Methods for triangular fuzzy number multi-attribute decision making with given preference information on alternative
Gong Yan-bing · Kongzhi yu juece · 2012
The multi-attribute decision making problem is studied,in which the information on alternatives preference is given,attribute weights are unknown partly and the attribute values are given in the forms of triangular fuzzy numbers.Two decision methods are proposed,one is the fuzzy proportional value decision method,and the other is the degree of fuzzy deviation decision method.By using two methods,two linear programming models are established firstly,and the attribute weights are derived by solving two models.And then based on a possibility degree formula for comparing two triangular fuzzy numbers and a formula for priorities of triangular fuzzy numbers,the decision alternatives are ranked.Finally,a numerical example shows the feasibility and effectiveness of the two methods.
