Dynamic vehicle routing problem(DVRP) is emerging topical issue for the vehicle routing problem, but its realtime
optimization still needs to be improved. Therefore, the mod nTSP strategy is proposed based on the flexible nTSP
strategy. And the competitive analysis of the new strategy shows the reason of the improvement. Finally, the simulation
results show that the new strategy can reduce the average distance between the adjacent customers on the routing of vehicle
while keeping the other system time constant, and the average customer system time can be reduced.
