Coordination decision optimization for wagon-flow allocating and shunting locomotive utilization in railway marshalling station

The coordination decision problem of train wagon-flow allocating and shunting locomotive utilization is described using mathematics optimization method.The coordination decision model is established taking the full load train to the largest counts as goal,and adopts improving genetic algorithm to solve.According to the characteristic of train sorting,the natural number code and splitting up serial number matrix are adopted.The ague selection rules and limited individual variation are used to decrease randomness that genetic algorithm brings,and make the population after dissociation can face high fit in direction evolution.Taking some marshalling station as an example to simulate,the result proves that this algorithm can converge to satisfactory solution within shorter time.
