Aiming at the multiple services with the same or similar function,a hybrid multi-attribute Web service selection based on intuitionistic fuzzy theory was proposed. The QoS attributes were divided into the exact numeric type, interval numeric type and linguistic type. The calculation method for the QoS preference of users was obtained with the analytic hierarchy process( AHP). In addition,the intuitionistic fuzzy set( IFS) theory was introduced to unify the hybrid QoS attributes into the intuitionistic fuzzy number,and the intuitionistic fuzzy weighted arithmetic average operator was used to assemble the indexes of QoS decision matrix. Moreover,the ranking for each decision scheme was performed with the intuitionistic fuzzy scoring function,and the Web service selection based on QoS was realized. The results of example verification showthat the proposed method has certain effectiveness.
