编组站运输能力自动计算系统的研究

本文介绍编组站运输能力自动计算系统,该系统采用数据挖掘技术—决策树C4.5算法,从编组站综合自动化(SAM)系统数据库丰富的数据信息中自动筛选、汇总能力计算所需数据,自动建立符合当前编组站实际情况的能力自动计算体系,按照预先设置的能力计算单位时间,自动计算编组站全站能力或单项设备能力.最终通过人机界面以图表方式显示能力计算及查询结果,为编组站技术装备的管理和运营组织方式的调整提供更加丰富、客观的数据依据.

Research on Automatic Calculation System for transport capacity of marshalling yard

This thesis introduced the Automatic Calculation System for transport capacity of the marshalling yard.The DM technology that was the decision tree C4.5 Algorithm was used to screen and collect the data used in capacity calculation from abundant data information in the database of the Synthetic Automation of Marshalling Yard（SAM） System.It was built the automatic calculation system which conformed to the current actual situation of the marshalling station automatically,automatically calculated the total capacity of the marshalling station or single equipment capacity according to the preset capacity calculating unit time.Finally the capacity calculation and the query results were displayed in charts through friendly man-machine interface.It was provided richer and more objective data for the management of technical equipment and the adjustment of the operational organization of marshalling station.
