Fuzzy Logic's advantages

This is fuzzy logic's advantages, I find it from a website.

1. Formalise and simulate the expertise of an operator or designer in process control and tuning
2. Provide a simple answer for processes which are difficult to model
3. Continually take into account cases or exceptions of different kinds, and progressively incorporate them into the expertise
4. Take into account several variables and perform “weighted merging” of influencing into variables
