Technical Field
[0001] The present invention relates to the field of logistics transportation control, and in particular to a transportation coordination and dispatching control method for a multimodal transport system. Background Art
[0002] Intermodal transport refers to the transportation process completed by two or more means of transportation connecting and transferring with each other, which is collectively referred to as composite transport. Intermodal transport service systems generally have multiple transportation systems, including water transport, land transport, air transport, rail transport and other modes of transportation. Intermodal transport includes two categories: international and domestic, which are classified according to whether they are cross-border. When operating, intermodal operators generally need to plan and design transportation to achieve transportation scheduling control based on the intermodal transport system, such as a method for calculating an intermodal transport scheme with a patent application number of 201910856865.0, which discloses a method for obtaining a transportation scheme that meets customer demand information, and providing multiple transportation schemes that meet the needs to customers through an output interface for their selection, and then, through a reservation interface, according to the transportation scheme selected by the user, multiple logistics platforms are combined to reserve the transportation for the corresponding time period. This scheme can determine the transportation scheme for logistics transportation, thereby realizing the transportation of logistics.
[0003] However, the above patent solves the calculation of transportation plans in the early stage of transportation. However, in the process of logistics transportation, transportation demand can be generated in real time, and the arranged transportation vehicles are not all fully loaded. For the transportation tasks with newly generated demand, how to realize the allocation and scheduling of transportation capacity to achieve multimodal transport scheduling control is a technical problem that needs to be solved. The above patent cannot solve this technical problem. Summary of the invention
[0004] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a transportation coordination and scheduling control method for a multimodal transport system, which performs scheduling control on newly generated transportation demands through analysis and calculation to meet the logistics transportation through scheduling transportation capacity of the multimodal transport system, thereby achieving the purpose of final scheduling transportation.
[0005] In order to achieve the above object, the technical solution adopted by the present invention is: a transport coordination and dispatching control method of a multimodal transport system, comprising the following steps:
[0006] (1) Obtain new logistics and transportation demands in real time and obtain new logistics demand information;
[0007] (2) According to the cargo origin and destination and cargo volume in the newly added logistics demand information, select the in-transit transportation vehicles that meet the transportation requirements, score each in-transit transportation vehicle when transporting the newly added logistics, obtain the score of each in-transit transportation vehicle when transporting the newly added logistics, recommend the in-transit transportation vehicle to transport the newly added logistics demand according to the score, and complete the scheduling control.
[0008] The control method also includes: obtaining the transportation information of each individual in transit, the transportation information including the real-time carrying capacity, full load and transportation route of the individual means of transport in transit, and then comparing the newly added transportation demand information with the transportation information of the individual means of transport in transit, and screening out a number of individuals of the means of transport in transit that meet the requirements and can meet the newly added transportation demand information as the individuals of the means of transport to be determined.
[0009] The method also includes, when obtaining the individual transport means to be determined, first, performing a first round of screening according to the transport volume / freight volume in the transport demand information, comparing the remaining cargo volume of each individual transport means in transit with the freight volume in the demand information, and taking the individual transport means in transit whose remaining cargo volume is greater than the freight volume in the demand transport information as the result of the first round of screening, and then performing a second round of screening on each individual transport means in the first round of screening results, screening the overlap of transport routes, and selecting the individual transport means in transit whose transport routes pass through the location of the newly added transport demand or the individual transport means whose location of the newly added transport demand belongs to a stop on the transport route as the individual transport means in transit of the second round of screening results according to the transport routes of the individual transport means in transit; and then entering a third round of screening, and screening and analyzing each individual transport means in transit according to the second round of screening results, and screening the individual transport means in transit that pass through the destination corresponding to the newly added demand information according to the transport paths and transport routes in the individual transport means in transit, and all the individual transport means in transit in the results obtained after the third round of screening are the individual transport means to be determined.
[0010] When obtaining the individual pending means of transport, the remaining cargo capacity refers to the full load of the individual means of transport in transit minus the real-time transport capacity. The transportation route of the individual means of transport in transit refers to the route map from the origin to the destination during the transportation process of the goods in transit, which is planned by the navigation system.
[0011] When obtaining pending transport individuals, if the number of transport individuals in the result of the first round of screening is 0, then all the transport individuals in transit are taken as the results and subjected to the second and third rounds of screening in turn to obtain the transport individuals in transit as the split transport individuals, and each split transport individual is scored for transporting the newly added goods, to obtain the score of each split transport individual, and the top n split transport individuals with the highest scores are selected as the transportation methods for the newly added goods demand and recommended to the service provider for scheduling control, where the value of n is determined according to the amount of goods in the newly added logistics demand and the remaining cargo capacity of the transport individuals.
[0012] The control method also includes taking individual pending transport vehicles or splitting individual transport vehicles, giving a score to the way of using each individual pending transport vehicle to transport the new transport demand, making a recommendation based on the size of the score, sorting the scores from large to small, using one of the individual transport vehicles with the largest score or the top score to perform transport scheduling control for the new demand, and issuing scheduling control instructions to the individual transport vehicles.
[0013] The method also includes, during scheduling control, if the number of pending transport individuals is 0 or the number of split transport individuals is less than 2 or the total remaining cargo capacity of all split transport individuals is lower than the cargo capacity of the newly added logistics cargo demand, then it is determined that the newly added logistics demand cannot be completed by the transport individuals in transit, and a corresponding reminder message is output.
[0014] When scoring the additional logistics demand for each individual transport tool, obtain the location information of each individual transport tool, and use the location information to calculate the distance information generated by each individual transport tool in transporting the additional logistics goods demand to the destination. Based on the distance information, the corresponding time cost can be calculated; obtain the order amount in the additional logistics demand information, and calculate the additional profit information; and score the transportation using each individual transport tool based on the time cost and profit information.
[0015] The method for obtaining scores based on time cost and new profit includes: pre-building a comparison table of time cost, new profit and expert scores; then using a neural network to learn the comparison table information, that is, time cost and new profit are used as inputs of the neural network model, and expert scores are used as outputs of the neural network, which are input into the neural network model for training, and the threshold weights in the neural network are updated through training. The trained neural network model is used to output scores corresponding to the input time cost and new profit.
[0016] After the individual transport vehicle issues a dispatch control instruction, the dispatch execution status of the individual transport vehicle is monitored in real time, and early warning information is issued based on the real-time monitoring status.
[0017] The advantages of the present invention are: through analysis and calculation, the newly generated transportation demand is dispatched and controlled to meet the logistics transportation through the multimodal transport system to dispatch the transportation capacity and thus achieve the purpose of final dispatch transportation; priority is given to the use of in-transit transportation tools to transport the new demand, thereby increasing the full load rate of each transportation and reducing cost expenditure; the new demand for individual transportation of each in-transit transportation tool is scored based on time cost and new profit, and the transportation scheduling requirements for time cost and profit are met to the maximum extent. Based on this, the dispatch transportation mode is scored, and scientific, reliable and cost- and profit-optimized dispatch control can be achieved; the execution of dispatch control is monitored and recorded, timely feedback is given, and when dispatch control is unacceptable, new dispatch control is arranged to meet the requirements of logistics control and dispatch control.

[0018] The following is a brief description of the contents expressed in the drawings of the present invention and the symbols in the drawings:
[0019] Figure 1 A schematic diagram of a data transmission architecture of a scheduling control method of the present invention;
[0020] Figure 2 This is a schematic diagram of the scoring output principle of the present invention. DETAILED DESCRIPTION
[0021] The specific implementation of the present invention will be further explained in detail below by describing the optimal embodiment with reference to the accompanying drawings.
[0022] A multimodal transport dispatching control method comprises the following steps:
[0023] Obtain new logistics and transportation demands in real time and obtain new logistics demand information;
[0024] According to the cargo origin and destination and cargo quantity in the newly added logistics demand information, select the in-transit transport vehicles that meet the transportation requirements, score each in-transit transport vehicle for transporting the newly added logistics, obtain the score of each in-transit transport vehicle when transporting the newly added logistics, and recommend the in-transit transport vehicles for new logistics demand according to the score.
[0025] The new logistics demand information is entered by the cargo transporter or cargo demander into the server platform through a mobile terminal device. The server platform obtains the new logistics demand and its logistics information, and then processes the logistics demand information and outputs the corresponding recommendation information to the service provider, so that the service provider can dispatch the transportation tool. A data collection terminal is set on each individual transportation tool. The data collection terminal can be a special input device that can input the order data, transportation data and other related data of the individual transportation tool; the individual transportation tool refers to a specific transportation tool, which can be a ship, a vehicle or an airplane, etc. Therefore, the data of each individual transportation tool can be analyzed, and the data can be uploaded to the server platform for processing through the 5G network, and then the scheduling results can be analyzed and the corresponding scheduling instructions can be output to complete the rapid transportation of new transportation needs under various intermodal modes.
[0026] The newly added logistics demand information includes the type of goods, the quantity of goods, the origin and destination of goods. Since the service provider has multiple modes of transportation such as sea transportation, air transportation, vehicle transportation and rail train transportation, there are multiple transport individuals with multiple modes of transportation in the transportation process to transport goods to the destination. Therefore, the in-transit transport tool individuals are preferred to transport the newly added demand, so as to achieve full-load transportation, improve the transportation utilization rate and save cost expenditure. In-transit transport tool individuals refer to transport tool individuals such as vehicles, trains, ships, and airplanes that are in transit. Each transport individual will have a transportation number, and one transport individual corresponds to a transportation number; such as vehicle transportation numbers C01, C02...; obtain the transportation information of each in-transit transport individual, which includes the real-time carrying capacity, full load and transportation route of the in-transit transport tool individual, and then compare the newly added transportation demand information with the transportation information of the in-transit transport tool individual, and select a number of in-transit transport tool individuals that meet the requirements and can meet the newly added transportation demand information. These individuals are called pending transport tool individuals.
[0027] When obtaining individual pending transport vehicles, first, a first round of screening is performed based on the transport volume / freight volume in the transport demand information, and the remaining cargo capacity of each individual transport vehicle in transit is compared with the freight volume in the demand information. The individual transport vehicle in transit whose remaining cargo capacity is greater than the freight volume in the demand transport information is taken as the result of the first round of screening. Then, a second round of screening is performed on each individual transport vehicle in the first round of screening results to screen the overlap of transport routes. According to the transport routes of the individual transport vehicles in transit, the individual transport vehicles in transit whose transport routes pass through the location of the new transport demand are selected as the individual transport vehicles in transit in the second round of screening results. Then, a third round of screening is performed. According to the results of the second round of screening, each individual transport vehicle in transit is screened and analyzed, and the individual transport vehicles in transit that pass through the destination corresponding to the new demand information are screened based on the transport paths and routes in the individual transport vehicles in transit. All the individual transport vehicles in transit in the results obtained after the third round of screening are pending transport vehicle individuals.
[0028] When obtaining the individual transport vehicles to be determined, the remaining cargo capacity refers to the full load of the individual transport vehicles in transit minus the real-time transport capacity. The transportation data of each individual transport vehicle is recorded through a mobile app or a dedicated input terminal to meet the needs of scheduling and processing. The transportation route of the individual transport vehicle in transit refers to the route map from the origin to the destination during the transportation of the goods in transit. It is planned by the navigation system. When the origin of the new logistics transportation demand is located at the place where the route passes, the origin of the new logistics transportation demand is on the transportation route, which meets the needs of the second round of screening; similarly, when the destination of the new logistics demand is on the line, it is also judged whether it is on the transportation route.
[0029] When obtaining pending transport individuals, if the number of transport individuals in the result of the first round of screening is 0, all transport individuals in transit are taken as results and sequentially subjected to the second and third rounds of screening to obtain the transport individuals in transit as split transport individuals.
[0030] For taking individual pending means of transport or splitting individual means of transport, a score is given for the way of using each individual pending means of transport to transport the new transportation demand. A score will be generated when each individual pending means of transport is used to transport the new demand. Then recommendations are made based on the size of the score. The scores are sorted from large to small. Multiple individual means of transport with the largest scores or high scores are recommended to the service provider for scheduling control, and one of the individual means of transport with the largest score or high scores is used for transportation scheduling of the new demand. This method satisfies that one transport tool can transport the goods corresponding to the newly added transport demand; when the amount of goods required for the newly added goods is greater than the carrying capacity that can be completed by one transport tool, multiple transport tools in transit are required for transportation, so there will be split transport tools. Therefore, in the first round of screening, it is directly skipped, and all transport tools in transit are used to undergo the second and third rounds of screening to obtain split transport tools. Then, the goods transported by each split transport tool are scored, and the score of each split transport tool is obtained. The top n split transport tools with the highest scores are selected as the transportation method for the newly added goods demand and recommended to the service provider for scheduling control, where the total remaining cargo capacity of the top n split transport tools is greater than the cargo capacity of the newly added logistics goods demand. That is, the total remaining cargo capacity of the top n-1 split transport tools with the largest scores is less than the cargo capacity of the newly added logistics goods demand, while the total remaining cargo capacity of the top n split transport tools is greater than the cargo capacity of the newly added logistics goods demand. Then, the specific value of n can be determined.
[0031] When making scheduling recommendations, if the number of pending transport individuals is 0 or the number of split transport individuals is less than 2 or the total remaining cargo capacity of all split transport individuals is lower than the cargo volume of the new logistics cargo demand, it is judged that the new logistics demand cannot be met by the transport individuals in transit, and it is recommended to use idle new transport individuals for transportation scheduling, add new orders and schedule idle new transport individuals to carry out transportation scheduling for the new cargo demand.
[0032] When scoring individual transport vehicles, the key to scoring is to meet the needs of balancing time costs and profits. Only in this way can the scores given represent the balance between time and profit achieved by using this mode of transportation scheduling, thereby achieving the goal of stable and reliable tuning scheduling control. When calculating the score, the location information of each transport tool is located through the GPS or Beidou positioning information installed on each individual transport tool, and then the distance information generated by each individual transport tool in transporting the newly added logistics goods demand to the destination is calculated through the location information, and the corresponding time cost can be calculated based on the distance information; then the newly added profit information can be obtained through the order price of the newly added logistics information; then based on the time cost and newly added profit information, the score obtained by using each individual transport tool for transportation is scored, and each mode of transportation is scored using the expert database scoring method. In order to realize the expert database scoring, a comparison table information of time cost, newly added profit and expert score set up by experts is pre-built; then a neural network is used to learn the comparison table information, that is, time cost and newly added profit are used as the input of the neural network model, and expert score is used as the output of the neural network, which is input into the neural network model for training. After the training, the neural network model can be used to score and output the newly added logistics demand for each individual transport tool, and the score output meets the expert's needs for the balance between time cost and newly added profit.
[0033] After determining the individual transport vehicles to be dispatched corresponding to the new logistics demand, dispatch instructions are issued to the individual transport vehicles to be transported, and the execution status of the dispatch instructions is detected in real time and fed back to the monitoring platform, which is used to issue an alarm signal. The location information of the individual transport vehicles to be dispatched is obtained in real time based on the vehicle-mounted GPS positioning terminal, and the real-time location information is used to predict whether the dispatched transport vehicles will execute the dispatch, that is, the running trajectory of the transport vehicles is judged to be toward the starting point of the new demand. If not, an alarm reminder message is generated to send a corresponding alarm reminder instruction to the individual transport vehicle terminal.
[0034] If a signal that the dispatch cannot be executed is received from an individual transport tool, or if the monitoring determines that the dispatch control instruction is not executed, the non-execution information is recorded, and then the undetermined transport tool individual with a score after the transport tool individual that did not execute the dispatch instruction is selected as the transport tool for transporting the new logistics demand, and the dispatch instruction is sent to it and its execution result is monitored. The non-execution information includes the identity information ID of the non-executed transport tool, the reason for non-execution, etc., which provides basic data for subsequent traceability investigation.
[0035] The GPS positioning terminal installed in the individual transport tool determines whether the starting point of the new cargo demand has been reached. After reaching the starting point of the new logistics demand, the individual transport tool's stay time is counted. When the vehicle stays for more than the set time range, a reminder instruction is sent to the reminder device of the individual transport tool, and the user sends a reminder signal to urge timely transportation. By counting the progress time during the transportation process and timely monitoring and reminder, the efficiency of transportation is effectively improved, and abnormal stay events during the transportation process are avoided to affect the transportation progress.
[0036] Obviously, the specific implementation of the present invention is not limited to the above-mentioned methods. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, they are all within the protection scope of the present invention.
