Vendor-managed inventory (VMI) policies within integrated supply chain management (SCM) represent a robust approach that effectively addresses demand, quality, and inventory management, encompassing the sharing of information and data between vendors and retailers. However, in the context of perishable products, timely inventory management becomes crucial, as its success hinges significantly on product quality, which is an area that has been relatively unexplored in the VMI literature. One emerging and efficient method to tackle VMI for perishable products is the deployment of Internet of Things (IoT) devices throughout the entire supply chain. These devices enable real-time tracking and tracing of product quality, encompassing manufacturing processes. Consequently, this study aims to develop a model for selecting the most suitable IoT devices for managing perishable products in supply chains. Despite its significance, the problem of retailer selection based on critical criteria in VMI has not been thoroughly investigated to date. This paper offers optimal policies to enhance production planning and minimize waste for suppliers by harnessing the advantages of VMI and IoT. To validate the proposed model, a case study involving real data from the food supply chain is examined.
