Research the priority methods of interval numbers complementary judgment matrix

In this paper, firstly, a consistency definition for interval numbers complementary judgment matrix and its consistency sufficient condition are proposed. Secondly, two priority methods for interval numbers complementary judgment matrix, which are least square method and linear goal programming method, are proposed. Thirdly, a new method for the creation of interval number comprehensive judgment matrix is proposed. Finally, numerical examples are given to show their feasibility and effectiveness.
