摘　　要：作为一类支持人机交互的分布式系统,实时协同设计系统允许多个用户通过网络同步地对同一文档进行编辑。实时性、分布式、用户操作无限制是该系统的三个重要要求,但由于用户的同步操作和网络传输延迟的存在,协同过程中容易产生各种不同步的现象。作为一个实时协同设计原型系统,CoDesign系统实现了相关同步算法。通过对CoDesign系统的分析和实验,模拟了大规模应用中可能遇到的各种不同步的情况。As a kind of distributed system that supports human - computer interaction, real - time collaborative design systems should be highlighted in practical implementation. When we are developing a real- time collaborative system, three requirements of real - time, distribution and unconstraint are to be fulfilled. Because of the concurrent operations from the users and the transmission latency of the network, some concurrent problems take place during the collaborative work. During the cause of the collaborative design, if a site joins the system late, or a site disconnect from the system abnormally and rejoins in, concurrent problems will occur. As a prototype of real - time collaborative system, the CoDesign system implements some algorithms proposed from others. This prototype is tested under the simulation of various situations happen in the cosmically usage of the collaborative system.
