摘要
通过对工作流模型过程定义的分析 ,利用不同的模型机制聚合工作流建模涉及的要素 ,认为工作流模型是一个基于信息模型、功能模型、组织模型和资源模型的复合模型 ,探讨了模型之间的逻辑关系 ,以及基于复合建模原理的建模步骤。在针对面向过程开展的资源配置研究的基础上 ,借助敏捷制造过程的应用实例 ,分析了基于Petri网的复合工作流模型的建模步骤。根据分层和分块原则 ,对基于Petri网的复杂工作流模型的简化提出了一种分解策略 。
By analyzing the process's definition in workflow modeling, the factors resolved in modeling are polymerized with different model, and the global model of workflow system is considered as the combined model of the information model, function model, organization model and resource model. The logical relationship among these models is explored and the steps of hierarchical modeling are discussed in theory. The detailed approaches for hierarchical modeling are put forward,which is illustrated by an instance of agile manufacturing. For simplified representation of the complex workflow's model, a strategy of decomposition is proposed based on the hierarchical and blocking method and how to make use of this method is demonstrated.
