Yan Shu-l · Zhongguo guanli kexue · 2013
Ordering method of three-parameter interval numbers and decision-making model are studied in this paper.Firstly,a new method of the possibility ranking based on gravity center,midpoint,and the length of three-parameter interval numbers is proposed.Then,the distance formula of three-parameter numbers is established according to the most likely appearing characteristic of gravity center.Furthermore,a new attributes' weight model based on entropy measure of the three-parameter interval numbers is established.Based on the new distance formula and ordering method of three-parameter interval numbers, an uncertain decision making structure is introduced according to the TOPSIS.Finally,numeral example shows the practicality and effectiveness of the proposed method.
