This paper proposes a hybrid heuristic algorithm combing variable neighborhood descent search withgenetic algorithm ( GA_VND) to solve vehicle routing problem with simultaneous delivery and pickup. By theuse of the initial populations generated randomly,the weak feasible solutions are produced by the crossoverand mutation operators of genetic algorithm. And then,the best of them was selected as initial solution of vari-able neighborhood descent algorithm. Finally,in the process of the variable neighborhood descent search, twodifferent neighborhood structures are used to search the locally optimal solution. The simulation results showthat GA_VND can update 8 better solutions in the 54 best known solutions,which illustrates that GA_VND isan effective method for vehicle routing problem with simultaneous delivery and pickup.
