Research on optimization configuration method of railway dangerous goods stations and sidings

The reasonable configuration for railway dangerous goods stations is a complicated engineering system,dealing with the demand pattern,stations location,area planning,environmental protection,stations business functions and division and connection with other modes of transportation.The disadvantages of integrated optimization model of railway dangerous goods stations were discussed.The conditions of present railway dangerous goods stations and sidings were generaled considered,makes multi-criteria decision evaluation was conduded to reject railway dangerous goods stations and sidings which need to be optimized allocation,then the comprehensive utility evaluation of transportation demanders' selection about stations and sidings was taken.Based on invest cost,environmental risk,transportation utility and area fairness,railway dangerous goods stations optimization configuration model was constructed to effectively solve the complex factors,large scale,multi-level problems of railway dangerous goods stations and sidings optimization configuration model which has multi-stations and sidings,multi-demand,multi-area,multi-objective.Finally,the multi-objective genetic algorithm of decomposition-coordination for large-scale system was put forward to solve the model.
