Abstract: Under emergency conditions, the demand for emergency supplies have time constraints, It is with great significance under conditions of the time window to study vehicle scheduling problem to reduce the loss. With time windows constraints for the distribution center vehicle scheduling problem, ant colony algorithm using the time window into the form of penalty function, be incorporated into the objective function, the established time to meet customer delivery requirements of the minimum cost of transport under the conditions of the vehicle scheduling model, solution of the model be proposed, Simulation analysis is taking with an example.
