Routing Optimization of Container Yard Crane

The operating efficiency of work machines in container yards can significantly affect the operating costs and even the competitiveness level of the port. Therefore, this article studies on the routing optimization problem of gantry cranes from the perspective of the work machines. The routing optimization model of the gantry crane is established with the objective function of the shortest path and the constraints of loading and unloading requirements for quay cranes. Then a practical example is solved by an improved simulated annealing. The feasibility of model and algorithm is proved with the obtained good convergence results.
