An overview of GPSYS, an intelligent linear and integer goal programming system is presented in this paper. The intelligent goal programming system is one which is designed to allow a non-specialist access to, and clear understanding of, goal programming solution and analysis techniques. GPSYS is equipped with GP speed up techniques and analysis tools such as Pareto detection and restoration, normalisation, automated lexicographic redundancy checking and an interactive facility.
