Following FLINS '94 and FLINS '96, the first and second International Workshops on Fuzzy Logic and Intelligent Technologies in Nuclear Science, FLINS '98 covers recent developments, both of a foundational and applicational character, in the fields of intelligent techniques such as fuzzy logic, neural networks, genetic algorithms, robotics, man-machine interface and decision-support systems within nuclear science and related research fields.This volume clearly shows the leading role of FLINS as a forum for the applications of new intelligent techniques in the nuclear domain.
