Abstract: An extended Time Petri Net with condition information (ECTPN) is presented in this paper including two new attributes associated to place and transition that respectively represent input condition set and output condition set. Using the model can achieve multitask cooperation and competition and let token be able to select next transaction path according to inner information. Firstly, the Time Petri Net is introduced, and then a formal semantic meaning for ECTPN in terms of input and output items is defined. Finally, we give the denotation of ECTPN. Application shows that the ECTPN validate by using business modeling.

Abstract: Process modeling of Cooperative Product Development (CPD) is the key of CPD process management. Analyzing the process of developing production based upon Petri Nets, referring to workflow management and combining with parallel project, a new workflow modeling method based upon layered timed color Petri nets is invented, which supports the developing of the model production that parallels CAD/CAPP. Finally taking the developing CDP of model product as an example, workflow model has been designed and has been inspected and verified in the software platform.
