Des fourmis pour le problème d'ordonnancement de voitures

The car sequencing problem involves scheduling cars along an assembly line while satisfying capacity constraints. In this paper, we describe an Ant Colony Optimization (ACO) algorithm for solving this problem, and we propose two complementary pheromone structures for this algorithm : the rst one aims at learning good sub-sequences of cars, whereas the second one aims at learning "critical" cars...
