| 摘 要： | 在假设产品寿命服从对数正态分布情况下，提出了用分散系数法评估极小子样产品的可靠性。介绍了2种求解分散系数的公式。分散系数的大小影响产品的可靠性，而寿命标准差又是决定分散系数大小的主要因素之一。运用极大熵原理和模糊综合分析，讨论了寿命标准差的具体求法。通过实例介绍了该方法的具体运用。

| Abstract: | Given that product life follows lognormal distribution,fatigue life scatter factor method (LSF) is applied to evaluating the reliability of product with 1 or 2 samples.Two formulas for calculating LSF are introduced.The value of LSF has influence on product reliability and the product life standard error (LSE) is one of main factors that determine LSF.A method for calculating LSE based on maximum entropy principle and fuzzy synthesis analysis is proposed and an example is given to illustrate how to use it. |
