Collaborative Design Conflict Resolution Strategies And Its Application

In existing system of CAD, because of the huge progress obtained in thecomputer graphics in the second half leaf of last century, at the entity design isalready can satisfy the design with the entity shape of demand.But the new technicaldevelopment advance by leaps and bounds, along with the network techniqueespecially the rise of the Internet, they have already changed the mankind's productionand life styles profoundly, to some traditional production life styles of mankind underway exhaustive overthrow,the same at design, we hope to be at any time andanywhere we can design with other members of the group to carry on exchangesinfomations and complete our mission, so cooperative design was put forward.Ourtarget is to get the system with follows characteristics:1. have the ability cooperative in synchronizational or asynchronismal way, andtwo kinds of the way can convert freely.2. the system is open, designer can at any time join and withdraw.3. the system is safe, entering the design of the system and all design operationsare legal.4. the system is strong, it should have the traditional system of CAD to design inthe sketch and the mature technique of the entity shape, should still have the functionof be in cooperative design.The first problem is how to resolve the conflicts in cooperation system , Thispaper have the opinion that there are relations between conflict ,at first give theconflict system in cooperative design,then give a three layers solved project,they aredata layer, the operation layer and the logic layers , the total leading thought of thisbasic solution is to take place the conflict, then according to its the dissimilarity forrelate to solves the method differently for respectively.In the following three chaptersto discuss the layer, the operation layer and the logic layer.The data layer are dividedthree sublayer that was command interface sublayer,model library sublayer and data sublayer ;the operation layer regard design as...
