Abstract

The purpose of this study was to achieve supply chain sustainability by considering Just in Time (JIT) in return vehicle usage. In response to a general increase in modern environmental awareness, consumer and government attention towards product and service compliance with environmental protection standards has increased. Consequently, manufacturers and stakeholders are pressured to use eco-friendly supply chains. In this paper, we analyzed the JIT model, a transportation network that ensure agile responses and delivery of goods in a supply chain, which reduces inventory costs. We then compared two return vehicle transportation scenarios. In the first, goods were transported from the central warehouse to the distribution base, and the return vehicle delivered recyclable packaging materials back to the central distribution warehouse. In the second scenario, goods were transported from the manufacturer to the distribution center (warehouse) more frequently, leading to reduced inventory. We then utilized the aforementioned JIT system with ILOG CPLEX12.4 to ascertain which scenario would produce the lowest carbon emissions for the lowest total cost.

Highlights

People’s growing concern about whether or not the commodities they purchase are environmentally friendly and energy saving has gradually exerted an influence on consumer purchasing behavior, leading to a boom in green supply chain developments, which covers green purchases, manufacturing, green consumption, recycling, green logistics, etc. [1,2]
Based on a compilation of state-of-the-art green supply chain literature, Srivastava [4] proposed that its main focuses are green operations, green design, reverse logistics, network design, green manufacture, re-manufacture, and waste management
After transporting goods to the distribution base, the return vehicle was used to send the packaging material back to the distribution center so that it could be reused in the supply chain

Summary

Introduction

People’s growing concern about whether or not the commodities they purchase are environmentally friendly and energy saving has gradually exerted an influence on consumer purchasing behavior, leading to a boom in green supply chain developments, which covers green purchases, manufacturing, green consumption, recycling, green logistics, etc. [1,2]. Companies that have implemented the sustainable green concept have been shown to have a better operational and organizational performance [8] This trend is environmentally friendly but will enhance enterprise competitiveness through supply chain network integration [3]. A greater number of companies have chosen to hire third-party specialists to handle logistical distribution in the supply chain [18] This has been shown to reduce transportation costs and to improve service and operational efficiency [19]. The packaging materials can be recycled at each point collection when the items are delivered to the bases The purpose of this scenario is to make the supply chain more environmentally friendly and reduce the overall carbon emissions.
