复制式同步协同设计系统的并发控制研究

Research on Concurrency Control of Replicated Synchronized Collaborative Design System

复制式同步协同设计系统采用平等站点结构,具有高并发特点,为了避免并发冲突,系统采用合理子序列选取法来调整设计者操作序列,放弃冲突操作的方法以达到并发意图一致性,进行快速冲突检测和消解。系统给出了并发冲突的具体判别方法和判断流程图,并发冲突处理具体步骤和处理流程图,设计了并发控制框架,并在此基础上实现了一个复制式的同步协同设计原型系统。

Equal site structure and high concurrency is the charaeteristic of replicated synchronized collaborative design system. To avoid concurrency conflict, the system applies algorithm of selecting with reason children sequence to adjust designer operation sequence, abandon conflict operation to reaeh concurrency intent consistency, quickly detect conflict and resolve it. The system presents the method of distinguishing concurrent conflict and its judging flow chart, and the steps of disposing concurrent conflict and disposing flow chart. Based on the designed framework of concurrency control, a replicated synchronized collaborative design prototype system is implemented.
