Abstract�� The hypothesis of reliability model of phased mission systems (PMS) was summed up, and then the shortcoming was also presented that analytical model of PMS is difficult to describe and calculate the complex system, at the same time the simulation model is also hard to be set up. By using the colored Petri net(CPN) Tools, the general model for PMS reliability was set up. The model includes 3 levels: the top control model, which turns the fault trees of PMS into the input parameters of CPN model; the single phase model, whose output is the state of the top event by the input parameters of the top control model; the bottom event model, which produces fault events by comparing rand number to the probability of fault. The general simulation model is robust which can keep the stable model structure for different PMS and the modeling process. The case contrasts the results of the general CPN model with analytical solution, which shows the CPN model is correct and more efficient.
