Abstract:
In this system, decision making for the type of coffee drink is implemented by using fuzzy logic. Five types of coffee drinks: coffee with soft instants, coffee with normal instants, coffee latte, coffee espresso and coffee macchiato are considered. There are three instants to mix: milk, fresh milk and coffee powder. Fuzzy decision making system determine the type of coffee drinks according to the ratio of instants. The fuzzy control system consists of three main parts. There are fuzzification, inference engine and defuzzification. Center of Gravity (COG) defuzzification method is used in this system. This paper is implemented by using C# programming language.
