The algorithm deals with a specific representation of the solution, enabling the effective application of the shaking and local search procedures. System of neighborhoods changes the assignment ordering for an increasing number of items, while local search procedure tries to locally improve the solution by swapping the assignment ordering for pairs of items. Numerical experiments are performed on instances known in the literature. Computational results show that the proposed VNS achieves all optimal solutions for smaller instances, while for larger instances it finds rather better solutions than previously known method. © 2012 Elsevier B.V. |
