摘要:A single-valued neutrosophic set is a special case of ncutrosophic set, which can describe a great deal of imprecise, uncertain and inconsistent information in the real world. Aiming at the problem of multi-attribute decision-making with the decision information presented as the form of single-valued neutrosophic sets (SVNSs). In this paper, a new method for multi-attribute decision-making (MADM) under single-valued neutrosophic environment is proposed. Firstly, the concepts of neutrosophic sets and single-valued neutrosophic sets are introduced, a distance formula based on single-valued neutrosophic sets is given. Secondly, the weighted comprehensive decision matrix is constructed. In addition, TOPSIS method is extended to single-valued neutrosophic environment, the relative closeness coefficient is used to sort the alternatives, the optimal decision-making scheme is obtained. Finally, a numerical example is given to illustrate the feasibility and effectiveness of the proposed method.
