College of Mathematics and Computer Science, Guangdong Ocean University


Academic libraries play a significant role in providing core services that include research, teaching and learning. User
satisfaction is an important indicator for evaluating the performance of library service. This paper develops a method
for measuring the user satisfaction in a group decision-making environment. First, the performance of service is
evaluated by using questionnaire survey. The scores are recorded by using some simple symbols. Second, the symbol
information along with nonresponse items in questionnaires are fused into an intuitionistic fuzzy information. Third, an
experimental analysis is provided to illustrate the validity and effectiveness of introduced method in this paper. Finally,
the theoretical and practical implications of current model are discussed, the important limitations are recognized, and
some main advantages and future research directions of current method are shown in conclusions.
