Introduction to Fuzzy Systems

Fuzzy logic since its conception in 1965 [11] has been used in various areas of science, economics, manufacturing, medicine etc [1, 2, 3, 4, 7, 8, 9]. It constitutes, along with other methods such as neural networks or evolutionary algorithms, the idea of soft computing [5]. Fuzzy sets used in fuzzy rules can be a tool to model linguistic values like “small” or “high” [12]. This chapter presents basic definitions of fuzzy logic and fuzzy systems based on [10].
