DÉJÀ VU — A reusable framework for the construction of intelligent interactive schedulers

Abstract

We describe the techniques of the DEJA VU Scheduling Class Library to achieve a library of reusable and extendible c1asses for the construction of interactive scheduling systems. The constructed systems shall be efficient and user centered. We describe abstract scheduling objects, constraints between them, and potential user interactions with the system. A first scheduling system was developed for the steel plant of Böhler Kapfenberg. We demonstrate which extensions were necessary and show prototypical examples from the graphical user interface.
