Abstract

The outbreak of the deadly coronavirus, which is increasing the number of victims every day, has created many changes in today’s world. The use of various masks is the most important social tool against this virus. Given the importance of rapid and quality supply of masks in the current situation, it is necessary to study supply chain in particular. In this research, the design of a closed chain supply chain network for different types of masks is assessed. The studied supply chain includes suppliers, manufacturers, distributors, and retailers in the forward flow and collection centers, separate centers, recycling centers, and disposal centers in the backward flow. In this regard, a multi-objective mathematical model with the objectives of increasing the total profit and reducing the total environmental impact, and maximizing social responsibility is presented. The optimization of this mathematical model has been done using a fuzzy optimization approach in GAMS software. The results of this study show that maximizing the total profit and minimizing the environmental effects and maximizing social responsibility are in contrast to each other. In addition, the sensitivity analysis indicated that the customers’ demand can affect all aspects of the sustainable supply chain simultaneously.

IntroductionIn today’s competitive market, production and economic agencies have felt the need for the management and supervision of resources and related pillars outside the organization in addition to dealing with internal resources
The overall structure of the sustainable closed-loop mask supply chain is presented in overall the sustainable mask chain is presented
A multi-objecmathematical model is presented to design a closed-loop mask supply chain, the first and tive mathematical presented to design a closed-loop mask supply chain, first second objectives ofmodel whichisare to increase the total profit of the supply chain andthe decrease and second objectives of which are to increase the total profit of the supply chain and of unfavorable environmental effects, respectively

Summary

Introduction

In today’s competitive market, production and economic agencies have felt the need for the management and supervision of resources and related pillars outside the organization in addition to dealing with internal resources This is mainly carried out to achieve a competitive advantage and earn a larger share of the market while considering environmental issues. Activities such as supply and demand planning, material production, product planning and production, product maintenance services, inventory control, distribution, delivery, and service to customers, which were all performed at the company level in the past, are included at the supply chain level. The key issue in a supply chain is the management and coordinated control of all activities
