Research On Reasonable Utilization Scheme Of Coal Transport Channel Capacity Under Large Logistics Model

Freight heavy load is one of the important directions of China's railway development.Due to the uneven distribution of coal resources in China,the basic pattern of"North-to-South Coal Transport and West-to-East Coal Transport" has formed on transport,making the development of heavy-load railways a transportation demand and inevitable trend.However,due to the equipment conditions,freight demand,and the particularity of the organization of the traffic flow,the heavy-haul railway transportation organization is very different from the general route.In recent years,with the relative decline in the coal transportation market and the gradual advancement of the direction of railway logistics,especially the growth in the demand for multi-category cargo transportation,great challenges have been put on the use of the capacity of heavy-load lines,which has caused changes in the utilization of existing transport capacity.It's more complicated.In this case,it is of great significance to analyze the ability influencing laws without the configuration of transportation resources and the composition of train flow,and to formulate a reasonable utilization plan for different capacity utilization situations and cargo flow organization requirements.In view of the above situation,this paper starts with the actual operation of China's existing single-line heavy-duty freight dedicated line,and studies the issues related to its ability to pass through the transportation organization.First,on the basis of summarizing and rationalizing the operation status of existing heavy-duty freight special lines,the factors affecting capacity are analyzed from the aspects of line conditions,equipment types,and transport organization,and the extraction of key points for specific research is realized;Using simulation methods to study the effect of the use of point-line system capabilities and the optimization scheme for single-line heavy-duty use:? In combination with the heavy-haul line transport organization model and actual simulation requirements,the model of train operation control simulation framework based on Agent and CA is proposed,the interaction mechanism is defined,and the constraints between train agents are further refined,and a heavy load is constructed.The semi-autonomous railway block control of the following vehicle operation simulation model provides the theoretical basis and data source for the following simulation and simulation of train operation process of heavy-haul railway trains.? Based on cellular automata,a simulation model of railroad heavy-duty train operation organization was established,and a railway dotted line system was taken as the research object,aiming at the correlation between the parameters of train operation organization and the different train ratios,different arrival strengths,etc.The relationship was simulated and the simulation results show that the simulation method is reliable,which provides a scientific basis for optimizing the organization of train load flow in the railway.Finally,based on the above theoretical research results,the Baoshen North Line's ability to use a reasonable program is studied,specifically including:Under the conditions of capacity constraints basic program,parallel painting and clustering organization program plan simulation;Under the situation of capacity redundancy Heavy-duty train rapid return or fixed-point and fixed-line organization program operation diagram simulation;Different sunroof opening model of the ability to use the impact of operation diagram simulation.
