On the analyses of each existing concurrent control methods in

the coordination conceptual design,in order to solve the problem of concurrency and

in real-time which could not be taken into account simultaneously in concurrency control mechanism, and the problem of the complexity in the concurrent algorithm development,

the real-time control factor and the safety control factor were used and a concurrent control model was proposed which was based on the high priority of two sections of lock’s. Through the experiments the paper verifies that this model can effectively reduce concurrent conflict in the coordination conceptual design,and proves the security and timeliness of this model.

研究了现有协同概念设计中各种不同的并发控制方法，针对计算机协同工作现有的并发控制机制中实时性和并发度不能同时兼顾、并发算法开发复杂的问题，利用实时控制因子和安全控制因子给出了基于优先截止期两段锁的并发控制模型及算法实现，实验验证了该模型能有效减少协同概念设计时的并发冲突，证明该模型具有很好的安全性和实时性。
