A New Drug Risk Assessment Model of Comprehensive Hospitals

Based on the fuzzy approximation theory of intuitionistic fuzzy sets, the paper studied a transformation method from an intuitionistic fuzzy complementary judgment matrix to a fuzzy approximation matrix, and introduced an analytic hierarchy process under the intuitionistic fuzzy environment which was called intuitionistic fuzzy analytic hierarchy process. Then it was applied in the risk evaluation problem of medical institutions and helped to get the weight of each risk category. After examination, it proved intuitionistic fuzzy analytic hierarchy process was more effective than other methods for drug risk assessment of medical institutions.
