一种扩展的工作流过程定义模型

Extended Workflow Process Defintion Model

提出了一个支持复杂应用的扩展工作流过程定义模型Scope PModel,它可以描述复杂结构的工作流流程,并且能够清晰地描述任务之间的控制流依赖关系和任务的补偿信息,表达出复杂工作流程的定义;同时,本文所提出的工作流过程定义模型Scope PModel,不仅可以捕捉现实世界业务流程,具有丰富的表达能力,使工作流定义的语义更为明确,而且为工作流过程定义模型验证提供了强大、丰富的理论依据,为工作流过程定义模型验证奠定了良好基础.Scope Work是我们自行研制开发的工作流管理系统的原型系统,它基于该模型实现了复杂业务过程的工作流过程定义以及调度等功能.

Discussed ScopePModel that is an extended workflow process definition model for complex applications. The ScopePModel can describe complex workflow process, mutual relation of control stream and compensation information of task. The model not only has abundant expression ability for business process of real world and can make the semantic of workflow definition more definitely, but also provides powerful and abundant theory elements for the verification of workflow process model. The ScopeWork, our prototype WfMS, is based on the ScopePModel, so that it can accomplish workflow process definition of complex business process and enactment services.
