具有关闭准则的两部件串联系统的可靠性分析

Analysis On Reliability of Two Assemblies series System With closed Criterion

对于两部件 ,一个修理工的串联系统的研究是个由简入深的过程 .最初 ,曹晋华和程侃研究了两部件及修理时间均服从指数分布的情况 ,应用的是Markow理论 .接着史定华研究了只有一个部件的寿命服从指数分布 ,而其他变量均服从一般分布的情况 .但这两种情况均假设部件能够“修复如新” .在改变这一条件下 ,东南大学的张元林和吴少敏连续发表了两篇文章 :第一篇假设一个部件不能“修复如新” ;第二篇假设两部件均不能“修复如新” .本篇是在第二篇基础上加进单向关闭条件 ,利用补充变量法研究系统的可靠性指标 .

A repairer's research on two assemblies series system is a process from the easy stage to the difficult and complicated one.At first,Cao jin-hua and cheng kan have studied both the two assemblies and repair time with the Markow theory.Then,Shi ding-hua has studied the situation that only one assembly's service life submits the exponent distribution,while other variables all submit the ordinary distribution.But both of the two situations are supposed that the assembly can be“repaired to the original condition”.Changing this situation,Zhang yuan-lin and Wu shao-min in dong Nan University have continually published two essays.In the first essay it is supposed that one of the two assemblies con not be “repaired to the original condition”;Based on the second essay my essay has added one-way-close condition and studied the system's reliability index with supplementary variable algorithm.
