Planification pour les fonderies de type sable : une méthode combinant optimisation stochastique et simulation

Sand foundries are faced with dimensioning and planning problems. In order to solve these problems, we propose an environment for planning help which allows to evaluate a planning and automatically determinates a planning. This environment is based on a coupling between stochastic algorithms, a simulation model and heuristics. It allows to work in a reduced state-space and permits to treat problems with very high combinatory. Performances of this environment are illustrated through examples, taken from sand foundries context which permits to evaluate the quality of the results.
