Introduction: According to the characteristics of the service industry of the teaching archivists, an index system for the evaluation of the service quality of teaching archivists is established. By using the intuitionistic fuzzy set theory, the subjective evaluation information of the investigated object is converted into the intuitionistic fuzzy numbers. Based on the score function of the intuitionistic fuzzy set, a bidirectional projection-based multiple attribute decision making method with intuitionistic fuzzy numbers is developed. Through the bidirectional projection measure between each alternative decision matrix and the ideal alternative matrix, all the alternatives can be ranked to select the best one. Finally, an illustrative example related about the service quality evaluation of the teaching archivists demonstrates the application of the proposed method.
