标题： Testing Exponentiality Against a Trend Change in Mean Time to Failure in Age Replacement

摘要： 年龄更换中的平均故障时间评估了年龄更换策略的性能和效果。 在本文中，我们提出了一种针对年龄更换中平均故障时间趋势变化的指数性检验。 我们在零假设下推导了检验统计量的渐近分布，以近似临界值。 我们进行了一项模拟研究，以调查所提出的检验性能，并将其与文献中一些已知检验进行比较。 显示英文摘要

摘要： Mean time to failure in age replacement evaluates the performance and effectiveness of the age replacement policy. In this paper, we propose a test for exponentiality against a trend change in mean time to failure in age replacement. We derive the asymptotic distribution of the test statistics under the null hypothesis to approximate the critical values. We conduct a simulation study to investigate the performance of the proposed test and compare it with some well known tests in the literature.
