| Abstract: | Analyzing and optimizing of cooperative model is key technology to improve cooperative work efficiency, that can be applied widely in the engineering field of computer supported cooperative design etc. Based on comparability theory and Petri net, fuzzy-timing relation of collaborative activities events is analyzed, and a method is discussed to model collaborative design course. Data structure of model element is described using Object-Orient method, and a simulation algorithm is given. At last the former modeling and simulation algorithm are proveed to improve describing ability for collaborative design course, temporal reasoning and analyzing quantitatively are accomplished for collaborative design performance. |
