摘　　要：对于模糊知识中不同"否定"的认知与处理,文献[1]从概念层面上区分模糊知识中3种不同的否定关系,并提出一种具有矛盾否定、对立否定和中介否定的模糊集FScom。对FScom在股票投资决策方面的应用做了研究,以表明FScom处理实际问题的适用性。并基于FScom,讨论了决策规则中的模糊集及其不同否定的区分与形式表示;给出一种确定模糊集及其不同否定集的隶属函数以及阈值的方法;采用模糊产生式规则,讨论了实例中的模糊推理与决策。从而表明,FScom用来处理具有模糊性并且存在不同否定的实际问题是有效的。For the cognition and processing of different negations of the fuzzy knowledge, paper [1]has proposed that negation of fuzzy knowledge including the contradictory negation, the opposite negation and the medium negation, and defined a new fuzzy set with contradictory negation, opposite negation and medium negation （FScom）. In order to show applicability of FScom, the fuzzy set with three different negations （FScom） was applied in the stock investment deci- sion-making. Based on FScom, this paper introduced an approach to define the membership function of the fuzzy set and its different negations in decision rules,and discussed the threshold value of range of membership degree and its mea- ning. Finally,it discussed reasoning and realization of fuzzy decision-making in the example based on FScom and the fuzzy production rule. The final decision results were given out. The decision-making process implies that the application of FScom in dealing with practical problems with ambiguity and different negations is effective.
