- Abstract:
- This paper proposes a collaborative design model based on operation semantics in a distributed computer-aided design(CAD)environment. The goal is to reduce time consumption in data format conversion and the requirement of network bandwidth so as to improve the cooperative ability and the synchronization efficiency. Firstly, real-time collaborative design is reviewed and three kinds of real-time collaborative design models are discussed. Secondly, the concept of operation semantics is defined and the framework of an operation semantics model is presented. The operation semantics carries the original design data and actual operation process to express design intent and operation activity in conventional CAD systems. Finally, according to the operation semantics model, a CAD operation primitive is defined which can be retrieved from and mapped to the local CAD system operation commands; a distributed CAD collaborative architecture based on the model is presented, and an example is given to verify the model.
- 提出了一种应用于分布式CAD环境中的基于操作语义的协同设计模型. 主要目的是为了减少数据转换的耗时量以及降低对网络带宽的需求, 从而改善协作能力, 提高实时同步的效果. 首先回顾了实时协同设计的发展现状, 讨论了3种实时协同设计模型. 其次, 给出了操作语义的定义, 并提出了一个操作语义模型框架. 操作语义包含原始设计数据和实际操作过程, 表达CAD系统中的设计者意图和操作活动. 最后, 根据操作语义模型, 定义了CAD操作原语, 该原语可以从CAD操作中提取也可以映射成CAD操作命令; 给出了一种基于该模型的分布CAD协同体系结构, 并通过一个实例加以验证.
