As stressed in [1] and [12] an interesting question on philosophy of probability is to assign probabilistic valuations to individual phenomenon. In [10] such a question was discussed and a solution was proposed. In this chapter we start from the ideas in
fuzzy set can be denoted as: ( ) ( ) { } U x x x A A ! = ~ , ~ µ (1) where U is discourse, i x is the element in U , A ~ is a fuzzy set in U , and A ~ µ is the membership function for any U x i ! whose output is located between 0 and 1...

Preferences form a reciprocal fuzzy PC matrix and the confidence values are arranged into a symmetric fuzzy confidence matrix. Both matrices constitute the input of the model, while the output is a fuzzy priority vector. In both models, confidence values are applied to assess the reliability of ...
6) indefinite set 不确定性集合 1. The paper analyzed similarities and differences between fuzzy set and rough set,pointes out the shortages and defects of fuzzy set,and then defined a new indefinite set,called unascertained set,where the shortages and defects of fuzzy set can be compensated ...

Also Intuitionistic fuzzy equivalence classes have been characterized with the help of (α, β)-cut of Intuitionistic fuzzy relations and finally for any Intuitionistic fuzzy equivalence relation on a finite set, we have given an upper bound of the number of values that the degree of......
