Why fuzzy logic is used?

Here are some reasons why fuzzy logic is used:

1. **Handling Uncertainty:** In real-world scenarios, information can be vague or imprecise. Fuzzy logic allows systems to make decisions based on degrees of truth rather than absolute values.

2. **Mimicking Human Reasoning:** Fuzzy logic can model human reasoning more closely by handling concepts that are not black-and-white, such as "somewhat tall" or "a little bit hot."

3. **Flexibility:** It provides a way to deal with a range of values and uncertainty, making it useful for complex systems where precise measurements are difficult or impractical.

4. **Simplifying Design:** Fuzzy logic systems can simplify the design of control systems and decision-making processes by allowing for rules that are expressed in natural language, which can be more intuitive.

5. **Adaptability:** Fuzzy logic systems can be adapted and tuned more easily than traditional systems, which often require precise mathematical modeling.

Overall, fuzzy logic is used in various applications like control systems, decision-making processes, and pattern recognition, where traditional binary logic might fall short.
