SKAI: a knowledge based environment for scheduling traction equipment and personnel K. Van Marcke & B. Tubbax Knowledge Technologies n.v., Spaarstraat 29, B-1000 Brussels ABSTRACT The paper presents SKAI, a knowledge based system to schedule traction equipment and train personnel developed for the Belgian railway company SNCB.
