3. Fuzzy logic systems
– Rule-based technology that represents imprecision used in linguistic (ภาษา
พูด)categories (e.g., “cold,” “cool”) by creating rules that use approximate
values
– Describe a particular phenomenon or process linguistically and then
represent that description in a small number of flexible rules
– Provides solutions to problems requiring expertise that is difficult to
represent with IF-THEN rules
– Example: temperature control in an air conditioner
