| چکیده | ||
| در این مطالعه دسته‌بندی گوجه فرنگی به کمک منطق فازی و تغییر در آن در شرایط مختلف نگهداری مورد مطالعه قرار گرفت. بدین منظور ویژگی‌های کیفی از قبیل رنگ، اندازه و سختی گوجه فرنگی اندازه‌گیری شد. دسته‌بندی نمونه‌ها توسط یک سامانه طراحی شده منطق فازی با قواعد فازی با نظر کارشناسان خبره مقایسه گردید. تجزیه و تحلیل حساسیت خروجی توابع عضویت به کمک آماره مربع کای مشخص شد. نتایج نشان داد که حساسیت دسته بندی نمونه‌های نگهداری شده در سردخانه از روز ششم با تغییر از دسته "درجه1" به "درجه2" رخ داد. برای نمونه‌های نگهداری شده در شرایط محیط این حساسیت از روز سوم با تغییر دسته‌بندی مشابه رخ داد. نتایج تاکید می‌نماید هرگونه عملیات فرآوری یا بازار رسانی پس از دسته‌بندی اولیه باید از لحاظ صرف زمان بگونه‌ای باشد که حاصل دسته‌بندی اولیه را دچار تغییر ننماید. | ||

| چکیده [English] | ||
| In the present study, classification of tomatoes by fuzzy logic and change in classification due to storage conditions were studied. In order to conduct the study, qualitative properties such as color, size and hardness of tomatoes were measured. Tomato samples were sorted by a deigned fuzzy logic system based on fuzzy rules, and compared with the experts. Sensitivity analysis of outputs of membership functions were tested by chi-square statistic. In cool room storage, sensitivity of membership functions started from six-day after storage with change from grade 1 to grade 2. For samples that kept at ambient temperature sensitivity started on third day after storage with the same change in sorted groups as previous tests. The results emphasized that any processing operation or marketing after initial sorting of tomatoes should spend time in a way that does not change the results of the initial classification. | ||
