The complement of a fuzzy set is denoted by Ā(x) and is defined with respect to the universal set X as follows: Ā(x) = 1- A(x) for all x ε X. Figure 4: Example of complement operation on a fuzzy set. 3. Intersections of fuzzy sets. Inter section of a fuzzy sets define how much of the element belongs to both sets.

Abstract The subject of this chapter is fuzzy sets and the basic issues related to them. The first section discusses concepts of sets: classic and fuzzy, and presents various ways of describing fuzzy sets. The second section is dedicated to t-norms, s-norms, and other terms associated with fuzzy sets. Subsequent sections describe the extension prin...
Similarly to classic sets, operations of product, sum, and complement are also estab-lished for fuzzy sets. Product and sum are defined by means of operators of t-norm and s-norm: μA B (x ) μA (x
When analyzing fuzzy sets (fuzzy relations) defined in universes of different dimen-sionality, sometimes there is a need to increase or reduce dimensionality of one of the sets (one of the relations). To increase or reduce dimensionality, operations of cylindrical extension and projection were defined [26]. Cylindrical extension of a fuzzy set A le...

This chapter reviews the fundamentals of basic fuzzy set theory initiated by Zadeh, which will be used throughout the remainder of this book. Starting with several basic definitions involving fuzzy sets, the extension principle of Zadeh is presented.
