| Abstract: | The purpose of this paper is to study group decision making problems with three different forms of utility values, such as real number, interval number and linguistic assessment term. Firstly, the group decision making problem with different forms of utility values is introduced. Then, the computational procedure is given to solve the group decision making problems with three forms of utility values. In the method, different forms of utility values are unified into the form of interval number. And based on weighted average aggregation method, the group comprehensive evaluation value of every alternative is obtained. The result of alternatives selection is determined by means of the obtained group comprehensive evaluation value. Finally, a numerical example is used to illustrate the use of the proposed method. |
