Using Fuzzy Delphi Method in Analytic Hierarchy Process to Select Optimum Maintenance Strategy

In this paper, a new approach which applies fuzzy Delphi method in analytic hierarchy process (AHP) method is proposed to select optimum maintenance strategy. This approach is designed based on representation of pair wise comparisons in AHP with fuzzy numbers. Fuzzy Delphi method is applied for the assessment of pair wise comparisons, considering the expert’s opinion. Using this method, both tangible and intangible goals dealing with the selection problem are considered. Fuzzy Delphi method generates L-R fuzzy number which can measure more adequate information about the nature of opinions. Yager ranking method is used as a transformation method for fuzzy numbers in the selection problem. Finally, through a heuristic algorithm, the main steps of the proposed method are presented.
