Abstract: Concerning the problem of system reliability assessment for complicated electronic equipment under the zero-failure data, this paper proposed a method of simulation assessment based on circuit units performance. Firstly all circuit function units in the system were fixed on, and system performance reliability model was set up according to the logistic relation between performance parameter of units and system output performance. Secondly the performance distributive parameters of units were estimated through statistical analysis for performance data, the values of random sample for performance data were gained according to these distributive parameters, and the system performance parameters were simulated using sample results. Finally the failure ratio of system parameters was got by using simulation results, and then the system reliability assessment can be achieved. The validity and practicality of the method were validated through an example.
