Therefore, how to control the logistics costs under the existing condition is the urgent problem for the iron and steel enterprises. In recent years, many researchers have conducted studies on Logistics Cost Management. For cost control of iron and steel enterprises, these studies mainly took the viewpoint of production logistics and production techniques. As present, the logistics cost control of small and mediumsized iron and steel enterprises mainly have the following major problems: In order to prevent interruption of the supply of raw materials, the enterprises overstock raw material and work in inventory of raw materials, semifinished products, and purchased ponents is determined according to stock requirement, rather than driven by the orders decades of development, production logistics situation has bee more plicated. It has brought more and more challenges to the daytoday business operation and planning of the enterprises. We assume that the production capacity of enterprises can fully meet the needs of the market。 Theoretically speaking， although its precision has certain error； pared to the traditional location method depending on subjective imagination． it is scientific somewhat． Additionally, the abovementioned method is concise， and no advanced puter programming technology is needed， as long as with certain puter knowledge and operating skills， anyone can plete it， and easily apply it to logistics practice． Experiences from abroad shows that the correct location of agricultural product logistics distribution center will help the healthy and Orderly development of logistics industry． The rapid industrialization and growth of many countries around the world has spurred the development of supply chains management reach around the world. Supply chain management is the management which increases the value of supply chain. It is the process of plan, moderateness and control among departments and anizations in the whole supply chain to the flow of goods, information and capital etc. Its purpose is to maximize value and increase operational efficiency and effectiveness to all related process through system optimization. Supply chain management is the high stage of logistics development, which provide opportunities for manufacturers to cut costs and be closer to emerging and 北京化工大學北方學院畢業(yè)設計（論文） —— 外文文獻原稿和譯文 4 high growth markets but it has also created new risks. As supply chains bee more and more dependent on the efficient of logistics center in supply chain have great influence to the modern logistics. It play an important role in making use of logistic resources, upgradin
