Weibull分布环境因子工程计算方法

摘要

目前,常用的指数型环境因子计算公式缺乏广泛的适用性,不能适用小样本失效数据或零失效数据的情况,尽管工程中有相应的处理方法,但因有人为因素的影响使其结果不够客观.针对这一问题,提出Weibull分布环境因子小概率评估法,并给出工程具体实施方法,使结果更合理,更具实用价值.%At present, as the calculation formula for environmental factors of exponential datum used is not always applicable widely, it is not usable in the case when the failure count of the system tested is small or zero. Even though there are appropriate disposal methods in engineering, it isn't objective because of the factors caused by men. Accordingly, the little probability estimation method for Weibull distribution environment factors is put forward and a implementing way in engineering is given. In this way, the result is more reasonable, and can be used practically.
