| 摘 要： | 设结构系统由n个结构性部件串联组成。设部件i的强度X_i～Γ(λ,ν),λ,ν>0,i=1,…,n;系统应力Y～Γ(μ,α),μ,α>0。X_1,…,X_n,Y相互独立。当ν,α已知,λ,μ未知时,本文给出串联结构系统可靠度R_n的MVUE_n、MLE_n和UMAU置信区间。本文还考虑了(?)_n与(?)_n的渐近关系,并证明了(?)_n和(?)_n都是R_n的相合渐近正态估计。本文的所有结果都可以推广到k/n(G)结构系统。 |
| 关 键 词： | 串联结构系统 可靠度 最小方差无偏估计 极大似然估计 一致最精确的无偏置信区间 相合渐近正态估计 |

| Abstract: | MVUER_n, MLER_n, UMAU confident interval of reliability for a series stressstrength system in a Gamma-Gamma model are given in this article. The asymptotieal relation of R_n and R_n is considered in the article. We prove that R_n and R_n are all consistent asymptotically normal estimations of reliability. |
| Keywords: | series stress-strength system reliability minimum variance unbiased estimation maximum likelihood estimation uniformly most accurate unbiased confident interval consistent asymptotically normal estimation |
