Fuzzy logic delivers aids for decision-making if connections and facts are only approximately known and has been used with increasing success in numerous application areas (e.g., control engineering, vehicle technology, robot technology, consumer products, business administration, sample reconnaissance) within the last decades. More and more, fuzzy logic is becoming an important tool for system developers.
With the use of fuzzy logic, processes with imprecise or qualitative data can be modeled. Vague values (such as hot/warm/cold) or notions like probable/improbable can be introduced into the simulation. Numerous processes which are difficult to describe with only conventional methods can thus be represented practically and elegantly.
