基于综合物流的铁路货运能力优化研究

铁路货运能力优化研究对于铁路运输能力提升具有积极的意义.在对经典列车开行能力优化分析的基础上,综合考虑整体物流系统,以网络内列车运行总成本与货物在货运站的库存惩罚的差值最大为目标,考虑发车数量、流量守恒等约束,建立基于综合物流系统的铁路货运能力优化单目标线形规划模型,并根据模型特征,设计基于整数编码的遗传算法进行求解.

Study on Railway Freight Capacity Optimization based on Integrated Logistics

Railway freight capacity optimization plays a significant role in Tailway freight capacity improvement. Based on the analysis of classic freight capacity optimization and in light of the whole logistic s1ystem, a single objective linear pro- gramming model is proposed with objective aims to maximize the different value between the total cost of train operation on the network and inventory cost at freight station. Additionally, departure train number limit and flow conservation and so on are also considered as constraints in the model. Finally, according to model characteristics, a genetic algorithm based on integer coded is designed to solve the model.
