WfMS系统建模和内部协调

System Modeling and Internal Coordination Against WfMS

通过对工作流和工作流管理系统相关定义和功能的分析，建立了基于关系和模型分解的工作流和工作流管理系统的数学模型。根据建立的参考模型，针对工作流管理系统的协调重点，从任务序列的执行和模型对象的扩展两个方面，对工作流管理系统提出两种协调模式，并对协调方式的机理和内容进行了研究。为了满足系统扩展的需要，本文还对工作流管理系统的开放性进行了探讨。

In this paper, according to the analysis of the Workflow and Workflow Management System's functions and their related definitions, the Workflow and Workflow Management System's mathematical models are proposed based on relation and model's decomposition. With the model presented the authors put forward two kinds of concerted coordinating patterns against the Workflow Management System's coordinating emphasis following the task sequence and model objects' expansion, and explore the mechanism and content of coordination. In order to meet the system's expansive requirements, the openness of Workflow Management System is discussed at last.
