Abstract

The complex and changeable external social and economic environment has a significant impact on the sustainable development of the closed-loop supply chain In particular, the occurrence of uncertain emergencies increases the risk of interruption of the closed-loop supply chain, making it insufficient to analyze its complex changes from the perspective of material flow alone Based on this analysis, the paper constructs a closed-loop supply chain material flow and capital flow coupling system composed of manufacturers, sellers and recyclers to explore the impact of material flow sudden interruption on the closed-loop supply chain system when an uncertain emergency occurs In this paper, based on the closed-loop supply chain system coupled with logistics and capital flow, a system dynamics simulation model was established by using Vensim simulation software to analyze the impact of COVID-19 epidemic on manufacturers, sellers and recyclers under five scenarios The results show that when COVID-19 outbreaks occur, the material flow of each main enterprise in the closed-loop supply chain is more easily influenced than the capital flow At the same time, it can be found that the recyclers in the main enterprises of the closed-loop supply chain are more easily influenced by the material flow The model constructed in this paper has applicability and can be used for related studies of closed-loop supply chain under other emergencies, but the scene design should be carried out according to the characteristics of emergencies themselves © 2021 Production Engineering Institute All rights reserved

新冠肺炎疫情对闭环供应链物流和资金流耦合的影响分析

复杂多变的外部社会经济环境对闭环供应链的可持续发展产生重大影响，特别是不确定突发事件的发生，增加了闭环供应链中断的风险，仅从物料流的角度分析其复杂变化是不够的。本文构建了一个由制造商、销售商和回收商组成的闭环供应链物料流和资金流耦合系统，探讨在不确定突发事件发生时，物料流突然中断对闭环供应链系统的影响。本文基于物流和资金流耦合的闭环供应链系统，利用Vensim仿真软件建立系统动力学仿真模型，分析了五种情况下新冠肺炎疫情对制造商、销售商和回收商的影响。结果表明，当新冠肺炎疫情发生时，闭环供应链中各主要企业的物资流比资金流更容易受到影响。可以发现，闭环供应链主体企业中的回收者更容易受到物料流的影响。本文构建的模型具有适用性，可用于其他突发事件下闭环供应链的相关研究，但需根据突发事件本身的特点进行场景设计©2021生产工程研究院版权所有

期刊介绍： Advances in Production Engineering & Management (APEM journal) is an interdisciplinary international academic journal published quarterly. The main goal of the APEM journal is to present original, high quality, theoretical and application-oriented research developments in all areas of production engineering and production management to a broad audience of academics and practitioners. In order to bridge the gap between theory and practice, applications based on advanced theory and case studies are particularly welcome. For theoretical papers, their originality and research contributions are the main factors in the evaluation process. General approaches, formalisms, algorithms or techniques should be illustrated with significant applications that demonstrate their applicability to real-world problems. Please note the APEM journal is not intended especially for studying problems in the finance, economics, business, and bank sectors even though the methodology in the paper is quality/project management oriented. Therefore, the papers should include a substantial level of engineering issues in the field of manufacturing engineering.
