基于ExtendSim的系统可靠性建模

针对传统可靠性仿真模型建模繁琐,编程困难的问题,建立了基于Ex tendS im的可靠性模型,即串联、并联、旁联模型,相比传统方法具有建模直观、调试方便等优点,并以某混联系统为例与解析模型进行了对比验证,仿真结果表明,建立的可靠性模型是可信的,且此模型不依赖于单元寿命分布,相比解析模型具有更强的适应性。

Research on System Reliability Modeling Based on ExtendSim

To address the problem of tedious modeling and difficult programming of traditional reliability simulation model,the reliability models,including serial model,parallel model,and standby model are built based on ExtendSim.The modeling method is intuitional and convenience debugging.A compound system is presented as an example in the case study.The result shows that the reliability models are believable.Compared with analytical model,the models don’t rely on fallibility distribution of unit,which makes the models apply more widely.
