Stochastic production routing problem for perishable products: Modeling and a solution algorithm

The freshness of perishable products, in addition to other economic aspects such as production, inventory, and transportation management, is one the main challenges food supply chains. Therefore, integration routing decisions essential. In this study, a new production model for products with uncertain demand presented. aim minimize costs routing, wasted penalties non-fresh products. more applicable limited, discrete shelf life high value. A five-phase matheuristic algorithm proposed solve stochastic mathematical model. Computational experiments show that can result significant reduction particularly when consumer buying patterns change due various occurrences, pandemic. Also, numerical analysis small, medium, large instances confirms validity efficiency compared an exact solver. • Proposing two-stage programming problem Considering wastage Development five phases considered problem. Performing computational on pandemic normal situation instances.
