ABSTRACT
According to the decision-making preference structure, the group decision-making aggregation approach includes the aggregation on the same kind of preference structure and the different kind of preference structure. The study on the aggregation of the same kind of preference structure has received much attention, but study of the aggregation of the different kinds of preference structures is still a new field. Decision makers would probably provide different preference structures due to the difference of their knowledge structure, judgment level, and individual preference. In addition, due to the development of intelligent decision-making support systems integrated by communications technology and computer technology, the practicality and feasibility of group decision-making technology
should be improved. A new way to express the decision maker’s preference via the three-point interval number comparison matrix is put forward. In addition, the approach on the aggregation of uncertain preference based on the three-point interval number reciprocal comparison matrix and complementary comparison matrix is studied.
