工作流管理技术是 90年代初新兴起的软件技术。其实现的关键在于工作流概念模型的建立。虽然信息系统领域的建模理论已经发展得较为成熟 ,但在工作流管理领域还没有一个专门的建模工具来满足工作流建模的需求。通过对几种概念建模方法的比较分析 ,论文选择 Petri网作为工作流建模的主要工具 ,并探讨和总结了工作流程的路由结构、触发机制、可靠性工作流模型的分析方法 ,转换原则和组合性质 ,最后通过一个案例进一步阐述了基于 Petri网的工作流建模技术。实际应用表明该建模方法简单、可行 ,能够保证工作流模型的有效性 ,而且便于工作流网络的计算机形式化表示 ,有利于工作流管理系统 (WFMS)的实现。
Workflow management technology is the emerging software technology in the early 90s. The key to its realization lies in the establishment of a workflow conceptual model. Although modeling theory in the field of information systems has matured, there is no specific modeling tool in the field of workflow management to meet the needs of workflow modeling. Through comparative analysis of several conceptual modeling methods, the paper chooses Petri net as the main tool of workflow modeling, and discusses and summarizes the workflow structure, triggering mechanism, reliability workflow model analysis method, conversion principle And the nature of the combination. Finally, through a case further elaborated Petri net-based workflow modeling technology. The practical application shows that the modeling method is simple and feasible, which can ensure the validity of the workflow model and facilitate the formal representation of the computer in the workflow network, which is beneficial to the realization of the workflow management system (WFMS).
