摘要：This paper presents a group multi - criteria DEMATEL and VIKOR decision analysis method with interval type - 2 fuzzy sets. In order to compare normal fuzzy trapezoidal numbers, we convert them into crisp values using graded mean integration representation. By a case study for selection of business intelligence platform, we prove that the proposed combination is a feasible solution that can work with benefits and costs criteria, while also reducing uncertainty in experts' assessments
