Computational intelligence with fuzzy logic for complex systems

Fuzzy logic is an innovative technology that enhances conventional system design with engineering expertise. The working of fuzzy logic becomes clear if one focuses on the working of present day computers. The working of present day computers is based on simple binary logic. Boolean logic is good for computing, but it does not work for imprecise values, since these computers normally solve problems by breaking them down into a series of binary decisions. Fuzzy logic allows the computers to assign numerical values that fall between "ones" and "zeroes", there is no clear border line between these values. Instead of statement being only true or false, fuzzy theory sets up condition as slow, medium, and fast. This paper deals with the state of art of fuzzy logic and with its advantages.
