• Resumen

  • In this paper, we developed a web-based decision making tool which utilizes fuzzy analytic hierarchy process (AHP) methodology to solve daily complicated decision making problems. Fuzzy concepts are used to enhance the traditional AHP, which is mainly applied in crisps decision environment. Fuzzy linguistic term approach is applied to capture the fuzziness and subjectiveness of decision makers’ judgements. Due to simplicity and effectiveness, we selected triangular fuzzy numbers as a reference to indicate the influence strength of each element in the hierarchy structure. α-cut-based method has been utilized to prevent the controversial of fuzzy number ranking process. The confidence level and the optimistic level of decision maker are captured by using α-cutbased fuzzy number results. A numerical example is demonstrated to illustrate the fuzzy approach. The fuzzy approach exhibits a more appropriate and flexible result compared to the traditional approach.
