Model and Algorithm for Wagons' Placing-In and Taking-Out Problem in Railway Station

Taking the locomotive running time between goods operation sites as weights, wagons' placing-in and taking-out problems can be regarded as a single machine scheduling problem 1| pij | Cij, which can be transformed into a shortest cycle problem of Hamilton graph whose relaxation problem is assignment problem. Firstly, the authors use a Hungarian algorithm to calculate the optimal solution of the assignment problem. Then, the authors provide a Broken-circle and Connection method to find the available order of placing-in and taking-out wagons. The complexity of the algorithm is O(n²). Extensive problems -- such as placing-in and transferring combined or taking-out and transferring combined, placing-in and taking-out combined, placing-in, transferring and taking-out combined -- can also be resolved with the modified model and algorithm. Finally, an instance is given to illustrate the model and the algorithm's reliability and efficiency.
