Advantages

Disadvantages

became obstacle to the verification of system realiability

Fuzzy reasoning mechanism cannot learn from their mistake

Eliminate borderline cases

allows for the modeling and include of contradiction in knowledge base

Increase the system autonomy

Inference Engine

Knowledge Based

Fuzzification

Defuzzification

The process of transformation crisp input values into linguistic values.

Converts the fuzzy values into crisp value

It transfers the fuzzy set obtained by the inference engine into a crisp valur

It stores IF-THAN rules providing by experts
