In this paper, the interval positive ideal point and interval negative ideal point have been defined based on the possibilistic interval mean value of fuzzy numbers, the relative approximate dominance degree and fuzziness dominance degree of the fuzzy numbers have been defined based on distance formula of interval numbers and the fuzziness degree, with the composite of them, a new ranking method has...
In this paper, the characteristic index vectors, positive and negative ideal characteristic index vector of fuzzy numbers are defined, based on the characteristic quantity of fuzzy number.Then, the ranking index is proposed according to the given fuzzy numberpsilas linear weighted distance between characteristic index vector and positive /negative ideal characteristic index vector, respectively.Finally,...
