Abstract

In the green supply chain approach, all the links that are put together to provide a product or service are considered, and strategic and operational decisions are made to increase the efficiency and effectiveness of the entire chain. At the same time, the environmental effects should be minimized. In this research, a nonlinear mixed-integer multiobjective model is developed to design a green closed-loop supply chain for medical products. In this supply chain, the echelons include supplier, manufacturer, warehouse, and customer in the forward supply chain and collection centers, repair services, and disposal centers in the reverse supply chain. In the proposed model, four objectives of customer satisfaction, environmental effects, supply risk, and total costs of the supply chain were considered. The developed model is implemented in a supply chain of medical products, and after optimizing the model, the main results including location and capacity of facilities, planning for flexible production, purchase of materials, service and maintenance plan, product transfer, and inventory level are determined and analyzed.

Highlights

Nowadays, many companies are trying to improve their business processes to meet customer expectations and satisfaction and be able to compete successfully in competitive environments
Considering the issues raised in the field of the green supply chain, the main purpose of this study is to continue the research conducted by other researchers who, leaving aside some of the assumptions that facilitate and limit supply chain issues, present their proposed models. e problem should be developed in such a way that its assumptions are more compatible with real-world conditions, so the purpose of this study is to develop a multiobjective green supply chain model that includes supplier, manufacturer, and customer levels in the forward supply chain and collection, recycling, and disposal centers in the reverse supply chain
In the first scenario, the first customer has a demand for the first product, and in the second scenario, there is a demand for the second product. e supply chain is being planned to meet the demand, and the manufactured products are sent from warehouses

Summary

Introduction

Many companies are trying to improve their business processes to meet customer expectations and satisfaction and be able to compete successfully in competitive environments. In this regard, supply chain management is one of the interesting and important issues among academic researchers and industry managers [1]. Ese processes begin with preparing raw materials and end with customer satisfaction by providing final products to customers. Studies show that supply chain management with emphasis on environmental protection has become one of the most critical issues for customers, shareholders, governments, employees, and global pressures
