fuzzy logic Himpunan fuzzy Subset: Complement: Union: Intersection:
Himpunan fuzzy fuzzy logic Union mAB(x) = max(mA(x), mB(x)) Intersection mAB(x) = min(mA(x), mB(x)) Complementation mU-A(x) = 1 -mA(x)

Metode Sugeno fuzzy logic Untuk mendapatkan output, diperlukan 4 tahapan: Pembentukan himpunan fuzzy Aplikasi fungsi implikasi (aturan) Komposisi aturan Penegasan (defuzzyfikasi)
Metode Sugeno fuzzy logic Pembentukan himpunan fuzzy Variabel dibagi menjadi beberapa himpunan fuzzy (membership)
Metode Sugeno fuzzy logic Aplikasi fungsi implikasi (aturan) Yang digunakan adalah min (aturannya menggunakan AND) Contoh: IF minum banyak AND makan banyak THEN perut kenyang sekali
Metode Sugeno fuzzy logic Komposisi aturan Yang digunakan adalah max, dari beberapa aturan yang ada jika menggunakan MAX berarti di OR kan (keseluruhan aturan)
Metode Sugeno fuzzy logic Defuzzyfikasi Dengan menggunakan nilai membership masukan dan nilai membership keluaran sebagai berikut: Nilai keluaran= jumlah (membership masukan * membership keluaran ) / (membership masukan )
