In this article we will discuss about:- 1. Need of Ambiguity 2. Aspect of Ambiguity 3. Suitability of Fuzzy Logic. Need of Ambiguity: It is said that the binary logic which allows 'yes' or 'no' is due to Aristotle, an ancient Greek philosopher. He recognised the existence of what should be determined not either 'yes' or 'no'. This means that [...]
In this article we will discuss about:- 1. Introduction to Fuzzy Inference System 2. Architecture of a Fuzzy Inference System. Introduction to Fuzzy Inference System: Let us review inference in logic. It is based on principle of syllogism (deductive reasoning). Consider the statements: If A implies B If B implies C Infer- A implies C Now take a look at [...]
The following points highlight the four main applications of fuzzy logic. The applications are: 1. Fuzzy Expert Systems 2. Fuzzy Control 3. Fuzzy Data Bases and Information Retrievel Systems 4. Fuzzy Survey. Data bases associated with the real world problems are invariably contaminated with imprecision and inconsistency of data. Besides, the knowledge base is found to contain pieces of knowledge [...]
