摘要
并发控制是实时协同设计中的核心技术,本文介绍了一种基于角色的并发控制方法。通过将概念模型按照自然构成的角度进行划分,然后把划分的各层构件映射成某种角色。采用某种策略为角色分配令牌,通过令牌环机制和冲突检测与消解机制实现了单构件设计的冲突避免与多构件设计的并发控制。在此基础上实现了一个同步设计原型系统。
Concurrency control is the kernel technology of synchronized collaborative design, and this paper introduces a method of role - based concurrency control. We split concept model according to the nature component and mapped the splitting component into roles. We assign Tokens to roles according to certain policy, realize collision avoid of single - component design via Token - Ring mechanism and concurrency control of multi - components design via collision detection and resolve mechanism . Based on these we implement one synchronized design prototype system
