The past two decades, supply chain management focus population science and technology is located. Market globalization, increasing competition, reducing the distance between products in terms of quality and performance, academic environments and industry thinking about this more efficient and effective management operations is forced. Since supply chain management, all companies and organizations that provide an effective product to the customer are integrated into a system looks, reduce costs and increase service levels in providing product and customer service coordination between members is considered . Previous research on supply chain problem focused on the production shipment schedule in terms of the size of order quanities. traortation costs is the most important part of the total operational cost, However, in most joint models, the traortation cost is only considered implicitly as a part of fixed setup or ordering cost and thus is assumed to be independent of the size of the shipmentand. As such, the effect of the traortation cost is not adequately reflected in final planning decisions. Other existing models, the traortation costs as a linear function is considered. The cost function when a discount is considered more consistent with reality, but since the complex structure of the problem will often not considered. In this research we consider a single-manufacturer single-buyer supply chain problem where the manufacturer orders raw materials from its supplier, then using its manufacturing processes converts the raw materials to finished goods, and finally delivers the finished goods to its customer. this chain with Considering traortation cost as a All-unit-discount traortation cost structures with and without over declaration has been studied. policy for dispatch order shipments, equal-size shipment policy. An integrated inventory control model for minimizing the mean total cost per unit time of the raw materials ordering and holding, manufacturer’s setup and finished goods holding, the buyer’s ordering, and inventory holding and cost of traortation of raw material from supplier to manufacture and cost of traortation of finished goods from manufacture to buyer has been studied. Then complete solution of the problem in an explicit and extended manner that has not existed will be introduced. Considering traortation costs to assumptions about the structure and policies of supply chain does not need and can be a wide range of problems on the take. After solving and analysis model to determine the proper amount of order and the optimum amount of total cost is calculated. Keywords: Supply chain, traortation cost, discount
