A vendor-managed inventory model based on optimal retailers selection and reliability of supply chain

One of the most common and successful approaches for integrated supply chain management (SCM) is vendor-managed inventory (VMI). In VMI, a vendor takes control decisions retailers. To establish long-run relationship between retailer, it necessary to consider two impactful factors: vendors retailers' reliability, optimal selection For this purpose, redundancy allocation problem (RAP), as an effective technique increasing reliability vendors, used in paper. Also, retailers well are considered. retailer selection, process on criteria simultaneously one analysis hierarchical (AHP) performed each vendor, weights obtained. Then, obtained plugged into model inputs designed model. Since developed non-differentiable, non-convex, mixed-integer function, genetic algorithm (GA) particle swarm optimization (PSO) leveraged solve formulated Finally, efficiency presented method verified through case study with data collected from electronic chain.
