Abstract : We consider single machine scheduling problem with dynamic job arrivals and total weighted tardiness and makespan as objective functions. The machine is subjected to disruptions related to late raw material arrivals and machine breakdowns. We propose a proactive-reactive approach to deal with possible perturbations. In the proactive phase, instead of providing only one schedule to the decision maker, we present a set of predictive schedules. This set is characterized by a partial order of jobs and a type of associated schedules, here semi-active schedules. This allows to dispose some flexibility in job sequencing and flexibility in time that can be used on-line by the reactive algorithm to hedge against unforeseen disruptions. We conduct computational experiments which prove that our approach outperforms predictive-reactive approach particularly for disruptions with low to medium amplitude. || Nous considérons un problème d'ordonnancement à une machine avec arrivée dynamique des travaux. Les critères retenus sont la somme des retards et la durée totale. La machine est soumise à des perturbations dues à l'arrivée des composants et à des pannes.
