Les processus cognitifs dans les activités d'ordonnancement en environnement incertain

Abstract : Planning processes, especially, scheduling play a major role in work systems stability and efficiency. Scheduling is regarded as a complex problem; among complexity factors, uncertainty represent a central dimension. Although numerous automated tools or decision support systems have already been designed to help operators schedule their activities. The part played by said operators remains primordial. Paradoxically, few researches were concerned by the cognitive activity of the scheduler. This PhD thesis in human factors aims at studying those cognitive processes, with a specific interest in uncertainty management strategies.After exposing a scheduling situations typology and a method for activity analysis, we presented two scheduling situations with high uncertainty factors to study: organization of rounds in Road Freight Transports (RFT) and scheduling in Visiting Nurse Agencies (VNAs). This ecological approach allowed for a better understanding of the human aspects of scheduling and the detection of uncertainty management strategies. This work contributes to widen the debate around the optimisation of Man-Machine collaboration.
