Abstract: 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 three-point 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.

Key words: multi-attribute decision, three-point interval number, reciproca judgment matrix, priority
