🌍 Applications of Fuzzy Systems in Real Life
📌 What are Fuzzy Systems?
Fuzzy Systems are intelligent decision-making frameworks that operate on fuzzy logic principles, enabling them to handle vague, imprecise, and uncertain information using linguistic rules instead of precise mathematical models.
These systems are widely adopted across industries due to their simplicity, adaptability, and ability to model human-like reasoning.
✅ Why are Fuzzy Systems Used in Real Life?
• Real-world problems often lack sharp boundaries.
• Classical logic (crisp systems) fails to handle linguistic, ambiguous, or overlapping data.
• Fuzzy Systems allow “soft decision making”, just like humans do.
