    Scatter search for a real-life heterogeneous fleet vehicle routing problem with time windows and split deliveries in Brazil
    (2009-12-05) BELFIORE, P.; YOSHIZAKI, H. T. Y.
    In this paper, we consider a real-life heterogeneous fleet vehicle routing problem with time windows and split deliveries that occurs in a major Brazilian retail group. A single depot attends 519 stores of the group distributed in 11 Brazilian states. To find good solutions to this problem, we propose heuristics as initial solutions and a scatter search (SS) approach. Next, the produced solutions are compared with the routes actually covered by the company. Our results show that the total distribution cost can be reduced significantly when such methods are used. Experimental testing with benchmark instances is used to assess the merit of our proposed procedure. © 2008.
