Exactly 50 years ago, in 1965, Lotfi A. Zadeh published a seminal paper 1 that started the field of fuzzy sets and systems. Since then, there have been thousands of efficient practical applications of fuzzy techniques (see, e.g., Refs. 2 and 3 and references therein). No matter how great an idea, its practical applications are rarely straightforward and easy: There are challenges to overcome and choices to make. For complex practical problems, there are usually so many possible choices that it is not possible to find the right choice by an empirical trial and error, we need a theoretical guidance. From this viewpoint, fuzzy applications are no exception: fuzzy theory is indeed behind many current successful applications of fuzzy techniques. Practical needs regularly generate new theoretical challenges and inspire new results in fuzzy theory—results that lead to new successful applications.
