Decision-making Approach Based on Novel Linguistic Preference

A new three-point interval number linguistic preference judgment matrix based on single number linguistic preference judgment matrix is put forward. This construction approach on this preference is given and the characteristic of its consistency is studied. Based on the complete consistency definition of three-point interval number linguistic preference judgment matrix, the model of weight solution is suggested, and to study the adjustment method when judgment matrix deviation does not match the decision-makers´ critical standards. At last, the model validity is proved by an example.
