Advantages of Fuzzy logic
Mathematical concepts within fuzzy reasoning are very simple.
You can modify a FLS by just adding or deleting rules due to flexibility of fuzzy logic.
Fuzzy logic is a solution to complex problems in all fields of life, including medicine, as it resembles human reasoning and decision making.
Disadvantages of Fuzzy Logic
There is no systematic approach to fuzzy system designing.
They are understandable only when simple.
They are suitable for the problems which do not need high accuracy.
