摘要

摘要本文讨论了在联合渐进II型截尾方案下威布尔分布寿命的模型参数估计和最优寿命测试计划的确定。我们在数值上获得了最大似然估计，并提出了一种改进的基于可变邻域搜索的方法来确定最优联合渐进II型截尾方案。考虑了不同的最优准则，包括成本最小化准则、a最优准则和D最优准则。灵敏度分析用于研究参数值的错误指定对最优方案的影响。

Statistical inference and optimum life-testing plans with joint progressively type-II censoring scheme

ABSTRACT This article discusses the estimation of model parameters and the determination of optimal life-testing plans for Weibull-distributed lifetimes under a joint progressive Type-II censoring scheme. We obtain the maximum likelihood estimates numerically and propose a modified variable-neighborhood-search-based approach for determining the optimum joint progressive Type-II censoring scheme. Different optimal criteria, including a cost minimization criterion, the A-optimality criterion, and the D-optimality criterion, are considered. A sensitivity analysis is used to study the effect of misspecification of parameter values on the optimal schemes.

期刊介绍： Quality Technology and Quantitative Management is an international refereed journal publishing original work in quality, reliability, queuing service systems, applied statistics (including methodology, data analysis, simulation), and their applications in business and industrial management. The journal publishes both theoretical and applied research articles using statistical methods or presenting new results, which solve or have the potential to solve real-world management problems.
