在实际中，许多部件的寿命分布通常具有浴盆形状的失效率。然而，用于模拟这种类型失效率函数的实用模型却很少。在本文中，我们研究了一个基于两个威布尔生存函数相加的简单模型。还给出了该模型的一些简化形式。基于常规威布尔图的图形估计技术在这种情况下被证明是有用的。（C）爱思唯尔科学有限公司。
Lifetime distributions for many components usually have a bathtub-shaped failure rate in practice. However, there are very few practical models to model this type of failure rate function. In this paper we study a simple model based on adding two Weibull survival functions. Some simplifications of the model are also presented. The graphical estimation technique based on the conventional Weibull plot is demonstrated to be useful in this case. (C) Elsevier Science Limited.
