At this point, using of the right inventory control policy is the most effective andefficient way to reduce shortage. In inventory control policies, the basic question is to specify the size and thetiming of a replenishment order in supply chain members. Over the years, many advanced methods have beenapplied to answer these questions. Due to the difficulty of dealing with the uncertainties in supply chainenvironment, simulation optimization (SO) is used in this study to get the application of goals in supply chain.Although SO requires a great deal of understanding related with inventory control system, the use of SObrings such complex system within the grasp of managers. In this paper, SO is used to analyze the supplierselection and inventory control system simultaneously. The system results clearly reveals that the best valuesof inventory control variables and the most suitable suppliers can be determined by SO in a two echelonsupply chain model with backorder.eninfo:eu-repo/semantics/openAccessArticle212120038461629
