Abstract: Aiming at the problem of data product selection under the linguistic evaluation information environment, a data product selection model based on additive consistency improving algorithm of linguistic preference relation is designed. Based on the linguistic preference relation information provided by experts, a method to measure the consistency level of linguistic preference relation is introduced, and a construction model of complete additive consistency linguistic preference relation is proposed. A convergent data product selection model is constructed, which is based on the linguistic preference relation consistency improving algorithm. An example of data product selection is given. It is found that the decision-making algorithm is more reliable and effective.
