Fuzzy logic, also known as approximate reasoning, is an expansion of set theory originated in the 1960s by Lotfi Zadeh. It has been applied successfully in many areas, including control systems. This paper defines key concepts of fuzzy logic, shows examples of fuzzy logic in life and in real-world applications, shows how fuzzy logic can be applied to computer performance work to simplify and speed analysis and reporting, and shows a simple example of program code which implements fuzzy logic. Examples are based on MS-Windows®, but the principles should be applicable to other operating systems.
