Most manufacturing firms have focused on managing efficiently their supply chains that purchasing raw materials, producing final products, and supplying them to retailers. Since a supply chain network is composed of several stages and components, a little variation of retail sales may result in significant changes for each component on supply chains. In this view, a manufacturer is expected both to synchronize its products with the retailer’s demand and to coordinate the ordering of raw materials with production processes so that both raw materials and final goods inventories are reduced. This paper addresses an integration of SCM and RM problems in manufacturing systems－specifically, the simultaneous determination of procurement of raw materials, production plan and supply policy for each customer in the circumstance of demand uncertainty. We focus on modeling our problem as a stochastic dynamic programming model and extensive computational results with randomly generated problems are reported.
