| 摘 要： | 在实时计算机支持的协同工作(CSCW)环境中，并发控制是网络协同设计中保持各共享图形、数据实时一致性的关键技术，分析了在CSCW环境下影响操作优先权限的因素，运用模糊数学分析方法计算操作优先权限的分配，提出一种面向对象的实时复制结构下基于优先权限的乐观并发控制协议，并介绍了该协议在协同设计中的具体运用．

| Abstract: | In the environment of real time computer supporting collaborative work (CSCW), concurrency control is one of the keys of maintaining the consistency of graphics and data in the collaborative design. This paper analyzes the properties of the collaborative design on the Internet, presents a prototype system of concurrency control for the collaborative design, analyzes the factors influencing the transaction priority, apply the Fuzzy Mathematics to the priority assignment, develops an priority-based optimistic concurrency control protocol in object-oriented real-time replication structure. Finally, it gives an example to demostrate the application of the protocol in the collaborative design. |
