Design and application of workflow modeling based on extended-directed graph
基于扩展有向图的工作流建模的设计与应用

According to the analysis of the object of the workflow modeling, a workflow modeling based on extended-directed graph was proposed in this paper, and this model from node, directed acyclic and evolutionary rules were analyzed. Based on these, a workflow visual modeling was given. The effectiveness of this model in practice was illuminated through a concrete example. It is a brand new solution proposed to settle the key problems in the traditional modeling software development.
