Optimal Design of the Cross-docking in Distribution Networks: Heuristic Solution Approach

Cross-docking plays an importation role in distribution networks. In the recent years, a cross-docking design network problem is addressed as a new research area in logistics management. This paperpresents a new mathematical model for the location of cross-docking facilities and vehicle routingscheduling problems in the distribution networks. For this purpose, a two-phase mixed-integer programming (MIP) is formulated. Then, a new heuristic-based simulated annealing (SA) is developed for solving the proposed MIP model. Finally, the presented heuristic algorithm is subsequently testedon a number of small and large-scale instances. The computational results for different-sized instances illustrate that the proposed algorithm performs effectively in a reasonable time.
