Ushbu maqolada lokomotiv dizel dvigatelining texnik holatini noaniq mantiqiy xulosalashning adaptiv tizimi (ANFIS) yordamida baholash masalasi ko‘rib chiqiladi. Tadqiqot 2TE25KM seriyali lokomotivdan harakat parametrlarini nazorat qilish va diagnostika tizimi (MSU) yordamida olingan real ekspluatatsion ma’lumotlar asosida olib borildi. Ikkita diagnostik model ishlab chiqildi: moy bosimini prognozlash modeli hamda ishchi gazlar harorati bo‘yicha silindrlararo nomutanosiblikni prognozlash modeli. Har bir model uchun alohida-alohida Gauss va trapetsiyasimon a’zolik funksiyalari qo‘llanilib, ularning natijalari RMSE, MAE va korrelyatsiya koeffitsiyenti (R) ko‘rsatkichlari bo‘yicha taqqoslandi. Moy bosimi modelida R ning ikkala qiymati ham yuqori va deyarli bir xil bo‘ldi, biroq ishchi gazlar modelida trapetsiyasimon funksiya uchun R qiymati (R = 0,51) Gauss funksiyasiga (R = -0,03) qaraganda ancha barqaror ekanligi aniqlandi. Bu kichik hajmdagi shovqinli diagnostik ma’lumotlar bilan ishlashda trapetsiyasimon a’zolik funksiyalarining afzalligidan dalolat beradi.
