协同设计环境下的版本管理模型

Version Management Model in Cooperative Design

计算机支持协同设计（computer supported cooperative design）是计算机支持协同工作CSCW的一个应用领域，也是CAD技术在未来发展的趋势。由于协同设计中多个人员共同参与设计，必然引进约束来保证协同。需要对设计对象和约束进行协调管理。协同设计中设计对象存在着多个版本。如何保证约束和设计对象版本间的一致对于协同设计的顺利进行具有重要意义。针对这些特点，作者提出了一种基于约束的层次化的管理协同设计版本的模型。

： Computer supported cooperative design is one application field of the CSCW，and is the evolution trend of traditional CAD．Because many users participate in the design together，constraints are necessary to assure the cooperation．Managing the design objects and the constraints harmoniously is needed．There are many versions of every design object．It is important to keep the consistency between the constraints and the appropriate design object versions．According to these characters，a hierarchical cooperative design version management model based constraint is presented．
