A Study On The Equipment Spare Parts Management Based On The Supply-Chain Coordination

The spare parts management is an essential content in a business device management work. It is directly influence equipment's maintenance, the overhaul, the rush repair work, which are closely related with enterprise's regular production and the economic benefits. On the premise of production needs, enterprise should reduce the cost of spare parts and the reserve fund of them as far as possible. Since the spare parts demand regularity is poor and random, it is hard to forecast precisely. Along with the rapid development of science and technology and the unceasingly application of new technical achievement in the equipment, modern equipment was oriented to the direction of maximization, high-speed, flow process, precise treatment, computerization, flexibility and intellectualization, at the same time some of the equipment's certain essential spare parts are becoming more and more accurate, complex and expensive. In order to replace the destroyed spare parts promptly and reduce the loss of shutdown, the spare parts JIT supply becomes an important subject in the area of device management. This paper is research on equipment spare parts coordination management pattern based on modern supply chain management theory.Beginning with the angle of enterprise spare parts management, this paper propose to establish the spare parts coordination management system between the spare parts supplier and the user, and unify the Internet and the information system to build the information integration and exchange platform of enterprise and the supply chain, which could realize the breakdown prediction and the coordination control of spare parts supply. The analysis is carried on to the equipment spare parts' demand forecast method. Understanding the spare parts' historical breakage data, this paper use the Bayesian theorem to forecast the spare parts' demand in future time section.Considering the numerous nodes on the supply chain of equipment spare parts, this paper proposes the use of coordination, forecasting and the stock management pattern of supply. Under the constraint of the order point level for the service and the stock, this paper obtains the spare parts supply strategy which satisfied the smallest system total cost and the assigned service level through the establishment of stock optimization model and the solution. It is better to use the supply chain information platform for the supplier management. The application case indicates that the spare parts management has the very good application prospect based on the chain coordinates.
