研究了旧元件组成的串并联系统和旧的串并联系统的剩余寿命和休止时间的随机比较问题.分别对失效率序、反失效率序和上转移似然比序进行了讨论,最后,当系统元件个数和旧系统或旧元件寿命是随机变量时,也给出了相应随机序的比较结果.
研究瞭舊元件組成的串併聯繫統和舊的串併聯繫統的剩餘壽命和休止時間的隨機比較問題.分彆對失效率序、反失效率序和上轉移似然比序進行瞭討論,最後,噹繫統元件箇數和舊繫統或舊元件壽命是隨機變量時,也給齣瞭相應隨機序的比較結果.

Stochastic comparisons of the inactivity time and the residual llfe between a parallel or series system of used components and a used system were developed.Cases of reversed hazard rate order,hazard rate order and up shifted likelihood ratio order were investigated,respectively.When the number of components in a system and the life of old system or old components are random,the comparison results were presented as well.
