基于不同的最优性准则，文献中建立了几种经典年龄替代政策的优化模型。这就提出了如何在这些模型中为特定的应用程序选择合适的模型的问题。本文通过对这些模型的性能和一种新的风险敏感成本模型进行比较研究来解决这一问题。从成本（或可用性）和可靠性两个方面对优化模型解的性能进行评价。定义了与这两个方面相对应的两个标杆点；并分别建立了与成本、可靠性和综合性能相对应的三个性能指标来评价模型的性能。通过定量比较模型解在威布尔分布、伽玛分布和对数正态分布下的性能，识别出性能突出的模型。讨论了优秀模型的适用情况。研究结果对维修研究人员和实践者都很有用。
Several optimization models of the classic age replacement policy have been developed based on different optimality criteria in the literature. This raises the issue how to choose an appropriate model among these models for a specific application. This paper addresses this issue by carrying out a comparative study for the performances of these models and a new risk-sensitive cost model. The performance of the solution of an optimization model is evaluated from two aspects: cost (or availability) and reliability. Two benchmarking points that correspond to these two aspects are defined; and three performance measures that correspond to cost, reliability and overall performance, respectively, are developed for evaluating the performances of the models. Through quantitatively comparing the performances of the models’ solutions associated with the Weibull, gamma and lognormal distributions, the models with outstanding performances are identified. The applicable situations of the outstanding models are also discussed. The results are useful for both maintenance researchers and practitioners.
