摘要
定义产品平均寿命为一个模糊数表示,用模糊数估计系统可靠度、系统寿命、系统失效率。给出了单个部件、串联系统和并联系统的一些结果。对于比较难用解析法解决的问题,借助于计算机采用区间法可容易解决,并给出了应用实例。
The MTTR is defined as a fuzzy number. The fuzzy numbers are used for evaluating system reliability, system MTTR and system failure rate. Some results of single component, series system and parallel system are given. The interval method with computer can solve difficult problems, which can' t be solved by analytic formula. Finally, an example is given.
