CSCW环境下协同设计并发控制算法的研究

Research on the Algorithm of Cooperative Design Concurrent Control in CSCW Environment

并发控制是CSCW环境下协同设计中复杂而又关键的问题之一,分析几何信息模型对象特征之间的联系,建立特征之间的相交和约束关系。运用模糊数学分析方法,提出一种优先权限分配算法,给出版本管理的解决方案。设计和实现针对共享对象协同操作的一致性维护和并发控制算法,并通过实例验证算法有效性。

The concurrent control is one of the complex and key issues for cooperative design in CSCW environment, analyzes the relationship of the features between geometric information model object, establishes the intersection and constraint relationship between characteristics. Puts forward an algorithm of priority privilege＆#39;s assigning by using fuzzy mathematics analysis method, and gives the solution of version man-agement. Designs and implements the consistency maintenance and concurrency control algorithm aiming at cooperative operation of shar-ing objects,and verifies the effectiveness of the algorithm.
