利用变环境试验数据的可靠性灵敏度分析

研究了环境因素对产品可靠性的影响,提出了一种利用变环境试验数据的可靠性灵敏度分析方法.首先针对产品寿命服从位置-刻度模型的情形,利用径向基函数法来度量不同环境因素及其交互作用对可靠性的影响,建立了关于环境因素的位置参数模型.接着利用Poisson分布来描述似然函数中的示性变量,利用广义线性模型给出了可靠性模型参数的极大...

Reliability Sensitivity Analysis Using Variable Environment Test Data

Many products always operate under various complex environment conditions.To describe the dynamic influence of environment factors on their reliability,a method of reliability sensitivity analysis using variable environment test data is proposed.In this method,a location scale model is introduced to relate the reliability to environment factors.And the location parameter is assumed as a function of relevant environment variables while the scale parameter is assumed as an unknown positive constant.Then,the l...
