The consistency and the priority method of three-point interval number Reciproca judgment matrix are studied.Based on the definition of three-point interval number reciproca judgment matrix,the relations between the consistency and the the weight vector for three-point interval number reciproca judgment matrix discussed.Then,a linear programming model is established,and the weight vector of threepoint interval number reciproca judgment matrix is obtained.By using the expectations of three-point interval number reciproca judgment matrix,the decision alternatives are ranked.Finally,some numerical examples illustrate the effectiveness and practicality of the proposed methods.
