Eléments de flexibilité des systèmes de workflow pour la définition et l'exécution de procédés coopératifs

Abstract : In order to improve the effectiveness of workflow systems for cooperative work we propose a model of cooperative workflow which allows a flexible process execution. The control flow flexibility is based on the concept of anticipation that allows an activity to start its execution even if its activation conditions are not yet satisfied. Anticipation increases parallelism between activities and improves their execution quality by supporting rapid feedback. The flexible data exchange between activities is allowed by encapsulating activities in cooperative transactions. This activity model surpasses the "black box" activity model, considered by traditional workflows, while maintaining the necessary level of control. The second contribution of this thesis consists in a technique and suited tools for exceptions analysis, prediction and prevention. These tools use data mining techniques that are applied to process execution data stocked in a data warehouse.
