协同图档流程模型的研究和实践

为更好地处理多流程协同图档操作中存在的问题：复杂的图档文件关系、图档的协同操作及冲突，提出了协同图档流程模型，定义了图档文件集、文件关系和协同图档操作，并通过协同图档文件操作规则和协同图档流程处理来描述协同图档流程管理模式，给出了计算文件操作冲突集的方法，并提供了冲突解决规则及算法.结果表明，协同图档流程模型能很好地解决了多流程下对复杂关系图档集合的协同操作，能充分发挥三维CAD协同设计能力.

Research and application of collaborative document workflow model

In order to solve the problems in multi-workflow collaborative document operation such as complicated document relationship,document collaborative operation and conflict,this paper propose a collaborative document workflow model(CDWFM) by defining documents set,document relationship and collaborative document operations.A collaborative document workflow administrative pattern was also described by establishing collaborative document operation rules and collaborative document workflow process,where the algorithm of conflicts set was given and conflict resolution rules and algorithm was provided.The results show that CDWFM can solve the problems which exist in the collaborative operation of complicated relationship document set in the case of multi-workflow,and improve the efficiency of collaborative design of 3D CAD.
