【摘要】 针对两个比例失效率元件组成的串联系统,在热冗余的情形下,讨论了串联系统的元件冗余与系统冗余两种方案,并基于随机序的方法,对普通随机序、失效率序、反失效率序建立了元件冗余优于系统冗余的随机比较理论.更多还原

【Abstract】 In the active redundancy case,two redundancy policies were discussed of component level and system level for the series system consisting of two proportional hazards rate model components,and based on the theory of stochastic order,the stochastic comparisons results are established that component level is better than system level in the sense of the usually stochastic order,hazard rate order,reversed hazard rate order,respectively.更多还原
