New interactive multi-objective decision-making method and its application to water resources system planning

Abstract

Based on objective satisfaction degree and objective comprehensive degree, a new interactive multi-objective decision-making method is proposed. The function of objective comprehensive degree is described by the Euclid distance, so that the objective weight, usually given by subjective experience, can be avoided. The new method can reflect the objective wishes of the policy-maker in the full decision-making process, and there is more objective and less subjective effect. The results show that this method is reasonable in practice, and can be used in water resources system planning.
