若令随机向量(X1,X2)表示系统中两元件的寿命,则X(1)=min(X1,X2)和X(2)=man(X1,X2)就表示两个元件组成的串并联系统的寿命.在文本中,我们主要考虑(X1,X2)不可交换而联合分布为二维Lomax分布情形下,X(1)和X(2)的相依性关系,并从随机比较的角度讨论了串并联系统的性质.
若令隨機嚮量(X1,X2)錶示繫統中兩元件的壽命,則X(1)=min(X1,X2)和X(2)=man(X1,X2)就錶示兩箇元件組成的串併聯繫統的壽命.在文本中,我們主要攷慮(X1,X2)不可交換而聯閤分佈為二維Lomax分佈情形下,X(1)和X(2)的相依性關繫,併從隨機比較的角度討論瞭串併聯繫統的性質.

Let the random vector ( Xt, X2) be the the lifetimes of the two components in a system, the lifetimes of the series and the parallel structure can be expressed by order statistics X(1) = rain( X1, X2) and X(2) = max( X1, X2), respectively. In this note, we consider the dependence of XO) and X(2) in the case that (X1, X2)is non - exchangeable and the joint distribution is a bivariate Loman distribution,and discuss the properties of series and parallel systems from stochastic comparirons.
