模糊命题逻辑形式系统 FLcom 在模糊决策中的应用

摘要

FLcom是一种与模糊集FScom相对应的区分矛盾否定、对立否定和中介否定的模糊命题逻辑形式系统。基于FLcom，以一金融决策为实例，利用距离比率函数为模糊命题公式赋值，给出一种确定FLcom语义模型中λ值的方法，并结合模糊产生式规则，给出基于FLcom的模糊产生式规则的一般形式的意义，同时讨论了FLcom在模糊决策中的应用。%FLcom is a fuzzy propositional logic formal system with regard to contradictory negation ,opposite negation and medium negation which corresponds to fuzzy set FScom .Based on FLcom theory ,in this paper we take a decision-making for finance as the example ,use dis-tance ratio function to assign value on fuzzy propositional formula ,and present a method to determine the value of λin semantic model of FL-com,as well as present the meaning of general form in regard to FLcom-based fuzzy production rule in combination of such rule .Moreover,we discuss the application of FLcom in fuzzy decision-making.
