| Abstract: | The performance evaluation is an important aspect in analysis and evaluation of workflow models. Firstly, the general Petri net models for business procedures are presented and then the time Petri net is introduced to establish time constraint model of workflow nets. The net transformation rules keeping time constraint and the method for time performance calculating are proposed to simplify workflow net and calculate performance, and corresponding algorithm is provided. Finally, the applying procedure of this method is demonstrated by an example. |
