Optimization Model and Algorithm for Collaborative Assignment Between Cargo Products and Station Resources

货运产品与车站资源协同分配研究,对于提升铁路运输的经济效益、优化铁路基础设施布局具有重要意义。首先阐述货运产品与车站资源分配之间的内在联系,以车站分配中的多分配模式为例,综合考虑技术站扩能及费用等相关因素,以铁路运输收益最大化为优化目标,构建铁路货运产品与车站资源协同分配优化模型。根据模型多决策变量的特点,采用和声搜索算法与基于反馈的免疫克隆算法进行求解,最后以某一条繁忙干线为例验证模型及算法的性能,结果表明模型和算法具有较好的适用性。

Research on collaborative assignment between cargo products and station resources is beneficial to the optimization of the layout of railway infrastructure and to the improvement of the economic benefits of railway transportation. The internal relation between cargo products and station resources assignment was analyzed. Based on the analysis, with the multi-mode allocation as an example, using the maximization of transportation revenue as model objective, the collaborative assignment model between cargo products and station resources was built, considering the factors of capacity expansion and transformation cost of the technical station. Based on the characteristics of the multi-decision variables of the model, the harmony search algorithm and feedback- based immune clone algorithm were used to solve this model. At last one railway trunk line was used as a numerical example to verify the model and algorithms. The results showed good applicability of the model and algorithms.
