RT Monograph SR 00 A1 Granat, J. A1 Wierzbicki, A.P. T1 Interactive Specification of DSS User Preferences in Terms of Fuzzy Sets YR 1994 FD 1994-05 SP 29 AB The specification of reference levels in the aspiration-led methodology of multiobjective decision support is usually imprecise. Such imprecision can be included in the mathematical formulation of a decision problem by using membership functions and fuzzy set theory. This approach can also be treated as a further development of fuzzy interactive methods. A method of constructing order-consistent scalarizing function based on membership functions is presented as well as a related, extended fuzzy interactive method.
