Introduction An application of Electronic Commerce using Fuzzy Logic Inference system is presented in this final project. Implementation of a Paradigm for Intelligent Decision and Control; and also the Intelligent Design and Operation of Human-Computer interfaces [1]. The artificial technique used is Fuzzy Logic Inference and the software required execute the program is Matlab V.6.1. Analize User Characteristics Fuzzy Logic Inference User Profile.

Sugeno-type inference -- A type of fuzzy inference in which the consequent of each rule is a linear combination of the inputs. The output is a weighted linear combination of the consequents. The several defuzzification strategies are: centroid:centroid of area method bisector:bisector of area method mom: mean of maximum method som: smallest of maximum method lom:largest of maximum method
