摘要

在本研究中，我们提出了两种估计量，称为三步MML和改进威布尔分布参数的组合估计量，用于具有浴缸形故障率函数的可靠性模型。仿真结果表明，这两种估计方法都优于图形估计方法。特别是，组合估计器是两者中更好的。两个实际数据应用也显示了与图形估计器相比，所提出的估计器的优越性。

Estimation of the Parameters of the Modified Weibull Distribution with Bathtub-shaped Failure Rate Function

In this study, we propose two estimators called the 3-step MML and the combined estimators of the parameters of the modified Weibull distribution which is used in reliability models with bathtub-shaped failure rate function. The simulations show the superiority of both estimators over the graphical estimators. Particularly, the combined estimators are the better of the two. Two real-life data applications also show the superiority of the proposed estimators compared to the graphical estimators.
