| Popis: | Vendor-managed inventory (VMI) is an approach to prevent undesired stocking inventories and hence can lead to a cost reduction of the whole supply chain. One of the main objectives of this approach is to optimize the inventory buffer as safety stock and to optimize the scheduling of inventory and delivery. Such optimization could be considered as a problem of the project’s resource scheduling and allocation. In this paper, we present some experimentations for solving this problem by implementing two different algorithms: (i) the Nondominated Sorting Genetic Algorithm (NSGA-II), and (ii) the multi-objective optimization algorithm provided by the MOEA framework. Based on the experimented results, we propose some improvements in using NSGA-II to define an optimized VMI strategy. Such a strategy is implemented and demonstrated through the data collected from a real VMI project. |
