基于图结构的工作流技术分析和研究

通过对工作流基本组成元素和工作流动作特点的分析，利用工作流开展的时间差和人力资源的复用性，从并行工程的角度出发，提出了一种基于产品逻辑结构的柔性工作流思想，根据这一思想，结合产品形成过程的逻辑关系，利用有关图论的知识，构造了一个基于全息树结构的柔性工作流模型，实现了逻辑信息、工作流程的有机融合，同时也给出了支持这种柔性工作流模型的后台关系数据库结构。

Analysis and Study of Workflow Based on Graph Construct

In this paper, the authors plotted out the basic units of workflow and analyzed their operational features. By making use of the delay among the processes of workflow and the reuse of manpower resource, a thinking of flexible Workflow was presented based on the product logical structure from the view point of concurrent engineering. According to this idea and knowledge of graph theory, a model of flexible Workflow based on the holographic tree structure was constructed to show the logical relationships in the process of product development. By this way the logical information and the process of Workflow were united organically. The authors also give the architecture of relational database supporting this flexible Workflow model.
