基于元图的工作流建模分析方法

工作流可以有效的规范业务流程、监控流程的执行，而且能够根据客户的需求创建出新流程模型。工作流的建模过程存在一定的复杂性，它要求创建的新模型具有可视化和可操作的特点，同时模型的有效性（即正确性与合理性）也是相当重要的。将元图运用于工作流建模和分析过程，以具体的业务流程为背景，逐步分析隐含在流程中的深层次问题，找出信息元素、活动和资源之间的相互关系，从而确保工作流模型的有效性。

Workflow Modeling Analysis Using a Metagraph Based Approach

The business process can be formalized effectively and its implementation will be controlled by workflow;besides,a process model can be re-produced by the new requirements.The process of workflow modeling is rather complex.On one hand,the new model should owns the characteristics of the visualization and the operation.On the other hand,the validity(correctness and rationality)of the model is considerably important.In this paper,the metagraphs has been used into the process of workflow modeling and analysis.Concrete examples of business process will be applied and some abstruse problems contained in these process will be analyzed step by step.In the end,the relationship among the information elements,activities and resources will be discovered,therefore,this analysis process can assure the validity of the workflow models.
