The traditional vehicle routing problem with time windows (VRPTW) is expanded to the situation, where the time window is replaced by fuzzy due time which can represent the preferences of the customers. After asimple description of the fuzzy dial-a-ride problem, a multi-objective mathematical model for the problem is built up. Then, an insertion heuristic-based hybrid genetic algorithm is proposed to this kind of problem. In this algorithm, the modified push-bump-throw procedure is employed to handle the fuz...
