两种集结模式对编组站解体系统的经济比较分析
|
摘要
分析货车在编组站解体系统的作业规律,建立解体系统排队模型.分析定时、定编集结模式对下游区段站解体系统相关经济指标的影响,应用补充变量法得到两种集结模式货车在下游区段站解体系统的平均停留时间公式.以山海关编组站车流为例,计算两种集结模式在解体系统的相关经济效益值,得到结论:定时集结相比定编集结节省的货车时间成本远大于其消耗的调车机车小时成本,具有较强的经济优越性;在求解两种集结模式经济适用性时,有必要考虑对下游区段站解体系统的影响,从而得到较为精确的经济适用条件,为实际工作提供理论基础.
The queueing models are established based on the analysis of operating rules of cars in classification system of marshalling yard. Fixed time and full- shaft assembly modes' effects on related economic indicators of the classification system of downstream district station are analysis, and the formulas of the average residence time in the classification system of the next marshalling yard are obtained according to the supplementary variable method. The car flows of Shanhaiguan Marshalling Station are took as an example, related economic values in classification system of two assembly modes are calculated. It can get the conclusions: the saving time costs of the fixed time assembly mode are bigger than the saving switcher hour costs of the full- shaft assembly mode; it is necessary to consider two assembly modes effects on downstream district station when solving the economic applicability. Then it can get the exact economic applicable conditions to provide theoretical basis for actual work.
