有时可以合理地假设一个项目的寿命分布属于某个参数族，并且实际参数值取决于项目的测试环境。在双参数威布尔族设置中，假设形状和尺度参数都可表示为测试环境的函数。对于各种模型的功能依赖于环境，最大似然法被用来估计在指定的环境水平的兴趣特性。所提出的方法处理精确的、删失的和分组的数据。给出了Kevlar/环氧复合材料应力-断裂数据的详细加速寿命试验分析。
It is sometimes reasonable to assume that the lifetime distribution of an item belongs to a certain parametric family, and that actual parameter values depend upon the testing environment of the item. In the two‐parameter Weibull family setting, suppose both the shape and scale parameters are expressible as functions of the testing environment. For various models of functional dependency on environment, maximum likelihood methods are used to estimate characteristics of interest at specified environmental levels. The methodology presented handles exact, censored, and grouped data. A detailed accelerated life testing analysis of stress‐rupture data for Kevlar/epoxy composites is given.
