| 摘 要： | 对于高可靠长寿命产品,基于性能退化数据分析产品可靠性是一种行之有效的技术途径。由于有时无法用确定的物理/化学过程定量描述性能退化过程,借助随机过程方法建立退化模型是有效的技术途径。提出了基于Poisson-Normal过程的性能退化模型,给出了参数估计算法和可靠性估计的计算公式,结合实例说明了方法的有效性。

| Abstract: | Using degradation measurement of product performance over time to analyze product reliability is an effective approach for high-reliability or long-life products.Because sometimes performance degradation process is unable to quantify in physics and chemistry,using statistics process to modeling performance degradation is an alternative approach.Firstly a model based on Poisson-Normal process is proposed.The parameters(evaluation) arithmetic and the calculation formula for reliability evaluation are presented.Specially,an example is given to show the validity of this method. |
