Designing a Medical Supply Chain Network Considering the Risk of Supply and Flexible Production in Two-Stage Uncertain Conditions

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.

Exploring the Application and Optimization Strategy of the LMBP Algorithm in Supply Chain Performance Evaluation

“…Enterprises can use the Internet and big data technology to closely link enterprises and consumers so that consumer demand data and information can be quickly communicated to producers and brand owners [27][28][29][30]. It can also organize material procurement, manufacturing, and material distribution according to changes in market demand so that the production mode can be changed from high-volume, standardpush production to market demand-pull production and closely coordinate the business processes of the supply chain to achieve more flexible management [31][32][33][34][35][36][37][38][39]. At the same time, it should also focus on the digitalization of product information, standardization of process technology, and multifaceted skills of production staff to improve the overall flexibility of the supply chain.…”
