基于有向图的工作流建模及其运行

文章通过定义活动节点、有向边及活动的启动方式构建了基于有向图的工作流模型,利用此模型可以直观地、清晰地表达各种业务工作过程,以解决传统工作流模型在过程表达方面的不足;在此模型的基础上,构建了活动的状态集、状态函数、动作模型和条件模型,给出了活动的执行规则且详细描述了基于该规则的活动内部运行机制;在活动内部运行机制的基础上定义了工作流模型的运行算法。

Study on directed graph based workflow modeling and running of the model

By defining the activity node,the directed edge and the startup mode of activity,the directed graph based workflow model is designed. As all kinds of operation work process are expressed visually and distinctly,the model overcomes the deficiencies of conventional workflow models in process expressing.Moreover,the status set,status function,act model and condition model of activity are built,the executing rule of activity is brought forward,and the inner running mechanism of activity based on the executing rule is introduced in detail.The running arithmetic of the workflow model on the basis of the inner running mechanism of activity is defined.An illustrative example is provided for understanding the implementation procedure.
