Comparison between Definitive and Fuzzy decision models and their application in appointing the priority of agricultural production Combination

In this paper two technics of, definitive analytical hierarchy process and Fuzzy analytical hierarchy process are compared. By this means a practical instance of fuzzy and definitive analytical hierarchy process is proposed for defining the priority of production of crops in farms of babolsar city. In a definitive approach‚ by the use of Eigen vector and the expert choice software‚ the final weights are calculated for each matrix. In the fuzzy approach‚ by the use of young changes extend analysis method‚ in which the used Triangular numbers are fuzzy, the final weights are calculated. the purpose is to define priority of producing rice‚ wheat and canola‚ with considering two quantitative criterions of benefit and efficiency per hectare plus two qualitative criterions of expertise and buying guaranty from the view point of agriculture sector reporters. Results indicate that in both approaches of fuzzy and definitive analytical hierarchy process‚ the importance of rice is more than canola and wheat. But fuzzy analytical hierarchy process makes the decision maker reach a more trusted final priority appointment (because of more difference in the weights).
