Greening the Supply Chain: Drivers and Outcomes in the Korean Manufacturing Industry

This research investigates the determinants of green supply chain management(GSCM)adoption and its impact on organizational performance,while considering the potential moderating factors influencing GSCM adoption.Despite the growing prevalence of GSCM practices among Korean firms,the factors driving their adoption have not received sufficient attention.To bridge this gap,the study uses structural equation modeling,integrating stakeholder theory and resource-based theory to explore how green entrepreneurial orientation(GEO),institutional pressure,and relational capital affect GSCM adoption.Additionally,the study explores the effects of GSCM implementation on competi­tiveness and economic performance.Drawing data from a sample of 213 Korean manufacturing firms,the PLS-SEM analysis highlights the significant influence of GEO,institutional pressure,and relational capital on GSCM adoption.Additionally,the study emphasizes the positive impact of GSCM implementation on firm competitiveness.These find­ings provide valuable insights for enhancing sustainability in supply chain management and are applicable to similar context countries such as Taiwan,China,Japan,and the Netherlands.

Optimum Design of Stair-Climbing Robots Using Taguchi Method

Environmental issues like pollution are major threats to human health.Many systems are developed to reduce pollution.In this paper,an optimal mobile robot design to reduce pollution in Green supply chain management system.Green supply chain management involves as similating environmentally and eco-nomically feasible solutions into the supply chain life-cycle.Smartness,advanced technologies,and advanced networks are becoming pillars of a sustainable supply chain management system.At the same time,there is much change happening in the logistics industry.They are moving towards a new logistics model.In the new model,robotic logistics has a vital role.The reasons for this change are the rapid growth of the e-commerce business and the shortage of workers.The advantages of using robotic logistics are reduction in human errors,faster delivery speed,better customer satisfaction,more safety for workers,and high workforce adaptability.A robot with rocker-bogie suspension is a six-wheeled mobile platform that has a distinctive potential to keep all wheels on the ground continuously.It has been designed to traverse rough and uneven terrain by distributing the load over its wheels equally.However,there is a limitation to achieving high-speed mobility against vertical barriers.In this research,an optimal design of product delivery wheeled robots for a sustainable supply chain system is proposed to ensure higher adaptability and maximum stability during climbing staircases.The design parameters of the proposed robot are optimized using Taguchi Method.The aim is to get a smooth trajectory of the robot’s center-of-mass.The proposed approach realizes a robot with much-improved stability which can climb over heights more than the size of the wheel(i.e.,3 times the radius of wheels).The results reveal that the modified rocker-bogie system not only increases the stair-climbing capability but also thwarts instability due to overturning of a wheel of the robot.

Analysis of Sustainable Materials Used in Ecovillages: Review of Progress in BedZED and Masdar City

This paper explores reclaimed and recycled material used in ecovillages. The models discussed in this paper include BedZED in the United Kingdom and Masdar City in the Middle East. These two communities contain features characterized by the sustainable principles of the ecovillage concept by using non-traditional building materials. The creations of more ecovillages, along with the growth of current ecovillages, play an important role in positively solvening environmental and social problems. The sustainable materials used in the ecovillages also act as a model for communities wishing to implement sustainable development.

Retailers'incentives for green investment in differentiated competition channels

With increasing public environmental awareness,green activities in retail and distribution processes have become crucial tools for retailers to boost demand and enhance competitiveness.This study develops an analytical model to study the green investment choices of two differentiated retailers dealing with a common green manufacturer.It also explores the impacts of these investment choices on the manufacturer's operational decisions,channel efficiency,consumer welfare,and the environment.We derive three main results.First,the powerful retailer always favors green investments,whereas the less powerful(inferior)retailer may either prefer or avoid green investments.The fiercer the interretailer competition,the lower the willingness of the inferior retailer to introduce green investments.Second,although all supply chain parties may disagree on their preferences for retailers'green investments,a bilateral green investment(i.e.,both retailers make green investments)can reach an incentive alignment for all firms if the differentiation between retailers is low enough and the competition between them is not substantially fierce.Moreover,a bilateral green investment improves consumer welfare and channel efficiency because of the great demand expansion and double marginalization reduction.Third,the retailers'green investments can motivate the manufacturer to produce greener products,but they do not necessarily benefit the environment.We show that the supply chain's economic sustainability aligns with its environmental sustainability only if the environmental improvement efficiency of green investments is substantially high.We further examine the impact of retailers with differentiated green investment abilities and the manufacturer's green investment efficiency to verify the robustness of the main results.

Green managerial practices and green performance:A serial mediation model

This study examines the influence of green supply chain management(GSCM)practices and green culture on green performance in the manufacturing sector through the mediating effect of proactive environmental strategy(PES)and green product innovation(GPI).A quantitative approach was followed,and partial least squares structural equation modeling(PLS-SEM)was used for hypothesis testing.A questionnaire was used to collect data,and 663 questionnaires were included in the final analysis.Contrary to our expectations,the results showed that GscM practices do not influence green performance,whereas green culture is positively related to green performance.The results show that PES and GPI explain the relationship between GSCM practices,green culture,and green performance.PES and GPI sequentially mediated GSCM practices,green culture,and green performance.Moreover,PES and GPI significantly improved green performance.This study aims to extend the scholarly appreciation of GscM practices and the impact of green culture on green performance by examining the mediating effects of PES and GPI on these relationships.The implications and future research avenues are also discussed.
