Grading of agricultural products, especially fruits and vegetables, improves packaging, transportation and marketing processes, reduces losses, and leads to an added value of the product. It is therefore important that the appropriate technology is adopted for this purpose. In this study, performance of four onion sorting mechanism, namely sieving screen, fixed divergent rollers, expandable rollers with plate spacer and expandable roller with roller spacer were compared by both Analytical Hierarchy Process (AHP) and fuzzy analytical hierarchy process (FAHP). ? main criteria including proper grouping of onions, machine capacity, mechanical damages, machine portability, member of outlet groups, adjustment of outlet group size range, initial price and after-sales services were considered for determining the priority of onion sorters. The results showed that among the ? main criteria, the highest and lowest weights were allocated to mechanical damage and initial price, respectively. According to the results of the integration of different criteria and options, Both methods showing the same order determined that the expandable rollers with plate spacer with ?.??? (AHP) and ?.??? (FAHP) have the highest weight following by expandable roller with roller spacer with ?.??? (AHP) and ?.??? (FAHP), sieving screen with ?.??? (AHP) and ?.??? (FAHP) and fixed divergent rollers with ?.??? (AHP) and ?.??? (FAHP) respectively. In this way, expandable rollers with plate spacer, expandable roller with roller spacer, sieving screen and fixed divergent rollers were selected as the priority. These results showed that FAHP eliminating weak probabilities improved the decision-making ability.
