一种改进的可靠性参数设计方法

An Improved Method of Reliability Parameter Design

对参数设计中序贯淘汰水平法（ＳＥＬ）和绝对偏差法进行了研究和改进，提出了以ＳＥＬ法与绝对偏差法结合为基础的自动变间隔迭代搜索法。针对不同的典型实例与以前的参数设计方法进行比较，结果证明该方法高效可靠，且具有较好的可操作性。为工程实用奠定了一定的基础。

The SEL and the absolute bias approach for parameter design are studied and improved, on the basis of which the variable compartment iteration searching method is advanced in this paper. Also, a comparison is made with the different typical actual examples and the previous parameter design method. The results prove that this method is highly efficient and reliable with better operationability, thus, laying a solid foundation for the practical use in engineering.
