2. FUZZY LOGIC
Fuzzy logic or Fuzzy systems are logical systems for standardisation and formalisation of approximate
reasoning. It is similar to human decision making with an ability to produce exact and accurate solutions from
certain or even approximate information and data. The reasoning in fuzzy logic is similar to human reasoning.
Fuzzy logic is the way like which human brain works, and we can use this technology in machines so that they
can perform somewhat like humans. Fuzzification provides superior expressive power, higher generality and an
improved capability to model complex problems at low or moderate solution cost. Fuzzy logic allows a
particular level of ambiguity throughout an analysis. Because this ambiguity can specify available information
