Abstract :
Transportation sector generates a considerable part of each nationʹs gross
domestic product and considered among the largest consumers of oil products in
the world. This paper proposes a heuristic method for the vehicle routing
problem with hard time windows while incorporating the costs of fuel, driver,
and vehicle. The proposed heuristic uses a novel speed optimization algorithm
to reach its objectives. Performance of the proposed algorithm is validated by
comparing its results with the results of the exact method and differential
evaluation algorithm for small-scale problems. For large-scale problems, the
results of the proposed algorithm are compared with those obtained from the
differential evaluation algorithm. Overall, results indicate the good performance
of the proposed heuristic algorithm.
