  6. Vagueness and fuzzy • Vagueness (Russel 1923) • Einstein (1937) • “As far as the laws of mathematics refer to reality, they are not certain, and as far as they are certain, they do not refer to reality” • Fuzzy logic invention: • Lotfi Zadeh (1965), although the ideas can be traced back to earlier works (1962…) • Zadeh (1968), fuzzy algorithms • Zadeh (1970), fuzzy decision making • Zadeh (1973), Principle of incompatibility. • Zadeh (1973), fuzzy control

  7. Fuzzy History • Fuzzy follow up: • Mamdani, first practical demonstration (1974 ) • Applying Fuzzy Logic for controller of steam engine • First fuzzy controller, Holmblad 1978. • First commercial applications in 1981. • Establishing of International Fuzzy System Association (IFSA). (1984) • In 1994, Japan exported products worth $35 billion that use fuzzy logic !
