An overview of fuzzy logic

In a very simple term, fuzzy logic allows situations or problems to be described and processed in linguistic terms such as “hot” or “heavy” instead of precise numeric values such as “140 degrees” or “180 kg”. Fuzzy logic, in essence, allows one to view problems from a higher linguistic level, thereby enabling less complex problems to be solved more efficiently, and extremely large and complex problems to be solved at all. Because of the many advantages of such a linguistic system, the areas of application of fuzzy logic have spread from consumer electronics to industrial control, information processing, financial analysis and much more in just the past few years
