可靠性参数设计中评价方法和优化方法的应用研究

可靠性参数设计中实用、高效的评价方法和优化方法的研究是当前对参数设计进行应用研究的关键之一。本文对常见的一些方法进行了比较研究，阐述了绝对偏差法和序贯淘汰水平法（ＳＥＬ）与其它评价方法和优化方法相比的优势所在和不足之处。最后提出了以ＳＥＬ法与绝对偏差法结合为基础的变间隔迭代法的参数设计方法。

THE APPLICATION STUDY OF ESTIMATING AND OPTIMIZING METHODS IN PARAMETER DESIGN OF RELIABILITY

In reliability pararmeter design,the study in applicable and highly efficient estimating method and optimizing method is one of the keys in recently application study of paremeter design.The paper compares and studies some common methods,explains what the advantages and shortcoming are in SEL and absolute-bias approach compares with the other estimating method and optimizing method.Finally,proposes parameter design approach-the variable compartment itevation searching method,which based on combination of SEL and absolute-bias apporach.
