In this chapter we have collected together the basic ideas from fuzzy sets and fuzzy functions needed for the book. Any reader familiar with fuzzy sets, fuzzy numbers, the extension principle, a-cuts, interval arithmetic, possibility theory and fuzzy functions may go on to the rest of the book. A good general reference for fuzzy sets and fuzzy logic is , .
