Abstract

Paper [1] has proposed that negation of the fuzzy knowledge include 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). To show the applicability of FScom, it was applied in an example about the stock investment decision-making. An approach to confirm the membership functions of fuzzy sets is presented. Threshold value of range of membership degree is established. Reasoning and realization of fuzzy decision making in the example is discussed based on FScom and the fuzzy production rule. It implies that the application of FScom in dealing with practical problems with ambiguity and different negations is effective.
