As the industrial environment becomes more competitive, supply chain management has become essential. The objective of this research is to develop a multi-echelon inventory model for a deteriorating item and to derive an optimal joint total cost. Inventory models for the manufacturer and the retailer were developed when deteriorating rates were constant, and demand rate of customer decreased linearly with time and depended on retailers’ current inventory level. The objective was to develop an optimal ordering strategy for retailers to minimize the average total cost of this inventory system. This paper establishes an inventory model of manufacturers and retailers, and gives the optimal production time algorithm. Then, we will carry out simulation test for example. We calculate the system of minimum average total cost that respectively from producers, retailers and integration. Thus, it confirms that the average total cost which from the supply chain integration is lower than from the manufacturer or retailer alone.
