Interval Type-2 Fuzzy Sets (IT2FS) 
Interval Type-2 Fuzzy Logic System (IT2FLS)
由於已經很多大師級人物用英文發表了很多論文,所以在這邊我以中文為主 !!!
首先請一定要有心裡準備把 Prof. Jerry Mendel 的論文都讀過一遍


讓我們從這篇開始吧 ! Mendel, J. M., "Type-2 Fuzzy Sets and Systems: an Overview," IEEE Computational Intelligence Magazine, Vol. 2, pp. 20-29, February 2007.
