| 摘 要： | 介绍了工作流的概念及发展过程,讨论工作流建模的基本方法。重点分析Petri网和UM L在工作流模型设计过程中的应用,结合Petri网语义定义工具和图形化界面以及UM L的面向对象特点,形成基于Petri网和UM L的工作流建模方法。工作流模型的语义定义采用Petri网表达,给出工作流网的形式化描述。工作流系统的设计模型采用UM L进行定义,对于业务逻辑、执行过程、数据结构分别采用用户实例图、顺序图、类图进行描述。在工作流的实现上,采用软组件实现工作流服务组件的分布布置,并通过接口定义语言对功能组件中的服务进行发布。最后给出工作流的发展趋势,并计划开展工作流仿真和优化方面的研究。

| Abstract: | The concept and development periods of the workflow are introduced firstly, and the method for the workflow modeling is discussed.In the semantic definition,Petri net has advantages of strict mathematical express and the graphic interface.In the design and implementation,the unified model language(UML) provides object-oriented methods.Combined Petri net with UML,the logical layer of the workflow system is defined by Petri net,and the physical model is described by UML.Based on the standard Petri net the workflow net is defined.Business process, execute route and data structure are described by using case diagraph,sequence diagraph and class diagraph of UML.Finally,the implementation of the workflow is discussed.Function components are encapsulated in the distributed component object model(DCOM),and interfaces are displayed in interface definition language(IDL). |
