Technology has now progressed to the point that intelligent systems are
replacing humans in the decision making processes as well as aiding in the
solution of very complex problems. In many cases intelligent systems are already
outperforming human activities. Artificial neural networks are not only capable
of learning how to classify patterns, such images or sequence of events, but
they can also effectively model complex nonlinear systems. Their ability to
classify sequences of events is probably more popular in industrial applications
where there is an inherent need to model nonlinear system behavior. Fuzzy
systems have similar applications. Their main advantage is their simplicity and
ease of implementation. Various
