摘要
本文提出了一个分布式三维CAD(Computer Aided Design)协同设计环境中进行冲突避免、检测和解决的模型DCCM(Distributed Cooperation Conflicts Model).DCCM将具有语义的CAD命令分为两类,混合使用操作序列化和半乐观锁机制进行并发控制;提供协同感知机制避免协作冲突;采用两级冲突解决模式,基于命令的语义进行冲突检测,提供仲裁者机制协商解决冲突.
This paper presents a model named DCCM (Distributed Cooperation Conflicts Model) for conflicts avoiding,detecting and solving for 3-D distributed CAD cooperative design. DCCM classified semantic CAD operations into two types, mixed operation serialization and semi-optimize locking for concurrency control, afforded cooperative awareness to avoid conflicts, used 2- level conflict solving system, detected conflicts based on operations' semantics, afforded interceder based consulting policy for confilets solving.
