A Study On Joint Managed Inventory Of DL Iron & Steel Company Based On Supply-Chain

Since 1990s,with the application of various kinds of high and new technology in iron and steel enterprises, how to increase productivity and reduce production cost is considered more and more important. Since long ago more attention has been paid by the enterprises to production process optimization of the steel product itself when they consider reducing costs. At present this way of reducing cost does not mean much any longer. The traditional sense that inventory is idle resources or temporary reserves, the paper stock that is not only for the true nature of materials and logistics management, and also including the entire business process workflow management. For the joint inventory management strategy, a large number of researchers started from the focal point of finished products for distribution during the study; this paper to DL-based steel company, from raw materials occupy 70% of business start reaching out to the focal point of raw materials, research DL-based inventory management co-sourcing logistics management company.In this dissertation the author analyzes thoroughly the four big problems existing in the original fuel supply chain management of DL Company:long purchasing lead time, large inventory, instable origial fuel supply and suppliers changing frequently and low partners'loyalty index and information sharing degree. The research proves that the implementation of the supply chain management method of JMI can effectively solve above-mentioned problems existing in DL Steel Company. By analyzing the inventory cost structure by establishing a mathematical model, it proves from the view of mathematics that the implementation of JMI can effectively reduce the inventory cost of DL Company. The author Puts forward four specific ways of implementing JMI:to establish cooperation relations with suppliers by contacts; to realize information sharing by creating a technology platform; to closely cooperate with stable third party logistics; to establish interest coordination mechanism. Then, according to the goal and principle of evaluation and the characteristics of the steel industry, the author sets up, from the four dimensions of logistics performance, financial performance, informationization level and relationship management ability, an index system which includes four one class indexes and eighteen level 2 indexes. The index system embodies the four great combinations, namely, the combination of logistics, cash flow, information flow and business flow, the combination of short-term interests and long-term interests, the combination of financial index and nonfinancial index and the combination of internal performance and external performance.The weight coefficients of the indexes are determined by using analytic hierarchy process; first-hand data are obtained by sending questionnaires to the management from every department; then the comprehensive evaluation is conducted by using the fuzzy evaluation method. Finally the conclusion is drawn that the performance level after the implementation of JMI will be far higher than the present supply chain performance level of DL Company.
