摘要

为了研究机内测试(BIT)对系统的作用和影响,选择不同的BIT及其检测策略,应用Simulink仿真软件对具有机内测试设备(BITE)的复杂可修系统进行了建模与仿真.利用仿真模型对不同类型的BITE、维修时间、错误率等因素对系统可用度的影响进行了仿真评估,结果表明:上述因素对系统可用度有着不同的影响.基于Simulink的复杂可修系统仿真方法为研究BIT对系统的作用和影响,选择不同的BIT及其检测策略评估提供了一条技术途径.%In order to research the effects of built-in test (BIT) on the system and select BIT and test strategy, the modeling and simulation methods for complex system based on Simulink are put forth. The influences of the different types built-in test equipment ( BITE), maintenance time and error rate on the system usability are simulated and evaluated by using the model. The simulation results show that the different types of BITE, maintenance time and error rate have different effects on the system. The simulation method for complex system based on Simulink provides a technique approach to research the effects of BIT on the system, select BIT and evaluate the test strategy.
