Description
Technical Field
[0001] The present invention relates to the technical field of logistics management, and in particular to a digital reservation management method for intelligent logistics capacity based on big data. Background Art
[0002] In the existing logistics capacity reservation management, most systems digitize and automate vehicle information based on technologies such as license plate recognition and RFID.
[0003] Traditional solutions generally set fixed reservation time periods, require vehicles to register in advance, and use preset rules to allocate resources. However, in actual applications, there are delays in data updates, and the on-site conditions do not completely match the system's expectations. As a result, although some vehicles that have made reservations in advance can be quickly processed into the park, vehicles that enter the park temporarily need to wait a long time. In addition, there are too many reserved vehicles during peak hours, and the system scheduling flexibility is insufficient, resulting in a very unbalanced overall operation process.
[0004] To deal with this situation, some traditional solutions generally balance the scheduling of scheduled and non-scheduled vehicles by increasing manual intervention and preset proportion control. However, this is still difficult to make up for the shortcomings of delayed data feedback and insufficient dynamic response, affecting the operational efficiency of the entire park. Therefore, a digital reservation management method for smart logistics capacity based on big data is urgently needed to alleviate the queuing chaos in the logistics park. Summary of the invention

[0096] Specifically, various sensor devices are used here to collect real-time data on vehicle entry and exit from the park, and the data is cleaned and fused through a unified big data platform. By defining the vehicle data set for the entire time period, the platform can cover vehicle information for each time period. Using the vehicle information obtained through license plate recognition, the vehicle identity and quantity at each moment are determined. Then, by counting the number of reserved vehicles in each time period, the reservation ratio is calculated to quantify the vehicle flow and reservation situation in the entire park;
[0097] The data platform ensures the timeliness and integrity of the data, and can not only reflect the vehicle entry and exit status in real time, but also dynamically capture the ratio change of reserved vehicles to non-reserved vehicles;

[0115] Where, Q s represents the real-time traffic flow pressure, m t represents the number of vehicles at the current moment, represents the average value of the number of vehicles in the whole period;
[0116] According to the traffic flow pressure, introduce an adjustment factor w s :

[0120]
[0121] Wherein, represents the reservation vehicle ratio after adjustment, ρ t represents the original reservation ratio counted in step S1, and δ1 represents the adjustment step of the reservation ratio;
[0122] Specifically, historical sample data and real-time traffic flow data are introduced here. The operation durations of reservation vehicles and non-reservation vehicles are counted, and a difference index of the operation duration is defined. With the help of the traffic flow pressure index composed of the real-time vehicle number and the full-time average value, the adjustment factor is further calculated, so as to dynamically correct the original reservation ratio. Through adaptive reservation allocation, the reservation window can be adjusted in advance during peak hours to reduce the risk of local congestion caused by too many reservation vehicles, and at the same time achieve the balance of the operation durations of reservation and non-reservation vehicles;
[0123] Step S3: Use a prediction model to comprehensively predict the vehicle entry and exit conditions in the future period, and schedule some reservation vehicles to enter the park during off-peak hours according to the prediction results;
[0124] In step S3, the steps of using a prediction model to comprehensively predict the vehicle entry and exit conditions in the future period and scheduling some reservation vehicles to enter the park during off-peak hours according to the prediction results include:

[0134] where s represents the number of vehicles scheduled in advance, r 3,t represents the number of reserved vehicles within time t, and min(·) represents the minimum value function;
[0135] Finally, the reservation ratio is updated through scheduling adjustment to achieve off-peak park entry. The formula is:
[0136]
[0137] where represents the updated off-peak park entry reservation ratio after scheduling, represents the adjusted reservation ratio in step S2, and λ represents the scheduling adjustment factor used to control the impact of the number of vehicles scheduled in advance on the reservation ratio;
[0138] Specifically, a linear prediction model is established here to predict the vehicle inflow and outflow in the future period. The predicted number of vehicles is calculated by combining the current traffic flow and the reservation ratio and compared with the preset traffic flow threshold. The prediction deviation reflects the peak risk. Based on this, the number of vehicles scheduled in advance is determined. By introducing the scheduling adjustment factor, the prediction result is converted into an actual scheduling strategy to achieve off-peak park entry for reserved vehicles. This prediction and scheduling mechanism effectively alleviates the congestion risk caused by the concentration of vehicles during peak hours and improves the balance of overall resource allocation in the park and the vehicle operation efficiency at the same time.
