基于对象的角色工作流模型研究

工作流是流程集成的有效方法，但工作流模型在描述复杂的流程时语义和柔性不足，导致实用中工作流模型的仿真分析和运行能力欠佳；另一方面，对象技术作为一种很有潜力的流程建模方法，可以改善工作流的描述。它与工作流的结合，将有助于上述问题的解决。文章借助对象技术，分析了面向角色的工作流模型，并在此基础上讨论了其实现。

Study of Object-oriented Role Workflow Models

Workflow management systems lay foundations for process integration. But semantics and flexibility of workflow models seem to be inefficient when describing complex workflows, which lead to low simulation analysis capability. On the other hand, object-oriented technology can be used to describe complex processes as a perspective workflow modeling method. In view of the methodology, workflow modeling and object-oriented technology complement each other. The combination of them provides a way-out for integrating workflow modeling, analysis and implementation effectively. Using OT, this paper analyses the application of object-oriented technology role workflow models, and discusses its implementation.
