In this paper we present a method for modeling and managing various constraints encountered in task scheduling problems. Our approach aims at characterizing feasible schedules through the analysis of the set of constraints and their interaction, regardless to any optimization criteria. This analysis is achieved by a constraint propagation process on a(More)
Since the last decade, hard combinatorial problems such as scheduling have been the target of many approaches combining Operations Research and Artificial Intelligence techniques, focussed on constraint satisfaction as a general paradigm for representing and solving efficiently such problems (Van Hentenryck 89). Amongst these approaches, the so-called(More)
This paper proposes a method which assists the firms for cooperating in make-to-order production. More precisely, the operational decision levels of manufacturing companies are considered : the forecast scheduling and the real-time scheduling. The method organizes a production process which is distributed over several companies, by tightening the production(More)
