摘要
价值工程的功能评价系数已有多种传统确定方法,并应用于实践。但这些方法都反映了决策者对功能属性的主观判断。把粗糙集理论引入价值工程中,根据粗糙集理论的属性重要度来确定功能属性的权重,克服了传统方法确定权重的主观性,所得结果与传统方法相比,更为合理和更为客观。
There are many method of evaluation about the function measurement of VE. But these methods have reflected the subjective judgement of decision-maker.Rough set theory is introduced into VE,according to calculation method of attribute importance degree in Rough Set,the weight of function attribute is ascertained.This method overcomes subjective weight given by traditional method,and the result by this method is more reasonable and objective than by traditional method.
