Vehicle routing problem with time windows and fuzzy demands: an approach based on the possibility theory

International audienceIn this paper, the vehicle routing problem with time windows and fuzzy demands (VRPTWFD) is considered and a fuzzy recourse model based on the possibility theory is proposed. A stochastic simulation and a genetic algorithm (GA) are integrated to design a hybrid intelligent algorithm to solve the fuzzy version of a stochastic recourse model. Moreover, an adaptation of the Solomon's benchmark is proposed in order to assess the quality of the proposed approach
