模糊白化灰色关联理论在设计评价中的应用

由于设计方案评价指标存在着模糊性和不确定性,在编制设计方案评选办法时,利用层次分析法确定各个评价指标的相对权重;设计方案评价所涉及的信息大部分属于不确定量,具有模糊性,且各因素间并非具有数量上的确定关系,信息的可知性差,具有灰色性,针对该特点,文章建立了基于模＃糊白化灰色关联理论的设计方案评价模型,并利用该模型对具体工程设计方案进行评价,结果显示该评价简便实用,客观准确.

Application of fuzzy white grey correlation theory in design scheme evaluation

Due to the fuzziness and uncertainty of design scheme evaluation indexes, Analytic Hierarchy Process is adopted to determine the relative weight of individual index in design scheme evaluation. The information involved in the evaluation of design schemes is often fuzzy, grey, without def- inite quantitative correlation. Aimed at the fuzziness and uncertainty of evaluation information, a model for evaluating design scheme based on the fuzzy white grey correlation theory is established and used to evaluate concrete design schemes of construction projects. The results show that the evaluating model is impersonal, simple, and of practicability.
