Abstract:

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.

Key words: railway transportation, average residence time, queuing theory, classification system, fixed time accumulation, full-shaft accumulation
