Description

Technical Field

[0001] The present invention relates to the technical field of freight sky-rail transportation, and in particular to a method for determining a freight sky-rail transportation organization plan and a design system. Background Art

[0002] As the scale of the logistics industry continues to expand and logistics transportation equipment continues to improve, the freight skyrail system, as a new type of logistics transportation system, requires a complete engineering design phase from project establishment to implementation to operation, involving multiple disciplines such as transportation, civil engineering, power supply, structure, and signaling. The transportation organization plan is the main design basis for vehicle configuration, loading and unloading process plan, vehicle base scale, and operation management.

[0003] At present, there have been studies on the transportation organization in the fields of rail transit and railway freight. However, for the skyrail system, which is a new freight system, its usage scenarios and transportation characteristics are different from the above-mentioned transportation systems. The transportation organization plans are mostly determined by manual calculation and evaluation, which not only consumes a lot of resources, but also has low design efficiency and has not formed a unified model. Summary of the invention

[0004] The purpose of the present invention is to provide a method and a design system for determining a freight skyrail transport organization plan in view of the defects of the prior art, so as to realize the automatic design of the transport organization plan and improve the design efficiency and design consistency.

[0005] In order to solve the above technical problems, the present invention provides a method for determining a freight sky-rail transportation organization plan, comprising:

[0006] Get basic data;

[0007] Generate a transport organization plan based on the basic data through preset rules and constraints; wherein the preset rules include driving organization plan design rules, vehicle formation plan design rules, loading and unloading plan design rules, vehicle base and wiring plan design rules; the constraints include maximum operating speed, travel speed range, loading and unloading time range, trip interval, stop time, loading and unloading time, station entry and exit time, daily maintenance time, and occasional failure downtime;

[0008] Perform weighted rating on the generated transport organization plans.

[0009] The present invention is based on imported and existing basic data, according to preset rules and constraints, and forms a unified calculation method and multiple calculation values ​​through a solution generation module, automatically generates freight skyrail transportation organization plans, and performs ratings, thereby realizing automatic design of transportation organization plans and significantly improving design efficiency.

[0010] In some embodiments, the basic data includes route data, freight volume data, and operating time data.

[0011] The basic data of the present invention includes route data, freight volume data, and operating time data. According to the route data, freight volume data, and operating time data, the transportation organization plan can be determined by using preset rules and constraints.

[0012] Furthermore, the line data includes line length, number of stations, and design speed; the freight volume data includes annual freight volume target, daily average freight volume, and daily peak freight volume; the operating time data includes annual operating days and daily operating time.

[0013] The line data of the present invention can have multiple groups, each group of line data corresponds to a different line length, number of stations, and design speed. The freight volume data can be used to estimate the annual freight volume target, daily average freight volume, and daily peak freight volume based on historical freight volume. The operating time data can be manually set according to actual conditions.

[0014] In some embodiments, the vehicle formation scheme design rules include selecting vehicles based on the freight volume at each planning stage of the project, combined with the characteristics of freight flow between sites, based on the principle of maximum vehicle utilization, and determining the number of formations based on short- and long-term transportation capabilities.

[0015] The present invention considers the freight volume and freight flow characteristics at each planning stage, takes the maximum vehicle utilization rate as the objective function, selects vehicles, makes the number of vehicles actually used for work or the time to be higher than the total number of vehicles or the total time, and improves the efficiency of resource utilization. Among them, the freight flow characteristics refer to the characteristics of the flow direction of goods. For example, the station includes three stations A, B, and C. During the process of the vehicle going from station A to station C, there is only cargo loading and unloading at station C. During the process of the vehicle going from station C to station A, there is only cargo loading and unloading at station B. The characteristics of the freight flow should be fully considered when the vehicle is grouped.

[0016] Furthermore, the driving organization plan design rules include determining the number of trains that need to be operated at different stages of the project based on the daily / annual operating time, vehicle type, travel speed, station transit time, and imbalance coefficient, in order to achieve the daily / annual target total freight volume and peak freight volume.

[0017] The present invention calculates the number of train pairs required to be operated at different stages of the project based on the daily / annual operating time, vehicle type, travel speed, transit time, and imbalance coefficient, thereby ensuring that the corresponding daily / annual target total freight volume and peak freight volume can be completed at each stage of the project. The imbalance coefficient is an empirical value and can be 1.1 or 1.2.

[0018] Furthermore, the loading and unloading scheme design rules include constructing a matching scheme that adapts to different loading and unloading modes and different loading and unloading equipment of the ART based on vehicle type and freight volume data, with the priority principle of improving loading and unloading efficiency, and forming an operation plan for the loading and unloading equipment.

[0019] The present invention can arbitrarily combine existing different loading and unloading modes and different loading and unloading equipment according to vehicle types and freight volume data, and take the highest loading and unloading efficiency as the objective function, thereby determining the operation plan of the loading and unloading equipment.

[0020] Furthermore, the vehicle base and wiring scheme design rules include positioning requirements based on the number of operating vehicles, the number of spare vehicles, maintenance frequency and maintenance cycle requirements; establishing a vehicle base and wiring scheme based on the principles of vehicle usage status on the main line, timely cleaning of faulty vehicles, and wiring with temporary parking and maintenance functions.

[0021] In some embodiments, the method of weighting and rating the generated transportation organization schemes includes:

[0022] Evaluation indicators are obtained, among which the evaluation indicators of the driving organization plan include the line capacity, full-load transportation capacity, travel speed, and project investment amount; the evaluation indicators of the vehicle formation plan include the type of aerial rail vehicles, the maximum transportation capacity, and the number of bottom vehicles; the evaluation indicators of the loading and unloading plan include the type of loading and unloading equipment, loading and unloading efficiency, and the ratio of loading and unloading equipment to aerial rail vehicles; the evaluation indicators of the vehicle base and wiring plan include the utilization rate and reuse rate of each line in the vehicle base, and the investment proportion; the coverage of temporary stop lines, the coverage of maintenance lines, and the mileage length proportion.

[0023] The present invention extracts evaluation indicators from the driving organization plan, the vehicle formation plan, the loading and unloading plan, the vehicle base and the wiring plan respectively, so as to rate the entire transportation organization plan.

[0024] Furthermore, the method for weighted rating of the generated transport organization plan includes: setting a first weight value for the vehicle grouping plan evaluation index, setting a second weight value for the vehicle grouping plan evaluation index, setting a third weight value for the loading and unloading plan evaluation index, and setting a fourth weight value for the vehicle base and wiring plan evaluation index. The sum of the first weight value, the second weight value, the third weight value, and the fourth weight value is 1, and the transport organization plan is weightedly rated.

[0025] The present invention can set different weight values ​​according to the importance of the driving organization plan, vehicle formation plan, loading and unloading plan, vehicle base and wiring plan, so as to rank the entire transportation organization plan.

[0026] In a second aspect, the present invention provides a freight sky-rail transport organization scheme design system, including a basic data module, a scheme generation module and a human-computer interaction module;

[0027] The basic data module is used to import and store route data, freight volume data, and operating time data;

[0028] The scheme generation module is used to generate a transport organization scheme based on the basic data through preset rules and constraints, obtain evaluation indicators and perform weighted rating on the generated transport organization scheme;

[0029] The human-computer interaction module is used for operators to interact with the system. They can select route data, freight volume data, and preset rules, boundary conditions, and constraints, and store and display the generated driving organization plans and evaluation indicators.

[0030] The present invention establishes a freight sky-rail transport organization design system, based on imported and existing basic data, preset rules and constraints, and forms a unified calculation method and multiple calculation values ​​through a solution generation module, so as to productize the freight sky-rail transport organization design system. The freight sky-rail transport organization design system can be a calculation program, a software product, or an electronic device that stores program codes through a U disk, a mobile hard disk, a CD, a cloud disk, etc.

[0062] The following is an actual case to illustrate:

[0063] S1. Obtain basic data.

[0064] Among them, the line data: the line length is 4km, the number of stations is 4, namely A1, B1, B2, A2, and the design speed is 50km / h;

[0065] Freight volume data: 9 million tons per year; 30 tons per box; 1,000 boxes per day;

[0066] Operating time data: 20 hours of operating time per day, 300 operating days per year.

[0067] S2. Generate a transportation organization plan based on the basic data through preset rules and constraints:

[0068] Design of train operation organization plan: Based on the daily / annual operation time, vehicle type, travel speed, transit time (i.e. loading and unloading time), daily maintenance time, and imbalance coefficient, determine the number of train pairs required to be operated at different stages of the project in order to achieve the daily / annual target total freight volume and peak freight volume;

[0069] The full-day operation time is 20 hours, and the annual operation days are 300 days; the vehicle is a cargo loading and unloading vehicle with or without changing boxes; the travel speed range is 0-50km / h; the loading and unloading time range is 90s-180s; the daily maintenance time is 4 hours;

[0070] It is determined that the number of vehicles operating at full load is 15, which can meet the annual requirement of 9 million tons.

[0071] Vehicle marshaling scheme design: According to the freight volume at each planning stage of the project, combined with the characteristics of freight flow between stations, based on the principle of maximum vehicle utilization, vehicle selection is carried out, and the number of marshaling is determined according to the short-term and long-term transportation capacity. Among them, the full-line operation plan: A1 departure-B1 arrival-B1 unloading-B1 empty car dispatch-B2 arrival-B2 loading-B2 loading dispatch-A2 arrival-A2 unloading-A2 empty car dispatch-A1 arrival-A1 loading, the characteristics of freight flow between stations are loading at A1 station, unloading at B1 station, loading at B2 station, unloading at A2 station, and empty vehicles return from A2 station to A1 station for loading. Based on the principle of maximum vehicle utilization, the vehicle marshaling scheme is determined to adopt single-car, 2-car and 6-car marshaling.

[0072] Design of loading and unloading plan: Use vehicles that load and unload goods by changing containers or without changing containers.

[0073] S3. Evaluation of transportation organization plan:

[0074] According to the scheme in S2, multiple transport organization schemes can be generated. Here is one of the transport organization schemes: travel speed: 15-45km / h; vehicle marshaling scheme: 5-car marshaling; vehicle type: box-changing and loading and unloading type; 15 vehicles at full load; full load transport capacity: 1,170 boxes / day; the ratio of the number of loading and unloading equipment to the number of aerial rail vehicles: 1:1-1:6, 1:2-1:6. The above transport organization scheme meets the annual requirement of 9 million tons.

[0075] By comparing various transport organization plans, the one with the best economic efficiency can be selected as the optimal transport organization plan.
