Description
Summary:In this paper, we propose an expert decision making method, UL-TOPSIS. Through giving experts the flexibility of evaluation, they can choose two items of linguistic variables by the multiple-choice method, with an interval range of uncertain linguistic variables to express their real thinking. The method is also used to resolve the problem of too wide range of an individual expert opinion or too large differences between experts opinions. We hope that the new method can capture the opinions of experts better, integrate the opinions of all experts appropriately, and make more accurate decisions for decision makers.
