Abstract

Decision making in the real world is based on mostly vague and imprecise data. Some of the important questions that have haunted control engineers are: Is it necessary to know a detailed mathematical model of the system in order to control it effectively? Is it possible to make a controller learn as to how to control the plant effectively? How does a human controller act in such circumstances where the data is vague and incomplete? Fuzzy logic addresses these problems by presenting meaning to this imprecise information so that they can be used effectively by computers. In this paper an E-business application of fuzzy system models have been given. The authors have designed a Fuzzy logic controller by using all the principal design elements such as Fuzzification strategies, Knowledge base, Rule-base, Decision-making logic and Defuzzification strategies. The authors have used a company`s database and transformed it into fuzzy environment. The designed Fuzzy controller matches the query up to an acceptable value.
