A review of the optimization methods used in the design of type-2 fuzzy systems, which are relatively novel models of imprecision, is presented in this book. The fundamental focus of the book is based on the basic reasons of the need for optimizing type-2 fuzzy systems for different areas of application. Recently, bio-inspired methods have emerged as powerful optimization algorithms for solving complex problems. In the case of designing type-2 fuzzy systems for particular applications, the use of bio-inspired optimization methods have helped in the complex task of finding the appropriate parameter values and the right structure of the fuzzy systems. In this book, we review the application of genetic algorithms, particle swarm optimization and ant colony optimization, as three different paradigms that help in the design of optimal type-2 fuzzy systems. We also provide a comparison of results for the different optimization methods for the case of designing type-2 fuzzy systems.
