两参数威布尔分布已被广泛用于产品和部件使用寿命的建模。在本文中，我们研究形状参数对失效率以及在维护和可靠性提高方面三个重要变量的影响。这些变量是：（i）失效时间，（ii）基于风险的更换年龄，（iii）剩余寿命。我们基于形状参数提出一种分布的分类方案，并讨论结果的应用。© 2011爱思唯尔有限公司。保留所有权利。
The two-parameter Weibull distribution has been widely used for modelling the lifetime of products and components. In this paper we study the effect of the shape parameter on the failure rate and three variables of importance in the context of maintenance and reliability improvement. These variables are (i) time to failure, (ii) age at replacement based on risk and (iii) residual life. We propose a classification scheme for the distribution based on the shape parameter and discuss the application of the results. (C) 2011 Elsevier Ltd. All rights reserved.
