We consider the occurrence of warranty claims for automobiles when both age and mileage accumulation may affect failure. The presence of both age and mileage limits on warranties creates interesting problems for the analysis of failures. We propose a family of models that relates failure to time and mileage accumulation. Methods for fitting the models based on warranty data and supplementary information about mileage accumulation are presented and illustrated on some real data. The general problem of modelling failures in equipment when both time and usage are factors is discussed.
我们考虑在车龄和里程数积累都可能影响故障发生的情况下汽车保修索赔的情况。保修条款中同时存在车龄和里程数限制给故障分析带来了有趣的问题。我们提出了一系列将故障与时间和里程数积累联系起来的模型。给出了基于保修数据和有关里程数积累的补充信息来拟合这些模型的方法，并在一些实际数据上进行了说明。讨论了在时间和使用情况都是影响因素时对设备故障进行建模的一般问题。
