On BPM Train Operational Scheme Drawing-up Platform

Plan of train's operation is the synthetic plan of railway transportation, whose formulation processes require flex and effective descriptions of demand in all directions to ensure safe and efficient railway transportation. With the great development of railway informatization, application and integration of new equipments and urgency of cooperation of flexible types of work, we need reconstruction and optimization of formulation processes urgent. Nowadays, there is less research on optimization of management of work flow based on SOA at home and abroad was appropriate for plan formulation of train's operation. In this way, research of this paper has high practical significance.The contents of this paper which based on the SOA model of train dispatching system and combined company architecture and work flow directed by thesis of work flow are as follows:First, analyzing and researching on concepts of SOA and work flow, summarizing advantages and modal of relative architectures of BPM based on SOA. Second, analyzing the work flows of processes of plan formulation of train's operation, designing the processes. Third, modeling the existing processes of BPM and verifying rationality of the model, optimizing model based on optimization proposal of work flows to build BPM model based on SOA and verifying rationality of the model. Fourth, the business process is optimized in accordance with the optimization theory. After that, a simulation model and service quality evaluation indexes are constructed by using the tool of Web Sphere Business Modeler. Fifth, expounding advantages of application of BPM based on SOA in formulating plan of train's operation. At last, putting forward directions of farther research.
