Abstract :
In this paper, a discrete simulation model of a detergent supply chain has been developed by using Arena Software in order to evaluate and improve inventory system performance. Mentioned supply chain consists of three-echelon, which are: a manufacturer, a central warehouse and four local distributors. All participants use (s, S) inventory control system, a single item has been considered, and also, back order and partial lost sale is allowed in local distributors. According to experts experiences and recommendations, different scenarios have been developed for adjusting inventory control parameters in each echelon. Two categories of financial and operational measures are considered in order to evaluate and improve the supply chain performance. The simulated model clarified complicated aspects of mentioned multi echelon inventory system and helped practitioners to improve their decision makings.
