This volume provides an overview of fuzzy logic and outlines how it can be applied to real-world problems in industry and business. Four main concepts of fuzziness are covered: fuzzy logic, the mathematical basis of fuzziness; fuzzy systems, used for estimation and process control; fuzzy decision-making, the language-oriented fuzzy system used in decision-making; and fuzzy cognitive maps, generalized fuzzy feedback used to improve and refine future decision-making. The book focuses on how these concepts can be put to use in a practical way, and includes illustrative programs on an accompanying disk to provide hands-on experience in fuzzy applications.
