An Economic Based-Approach for Library System Selection

Purpose of this paper: There are ways to rank competitive alternatives but ranking competing alternatives in terms of their overall performance with respect to some criterions in fuzzy environment is possible by the use of fuzzy TOPSIS methodology. Author discusses a fuzzy multi-criteria method based upon the fuzzy model and concepts of positive ideal and negative ideal solution points for solving problems with a group of multi decision makers. The fuzzy sets concepts are used to evaluate the performance of alternatives and the importanc Design/methodology/approach: First Fuzzy TOPSIS methodology is fully described. Then a case study comprised of four main criteria and five alternatives is constructed and solved by the proposed method and the results are analyzed. Findings: The TOPSIS methodology used in this article is able to grasp the ambiguity exists in the utilized information and the fuzziness appears in the human judgments and preferences. TOPSIS technique can easily produce satisfactory results, and hence stimulates creativity and the invention for developing new methods and alternative approacs Practical implications (if applicable): This article is a very useful source of information for Fuzzy TOPSIS and decision making using more than one decision makers in fuzzy environment. What is original/value of paper: Due to the fact that a better management of a system is related to the full understanding of the technologies implemented and the system under consideration, sufficient background on the methodologies are provided and a case study is developed and solved.
