Evaluation of essential properties of impregnating agents for preserving wood by AHP method in fuzzy environment

Abstract

In this study, the essential properties of the impregnating agents for preserving wood were evaluated using analytic hierarchy process (AHP) method in fuzzy environment. Firstly, an AHP has been established and a questionnaire has been prepared of all criteria mentioned in the process. The questionnaire questions were answered by experts in the field. The answers were transformed into fuzzy numbers and all responses were evaluated in accordance with Buckley method. Fuzzy and normalized weights of all major and sub-criteria were calculated. According to the calculations made using this method, the first expected property impregnating agents for preserving wood was found to be the effectiveness parameter. It was followed by the eco-friendly, economic, permanent and reliable main criteria. The expected properties from an impregnation agent may vary according to the classes use and used wood commodity. This study showed that the fuzzy AHP method can be used in the impregnation industry as well as many engineering disciplines.
