Multicriteria Fuzzy Decision Making Method Based on Interval-valued Vague Set
Interval-valued vague set,as a useful generalization of vague set,has achieved great success in many application areas,such as system control and intelligent decision. By regarding the set of constraint condition attributes as an interval-valued vague set and considering all the interval degree of membership,non-membership and hesitation (or abstention) of the constraint conditions,an effective multicriteria fuzzy decision making method based on our proposed score function of interval-valued vague value is presented for handling fuzzy decision problem frequently occurred in uncertain system processing. At last,a numerical example is given to illustrate the effectiveness and practicability of the presented method.
