摘　　要：针对目前产品水平评价中存在的片面性和主观性问题,采用国际上公认的评价原则,深入探讨了电磁流量计产品水平综合评价指标体系,在尊重用户意见的基础上,提出了专家的主观权值和理论计算客观权值相结合综合度量值.研究了不同类别指标的熵权和模糊计算模型,以及多指标加权综合评价方法.该方法有助于解决当前产品水平评价中的共性问题,也为用户选择产品提供了理论参考.With regard to the problem about one-sided and subjective in product level evaluation,using evaluation principles accepted internationally,we investigate comprehensive evaluation index system of electromagnetic flowmeter＇s product level.Respecting the views of users,comprehensive measure obtained from combining a subjective expert＇s evaluation weight with objective entropy weight is presented.Entropy of different types of indicator models and fuzzy calculation models,as well as a comprehensive evaluation method about multi-index weighting are presented.The method can effectively solve the problem existing in current modeling,and is effective for engineering application.This approach helps to solve the common problems existing in current product level evaluation,and provide theoretical reference for the user when they select products.
