The Management System Of Spare Parts Based On The Modeling Technology Of The Finite-State Machine

Nowadays, it has becoming more and more important for the telecommunications equipment manufactures to maintain its superior position in the fierce competition. The cost and quality of the device, and also the efficiency of the maintenance have effect the competitiveness of the enterprise. As the above reasons, the importance of the management system of the spare parts is increasing. Therefore, it's reasonable for the enterprises to build up a management system of the spare parts.Considering the enterprise's business processes, combined with its past experience and working model, the paper proposes a comprehensive solution based on the modeling technology of the finite-state machine.The finite state machine describes the limited state and the transfer between these states. It's quite easy to describe the business service and the model of the system. The main work of paper could be described as follows:(1) Describe the business service of the spare parts, and expound the demands of the system. Then build up the model based on the finite-state machine and the command pattern suggested by GOF.(2) Analysis the basic function of the spare parts system, then develop into several models such as the applytable management and the dispatchtable management and so on. In the last introduce the basic technology of the system.(3) Design and implement the models of the spare parts management system. At last, describe the security of the system.
