The fuzzy sets theory cannot accurately reflect the hesitation or abstention of decision makers. In view of this problem, introducing the intuitionistic fuzzy sets, we put forward a credit risk evaluation model of big data enterprises based on intuitionistic fuzzy sets. Firstly, a credit risk evaluation index system of big data enterprises was constructed. Meanwhile, the intuitionistic fuzzy weights of indicators were determined with intuitionistic fuzzy AHP. Secondly, we constructed the IFWA operator, and then the intuitionistic fuzzy comprehensive evaluation value of sample enterprise was calculated. Finally, we used the score function of intuitionistic fuzzy number to calculate the credit comprehensive score and ranking of sample enterprise. Taking three listed companies in big data industry in China as sample, we used the above model to carry out an example analysis. The result of example analysis proves the feasibility and effectiveness of this model.
