Description

Technical Field

[0001] This application relates to the technical field of logistics management, and in particular, to a method, device, electronic device, and storage medium for making reservations in time slots. Background Art

[0002] In the current steel production logistics system, the supply of bulk raw materials and fuels in steel mills and the logistics distribution process of finished products face significant challenges. Due to the concentration of vehicle arrivals and the limited loading and unloading capacity, the phenomenon of unbalanced resource scheduling within the factory area frequently occurs. This imbalance is particularly evident during peak hours, where a large number of transport vehicles are forced to wait outside the factory for long periods, not only greatly reducing the job satisfaction of drivers but also causing traffic congestion around the factory area and increasing unnecessary logistics costs.

[0003] Currently, traditional logistics management models are difficult to effectively address the above challenges. On the one hand, the lack of an accurate dynamic inventory adjustment mechanism makes it impossible for inventory management to be flexibly adjusted according to real-time demand, thus affecting the overall supply chain efficiency. On the other hand, existing vehicle scheduling systems fail to fully consider the traffic flow differences during different time periods, resulting in unreasonable resource allocation and low loading and unloading efficiency. Therefore, during the logistics peak period, vehicle congestion has become the norm, seriously affecting the logistics operation efficiency and the economic benefits of enterprises.

[0038] In the related art, it is impossible to balance the loading and unloading requirements in logistics management.

[0039] To solve the above technical problems, the present application provides a time-slot reservation method, device, electronic device, and storage medium. The following elaborates in detail on the implementation details of the technical solution of the embodiments of the present application.

[0040] Please refer to Figure 2 , Figure 2 which shows a schematic flow diagram of the time-slot reservation method according to an embodiment of the present application. As Figure 2 shown, in an exemplary embodiment, the time-slot reservation method at least includes steps S210 to S230, which are introduced in detail as follows:

[0041] Step S210, obtain the reservation management information of the warehouse.

[0042] Among them, the reservation management information includes the available reservation inventory, the current actual inventory, the current theoretical inventory, and the quantity of signed-in but unloaded of a material item in the current time slot to be reserved.

[0043] In an embodiment of the present application, the current time slot to be reserved is used to represent that the current time is within a time slot to be reserved.

[0044] In an embodiment of the present application, the material item is used to represent the information of a material, including at least one of the material number, name, specification, quantity, and supplier information.

[0045] In an embodiment of the present application, the current theoretical inventory, the current actual inventory, and the quantity of signed-in but unloaded can be applied to the loading management of the material. The type of the material includes bar and wire, a long strip steel product.

[0046] In an embodiment of the present application, the determination of the current theoretical inventory includes: determining the previous inventory value by adding the previous actual inventory and the previous rolling plan quantity of the material item in the previous time slot to be reserved; determining the current theoretical inventory as the difference between the previous inventory value and the previous planned usage quantity of the material item in the previous time slot to be reserved; among them, the reservation management information further includes the previous actual inventory, the previous rolling plan quantity, and the previous planned usage quantity.

[0047] In an embodiment of the present application, the current theoretical inventory = previous actual inventory + previous rolling plan quantity - previous planned usage quantity.

[0048] In an embodiment of the present application, the previous planned usage quantity is used to represent the deduction quantity corresponding to the theoretical available reservation quantity of the material item in the previous time slot to be reserved after reservation. Among them, the deduction quantity at least includes the quantity deducted by manual editing and the quantity deducted by reservation. The quantity deducted by manual editing, such as the quantity shipped by railway.

[0049] In an embodiment of the present application, the current actual inventory is obtained from the warehouse at the start time of the current time slot to be reserved, and the previous actual inventory is obtained from the warehouse at the start time of the previous time slot to be reserved.

[0050] In an embodiment of the present application, the quantity of signed-in but unloaded is used to characterize the quantity that has been signed in, is in the to-be-reserved period before the current to-be-reserved period, and has not been fully loaded.

[0051] In an embodiment of the present application, signing in is used to control entry into a preset loading and unloading location.

[0052] Step S220: Determine an inventory deviation value based on the current actual inventory, the current theoretical inventory, and the quantity of signed-in but unloaded.

[0053] In an embodiment of the present application, determining the inventory deviation value based on the current actual inventory, the current theoretical inventory, and the quantity of signed-in but unloaded includes: determining the difference between the current actual inventory and the current theoretical inventory as the initial deviation value; and determining the difference between the initial deviation value and the quantity of signed-in but unloaded as the inventory deviation value.

[0054] In an embodiment of the present application, the inventory deviation value = current actual inventory - current theoretical inventory - quantity of signed-in but unloaded.

[0055] Step S230: Compare the inventory deviation value with a preset inventory threshold to obtain a deviation comparison result, and update the reservable inventory by increasing or decreasing it according to the deviation comparison result.

[0056] In an embodiment of the present application, if the inventory deviation value is greater than or equal to the preset inventory threshold, the reservable inventory will be increased according to the inventory deviation value; if the inventory deviation value is less than the preset inventory threshold, the reservable inventory will be deducted according to the inventory deviation value.

[0057] In an embodiment of the present application, the preset inventory threshold can be set to 0.

[0058] In an embodiment of the present application, in the application of steel plant logistics, through dynamic deviation correction, an accurate match between the reservable inventory and the actual reserved quantity is achieved, avoiding over-reservation or resource waste caused by inventory errors, and ensuring the real-time effectiveness of vehicle reservation.

[0059] In an embodiment of the present application, updating the reservable inventory by increasing or decreasing it according to the deviation comparison result includes: if the inventory deviation value is greater than or equal to the preset inventory threshold, adding the inventory deviation value and the theoretical reservable quantity of material items before the current to-be-reserved period to the theoretical reservable quantity of the current to-be-reserved period; if the inventory deviation value is less than the preset inventory threshold, deducting the theoretical reservable quantity of material items from the current to-be-reserved period to subsequent to-be-reserved periods in sequence according to the inventory deviation value; wherein, the reservable inventory includes the theoretical reservable quantity corresponding to each to-be-reserved period.

[0060] In one embodiment of the present application, the determination of the theoretical reservable quantity includes: if the current time is the planning time, the sum of the last actual inventory and the rolling plan quantity of the first reservable time period is determined as the theoretical reservable quantity of the first reservable time period in the current reservation cycle, and the rolling plan quantities corresponding to the remaining reservable time periods in the current reservation cycle are determined as the theoretical reservable quantities of the remaining reservable time periods; if the actual reservation time period is the current reservable time period, the theoretical reservable quantity of the material item is deducted from the actual reservation time period to the subsequent reservable time periods in sequence according to the newly added first reservation quantity; if the actual reservation time period is a reservable time period after the current reservable time period, the theoretical reservable quantity of the material item is deducted from the actual reservation time period to the previous reservable time periods in sequence according to the newly added first reservation quantity; if it is detected that there is a reservation cancellation in a reservable time period, the second reservation quantity of the reservation cancellation is added to the theoretical reservable quantity of the material item in the reservable time period; wherein, the reservation management information includes the last actual inventory, the first reservation quantity, the second reservation quantity, the actual reservation time period, and the rolling plan quantities corresponding to each reservable time period, and the last actual inventory is used to represent the actual inventory quantity of the material item after the end of the previous reservation cycle.

[0061] In one embodiment of the present application, the reservation cycle can be set to 24 hours, and the planning time can be set to 8:00 am every day to clear the theoretical reservable quantity of the previous reservation cycle and generate the theoretical reservable quantity of the current reservation cycle.

[0062] In one embodiment of the present application, it can be set that 2 hours is one reservable time period.

[0063] In one embodiment of the present application, please refer to Figure 3 , Figure 3 shows a display schematic diagram of the theoretical reservable quantity according to one embodiment of the present application. As Figure 3 shown, taking 4 reservable time periods as an example in the present application, in the planning stage, the theoretical reservable quantity of the first reservable time period is 200 + 100 tons, and the theoretical reservable quantities of the second to fourth reservable time periods are 100 tons; 200 tons is the last actual inventory, and 100 tons is the rolling plan quantity; wherein, this is only an example, and the present application does not make any restrictions on the units and actual values of the theoretical reservable quantity and the rolling plan quantity.

[0064] In one embodiment of the present application, the rolling plan quantities of different reservable time periods can be the same or different.

[0065] In one embodiment of the present application, please refer to Figure 4 , Figure 4 shows a deduction schematic diagram of the theoretical reservable quantity according to one embodiment of the present application. As Figure 4As shown, the dashed box is used to represent the current time period to be reserved. The first reserved quantity corresponding to the second time period to be reserved is 150 tons. If the theoretically reservable quantity in the second time period to be reserved is not enough to deduct, the deduction quantity is supplemented from the first time period to be reserved. After the deduction is completed, the latest theoretically reservable quantity for each time period to be reserved is 250 tons, 0 tons, 100 tons, and 100 tons in sequence; then the first reserved quantity in the first time period to be reserved is 120 tons, and the theoretically reservable quantity meets the deduction. After the deduction is completed, the latest theoretically reservable quantity for each time period to be reserved is 130 tons, 0 tons, 100 tons, and 100 tons in sequence.

[0066] In an embodiment of the present application, please refer to Figure 5 , Figure 5 which shows a rectification schematic diagram of the theoretically reservable quantity according to an embodiment of the present application. As Figure 5 shown, the dashed box is used to represent the current time period to be reserved. The theoretically reservable quantity for each time period to be reserved is 130 tons, 0 tons, 100 tons, and 100 tons. The current theoretical inventory = 200 + 100 - 120 = 180 tons. It is obtained that the current actual inventory is 220 tons, and the quantity of signed-in but not loaded is 30 tons. The inventory deviation value = 220 - 180 - 30 = 10 tons > 0. Then 10 tons and 130 tons of the first time period to be reserved are accumulated to the theoretically reservable quantity of the current time period to be reserved. The theoretically reservable quantity for each time period to be reserved is 0 tons, 140 tons, 100 tons, and 100 tons in sequence.

[0067] In an embodiment of the present application, to improve the success rate and timeliness of reservation, the present application designs a reservation cancellation and early reminder function. During each time period to be reserved, the remaining theoretical reservation quantity is monitored in real time. If the reservation is cancelled, the cancelled second reservation quantity is automatically released to the remaining reservation quantities of this time period to be reserved to realize the update of the theoretical reservation quantity. After the reservation is successful, a text message is sent to the reservation terminal in real time to remind the user and remind the user to arrive according to the actual reservation time in advance.

[0068] In an embodiment of the present application, please refer to Figure 6 , Figure 6 which shows a rectification schematic diagram of the theoretically reservable quantity according to another embodiment of the present application. As Figure 6As shown, the dashed box is used to represent the current time period to be reserved. During the current time period to be reserved, the first reservation quantity corresponding to the third time period to be reserved is 200 tons. If the theoretical reservable quantity of the third time period to be reserved is not sufficient for deduction, then the theoretical reservable quantity of the second time period to be reserved is deducted. After the deduction is completed, the latest theoretical reservable quantities of each time period to be reserved are 0 tons, 40 tons, 100 tons, and 100 tons in sequence. When the current time is at the start time of the third time period to be reserved, the current theoretical inventory = 220 + 100 - 150 = 170 tons. The current actual inventory is obtained as 200 tons, and the quantity of signed-in but unloaded vehicles is 80 tons. The inventory deviation value = 200 - 170 - 80 = -50 tons < 0. Then, the theoretical reservable quantity of the material item is deducted from the current time period to be reserved to the subsequent time periods to be reserved in sequence. After the deduction is completed, the latest theoretical reservable quantities of each time period to be reserved are 0 tons, 0 tons, 0 tons, and 90 tons in sequence.

[0069] In an embodiment of the present application, during the rectification process of the theoretical reservable quantity, the time-sharing balance function can be realized to balance the theoretical reservable quantities of each time period to be reserved.

[0070] In an embodiment of the present application, please refer to Figure 7 , Figure 7 shows a schematic flow diagram of dynamic inventory rectification according to an embodiment of the present application. As Figure 7 shown, at the planned time, obtain the rolling plan quantity corresponding to the current reservation cycle: for example, obtain the rolling plan quantity for the next 24 hours at 8 am; obtain the current actual inventory of each material item: at the start time of each time period to be reserved, obtain the current actual inventory of each material item at each loading point; combine the current actual inventory and the rolling plan quantity to form the sub-period inventory of each loading point and each material item: the sub-period inventory is the theoretical reservable quantity of each time period to be reserved; dynamically adjust the reservable inventory of each loading point and each material item: increase or decrease the reservable inventory according to the deviation comparison result. Among them, the increase in the reservable inventory also includes the quantity increased by manual editing and the quantity of reservation cancellation. The quantity increased by manual editing includes the return quantity, and the quantity of reservation cancellation includes user cancellation of reservation, deletion of the waybill to be reserved, failure to sign in within the time limit, and failure to enter the factory within the time limit. The decrease in the reservable inventory also includes the quantity deducted by manual editing and the quantity of user completed reservation.

[0071] In an embodiment of the present application, after obtaining the reservation management information of the warehouse, it further includes: determining the maximum loading quantity of the loading point or the maximum unloading quantity of the unloading point as the restricted reservable quantity of a time period to be reserved; if the reserved logistics type is loading, determining the rolling plan quantity in the reservation management information as the priority deduction quantity of the theoretical reservable quantity; if the reserved logistics type is unloading, determining the unloading plan in the reservation management information as the priority deduction quantity of the unloading reservable quantity; where the reservation management information further includes the reserved logistics type and the actual reservation quantity.

[0072] In one embodiment of the present application, according to the maximum operating capacity of each loading or unloading point, the limit of the available reservation quantity for each pending reservation period is set to ensure that the actual reservation quantity for each pending reservation period does not exceed the maximum operating capacity. Among them, the maximum operating capacity includes the highest loading quantity of the loading point and the highest unloading quantity of the unloading point.

[0073] In one embodiment of the present application, in the reservation of bulk raw fuels and materials, the unloading plan corresponding to a reservation cycle is divided into multiple pending reservation periods, and the available reservation quantity for unloading in the pending reservation periods is evenly distributed.

[0074] In one embodiment of the present application, the present application ensures the balanced distribution of vehicles within each reservation cycle through a periodic reset reservation mechanism, avoids the accumulation of vehicles across cycles, effectively reduces the congestion problem in the plant area, and optimizes the resource utilization rate.

[0075] In one embodiment of the present application, by restricting the available reservation quantity in combination with the maximum operating capacity of actual production, the actual reservation quantity is dynamically adjusted, making the resource allocation more flexible, and reducing resource waste and scheduling imbalance.

[0076] In one embodiment of the present application, after obtaining the reservation management information of the warehouse, it further includes: if the reserved material type is a preset material type, the pending reservation period corresponding to the preset first period is determined as the material exclusive period; if the reserved supplier category is a preset supplier category, the pending reservation period corresponding to the preset second period is determined as the supplier exclusive period; wherein, the preset first period and the preset second period are the same or different, the number of the preset first periods is at least one, the number of the preset second periods is at least one, and the reservation management information further includes the reserved material type and the reserved supplier category.

[0077] In one embodiment of the present application, in the reservation of bulk raw fuels and materials, hierarchical management is implemented according to the material type and the supplier category. For example, a supplier exclusive period is set for the materials of the preset supplier category to ensure that the vehicles of key suppliers can enter the plant unobstructed; for different material types, their respective available reservation periods are set respectively to avoid resource conflicts of multiple materials in the same period. It ensures the reasonable allocation of resources for different materials and suppliers, and is especially applicable to the complex scheduling requirements of the scenarios with multiple suppliers and multiple materials in steel plants.

[0078] In one embodiment of the present application, please refer to Figure 8 , Figure 8 shows a schematic flow chart of general unloading reservation according to an embodiment of the present application. As Figure 8As shown, receive the purchase waybill; read the configuration of whether the material needs to be reserved: by default, materials without configuration do not need to be reserved. If the material needs to be reserved, enter the step of sending a text message to remind the driver to make a reservation on the reservation terminal. If the material does not need to be reserved, enter the step of recording that the purchase waybill does not need to be reserved and the reservation terminal displays that it does not need to be reserved; send a text message to remind the user to make a reservation on the reservation terminal: when the configuration of a material changes from not needing to be reserved to needing to be reserved, the received purchase waybill does not need to be changed; record that the purchase waybill does not need to be reserved and the reservation terminal displays that it does not need to be reserved; select the period to be reserved to complete the reservation (the reservation can be cancelled): select the period to be reserved to obtain the preselected reservation period; whether the vehicle fails to check in overtime: if the vehicle fails to check in overtime, enter the step of cancelling the reservation and releasing the available reservation quantity and number of vehicles for unloading. If the vehicle does not fail to check in overtime, enter the user check-in step; cancel the reservation and release the available reservation quantity and number of vehicles for unloading; user check-in; if checking in n minutes in advance of the actual reservation period, it is a normal check-in.
