1, 7, 9, 11 and 17 are categorized as HE (High Performance and Efficient). It is suggested that e-commerce enterprises must build long-term relationship with the identified top performing suppliers. The study also provides real insights into supplier's performance on a number of objective criteria. Further, the present study enhances the overall performance and productivity of an e-commerce firm by achieving input cost minimization and output quality maximization, simultaneously.
Research limitations/implications
The results are valid for e-commerce enterprises in general. However, the present DEA model can be further evolved when applied in case of any particular e-commerce enterprise depending upon the internal capabilities of that firm. The nuances related to a firm's own supply capability development can be further explored by practitioners and researchers.
Practical implications
The proposed approach is expected to motivate decision-makers to consider using more sophisticated approached like DEA in supplier evaluation processes. Also, as a benchmarking technique, the proposed supplier classification approach is expected to be highly useful for practitioners in real-life settings.
Originality/value
The novel contribution of this study includes the supplier evaluation, ranking and classification for e-commerce enterprises based on the real-life data. The insights would help the practitioners to formulate novel strategies for appropriately investing in supplier relationships.

Abstract
Purpose
Development project implementation involving ecological and social externalities is an iterative process due to dynamic challenges emerging from the need to reconcile multiple, and often conflicting, interests of stakeholders. Stakeholder interactions result in learnings for project developers as well as policy makers. This paper aims to track corporate-civil society organizations-state interactions and learnings in case of a port development project in an eco-sensitive and socially challenging region of India.
Design/methodology/approach
The authors try to unpack the interactions among various stakeholders in the case of development of Dhamra Port being developed by the Dhamra Port Company Ltd, in the state of Orissa, India.
Findings
The authors find that sustainable development policy formulation and implementation is an evolutionary process involving plugging of governance gaps at each successive stage with civil society actors playing an active role.
Research limitations/implications
The study is based on single case of a major port development in India.
Practical implications
The paper highlights that development in emerging economies through large projects is unavoidable. The development-sustainability dilemma cannot be overlooked any further; rather, it needs to be resolved with complete participation of all involved stakeholders.
Originality/value
The paper provides account of long and complex interactions among various players involved in developmental project in an emerging economy. The learnings from the paper will be relevant for policymakers, corporate executives and civil society activists.

Abstract
Learning outcomes
This case study attempts to sensitize the impact of restructuring on the organization’s employer brand. The students shall learn to appreciate the criticality of maintaining a balance between being an employee-centric organization and building a sustainable business model, to analyze the alternative people management strategies in emerging start-ups.
Case overview/synopsis
This case study illustrates the innovative human resource (HR) policies adopted by the start-up Meesho. Meesho was started as “Fashnear” by two Indian Institute of Technology graduates Sanjeev Barnwal and Vidit Aatrey in the year 2015, with the headquarters located in Bengaluru, Karnataka, India. It was a social commerce platform wherein the local apparel sellers or manufacturers could register themselves on the app and sell their products online to nearby consumers and the product would be delivered to their homes. Later, it was renamed Meesho (Meri E-Shop) with an improved business model. The innovative people-centric policies got Meesho recognition as one of the most employee-friendly start-ups and an innovative employer. However, later as part of the restructuring exercise, it had to lay off employees, which had a counter impact on its reputation and image as a desirable employer. This case study captures the dilemma faced by start-ups like Meesho who were in the process of sustaining their growth and optimizing their workforce and, at the same time, have to manage their employer brand in the process.
Complexity academic level
This case study can be used at the postgraduate level of management and in executive management programs.

Abstract
Purpose
Considering food waste as a global problem resulting from the wastage of valuable resources that could fulfil the requirements of malnourished people, the current research focusses on understanding consumerism’s impact on this phenomenon. Additionally, the circular economy (CE) approach can be critical in reducing food waste and promoting sustainability.
Design/methodology/approach
A systematic literature review was conducted using bibliometrics and network analysis. The study reviewed 326 articles within 10 years, from 2013 to 2023.
Findings
The findings reveal four prominent factors – behavioural, environmental, socioeconomic and technological – in managing food waste (FW). Reducing FW at a holistic level can benefit individuals and the environment in several ways.
Research limitations/implications
Consumers are encouraged to be more responsible for their food consumption by reducing food waste, as it affects societies and businesses both economically and environmentally. This can help promote a responsible consumption culture that values quality over quantity and encourages people to make more informed choices about what they eat and how they dispose of it post-consumption. All stakeholders, including firms, the government and consumers, must examine the motives behind inculcating pro-environmental behaviour.
Originality/value
Addressing consumerism and the ability to decrease FW behaviour are complex issues that require a multidimensional approach. This study seeks to fill the gap in understanding consumerism and the capacity to reduce FW using the CE approach and understand the research gaps and future research trends.

Abstract
Purpose
Information-facilitated product recovery system (IFPRS) has captivated industry attention and has developed into a matter of consideration among the researchers because of enhanced climate concerns, jurisdictive logics and societal liabilities. Although IFPRS implementation has become an essential aspect in manufacturing industries functional in the developed nations, still, limited consideration has been given in the literature to analyze the issues to IFPRS implementation for a circular economy (CE) in emerging and developing nations. Therefore, the objective of this study is to recognize issues to implementing IFPRS for a CE in context of select manufacturing industries in India.
Design/methodology/approach
In this study, 24 potential issues are established from the literature and from suggestions from the experts. The issues are clubbed under five different perspectives of technical, government, organization, policy and knowledge. Further, fuzzy VIKOR technique is applied on the results obtained to prioritize the identified issues. A sensitivity analysis has been carried out to check the robustness of the framework.
Findings
The present study shows that lack of skills and expertise in IFPRS implementation for a CE (I2), deficient capital to implement a CE in IFPRS (I9), inadequate in adopting recent IT technology (I18), feasibility of IFPRS employment for a CE (I6) and no efficient training and program to CE adoption (I21) are the top five potential issues in implementing IFPRS practices for a CE in Indian manufacturing industries.
Research limitations/implications
In literature, limited study has been observed on determining issues to implementation of IFPRS for a CE. A more systematic method and statistical confirmation is necessary to establish further new confronting issues. This study is limited to Indian manufacturing industries.
Originality/value
The main contribution of this study includes identification of issues and later prioritizing them to reflect their severity. This would help the industry practitioners to formulate strategies for handling the issues conveniently.
