铁路行包运输运能分配方案研究

Study on Distribution of Railway Luggage & Parcel Transportation Capacity

铁路行包货物具有批量小、到站分散、种类繁多的特点。在实际运输过程中,由于行包到达的不均衡和运输组织的复杂性,往往不能保证行包在车站的集中到发。对于行包作业量小的车站,很容易导致人力资源的浪费,带来运营管理成本的增加。针对这样的情况,以作业量小的车站行包尽可能集中到发为优化目标,建立了行包运输方案的线性混合整数规划模型。实例计算表明,通过该模型的求解,可以保证优先把运能分配给行包办理量小的车站,从而达到降低铁路运营管理成本的目的。

Railway luggageparcel has the characteristics of small volume, dispersion in arrival station and diversified categories. During the actual transportation, because of unbalanced luggageparcel arrival and departure and complex transport organization, the centralized arrival and departure of luggage parcel in station usually cannot be ensured. For stations with small volume, their labor resource will be easily wasted, and the operational management cost will increase as a result. Targeting with above status, taking centralized luggageparcel arrival and departure in the stations with small volume as the optimization objective, the linear mixed integer programming model of luggageparcel transport was established. The calculation of actual example shows that luggageparcel could arrive and depart at stations with small volume on a relatively high dgree of concentration, so as to reduce railway operational management cost.
