However, in the existing railway transportation system, the problem of train scheduling is becoming increasingly prominent. Due to the diverse transportation needs and limited transportation resources, how to reasonably and efficiently schedule trains to ensure that goods are delivered to the destination in a timely and accurate manner has become a major challenge facing the railway transportation industry.

[0003] At present, the railway transportation industry generally adopts experience-based scheduling methods. These methods formulate train scheduling plans by analyzing information such as transportation direction, monthly cumulative transportation quantity, transportation train type, and cargo type, combined with the experience of dispatchers. At the same time, by optimizing the number of train stops and loading and unloading speeds at railway stations, transportation efficiency can be improved. To a certain extent, these methods can alleviate the pressure of train scheduling and ensure the orderly progress of railway transportation.

[0004] However, existing railway transport scheduling methods have the following problems: (1) The scheduling methods are too dependent on manual experience and are easily affected by subjective factors, resulting in inaccurate scheduling results; (2) The methods or calculations for deciding how to allocate transport resources to different transport units are not precise or detailed enough; (3) The scheduling schemes lack flexibility and are difficult to respond to emergencies and dynamic changes in transport demand.

In the description of the embodiments of the present application, the meaning of "multiple" is more than two, unless otherwise clearly and specifically defined.

[0025] Embodiment 1 Please refer to Figure 1 , Figure 1 1 is a flow chart of a railway transport train scheduling method provided by an embodiment of the present invention, the method comprising the following steps: S100, obtaining the transport directions, monthly cumulative transport quantities, transport train categories, cargo categories, transport train quantities, each transport route station and the unloading quantity at each transport route station of multiple transport units, and the train stop quantity and loading and unloading speed at multiple railway stations; The transport direction of a transport unit refers to the basic path selected by the transport unit when transporting goods, which can be forward or reverse.

[0026] The monthly cumulative transport quantity of a transport unit refers to the total amount of cargo transportation completed by the transport unit within a natural month.

[0027] The transport train category of a transport unit refers to the type of train used by the transport unit, which is classified according to different standards such as the function, speed, load capacity, etc. For example: covered wagon, intermodal transport, tank wagon, flat wagon and open wagon, etc.

[0028] The cargo category of a transport unit refers to the type of cargo carried by the transport unit, which is usually classified according to the nature, form and purpose of the cargo, for example: internal chemicals of the shipping unit, external chemicals of the shipping unit and general cargo, etc.

[0029] The number of transport trains of a transport unit refers to the number of trains put into use by the transport unit within a certain statistical period, which is used to measure the transport capacity or the size of the transport task.

[0030] The transport route stations of a transport unit refer to all the stations that the transport unit train needs to stop or pass through during the cargo transportation process, including the departure station, the terminal station and various stopover stations in between.

[0031] The unloading quantity at the transport unit's transport route stations refers to the total amount of goods unloaded from the train at each station along the transport route. Usually, the unloading quantity at each station will be different.

[0032] The number of train stops at a railway station refers to the total number of trains that stop at a railway station during the statistical period. This number can reflect the busyness and scheduling efficiency of the station.

[0033] The loading and unloading speed of a railway station refers to the efficiency of cargo loading and unloading operations at the railway station, usually measured by the amount of cargo loaded and unloaded per unit time, such as the number of tons loaded and unloaded per hour.

[0034] S200, determining the dispatch value of each transport unit based on the transport direction, monthly cumulative transport quantity, transport train type and cargo type of each transport unit; It should be noted that the advantages of selecting the transport direction, monthly cumulative transport quantity, transport train category and cargo category of the transport unit to calculate the dispatch value of the transport unit are described below: 1. Transport direction (forward and reverse) (1) Improving the utilization rate of transportation equipment: Transportation units can make full use of transportation tools by taking into account both forward and reverse transportation, avoiding vehicles returning empty-handed. For example, railway freight trains can take on reverse transportation tasks after completing forward transportation, which can improve utilization and reduce unit transportation costs.

[0035] (2) Optimizing the flow of the transport network: From the perspective of the overall transport network, the rational arrangement of two-way transport can balance the transport flows of different routes, avoid uneven pressure and idleness of routes caused by one-way transport, and improve the efficiency of the entire network.

[0036] (3) Enhancing the flexibility and adaptability of transport units: Considering the transport direction in both directions enables transport units to better respond to market changes and maintain operations by taking on reverse transport business when the demand for forward transport decreases.

[0037] 2. Monthly cumulative transportation quantity (1) Evaluating transportation capacity and efficiency: It is a key indicator to measure the transportation capacity of transportation units. It can be used to understand the work results, provide scheduling incentives based on the transportation volume, analyze transportation efficiency, identify bottlenecks and optimize scheduling plans.

[0038] (2) Planning long-term transportation tasks: Future transportation demand can be predicted based on its changing trend. If the transportation volume increases, the scheduling tasks can be increased accordingly. If it decreases, the transportation route or service object needs to be adjusted.

[0039] III. Transport train types (covered cars, intermodal transport, tank cars, flat cars and open cars) (1) Ensuring cargo safety and quality: Different train types are suitable for different cargoes and can provide corresponding protection. For example, covered cars protect ordinary cargoes that are afraid of rain and sun, and tank cars ensure the safety of liquid and gas cargo transportation.

[0040] (2) Improving transportation efficiency: Selecting the appropriate train type according to the characteristics of the cargo can improve loading and unloading efficiency. Flat cars and open cars are convenient for loading and unloading large and irregular cargo. Intermodal trains can combine the advantages of multiple transportation modes to shorten the entire transportation time.

[0041] (3) Optimizing transportation costs: Choosing train types based on cargo can reduce costs. For ordinary cargo with low requirements, open wagons are cheaper. For high-value and fragile cargo, well-protected trains are more expensive but may offer better overall economic benefits. Multimodal trains can reduce overall transportation costs.

[0042] IV. Cargo categories (chemical products from within the shipping unit, chemicals from outside the shipping unit, and general cargo) (1) Accurately matching transportation resources: Different types of goods require different transportation conditions and safety measures. Selecting appropriate trains and allocating related resources based on the characteristics of the goods can improve transportation accuracy.

[0043] (2) Effectively manage transportation risks: Chemical products are dangerous. Differentiating between internal and external chemicals can better manage risks. Internal chemical transport units have a better understanding and can accurately control risks. External chemical products require strict review of relevant information. Ordinary goods also require appropriate risk assessment and management.

[0044] (3) Meeting the needs of different customers: Considering the cargo category helps to meet the high quality requirements of chemical enterprise customers for chemical product transportation and the diverse needs of general cargo customers for efficient and low-cost transportation.

[0045] In summary, comprehensive consideration of the four aspects of the transport unit's transport direction, monthly cumulative transport quantity, transport train category, and cargo category will help the transport unit optimize the transport workflow, improve transport efficiency, reduce risks, better meet market and customer needs, and promote high-quality and sustainable development of the transport business. Therefore, the embodiment of the present invention selects the transport unit's transport direction, monthly cumulative transport quantity, transport train category, and cargo category to calculate the dispatch value of the transport unit.

[0046] In one embodiment, step S200 specifically includes: S210, matching the transport direction of the transport unit with a preset transport direction score table to obtain a direction score of the transport unit; wherein the preset transport direction score table is used to represent a mapping relationship between the transport direction of the transport unit and the direction score of the transport unit; The following is an exemplary introduction to the preset transport direction score table, as shown in Table 1 below: Table 1 Preset transport direction score table

[0047] For ease of understanding, the following is an example with reference to Table 1: Assuming that the transport direction of the transport unit is forward, it can be seen from Table 1 above that the direction score of the transport unit is 90 points.

[0048] S220, matching the transport train category of each transport unit with a preset transport train category score table to obtain the vehicle score of each transport unit; wherein the preset transport train category score table is used to represent the mapping relationship between the transport train category of each transport unit and the vehicle score of each transport unit; The following is an exemplary introduction to the preset transport train category score table, as shown in Table 2 below: Table 2 Preset transport train category scores

[0049] For ease of understanding, the following is an example with reference to Table 2: Assuming that the transport unit's transport train type is a boxcar, then from the above Table 2 we can see that the transport unit's vehicle score is 70 points.

[0050] S230, matching the cargo category of each transport unit with a preset cargo category score table to obtain the cargo score of each transport unit; wherein the preset cargo category score table is used to represent the mapping relationship between the cargo category of each transport unit and the cargo score of each transport unit; The following is an illustrative introduction to the preset cargo category scoring table, as shown in Table 3 below: Table 3 Preset cargo category scoring table

[0051] For ease of understanding, the following is an example with reference to Table 3: Assuming that the cargo category of the transport unit is ordinary cargo, then from the above Table 3 we can see that the cargo score of the transport unit is 85 points.

[0052] S240, calculating the ratio of the monthly cumulative transport quantity of each transport unit to the preset monthly planned transport quantity corresponding to each transport unit, to serve as the planned score of each transport unit; Specifically, assuming that the monthly cumulative transportation quantity of the transport unit is 50 tons, and the preset monthly planned transportation quantity is 100 tons, then the planned score of the transport unit = 50 / 100 = 0.5.

[0053] S250, obtaining a dispatch value of each transport unit based on the direction score, vehicle score, cargo score and plan score of each transport unit.

[0054] Specifically, step S250 includes: Use the following formula to calculate the direction score, vehicle score, cargo score and plan score of the transport unit to obtain the dispatch value of the transport unit; ;in, represents the dispatch value of the transport unit, The weight value representing the direction score of the transport unit. Indicates the direction score of the transport unit. The weight value representing the vehicle score of the transport unit, represents the vehicle score of the transport unit, The weight value representing the cargo score of the transport unit, Indicates the cargo value of the transport unit, The weight value representing the planned score of the transport unit, Indicates the planned score of the transport unit.

[0055] It is understandable that the weight of the direction score of the transport unit reflects the importance of the transport unit in the accuracy of the driving direction. If the weight of the direction score of the transport unit is large, it means that when evaluating the comprehensive dispatch value of the transport unit, the accuracy of the transport direction is highly valued.

[0056] It is understandable that the weight of the transport unit's vehicle score reflects the importance of the condition of the transport vehicle itself in the overall assessment. If the weight of the transport unit's vehicle score is large, it means that the transport unit pays more attention to the performance and maintenance of the vehicle.

[0057] It is understandable that the weight of the cargo score of the transport unit reflects the importance of the cargo status in the comprehensive assessment. When the weight of the cargo score of the transport unit is large, it means that there is great concern about the integrity, loading and unloading conditions, etc. of the cargo.

[0058] It is understandable that the weight of the transport unit's plan score reflects the importance of the transport plan execution in the overall evaluation. If the weight of the transport unit's plan score is large, it means that the transport unit attaches great importance to carrying out transport operations according to the predetermined plan.

[0059] Therefore, setting different weights of the direction score of the transport unit, the vehicle score of the transport unit, the cargo score of the transport unit, and the plan score of the transport unit can indicate the importance of the transport unit to different aspects. For example, if the weight of the plan score of the transport unit is set to a larger value, it indicates the completion of the transport plan of the more important transport unit.

[0060] In the embodiment of the present invention, the weight value of the direction score of the transport unit, the weight value of the vehicle score of the transport unit, the weight value of the cargo score of the transport unit and the weight value of the plan score of the transport unit are not specifically limited and can be reasonably set according to the actual needs of the transport unit.

[0061] In one embodiment, methods for determining the weight value of the direction score of the transport unit, the weight value of the vehicle score of the transport unit, the weight value of the cargo score of the transport unit, and the weight value representing the planned score of the transport unit include but are not limited to: empirical judgment method, statistical analysis method, hierarchical analysis method and fuzzy comprehensive evaluation method.

[0062] The following is an example of analytic hierarchy process: Construct a hierarchical model: Take the comprehensive evaluation of the transport unit as the target layer, and the direction score, vehicle score, cargo score and plan score as the criterion layer. If necessary, you can also subdivide the indicator layer under the criterion layer. For example, under the vehicle score, you can subdivide indicators such as vehicle safety performance and vehicle maintenance cost.

[0063] Constructing a judgment matrix: It is constructed by comparing the relative importance of each criterion. For example, for the comparison of the direction score and the vehicle score, a 1-9 scale is used. 1 means that the two factors are equally important, and 9 means that one factor is absolutely more important than the other. Assuming that the expert believes that the direction score is slightly more important than the vehicle score, the value of the corresponding position in the judgment matrix can be 3.

[0064] Hierarchical single sorting and consistency test: Calculate the maximum eigenvalue of the judgment matrix and its corresponding eigenvector, and normalize the eigenvector to obtain the weight vector of each factor. At the same time, a consistency test is performed to ensure the logical consistency of the expert scoring. If the consistency ratio is less than 0.1, the consistency of the judgment matrix is ​​considered acceptable.

[0065] Applicable scenarios: Applicable to complex transport unit evaluation systems, which can comprehensively consider the relationship between multiple factors, especially when factors at different levels need to be considered.

[0066] For ease of understanding, the following example is given: Assume that the direction score of the transport unit is 90, the vehicle score of the transport unit is 70, the cargo score of the transport unit is 85, and the plan score of the transport unit is 0.5.

[0067] The weight value of the direction score of the transport unit is 0.2, the weight value of the vehicle score of the transport unit is 0.1, the weight value of the cargo score of the transport unit is 0.2, and the weight value of the plan score of the transport unit is 0.5.

[0068] Calculated by the above formula: 90*0.2+70*0.1+85*0.2+0.5*0.5=42.25, that is, the dispatch value of the transport unit is 42.25.

[0069] S300, sorting the dispatch values ​​of each transport unit from large to small to obtain the dispatch order of each transport unit; For ease of understanding, the following example is given: Assume that there are 10 transport units: A, B, C, D, E, F, G, S, R, and G. Among them, the dispatch value of A transport unit is 25.5, the dispatch value of B transport unit is 42.25, the dispatch value of C transport unit is 12.8, the dispatch value of D transport unit is 10.2, the dispatch value of E transport unit is 65.3, the dispatch value of J transport unit is 33.7, the dispatch value of G transport unit is 78.9, the dispatch value of S, the dispatch value of R, the dispatch value of G transport unit is 5.6, the dispatch value of R, and the dispatch value of G transport unit is 95.1.

[0070] Then they are sorted from large to small according to the scheduling value, that is, the scheduling order of the transport units is: Gui transport unit (95.1), Ren transport unit (82.4), Geng transport unit (78.9), Wu transport unit (65.3), Yi transport unit (42.25), Ji transport unit (33.7), Jia transport unit (25.5), Bing transport unit (12.8), Ding transport unit (10.2) and Xin transport unit (5.6).

[0071] S400, in accordance with the dispatching order of each transport unit, based on the number of train stops and loading and unloading speeds at multiple railway stations, as well as the number of transport trains of each transport unit, each transport route station and the unloading quantity at each transport route station, generate the transport dispatching instructions for each transport unit.

[0072] In one embodiment, step S400 specifically includes: S1, determining the stations among multiple railway stations that are consistent with the stations on each transport route of the current transport unit as preliminary scheduling stations, and obtaining multiple preliminary scheduling stations; S2, calculating the ratio of the number of the plurality of preliminary scheduling sites to the number of the plurality of sites of the railway; S3, when the ratio is greater than the preset ratio, the difference between the preset total number of train stops corresponding to each preliminary scheduling station and the number of train stops at each preliminary scheduling station is calculated to obtain the remaining number of trains accommodated at each preliminary scheduling station; S4, when the number of remaining trains at each preliminary scheduling station is greater than the number of transport trains of the transport unit, the ratio of the unloading quantity to the loading and unloading speed at each preliminary scheduling station is calculated to obtain the loading and unloading time of each preliminary scheduling station; S5, when the number of preliminary scheduling sites where the loading and unloading time is less than the preset time is greater than the preset number, the sum of the number of train stops at each preliminary scheduling site and the number of transport trains is calculated to obtain the current number of train stops at each preliminary scheduling site, and the current transport unit is marked as an approved transport unit; S6, update the number of train stops at each preliminary scheduling site to the current number of train stops at each preliminary scheduling site, update the current transport unit to the next transport unit according to the scheduling order of each transport unit, and return to step S1, until the number of train stops at any station of the railway is greater than the corresponding preset total number of train stops, generate the transportation scheduling instructions for each approved transport unit.

[0073] For ease of understanding, the following example is given: Suppose there are 10 transport units: Jia (25.5), Yi (42.25), Bing (12.8), Ding (10.2), Wu (65.3), Ji (33.7), Geng (78.9), Xin (5.6), Ren (82.4) and Gui (95.1).

[0121] A23 station: Number of train stops: 16, total number of preset train stops: 20, unloading speed: 130 tons per hour.

[0122] Step 1 (determine the preliminary dispatch site) Take the first transport unit Gui as an example. The stations it passes through are A1, A2, A3, A4, A5, A6, A7, A8, A9, and A10. Compare them with the railway-related stations (A1 station, A2 station, A4 station, A5 station, A7 station, A8 station, A10 station, A11 station, A12 station, A14 station, A15 station, A16 station, A19 station, A20 station, A22 station, and A23 station) to find the overlapping stations. These overlapping stations are the preliminary scheduling stations. For the Gui transport unit, the preliminary scheduling stations are A1, A2, A4, A5, A7, A8, and A10 stations. In the same way, the preliminary scheduling stations corresponding to other transport units can be determined in turn.

[0123] Step 2 (Calculate the ratio) Calculate the ratio of the number of preliminary dispatching stations to the number of railway-related stations. For example, for the Gui transport unit, there are 7 preliminary dispatching stations (A1, A2, A4, A5, A7, A8, A10) and 16 railway-related stations, so the ratio is 7 ÷ 16. The other transport units also calculate their corresponding ratios in the same way.

[0124] Step 3 (When the ratio is greater than the preset ratio, calculate the remaining number of trains to accommodate) Assume that the preset ratio is set to a specific value (not clearly given in the question, only used as an example to illustrate the logic), when the ratio calculated by a transport unit is greater than the preset ratio, for example, taking a preliminary dispatching station A corresponding to a transport unit as an example, first clarify the preset number of train stops at station A (such as the total number of preset train stops at station A1 is 20), and the current number of train stops at station A (such as the number of train stops at station A1 is 15), and subtract the current number of train stops from the preset number of train stops to get the remaining number of trains that can be accommodated at the preliminary dispatching station. This method is used to calculate each preliminary dispatching station corresponding to the transport unit to obtain the remaining number of trains that can be accommodated at each preliminary dispatching station.

[0125] Step 4 (calculate loading and unloading time when the remaining number of trains is met) When the number of trains remaining to be accommodated at each preliminary dispatching station is greater than the number of trains transported by the transport unit (for example, if a transport unit has 10 trains, the number of trains remaining to be accommodated at each preliminary dispatching station is greater than 10), take a preliminary dispatching station as an example, such as station A1, and the unloading quantity of the station is known (such as the transport unit Gui unloads 80 tons at station A1) and the unloading speed (the unloading speed of station A1 is 120 tons per hour), the loading and unloading time of the preliminary dispatching station is obtained by dividing the unloading quantity by the loading and unloading speed (80÷120≈0.66 hours). This operation is performed for each preliminary dispatching station corresponding to the transport unit to calculate the loading and unloading time of each preliminary dispatching station.

[0126] Step 5 (calculate the number of stops for the current train when the loading and unloading time conditions are met) When the number of preliminary scheduling stations with loading and unloading time shorter than the preset time (the specific value of the preset time is not specified in the question, only the logic is shown), for each preliminary scheduling station, add the current number of train stops (such as 15 trains at station A1) and the number of transport trains of the transport unit (such as 10 trains for a transport unit) (15+10), and the current number of train stops at the preliminary scheduling station is obtained. This calculation is performed for each preliminary scheduling station that meets the conditions.

[0127] Step 6 (Update and loop operation) Update the number of train stops at each preliminary dispatching station to the current number of train stops just calculated, and then update the current transport unit to the next transport unit according to the dispatching order of the given transport unit (Gui transport unit, Ren transport unit, Geng transport unit...Xin transport unit), and then return to the first step to start a new round of operations. This process is repeated until the number of train stops at any railway station is greater than the corresponding preset number of train stops, and the transport dispatch instructions for each approved transport unit are generated.

[0128] In summary, steps one to six are to reasonably arrange the dispatch of transport units at railway stations through continuous comparison, calculation, judgment and update operations, to ensure that the accommodation and transportation links of railway stations can be carried out in an orderly and efficient manner, and to avoid the number of trains stopping at the station exceeding the preset capacity.

[0129] S500, the transport dispatching instructions of each transport unit are issued to each transport unit, so that each transport unit can transport according to the corresponding transport direction, transport train type, cargo type, number of transport trains, each transport route station and the unloading quantity of each transport route station.

[0131] Beneficial effects of the present invention: (1) By introducing a method to determine scheduling values ​​based on factors such as transport direction, monthly cumulative transport quantity, transport train type, and cargo type, the reliance on manual experience in the scheduling process is reduced, making the scheduling results more objective and accurate.

[0132] (2) By taking into account in detail the number of train stops and loading and unloading speeds at railway stations, this method provides a more accurate resource allocation calculation, ensuring that transportation resources can be reasonably allocated according to actual demand.
