The Decision-making Model of Harden Grey Target Based on Interval Number with Preference Information on Alternatives.

This paper presents a new decision-making model of harden grey target based on a measure transformation method, to study the problem of grey decision with interval numbers in which the decision-maker has certain preference information. First, a measure transformation method for normalized treatment of interval numbers is proposed, in order to select the harden decision-making interval through minimizing the measure of the interval of situation effect, which can improve the decision quality. Then, programming model is established based on minimizing the square sum of distance, and index weights are confirmed by constructing the lagrange function. The model of harden grey target based on interval number with preference information is derived. The validity and practicability are illustrated with an example. [ABSTRACT FROM AUTHOR]
