威布尔分布下结构可靠度P_r(Y_n>a_1Y_1+…+a_(n-1)Y_(n-1))的估计

The estimation of structural reliability P_r(Y_n>a_1Y_1+...+a_(n-1)Y_(n-1)) in the Weibul case

在Y1 ,… ,Yn- 1 ,Yn 相互独立且服从威布尔分布情况下得到结构可靠度Pr(Yn >a1 Y1 +… +an- 1 Yn - 1 )

In this paper, minimum variance unbiased estimation and lower confidence limits of the structure reliability P r(Y n>a 1Y 1+...+a n-1 Y n-1 ) are obtained, where Y 1, ..., Y n-1 , Y n are all independent and Weibul variables.
