PROPOSITION D'UN MODELE POUR L'ORDONNANCEMENT ET LA PLANIFICATION REACTIVE : APPLICATION A LA MAINTENANCE FERROVIAIRE

Abstract : The aim of this work is to measure the performance of a production control system. We focus on the problematic of control system in an environment composed of several decision centers, taking into account reaction delays. When an unexpected event is detected by a decision center, some modifications of the schedule required by this decision center may induce consequences on tasks under the control of other decision centers, because there exist some constraints between the jobs controlled by different decision centers. Each modification during the execution of a task should be submitted to the approval of each concerned decision center. The coordination between these decision centers implies a reaction delay between all of them. But, the suggested modifications may not be compatible with these reaction delays. This is why we present a control model for reactive scheduling, including reaction delays between decision centers. This model leads to a formal definition of reactivity being used to the industrial case of the high-speed train (TGV) maintenance at the French railway company (SNCF).
