  2. Pengertian Fuzzy Logic • Sepertihalnyahimpunanbiasadanhimpunan fuzzy, makateorilogika fuzzy pun dapatdikembangkanserupadenganteorihimpunan fuzzy. Jikapadalogikabiasanilaikebenaransuatuproposisi/pernyataanhanyaadaduamacamyaitu 1 = benardan 0 = salahmakadalam fuzzy logic nilaikebenaran bias diperluasdenganbilangandiantara 0 dan 1.

  3. Pengertian Fuzzy Logic (2) • Salahsatucontoh fuzzy logic adalahdenganmenambahkannilaikebenaran ½ disampingnilaikebenaran 0 dan 1. • Jika 1=benar, 0=salahmaka ½ dapatdiartikansbgi ‘tidakpasti’/ mengandungkebenaran 50% dankesalahan 50%.

  4. Pengertian Fuzzy Logic (3) • LUKASIEWICZ FUZZY LOGIC : Lukasiewiczmengembangkansuatubentuklogika fuzzy untuk operator logikakomplemen, dan, atau, implikasidanbiimplikasiuntuk fuzzy logic dgntiganilaikebenaran 1, ½ dan 0.

  5. Operasi Fuzzy Logic (1) • OPERASI FUZZY LOGIC: SesuaidenganpengembanganLukasiewiczmakaoperasi-operasilogika fuzzy didefinisikansebagaiberikut:

  7. Operasi Fuzzy Logic (3) • TABEL KEBENARAN FUZZY LOGIC : Dari operasiLukasiewicz fuzzy logic tersebutmkdiperolehtabelkebenaranuntukoperasidan, atau, implikasidanbiimplikasidiperolehsebagaiberikut:

  8. Operasi Fuzzy Logic (4) • a b a’  v  • 0 0 1 0 0 1 1 • 0 1/2 1 0 1/2 1 1/2 • 0 1 1 0 1 1 0 • 1/2 0 1/2 0 1/2 1/2 1/2 • 1/2 1/2 1/2 1/2 1/2 1 1 • 1/2 1 1/2 1/2 1 1 1/2 • 1 0 0 0 1 0 0 • 1 1/2 0 1/2 1 1/2 1/2 • 1 1 0 1 1 1 1

  9. Operasi Fuzzy Logic (5) • LOGICAL EQUIVALENCE DUA PROPOSISI FUZZY : Duaproposisipada fuzzy logic adalah logical equivalence bilakeduanyamemilikitabelkebenaranygsama. Biladuaproposisi p dan q logical equivalence makaditulis p  q atau p = q.
