Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0044] Application Overview

[0045] Most of my country's ports are hinterland ports, which are designed to meet the transportation needs of hinterland economic development. In the international market, there is a certain gap in the radiation capacity of my country's ports and the industrial radiation capacity based on the coordinated development of ports, industries and cities and the integration of port supply chains. The level of hinterland radiation capacity of ports determines the speed of economic development in inland hinterlands. Reasonable economic connection between inland and ports can effectively support port construction.

[0046] Among them, for port operators and planners, they can understand the radiation capacity of different cargo types to the hinterland based on the current port freight structure, thereby providing strong support for the adjustment of the port's collection and distribution system and port construction planning; for port operators, by integrating the port's hinterland radiation capacity and the hinterland's industrial advantages, they can explore the potential cooperation space between the port and the hinterland, while considering the land transportation system between the port and the hinterland, and further strengthen the cooperation space and value between the port and the hinterland; for the port hinterland, they can fully understand the comprehensive service level of the port, develop potential advantageous industries in a targeted manner, and promote the development of the hinterland economy. This application combines the throughput model, the rated amount model, and the system model to achieve an effective assessment of the radiation capacity of the port to the inland hinterland, and effectively carry out the targeted construction and development of subsequent ports.

[0047] Exemplary Methods

[0048] A method for evaluating the radiation capacity of a port based on geographic information data is executed by a processor. It is understandable that the processor may be a central processing unit (CPU), or other general-purpose processors, digital signal processors (DSP), application-specific integrated circuits (ASIC), field-programmable gate arrays (FPGA) or other programmable logic devices, discrete gates or transistor logic devices, discrete hardware components, etc. A general-purpose processor may be a microprocessor or the processor may be any conventional processor, etc.

[0049] Methods include:

[0050] Obtain the target port's annual container throughput in the past, and obtain the annual container throughput set; obtain the target port's past inland hinterland cargo transaction amount, and obtain the amount statistics set; perform data cleaning on the annual container throughput set and the amount statistics set; perform a quantity analysis based on the throughput model on the cleaned annual container throughput set, and perform a calculation analysis based on the rated amount model on the cleaned amount statistics set; based on the quantity analysis and the calculation analysis results, obtain the preliminary evaluation results of the target port's future radiation capacity; perform the final radiation capacity evaluation of the target port based on the preliminary evaluation results and the system model. The method of this embodiment realizes the reasonable use of the above data based on the container throughput of the previous port and the amount of transactions between the hinterland and the port, combined with the throughput model, the rated amount model and the system model, and can realize the effective evaluation of the port's radiation capacity, complete the connection between the inland hinterland and the port economy, and promote the rapid development of the port economy. It can be understood that the connection between the port and the inland hinterland is completely based on the geographical environment of the target port and the corresponding inland hinterland. Therefore, the radiation capacity of the port will be different under different geographical environments, but it does not deviate from the exemplary method in this embodiment.

[0051] The following is a detailed description of each of the above steps:

[0052] In some embodiments, the target port's annual container throughput in previous periods includes: the number of transshipment containers at the target port, the number of fixed unloaded containers at the target port, and the number of unloaded containers transferred from other ports to the target port.

[0053] In some embodiments, the amount of cargo transactions between the target port and the inland hinterland includes: the total value of cargo imported and exported from the port to the inland hinterland, the port cargo transportation cost, and the total value of cargo lost in the transportation of cargo from the hinterland to the port.

[0054] In some implementations, a throughput model-based quantitative analysis is performed on the cleaned annual container throughput set, specifically:

[0055] The annual container throughput set is classified into the first quarter throughput set ρ1, the second quarter throughput set ρ2 and the third quarter throughput set ρ3; ρ1, ρ2 and ρ3 are input into the throughput model to calculate the throughput share. It should be noted that the first quarter throughput set ρ1, the second quarter throughput set ρ2 and the third quarter throughput set ρ3 all include the number of transshipment containers at the target port, the number of fixed unloading containers at the target port and the number of unloading containers transferred from other ports to the target port.

[0056] Specifically, the throughput model is:

[0057]

[0058] Where ψ is the throughput ratio; ρ x is the throughput of the port in the corresponding quarter, x = 1, 2, 3; ρ 标 Preset standard throughput for ports.

[0059] In some implementations, a calculation analysis based on a rated amount model is performed on the cleaned amount statistics set, specifically:

[0060] Classify the amount statistics set into the first quarter amount set C 1· , the second quarter amount set C2 and the third quarter amount set C3; 1· , C2 and C3 input the rated amount model and calculate the amount achievement rate.

[0061] It should be noted that the amount of the first quarter is set C 1· , the second quarter amount set C2, and the third quarter amount set C3 both include the total value of goods imported and exported from the inland hinterland to the port, the port cargo transportation cost, and the total value of lost goods in the transportation from the hinterland to the port.

[0062] Specifically, the rated amount model is:

[0063]

[0064] Among them, φ is the compliance rate; C n is the amount set of the port in the corresponding quarter, n = 1, 2, 3; C e The preset rated amount.

[0065] In some embodiments, the preliminary evaluation result of the future radiation capacity of the target port is obtained as follows: the estimated radiation capacity of the target port every quarter combined with past data. It is understandable that the preliminary evaluation result is obtained based on past data. In other words, the evaluation result at this time is not real-time. In order to make the evaluation result more real-time or predictable, the method of this embodiment also involves a system model, specifically, including a first analysis layer, a second estimation layer and a third output layer. Among them: the first analysis layer performs deviation analysis and removal on the estimated radiation capacity of the target port in combination with the past radiation standard values ​​in the port radiation library; the second estimation layer obtains the data from the first analysis layer and performs radiation capacity analysis of the future target port; the third output layer receives the analysis data from the second estimation layer and performs the final estimated output. It is understandable that the evaluation data output by the system model is real-time, and the data is representative after being analyzed and processed by the first and second layers.

[0066] In order to better understand the method of the present application, the present application also provides a port radiation capacity assessment system. Exemplarily, the aforementioned method can be understood as a computer program, which can be divided into one or more modules, one or more modules are stored in a memory, and executed by a processor to complete the present application. One or more modules can be a series of computer program instruction segments that can complete specific functions, and the instruction segments are used to describe the execution process of the computer program in any terminal device. For example, a computer program can be divided into at least a first acquisition module, a second acquisition module, a preprocessing module, an analysis module, a preliminary estimation module and a final evaluation module, and the specific functions of each module are as follows: the first acquisition module is used to obtain the target port's past annual container throughput and obtain an annual container throughput set; the second acquisition module is used to obtain the target port's past inland hinterland cargo transaction amount and obtain an amount statistics set; the preprocessing module is used to perform data cleaning on the annual container throughput set and the amount statistics set; the analysis module is used to perform quantitative analysis based on the throughput model on the cleaned annual container throughput set, and perform computational analysis based on the rated amount model on the cleaned amount statistics set; the preliminary estimation module is used to obtain a preliminary evaluation result of the target port's future radiation capacity based on the quantitative analysis and computational analysis results; the final evaluation module is used to perform a final radiation capacity evaluation of the target port based on the preliminary evaluation result based on the system model.
