基于改进BSA的铁路危险货物办理站点整合优化

铁路危险货物办理站点作为铁路危险货物运输基础设施之一,其选址布局、建设规模和职能分工的合理性对于提高铁路危险货物运输效率、满足运输需求和环境风险控制目标都至关重要.为了有效解决铁路危险货物办理站点整合优化的多目标选址-分派模型组合方案规模庞大、计算困难的问题,采用了改进双层模拟退火算法对此问题进行优化.算例结果显示,该算法具有收敛速度快、运行稳定的特点,能够有效解决相关问题.

Integrated Optimization of Railway Dangerous Goods Stations Based on Improved BSA

As one of the railway dangerous goods transportation basic infrastructure, the location selection, construction scale and functional division reasonability of railway dangerous goods stations are important to improve the railway dangerous goods transport efficiency, satisfy transportation requirements and control environmental risk. In order to solve the large-scale portfolio alternatives and the difficult calculation effectively of railway dangerous goods stations integrated optimization multi-objective location-allocation model, a improved bi-level simulated annealing algorithm was used to optimize this issue. The simulation results show that this method draws fast convergence rate and stable, can effectively solve related problems.
