Bulanyk mantyk sistemlerde, kelimelerin farkly insanlar için farkly anlamlarynyn olmasy, bilginin ayny görü?te olmayan uzman grubundan alynmasy, bulanyk mantyk sistemleri harekete geçiren ölçümlerin gürültülü olmasy gibi nedenlerden dolayy belirsizlikler vardyr. Bu makalede, bulanyk manty?yn yeni bir açylymy olan ve belirsizlikleri modelleyip etkisini azaltan tip-2 bulanyk mantyk ve tip-2 bulanyk küme i?lemlerine genel bir baky? sunulmu?tur. Amaç, tip-2 bulanyk mantyk teorik konularyny, tanymlamalary ve yapylan çaly?malary vurgulamaktadyr.

Fuzzy logic system have an uncertainty because of words mean different things to different people, data obtained from experts who don't all agree, measurements that activate the FLS are corrupted by noise. In this paper, we present a survey of operations on type-2 fuzzy set and type-2 fuzzy logic which is a new definition of fuzzy logic, model and minimize the effect of uncertainty. The main focus of this paper is on the theoretical topics, with descriptions of what they are, and what has been accomplished.
