Preface

In recent years, the number and variety of applications of fuzzy logic have increased consid‐ erably. Applications range from consumer products such as cameras, camcorders, washing machines, and microwave ovens to industrial process control, medical instrumentation, de‐ cision-support systems, portfolio selection, among others.

In this book, the theory and applications of fuzzy logic are highlighted by describing differ‐ ent aspects of fuzzy logic. The book starts with a simple but fundamental question and then evolutionary optimization methods are used to fine tune fuzzy logic parameters. The book ends with some practical research on the application of fuzzy logic to various fields of study from energy efficiency to solid waste landfill management.

I would like to thank all the authors and scholars for their precious contributions to this book. Special thanks go to IntechOpen and Author Service Manager Mrs. Marina Dusevic for their support and patience.
