%X Now an enterprise attaches great importance not only to system performance but also to system cost. In view of this situation the price stochastic Petri net was put forward in order to analyse the system price and performance. On one hand, price stochastic Petri net possesses the advantage of perfommnce analysis like stochastic Petri net. On the other hand, it can calculate system cost and guide the establishment, improvement of system macroly. An equivalent simplified method of collaborative services typical model based on price Stochastic Petri net was put forward. And corresponding certification was done. This method can improve the system analysis efficiency to a certain extent.
