摘要
针对ATO自动运行系统的准时性、停车精确性、舒适性和节能性四大性能指标的权重分配问题,采用层次分析法和马氏距离相结合的离线主客观分配法,以及模糊聚类法和粗糙集相结合的在线纯客观分配法,分别对测试线路上列车运行过程中各性能指标进行权重分配,根据分析结果得出,2种方法分配的权重下ATO均取得了良好的控车效果。
In the paper,the weight distribution problems of four performance indicators of ATO,that is punctuality,parking precision,comfort,and energy saving performance,are addressed and two methods are proposed to solve them.One is offline subjective and objective distribution method which combines hierarchical analysis process and the Mahalanobis distance,and the other is online objective weight distribution method which combines fuzzy clustering and rough sets.Each of the two methods was used to determine the weight of the performance indicators of the trains running in the test line and it was concluded based on the results of analysis that the ATO had obtained good control effects by using the weight distribution determined by the two methods.
