本文提出了一种设计具有非线性应力-寿命关系的定数截尾恒定应力加速寿命试验（ALT）最优方案的方法。该方法以线段为基础，推导出最优方案连接对应于非线性应力-寿命关系的曲线或曲面的最高点和最低点的弦，因此，它将具有单变量或多变量非线性应力-寿命关系的ALT最优方案设计问题转化为具有单变量线性应力的ALT最优方案设计问题，生活关系。理论分析和算例表明，与基于非线性应力-寿命关系本身寻找最优方案的方法相比，该方法可以简化设计问题，获得更优的方案。
This paper proposes a method for designing an optimal plan for the type-I censoring constant-stress accelerated life test (ALT) with a nonlinear stress-life relationship. This method derives the optimal plan based on the line segment (the chord) that connects the highest and lowest points of the curve or surface that corresponds to the nonlinear stress-life relationship, and consequently, it transforms the problem of designing the optimal plan of an ALT with a univariate or multivariate nonlinear stress-life relationship to the problem of designing the optimal plan of an ALT with a univariate linear stress-life relationship. The theoretical analysis and examples show that compared with the methods that find the optimal plan based on the nonlinear stress-life relationship itself, the proposed method can simplify the design problem and obtain better plans.
