The main aim of this tutorial is to educate a new generation of type-2 fuzzy systems researchers. The main audience of this tutorial will be graduate students, young researchers, engineers or researchers who would like to start working in the area of type-2 fuzzy systems. The tutorial will be a two part tutorial, where the first part of the tutorial (2 hours) will concentrate on the theoretical basis and definitions of type-2 fuzzy sets and systems while giving a complete coverage of interval type-2 fuzzy systems. The tutorial will use different means of simplifying and explaining the subject through different examples. The second part of the tutorial (3 hours) will be split into two parts addressing the practical aspects and the future directions of type-2 fuzzy systems. The practical aspects part of the tutorial will present the necessary algorithms needed to develop complete type-2 fuzzy systems applications. This part of the tutorial will present several applications of type-2 fuzzy systems. We will also explain when to use type-2 fuzzy systems and will guide the audience through the steps needed to design a type-2 fuzzy system. Several interactive examples will be presented to the audience to make sure that the audience can start to confidently design type-2 fuzzy systems. The future directions part will explore future directions of type-2 fuzzy systems explaining what the ¡®hot topics¡¯ are thus allowing, for example, PhD students to see where they might take their work. It will include a short overview of the progress with generalized type-2 fuzzy systems.



Jerry M. Mendel received the Ph.D. degree in electrical engineering from the Polytechnic Institute of Brooklyn, Brooklyn, NY.
