摘要
过程集成是ＣＩＭＳ信息技术发展的新方向，工作流技术是实现过程集成的关键技术之一。采用分布对象技术可以解决工作流执行系统实现中的异构分布处理、应用系统接口等问题，并有助于系统组件重用。本文讨论了基于分布对象技术ＣＯＲＢＡ的工作流执行系统的设计，分析了以对象请求代理（ＯＲＢ）为主要底层支撑的系统功能结构，研究了系统设计中模型语义支持与分布粒度等技术。
Process integration is becoming more important in CIMS technology, and workflow management is a key tool for process integration in information systems. The distributed object-oriented technology can provide feasible solution to workflow execution system implementation. It can solve such problems as heterogeneous distributed processing and the intefacing with application systems. It is also useful to system components reuse. In this paper several issues in workflow executing system developing in a CORBA/ORB based distributed environments are discussed, including the system architecture, the semantics for workflow modeling, the distribution granularity of control objects. A system design is presented for illustration.
