A novel model for dynamic multi- attributes group decision-making based on vague set and its TOPSIS solution

摘要

In view of the existing problem in four-dimensional decision-making consisting of alternative set, attribute set, time set and valuator set, a novel model for dynamic multi- attribute group decision-making based on vague set and its TOPSIS solution are put forward. Firstly, the relationship between vague set and linguistic variable set is defined. Secondly, a mathematical description of dynamic multi- attribute group decision-making problem based on vague set is presented. Thirdly, how to find the model's solution and its steps are given in detail. Finally, the proposed approach is applied and the result shows it effective and feasible.
