A fuzzy ANP with interval type-2 fuzzy sets approach to evaluate enterprise technological innovation ability

In order to overcome the drawbacks of AHP in solving complex decision-making problems, ANP is applied in the evaluation of enterprise technology innovation ability. Due to Interval type-2 fuzzy sets can handle uncertainty of linguistic variables in a more flexible and precisely way than Type-1 fuzzy sets with their fuzzy membership functions, a fuzzy ANP method with interval type-2 fuzzy sets is proposed to evaluate the enterprise technology innovation ability. A new ranking method based on the centroid is applied in processing relationships between interval type-2 fuzzy sets. And the proposed method is used in the numerical examples and ranking results are obtained.
