威布尔分布是可靠性学科中的一个重要分布。本文利用灰色系统理论中的方法,提出了一种新的两参数威布尔分布的点估值方法,该方法使用累加生成技术,对累积失效率函数的原始试验数据进行处理,建立了估值公式。该方法简单实用,不需查表或作图,其估值精度满足工程应用的要求,可以得到比较满意的结果. Weibull distribution is an important distribution in reliability science. In this paper, a new two-parameter Weibull distribution point estimation method is proposed by using the method in gray system theory. This method uses the cumulative generation technique to process the original experimental data of cumulative failure rate function, and establishes the valuation formula . The method is simple and practical, does not need to look up table or chart, its valuation accuracy to meet the requirements of engineering applications, you can get more satisfactory results.
