Description

Technical Field

[0001] This invention relates to the field of heavy-haul railway technology, and more specifically, to a method for calculating the capacity coordination of a heavy-haul railway collection and distribution system under train group operation. Background Technology

[0002] In existing heavy-haul railway technologies, train group operation, as a new mode of transportation organization, can improve line utilization and transport capacity without large-scale infrastructure expansion. However, existing methods for calculating the capacity coordination of heavy-haul railway collection and distribution systems mainly focus on important node stations in the network, emphasizing the coordination between their connecting lines and the station's own capacity. They fail to consider the unique characteristics of group operation organization, thus failing to accurately reflect the dynamic matching relationship between station and line capacity within each subsystem of collection and distribution under train group operation. Furthermore, they lack a scientific evaluation of the capacity synergy among the three major systems of collection, transport, and distribution, making it difficult to reflect the overall coordination status of the collection and distribution system under train group operation. This results in existing methods for calculating the capacity coordination of collection and distribution systems being ill-suited to the characteristics of group operation organization and failing to accurately reflect the overall synergy of the collection and distribution system.

[0003] Therefore, there is an urgent need for a method to calculate the capacity coordination of heavy-haul railway collection and distribution systems under train group operation, which solves the problem that existing methods for calculating the capacity coordination of collection and distribution systems are difficult to adapt to the organizational characteristics of group operation and cannot accurately reflect the overall collaborative relationship of the collection and distribution system. Summary of the Invention

[0004] The purpose of this invention is to provide a method for calculating the capacity coordination of a heavy-haul railway collection and distribution system under train group operation, thereby improving the aforementioned problems. To achieve the above objective, the technical solution adopted by this invention is as follows:

[0005] Firstly, this application provides a method for calculating the capacity coordination of a heavy-haul railway collection and distribution system under train group operation, including:

[0006] Information on stations and lines within the collection and distribution system is obtained, wherein the stations include loading stations, technical stations, and unloading stations, and the lines include collection lines, transportation lines, and distribution lines;

[0007] Based on the factors influencing the station's capabilities, the operational characteristics of each type of station are classified, analyzed, and their capabilities are constructed to obtain the station's operational capabilities.

[0008] Based on the group dynamics parameters of the collection and distribution system, the capacity of the subsystems of the collection and distribution system is constructed to obtain the line transmission capacity of the subsystems.

[0009] Based on the station's operational capacity and the subsystem's line transport capacity, the system's capacity coordination relationship is calculated to obtain a system capacity coordination degree calculation model.

[0010] Based on the operational theory of the collection and distribution system, the inter-system capacity coordination relationship between the station's operational capacity and the subsystem's line transport capacity is determined, resulting in a calculation model for the inter-system capacity coordination degree.

[0011] Based on the intra-system capacity synergy calculation model and the inter-system capacity synergy calculation model, the capacity synergy of the collection and distribution system is calculated to obtain the coordination degree evaluation result.

[0012] Secondly, this application also provides a device for calculating the capacity coordination of a heavy-haul railway collection and distribution system under train group operation, including:

[0013] The acquisition module is used to acquire information about stations and lines within the collection and distribution system. The stations include loading stations, technical stations, and unloading stations, and the lines include collection lines, transportation lines, and distribution lines.

[0014] The analysis module is used to classify and analyze the operational characteristics of various types of stations and construct their capabilities based on the station's capability influencing factors, thereby obtaining the station's operational capabilities.

[0015] The capacity building module is used to build the capacity of the subsystems of the collection and distribution system based on the group dynamics parameters of the collection and distribution system, and to obtain the line transmission capacity of the subsystem.

[0016] The system module is used to calculate the capacity coordination relationship within the system based on the station's operational capacity and the subsystem's line transport capacity, and to obtain a system capacity coordination degree calculation model.

[0017] The inter-system module is used to calculate the inter-system capacity coordination relationship between the station's operational capacity and the subsystem's line transport capacity based on the operation theory of the collection and distribution system, and to obtain the inter-system capacity coordination degree calculation model.

[0018] The calculation module is used to calculate the capacity bottleneck of the collection and distribution system based on the intra-system capacity coordination calculation model and the inter-system capacity coordination calculation model, and obtain the coordination evaluation result.

[0019] The beneficial effects of this invention are as follows:

[0020] This invention constructs operational capabilities by incorporating the capacity-influencing factors of loading stations, technical stations, and unloading stations to cover the entire collection and distribution process. This breaks through the limitations of traditional single-node assessments, making capacity evaluation more suitable for heavy-haul railways and overcoming the limitations of traditional technologies that only calculate static capacity at a single point. It constructs a system-wide capacity coordination calculation model based on the operational theory of the collection and distribution system, considering the dynamic needs of group trains for multi-station operations, thus solving the problem that traditional methods cannot adapt to the group operation mode of heavy-haul railways. Through the linkage analysis of the two-layer coordination model, capacity bottlenecks are directly calculated to obtain coordination evaluation results. Based on these results, targeted optimizations are performed to avoid blind expansion and modification of the heavy-haul railway collection and distribution system. In summary, this invention solves the problems of existing collection and distribution system capacity coordination calculation methods being unable to adapt to the characteristics of group operation organization and accurately reflect the overall collaborative relationship of the collection and distribution system.

The transport capacity of the collection and transport line is obtained by calculating the number of group trains of the collection and transport line and the preset transport volume fluctuation coefficient.

[0105] In this step, when organizing trains for group operation, the time window and timetable cycle are considered, the number of trains in the group on the transport line is calculated, and then the full load rate of freight trains and the monthly transport volume fluctuation coefficient are introduced to finally obtain the transport capacity of the transport line.

[0106] The formula for calculating the number of trains in the aforementioned freight group is as follows:

[0113] S32: Based on the total operating time and the timetable cycle of the restricted section of the heavy-haul railway in the group dynamics parameters, the throughput capacity is constructed to obtain the throughput capacity of the heavy-haul railway line;

[0114] In this step, the throughput capacity of the heavy-haul railway line includes the throughput capacity of a single-track heavy-haul railway under group operation and the maximum throughput capacity of the entire double-track heavy-haul railway line.

[0115] For single-track heavy-haul railway lines, the throughput capacity is limited by the operating cycle of the busiest section. The throughput capacity of a single-track heavy-haul railway under group operation is:

[0130] In this step, the capacity coordination calculation model of the freight forwarding system assesses the coordination level of the system under current operating conditions by quantifying the capacity matching degree between the transport capacity of the freight forwarding lines and the operational capacity of the freight forwarding system stations. The utilization of the freight forwarding system's capacity depends on the capacity coordination level between the transport capacity of the freight forwarding lines and the operational capacity of the freight forwarding system stations. An imbalance in the capacity of either can trigger a chain reaction: when the loading station's capacity far exceeds the transport capacity of the freight forwarding lines, it will directly lead to the inability to transfer goods at the loading station in a timely manner, which in turn restricts the utilization of the loading station's capacity; when the freight forwarding lines have surplus capacity, it will result in idle resources such as track and signaling equipment, increasing operating costs.

[0131] The expression for the capacity coordination degree calculation model of the collection and transportation system is:

The coordination between the total access capacity and total departure capacity is evaluated based on the transit system's line throughput capacity and station operational capacity. Specifically, the total access capacity is the sum of the smaller values ​​of the access capacities of lines / stations in each direction, and the total departure capacity is the sum of the smaller values ​​of the departure capacities of lines / stations in each direction. For this node station, the closer the total access capacity and total departure capacity are, the less wasted system capacity and the higher the coordination.

[0151] S43: Calculate the capacity coordination relationship within the system based on the station operation capacity of the evacuation system and the evacuation line transport capacity of the subsystem line transport capacity to obtain the evacuation system capacity coordination degree calculation model;

[0152] In this step, the capacity coordination calculation model of the transportation system is used to quantify the matching relationship between the unloading station capacity and the transportation line capacity, and to measure the capacity coordination level of the transportation system.

[0157] S5: Based on the operation theory of the collection and distribution system, the inter-system capacity coordination relationship between the station's operational capacity and the subsystem's line transport capacity is determined to obtain the inter-system capacity coordination degree calculation model.

[0158] like Figure 2 As shown, this step considers the dynamic needs of multi-station operation connections for group trains, solving the problem that traditional methods cannot adapt to the operation mode of heavy-haul railway groups. The coordination degree of the capacity coordination of the collection and distribution system 1, the transportation system 2, and the distribution system 3 is considered. While the internal coordination assessment of the system-wide capacity coordination degree model can solve the capacity imbalance problem of a single system, it cannot cover the capacity bottleneck between the entire system (i.e., coordination degree 4). Therefore, relying solely on the internal capacity coordination degree assessment of the system-wide capacity coordination degree model is insufficient to fully measure the overall coordination level of the collection and distribution system. This step uses an inter-system capacity coordination degree assessment method to achieve quantitative analysis of the inter-system capacity coordination degree, ensuring the efficient operation of the collection and distribution system throughout the entire process under the train group operation mode.

[0185]

[0186] In the formula, For the throughput capacity of the transportation system under group operation; The minimum value; To improve the station throughput capacity under group operation; To improve the throughput capacity of the network under group operation;

[0187] The transportation system capacity is calculated based on its transport capacity, and the expression for the transport system capacity is as follows:

This refers to the average load factor of freight trains. This refers to the load factor of freight trains.

[0190] S53: Based on the operation theory of the collection and distribution system, the system capacity coordination relationship between the unloading station operation capacity and the line transportation capacity of the subsystem is determined to obtain the distribution system capacity.

[0191] In this step, the capacity of the transport system mainly depends on the capacity of the unloading station and the line. For a given unloading station, its transport capacity is... The smaller of the following two values ​​should be taken: one is the station's unloading capacity.

Specifically, the intra-system capacity coordination calculation model yields the capacity coordination assessment results of various stations and line capacities within the system, while the inter-system capacity coordination calculation model yields the capacity coordination assessment results between each subsystem. Based on the above two types of assessment results, an integrated analysis is performed to finally generate the coordination assessment results of the collection and distribution system.

[0204] Existing methods for calculating the capacity coordination of heavy-haul railway collection and distribution systems fail to consider the unique characteristics of group operation organization, thus failing to reflect the capacity matching relationship between stations and lines within each subsystem under train group operation, and also unable to evaluate the overall coordination between collection, transportation, and distribution systems.
