An Evolutionary Algorithm with Distance Measure for the Split Delivery Capacitated Arc Routing Problem
Abstract
This chapter deals with the Split Delivery Capacitated Arc Routing Problem or SDCARP. Contrary to the classical Capacitated Arc Routing Problem or CARP, an edge may be serviced by more than one vehicle. An integer linear program, an insertion heuristic and a memetic algorithm with population management are proposed for this problem seldom studied. The algorithm calls an effective local search procedure, which contains new moves able to split demands. Compared to one of the best metaheuristics for the CARP, we show that splitting demands can bring important savings and reduce significantly the number of required vehicles.
