Abstract: The equipment maintenance management is an essential subsystem of the EMU maintenance management system. It ensures the effective and safety operation of the maintenance works. With the wider and deeper application of the equipment maintenance management system, simple work system can no longer meet the demands for mutifunction, mutibussiness and mutisystem, and it is rather important to design good web services to complete the business process and provide support of theequipment maintenance management. The paper analyzes the features of the BPEL language specification. The business process integration based on the BPEL of EMU maintenance equipment management are discussed. With the actual business process of EMU maintenance equipment, the design and implementation are presented. It improves the flexibility of EMU maintenance equipment maintenance management.

摘要： 动车组管理信息系统设备管理子系统是动车组管理信息系统的重要组成部分，为检修现场的业务高效安全开展提供重要的保障.随着动车组管理信息系统设备管理子系统现场应用的不断深入，在现场应用中,经常出现跨职能、跨业务甚至跨系统之间的业务流程.简单的Web服务调用已经不能够满足业务变更的需要，如何能够灵活地组织和编排相关的Web服务来完成业务流程，为动车组高效检修提供服务支持成为设备管理的重要问题.本文使用BPEL规范，对动车组检修设备管理的业务流程集成进行了讨论，结合动车组检修设备实际业务流程给出了设计与实现，实现了动车组检修设备管理的业务集成及灵活组织.
