1、燕山大学博士学位论文产品异地协同设计模式和支撑环境研究姓名：黄国言申请学位级别：博士专业：机械电子工程指导教师：孙惠学20060901燕山大学T=学博十学何论文的解决了CSCW工作环境下的不同传输媒体协议栈之间的协调问题。并在此基础上给出了视频系统的设计方法，该系统可以嵌入协同设计环境，感知协同环境的变化。最后，将时序推理、模糊理论和Petri网技术结合起来，按工作流概念对协同设计过程建模，在此基础上，给出了协作设计活动中模糊、不确定时间的定义，引入了协作设计活动事件间的模糊关系，并且利用模糊变换原理建立相应的评估和推理机制，实现对协同设计过程模型的时间和成本等的

2、性能分析，从而解决了对协同设计方案的定量与定性评价。从而为优化协同设计方案提供理论依据。关键词计算机支持的协同工作；协同设计；CAD：应用共享；访问控制；并发控制；群组通信；Petri网ⅡAbstractProductisthelifeofenterpriseandnewproductdevelopmentistheimpetusofenterpriseevolution．Theproductdevelopingprocessisnotonlycreativeandintelligent，butalsocollectiveandcooperative．Produc
