TOPSIS-Based Multi-Criteria Group Decision Making under Heterogeneous Information Setting
This paper presents a multi-criteria group decision making method based TOPSIS, which can be used to deal with heterogeneous information(the numerical, interval valued and linguistic variable with different granularity). The uniform and aggregation of the heterogeneous information is investigated to effectively avoid loss of information. The OWA Operator based on separation measures is constructed. Finally, a numerical experiment is used to illustrate the feasibility of the proposed method.
