摘　　要：针对目前复制式协同特征型系统大都采用并发冲突防止策略的锁机制,使得协同系统的并发度受到很大影响的现状,通过对特征造型过程中并发冲突的分析,提出一种非锁的基于特征依赖关系的并发控制机制,提高了协同设计的并发度,最后采用C++编程语言结合WinSocket技术建立一个实现该并法控制机制的协同特征造型系统.Currently, most replicated collaborative feature modeling systems use locked mechanism to prevent conflicts and the degree of parallelism of collaborative system is limited. Based on the analysis of concurrency conflicts of feature modeling activities, a non-locked and based on feature dependency concurrency control mechanism is proposed. It improves the degree of collaborative design. The concurrency mechanism has been implemented in a collaborative feature modeling system integrating C ＋ ＋ and WinSoeket technologies.
