T he process of project management and its functions are presented. Product design process coordination is also discussed. First, based on the analysis of traditi onal project management, project management and coordination of distributed coop erative product design in the virtual enterprise is put forward. Then, aiming at the characteristics of a distributed concurrent product design process, the inh erent rules and complex interrelations in product development are studied. Accor dingly, the architecture of project management of distributed cooperative produc t design in a virtual enterprise is presented to adapt to distributed concurrent development of complex products. The main advantages of the architecture are al so discussed. Finally, the emphasis is placed on the project management process. Its main functions are set forth, such as project definition, task decompositio n and distribution, resource constraints and dynamic resource scheduling, proces s fusion, task scheduling and monitoring, project plan, cost and quality evaluat ion, etc.展开更多

According to practical application requirements, thetraditional Petri net is expanded and a Rule-restrained Colored Petri Net (RCPN) is put forward tomodel workshop activities. Then, the architecture of the workshop scheduling system based on RCPN ispresented. Finally, the scheduling system that adopts a 3 -layer B/S/D mode is developed on theInternet/Intranet by using the Web database and Java.展开更多
