摘要
针对机械设计方案中存在的诸多模糊因素,提出了一种模糊熵权综合评价方法。该方法首先对机械设计过程中所出现的模糊因素进行分类,并建立相应的评价指标分级矩阵,随后借助信息工程中的熵权理论,利用所获得的分级矩阵中各评价指标的差异程度计算其权重,然后再对分级矩阵进行加权,最后利用信息熵实现对所选设计方案的总体评价。文末给出了实例,验证了该方法的可行性与有效性。
A new evaluation method about fuzzy and entropy weight theory is proposed for some fuzzy factors in machinery design scheme. Firstly, the fuzzy factors is classified, the corresponding classified matrix is established, secondly, the entropy weights is got according to the difference about classified matrix, the arithmetic about entropy weight is realized. The design scheme is evaluated by info entropy. Finally an example is gave and the proposed method proves to be feasible and valid.
