定时截尾情况下简单加速寿命试验优化设计的比较

Comparison of Optimum Design of Accelerated Life Tests

摘要: 本义讨论了定时截尾情况下简单恒加试验和简单步加试验的最优设计问题；在一定条件下证明了最优步加试验优于最优恒加试验．给出了一个寻求简单步加试验最优设计的近似方法．数值例子表明，这种近似是可行的。

Abstract: This paper presents optimum plans of simple constant -stress accelerate life test （CSALT）and simple step- stress accelerate life test （SSALT）under Type I. We prove that the optimum SSALT is better than optimum CSALT. Finally we provide several examples to illuminate the feasibility of the approximate method.
