[0001] The present application relates to the technical field of logistics, and particularly to a method, device, product and medium for allocating transport vehicles. Background Art

[0002] At present, with the increasing attention to the rational utilization of land resources in various industries, intensive warehousing technology has received extensive attention. Intensive automated stereoscopic warehouses such as four-way shuttle warehouses have emerged as the times require. Such intensive automated stereoscopic warehouses can not only improve space utilization rate, generate greater efficiency in a limited space, but also improve operation efficiency, meeting the requirements of high-efficiency operation with low-cost investment.

[0003] In practical applications, in an intensive automated stereoscopic warehouse, it is usually necessary to use transport vehicles to transport the boxes corresponding to the stock keeping unit (SKU) required by each outbound vehicle to the corresponding outbound vehicle for loading. When loading each outbound vehicle, the boxes need to meet the requirement that the boxes of the same SKU are placed continuously. Under the premise of meeting the requirement that the boxes of the same SKU are placed continuously when loading each outbound vehicle, how to reasonably allocate transport vehicles is a problem that needs to be solved currently. Summary of the Invention

[0022] In order to make the purpose, technical solutions and beneficial effects of the present application clearer and more understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present application.

[0023] To facilitate better understanding of the present application by those skilled in the art, the technical terms involved in the present application will be briefly introduced below.

[0024] ---SKU is the smallest measurement unit for inventory in and out control. For example, if a commodity has multiple colors and each color corresponds to one SKU, in the embodiment of the present application, each SKU can use boxes, pallets, etc. as the units for in and out of the warehouse.

[0025] ---The sequence of SKUs to be shipped out of the whole warehouse is a sequence representing the shipping out order of all currently to-be-shipped-out SKUs in the target warehouse, which is obtained by sorting all currently to-be-shipped-out SKUs of each outbound vehicle based on the SKU outbound cost of all currently to-be-shipped-out SKUs of each outbound vehicle on the premise that the cost of shipping out the whole warehouse is minimized and the resources for shipping out the whole warehouse are not idle.

[0026] ---The resources for shipping out the whole warehouse are the transportation resources for outbound picking in the target warehouse. In the embodiment of the present application, the resources for shipping out the whole warehouse include but are not limited to transport vehicles, full-pallet outbound stations, piece-picking outbound stations, etc.

[0027] ---The cost of shipping out the whole warehouse is a parameter representing the overall cost to be paid when all currently to-be-shipped-out SKUs in the target warehouse are shipped out, which is determined based on various outbound cost measurement indicators such as the resources and outbound time consumed by all currently to-be-shipped-out SKUs in the target warehouse for shipping out.

[0028] ---The SKU outbound cost is a parameter representing the cost to be paid for the outbound of the to-be-shipped-out SKU, which is determined based on various outbound cost measurement indicators such as the resources and outbound time consumed by the to-be-shipped-out SKU for outbound.

[0029] After introducing the technical terms involved in this application, next, the application scenarios and design concepts of the embodiments of this application will be briefly introduced.

[0030] With the development of intelligent technologies such as the Internet of Things, artificial intelligence, and big data, the demand for using these intelligent technologies to transform and upgrade the traditional logistics industry has become stronger, and intelligent logistics (Intelligent Logistics System) has become a research hotspot in the logistics field. Intelligent logistics uses artificial intelligence, big data, and various Internet of Things devices and technologies such as information sensors, radio frequency identification technology, and global positioning system (GPS), and is widely used in basic activity links such as material transportation, warehousing, distribution, packaging, loading and unloading, and information services to achieve intelligent analysis and decision-making, automated operation, and high-efficiency optimization management in the material management process. Among them, Internet of Things technology includes sensing devices, RFID technology, laser infrared scanning, infrared induction recognition, etc. The Internet of Things can effectively connect the materials in logistics with the network, can monitor the materials in real time, and can also sense environmental data such as the humidity and temperature of the warehouse to ensure the storage environment of the materials. Through big data technology, all data in logistics can be sensed, collected, uploaded to the data layer of the information platform, and operations such as filtering, mining, and analyzing the data can be performed, and finally accurate data support can be provided for business processes (such as transportation, warehousing, storage, picking, packaging, sorting, outbound, inventory, distribution, etc.). The application directions of artificial intelligence in logistics can be roughly divided into two types: 1) using intelligent devices empowered by AI technology, such as driverless trucks, AGVs, AMRs, forklifts, shuttle cars, stacker cranes, driverless delivery vehicles, drones, service robots, robotic arms, intelligent terminals, etc. to replace some manual labor; 2) improving manual efficiency through software systems driven by technologies or algorithms such as computer vision, machine learning, and operations research optimization, such as transportation equipment management systems, warehouse management, equipment scheduling systems, order allocation systems, etc. With the research and progress of intelligent logistics, this technology has been applied in many fields, such as retail and e-commerce, electronics, tobacco, medicine, industrial manufacturing, shoes and clothing, textiles, food, etc.

[0031] The intensive automated stereoscopic warehouse is an automated storage and retrieval warehouse based on intelligent logistics. Intensive automated stereoscopic warehouses such as four-way shuttle car warehouses can not only improve space utilization and generate greater efficiency in a limited space, but also improve operation efficiency and meet the requirements of high-efficiency operation with low-cost investment. At present, through the capacity allocation layer in the warehouse control system, a capacity allocation method is used to allocate the capacity of transport vehicles, elevators, pallet lines, box lines, etc. In actual applications, the allocation of transport vehicles by the capacity allocation layer is a key factor in measuring the resource utilization rate of the target warehouse, and the current transport vehicle allocation methods usually have problems such as unreasonable resource allocation and low resource utilization rate.

[0032] To this end, the embodiments of the present application improve the transport vehicle allocation method in the transport capacity allocation layer. That is, after determining the information of the idle transport vehicles corresponding to the current target floor in the target warehouse, based on the sequence of SKUs to be shipped out of the entire warehouse corresponding to the target warehouse currently, determine the current emergency degree of shipment for each SKU to be shipped out on the target floor. After determining the SKUs to be shipped out urgently corresponding to the target floor currently based on the current emergency degree of shipment for each SKU to be shipped out on the target floor, based on the information of the idle transport vehicles corresponding to the target floor currently, allocate idle transport vehicles to the SKUs to be shipped out urgently corresponding to the target floor currently. In this way, by using the sequence of SKUs to be shipped out of the entire warehouse corresponding to the target warehouse currently to determine the current emergency degree of shipment for each SKU to be shipped out on the target floor, the accuracy of the current emergency degree of shipment for each SKU to be shipped out on the target floor finally determined can be improved. Thus, when determining the SKUs to be shipped out urgently corresponding to the target floor currently based on the current emergency degree of shipment for each SKU to be shipped out on the target floor, the accuracy of the SKUs to be shipped out urgently corresponding to the target floor currently finally determined can be improved. Furthermore, when allocating idle transport vehicles to the SKUs to be shipped out urgently corresponding to the target floor currently based on the information of the idle transport vehicles corresponding to the target floor currently, while meeting the requirement that the boxes of the same SKU are placed continuously when loading each outbound vehicle, the resource utilization rate of the target warehouse can be improved.

[0033] After introducing the application scenario and design concept of the embodiments of the present application, the technical solutions provided by the embodiments of the present application will be described in detail below.

[0034] The embodiments of the present application provide a method for allocating transport vehicles. This method for allocating transport vehicles can be applied to electronic devices such as computers and servers configured with a warehouse control system. Refer to Figure 1 As shown, the general process of the method for allocating transport vehicles provided by the embodiments of the present application is as follows:

[0035] Step 101: Determine the information of the idle transport vehicles corresponding to the current target floor in the target warehouse.

[0036] In one embodiment, the target floor can be each floor in the target warehouse, and the electronic device can determine the identification, quantity, and other information of the idle transport vehicles corresponding to each floor in the target warehouse.

[0037] In another embodiment, the target floor can also be a specified floor in the target warehouse, such as the first floor in the target warehouse, etc. The electronic device can determine the identification, quantity, and other information of the idle transport vehicles corresponding to the specified floor in the target warehouse.

[0038] Step 102: Based on the full-warehouse SKUs to be shipped out corresponding to the target warehouse currently, determine the current emergency shipment degree corresponding to each SKU to be shipped out on the target floor.

[0039] In one embodiment, the emergency shipment degree can be an emergency shipment score. The electronic device can determine the current emergency shipment score corresponding to each SKU to be shipped out on the target floor as the emergency shipment degree based on the full-warehouse SKUs to be shipped out corresponding to the target warehouse currently.

[0040] In another embodiment, the emergency shipment degree can also be an emergency shipment level. The electronic device can determine the current emergency shipment level corresponding to each SKU to be shipped out on the target floor as the emergency shipment degree based on the full-warehouse SKUs to be shipped out corresponding to the target warehouse currently.

[0041] Step 103: Based on the current emergency shipment degree corresponding to each SKU to be shipped out on the target floor, determine the SKUs to be shipped out urgently corresponding to the target floor currently.

[0042] In one embodiment, when the emergency shipment degree is an emergency shipment score, the electronic device can select the SKUs to be shipped out with an emergency shipment score not lower than the score threshold from the SKUs to be shipped out on the target floor as the SKUs to be shipped out urgently corresponding to the target floor currently based on the current emergency shipment scores corresponding to each SKU to be shipped out on the target floor, or can also select the SKU to be shipped out with the highest emergency shipment score from the SKUs to be shipped out on the target floor as the SKUs to be shipped out urgently corresponding to the target floor currently.

[0043] In another embodiment, when the emergency shipment degree is an emergency shipment level, the electronic device can select the SKU to be shipped out with the highest emergency shipment level from the SKUs to be shipped out on the target floor as the SKUs to be shipped out urgently corresponding to the target floor currently based on the current emergency shipment levels corresponding to each SKU to be shipped out on the target floor.

[0044] Step 104: Based on the information of the idle transport vehicles corresponding to the target floor currently, allocate idle transport vehicles to the SKUs to be shipped out urgently corresponding to the target floor currently.

[0045] In practical applications, when the electronic device executes Step 104, there may be but are not limited to the following three situations:

[0046] The first situation: The number of idle transport vehicles is equal to the number of SKUs to be shipped out urgently corresponding to the target floor currently.

[0047] In this case, the electronic device can allocate an idle transport vehicle to each emergency outbound SKU corresponding to the current target floor based on the information of the idle transport vehicles corresponding to the current target floor.

[0048] The second case: The number of idle transport vehicles is less than the number of emergency outbound SKUs corresponding to the current target floor.

[0049] In this case, the electronic device can select the same number of emergency outbound SKUs as the number of idle transport vehicles from the emergency outbound SKUs corresponding to the current target floor, allocate an idle transport vehicle to each selected emergency outbound SKU based on the information of the idle transport vehicles corresponding to the current target floor, and further use the unselected emergency outbound SKUs among the emergency outbound SKUs corresponding to the current target floor as the SKUs to be outbound in the target warehouse for the next round of transport vehicle allocation.

[0050] The third case: The number of idle transport vehicles is greater than the number of emergency outbound SKUs corresponding to the current target floor.

[0051] In this case, the electronic device can allocate an idle transport vehicle to each emergency outbound SKU corresponding to the current target floor based on the information of the idle transport vehicles corresponding to the current target floor, and further use the remaining idle transport vehicles as the idle transport vehicles for the next round of transport vehicle allocation for transport vehicle allocation.

[0052] In the embodiments of the present application, by using the sequence of the SKUs to be outbound in the entire warehouse corresponding to the current target warehouse to determine the current emergency outbound degree of each SKU to be outbound on the target floor, and based on the current emergency outbound degree of each SKU to be outbound on the target floor, determining the emergency outbound SKUs corresponding to the current target floor for idle transport vehicle allocation, not only can the requirement that boxes of the same SKU be continuously placed when loading each outbound vehicle be met, but also the reasonable allocation and full utilization of the idle transport vehicles in the target warehouse can be realized.

[0053] In specific implementation, in one embodiment, taking the emergency outbound degree as the emergency outbound level as an example, when the electronic device determines the current emergency outbound degree of each SKU to be outbound on the target floor based on the sequence of the SKUs to be outbound in the entire warehouse corresponding to the current target warehouse, the following methods can be used but are not limited to:

[0054] First, the electronic device determines the subsequence of the SKUs to be outbound corresponding to the current target floor based on the sequence of the SKUs to be outbound in the entire warehouse corresponding to the current target warehouse. Specifically, the electronic device can determine the subsequence of the SKUs to be outbound corresponding to the current target floor based on the arrangement position information of each SKU to be outbound corresponding to the current target floor in the sequence of the SKUs to be outbound in the entire warehouse.

[0055] Then, the electronic device segments the to-be-outbound SKU subsequence corresponding to the current target floor according to the quantity of the emergency outbound levels, obtains each to-be-outbound SKU sequence segment, and sequentially sets each to-be-outbound SKU sequence segment to the corresponding emergency outbound level in the order from the highest to the lowest of each emergency outbound level; wherein, the emergency outbound levels of the to-be-outbound SKUs in the same to-be-outbound SKU sequence segment are the same.

[0056] Finally, the electronic device determines the current emergency outbound degree corresponding to each to-be-outbound SKU on the target floor based on the current emergency outbound level corresponding to each to-be-outbound SKU on the target floor.

[0057] In another embodiment, taking the emergency outbound degree as the emergency outbound score as an example, when the electronic device determines the current emergency outbound degree corresponding to each to-be-outbound SKU on the target floor based on the whole-warehouse to-be-outbound SKU sequence corresponding to the current target warehouse, the following methods can be used but are not limited to:

[0058] First, the electronic device determines the to-be-outbound SKU subsequence corresponding to each outbound vehicle currently based on the whole-warehouse to-be-outbound SKU sequence. Specifically, for each outbound vehicle, the electronic device can determine the to-be-outbound SKU subsequence corresponding to the outbound vehicle currently based on the arrangement position information of each to-be-outbound SKU corresponding to the outbound vehicle currently in the whole-warehouse to-be-outbound SKU sequence.

[0059] Then, for each to-be-outbound SKU on the target floor, the electronic device determines the current emergency outbound score corresponding to the to-be-outbound SKU based on the arrangement position information of the to-be-outbound SKU in the to-be-outbound SKU subsequence corresponding to each outbound vehicle currently.

[0060] Finally, the electronic device determines the current emergency outbound degree corresponding to each to-be-outbound SKU on the target floor based on the current emergency outbound score corresponding to each to-be-outbound SKU on the target floor.

[0061] In the embodiment of the present application, by using the arrangement position information of each to-be-outbound SKU on the target floor in the to-be-outbound SKU subsequence corresponding to each outbound vehicle currently to determine the current emergency outbound score corresponding to each to-be-outbound SKU on the target floor, not only can the accuracy of the current emergency outbound score corresponding to each to-be-outbound SKU on the target floor determined be improved, but also the total outbound of the same to-be-outbound SKU in each outbound vehicle can be realized, and thus the outbound throughput of the target warehouse can be improved.

[0062] In specific implementation, for each SKU to be shipped out on the target floor, when the electronic device determines the current emergency shipping-out score corresponding to the SKU to be shipped out based on the arrangement position information of the SKU to be shipped out in the subsequence of SKUs to be shipped out currently corresponding to each outbound vehicle, it can first determine the target outbound vehicles corresponding to the SKU to be shipped out, and then, respectively based on the arrangement position information of the SKU to be shipped out in the subsequence of SKUs to be shipped out corresponding to each target outbound vehicle, determine the emergency shipping-out sub-scores corresponding to the SKU to be shipped out for each target outbound vehicle. Finally, based on the emergency shipping-out sub-scores corresponding to the SKU to be shipped out, determine the current emergency shipping-out score corresponding to the SKU to be shipped out.

[0063] In practical applications, there can be different outbound picking methods for the SKUs to be shipped out, such as full-pallet picking and piece-picking. For different outbound picking methods, the specific methods for determining the emergency shipping-out sub-scores are different. Based on this, in one embodiment, the emergency shipping-out sub-score can include the emergency shipping-out sub-score under the full-pallet picking method. In this case, for each SKU to be shipped out on the target floor, after the electronic device determines the target outbound vehicles corresponding to the SKU to be shipped out, it can respectively determine the emergency shipping-out sub-scores corresponding to the SKU to be shipped out for each target outbound vehicle based on the arrangement position information of the SKU to be shipped out in the subsequence of SKUs to be shipped out corresponding to each target outbound vehicle. Specifically, for each target outbound vehicle, the electronic device can determine the emergency shipping-out sub-score corresponding to the SKU to be shipped out for the target outbound vehicle under the full-pallet picking method based on the total number of pallets required for all the SKUs to be shipped out before the SKU to be shipped out in the subsequence of SKUs to be shipped out currently corresponding to the target outbound vehicle, the number of pallets required for the SKU to be shipped out, the constant parameter of the full-pallet picking method, and the current capacity of the pallet line. For example, the electronic device can use the following formula (1) to determine the emergency shipping-out sub-score corresponding to the SKU to be shipped out for the target outbound vehicle under the full-pallet picking method;

[0064] score zt =e^(-a zt *ahead zt )*actual zt

[0065] actual zt =min(demand zt ,capacity zt ) …… formula (1)

[0066] Among them, score zt represents the emergency shipping-out sub-score corresponding to the SKU to be shipped out for the target outbound vehicle under the full-pallet picking method, a zt represents the constant parameter of the full-pallet picking method, aheadzt The total number of pallets required for all the to-be-outbound SKUs before the to-be-outbound SKU corresponding to the target outbound vehicle, demand zt The number of pallets required for this to-be-outbound SKU, capacity zt Characterize the current capacity of the pallet line.

[0067] In another embodiment, the emergency outbound sub-score may further include the emergency outbound sub-score in the case of piece-picking. In this case, for each to-be-outbound SKU on the target floor, after the electronic device determines the corresponding target outbound vehicles for this to-be-outbound SKU, it can respectively determine the emergency outbound sub-score of this to-be-outbound SKU corresponding to each target outbound vehicle based on the arrangement position information of this to-be-outbound SKU in the to-be-outbound SKU subsequence corresponding to each target outbound vehicle. Specifically, for each target outbound vehicle, the electronic device can determine the emergency outbound sub-score of this to-be-outbound SKU corresponding to the target outbound vehicle in the case of piece-picking based on the total number of boxes of all the to-be-outbound SKUs before this to-be-outbound SKU in the to-be-outbound SKU subsequence currently corresponding to the target outbound vehicle, the number of boxes of this to-be-outbound SKU, the constant parameter of the piece-picking method, and the current capacity of the box line. For example, the electronic device can use the following formula (2) to determine the emergency outbound sub-score of this to-be-outbound SKU corresponding to the target outbound vehicle in the case of piece-picking;

[0068] score cl = e^(-a cl *ahead cl )*actual cl

[0069] actual cl = min(demand cl , capacity cl )...... Formula (2)

[0070] Among them, score cl Characterize the emergency outbound sub-score of this to-be-outbound SKU corresponding to the target outbound vehicle in the case of piece-picking, a cl Characterize the constant parameter of the piece-picking method, ahead cl Characterize the total number of boxes required for all the to-be-outbound SKUs before this to-be-outbound SKU in the to-be-outbound SKU subsequence currently corresponding to the target outbound vehicle, demand cl Characterize the number of boxes required for this to-be-outbound SKU, capacity cl Characterize the current capacity of the box line.

[0071] In another embodiment, the emergency outbound sub-score may further include the emergency outbound sub-score in the full-pallet picking mode and the emergency outbound sub-score in the piece-picking mode; in this case, for each SKU to be outbound on the target floor, after the electronic device determines the corresponding target outbound vehicles for the SKU to be outbound, it can respectively determine the emergency outbound sub-score of the SKU to be outbound corresponding to each target outbound vehicle in the full-pallet picking mode and the emergency outbound sub-score of the SKU to be outbound corresponding to each target outbound vehicle in the piece-picking mode based on the arrangement position information of the SKU to be outbound in the sub-sequence of SKUs to be outbound corresponding to each target outbound vehicle. The specific determination method is the same as the above determination method, and the repeated parts will not be elaborated again.

[0072] Further, for each SKU to be outbound on the target floor, after the electronic device respectively determines the emergency outbound sub-score of the SKU to be outbound corresponding to each target outbound vehicle based on the arrangement position information of the SKU to be outbound in the sub-sequence of SKUs to be outbound corresponding to each target outbound vehicle, it can determine the current emergency outbound score corresponding to the SKU to be outbound based on the respective emergency outbound sub-scores corresponding to the SKU to be outbound. Specifically, the electronic device can determine the sum value of the respective emergency outbound sub-scores corresponding to the SKU to be outbound as the current emergency outbound score corresponding to the SKU to be outbound.

[0073] In practical applications, in one embodiment, when the emergency outbound sub-score includes the emergency outbound sub-score in the full-pallet picking mode, correspondingly, the emergency outbound score includes the emergency outbound score in the full-pallet picking mode; in this case, for each SKU to be outbound on the target floor, the electronic device can determine the sum value of the respective emergency outbound sub-scores corresponding to the SKU to be outbound in the full-pallet picking mode as the current emergency outbound score corresponding to the SKU to be outbound.

[0074] In another embodiment, when the emergency outbound sub-score includes the emergency outbound sub-score in the piece-picking mode, correspondingly, the emergency outbound score includes the emergency outbound score in the piece-picking mode; in this case, for each SKU to be outbound on the target floor, the electronic device can determine the sum value of the respective emergency outbound sub-scores corresponding to the SKU to be outbound in the piece-picking mode as the current emergency outbound score corresponding to the SKU to be outbound.

[0075] In another embodiment, when the emergency outbound sub-score includes the emergency outbound sub-score in the full-pallet picking mode and the emergency outbound sub-score in the piece-picking mode, correspondingly, the emergency outbound score includes the emergency outbound score in the full-pallet picking mode and the emergency outbound score in the piece-picking mode; in this case, for each SKU to be out of the warehouse on the target floor, the electronic device can determine the sum value of each emergency outbound sub-score corresponding to the SKU to be out of the warehouse in the full-pallet picking mode as the emergency outbound score currently corresponding to the SKU to be out of the warehouse in the full-pallet picking mode, and determine the sum value of each emergency outbound sub-score corresponding to the SKU to be out of the warehouse in the piece-picking mode as the emergency outbound score currently corresponding to the SKU to be out of the warehouse in the piece-picking mode, that is, each SKU to be out of the warehouse on the target floor corresponds to two emergency outbound scores, one is the emergency outbound score in the full-pallet picking mode and the other is the emergency outbound score in the piece-picking mode.

[0076] Further, for each SKU to be out of the warehouse on the target floor, after the electronic device determines the emergency outbound score currently corresponding to the SKU to be out of the warehouse based on each emergency outbound sub-score corresponding to the SKU to be out of the warehouse, it can determine the SKU to be out of the warehouse currently corresponding to the target floor based on the emergency outbound scores currently corresponding to each SKU to be out of the warehouse on the target floor.

[0077] In one embodiment, the emergency outbound score includes the emergency outbound score in the full-pallet picking mode; in this case, based on the emergency outbound scores currently corresponding to each SKU to be out of the warehouse on the target floor in the full-pallet picking mode, the electronic device can select the SKU to be out of the warehouse with the emergency outbound score in the full-pallet picking mode not lower than the score threshold from each SKU to be out of the warehouse on the target floor as the SKU to be out of the warehouse currently corresponding to the target floor, or can select the SKU to be out of the warehouse with the highest emergency outbound score in the full-pallet picking mode from each SKU to be out of the warehouse on the target floor as the SKU to be out of the warehouse currently corresponding to the target floor.

[0078] In another embodiment, the emergency outbound score includes the emergency outbound score in the piece-picking mode; in this case, based on the emergency outbound scores currently corresponding to each SKU to be out of the warehouse on the target floor in the piece-picking mode, the electronic device can select the SKU to be out of the warehouse with the emergency outbound score in the piece-picking mode not lower than the score threshold from each SKU to be out of the warehouse on the target floor as the SKU to be out of the warehouse currently corresponding to the target floor, or can select the SKU to be out of the warehouse with the highest emergency outbound score in the piece-picking mode from each SKU to be out of the warehouse on the target floor as the SKU to be out of the warehouse currently corresponding to the target floor.

[0079] In another embodiment, the emergency outbound score includes the emergency outbound score in the full-pallet picking mode and the emergency outbound score in the piece-picking mode; in this case, based on the emergency outbound score in the full-pallet picking mode, the emergency outbound score in the piece-picking mode, and the current emergency outbound score corresponding to each to-be-outbound SKU on the target floor in the piece-picking mode, the electronic device can select, from each to-be-outbound SKU on the target floor, the to-be-outbound SKU whose emergency outbound score is not lower than the score threshold as the emergency outbound SKU currently corresponding to the target floor, or select the to-be-outbound SKU with the highest emergency outbound score from each to-be-outbound SKU on the target floor as the emergency outbound SKU currently corresponding to the target floor.

[0080] Further, after the electronic device determines the emergency outbound SKU currently corresponding to the target floor, it can allocate an idle transport vehicle to the emergency outbound SKU currently corresponding to the target floor based on the information of the idle transport vehicles currently corresponding to the target floor. The specific allocation method is the same as the specific allocation method in step 204 above, and the repeated parts will not be elaborated.

[0081] In addition, in the embodiment of the present application, after the electronic device allocates an idle transport vehicle to the emergency outbound SKU currently corresponding to the target floor based on the information of the idle transport vehicles currently corresponding to the target floor, it can also determine the outbound picking mode currently corresponding to the emergency outbound SKU as the target outbound picking mode, and use the idle transport vehicle allocated to the emergency outbound SKU to perform outbound picking on the emergency outbound SKU based on the target outbound picking mode.

[0082] In practical applications, before the electronic device allocates idle transport vehicles according to the transport vehicle allocation method in the transport capacity allocation layer of the warehouse control system, the overall planning method in the overall planning layer of the warehouse control system has already located each to-be-outbound SKU on the target floor and the candidate outbound pallets of each to-be-outbound SKU based on parameters such as the total number of outbound pallets and the number of blocked pallets in the target warehouse. Based on this, after the electronic device allocates an idle transport vehicle to the emergency outbound SKU currently corresponding to the target floor based on the information of the idle transport vehicles currently corresponding to the target floor, it can also select a target pallet for outbound picking of the emergency outbound SKU from the candidate outbound pallets of the emergency outbound SKU. Specifically, the electronic device can adopt, but is not limited to, the following methods:

[0083] First, for each non-outbound pallet among the candidate outbound pallets currently corresponding to the emergency outbound SKU, that is, for each to-be-outbound pallet currently corresponding to the emergency outbound SKU, the electronic device determines the no-load cost of the to-be-outbound pallet based on the time consumed by the idle transport vehicle allocated to the emergency outbound SKU to reach the location of the to-be-outbound pallet without load.

[0084] Specifically, for each unshipped pallet among the candidate outbound pallets currently corresponding to the emergency outbound SKU of the electronic device, based on the time consumed by the idle transport vehicle assigned to the emergency outbound SKU to reach the location of the to-be-outbound pallet empty, the electronic device can use a time cost calculation function to obtain the empty-load cost of the to-be-outbound pallet. For example, for each unshipped pallet among the candidate outbound pallets currently corresponding to the emergency outbound SKU of the electronic device, the electronic device can use the following formula (3) to obtain the empty-load cost of the to-be-outbound pallet;

[0085] cost tp =f(t tp ) …… Formula (3)

[0086] Where cost tp represents the empty-load cost of the to-be-outbound pallet, f represents the time cost calculation function, and t tp represents the time consumed by the idle transport vehicle assigned to the emergency outbound SKU to reach the location of the to-be-outbound pallet empty.

[0087] Then, based on the empty-load costs of the to-be-outbound pallets currently corresponding to the emergency outbound SKU, the electronic device selects the to-be-outbound pallet with the minimum empty-load cost as the target pallet from the to-be-outbound pallets currently corresponding to the emergency outbound SKU.

[0088] Finally, the electronic device uses the idle transport vehicle assigned to the emergency outbound SKU and the target pallet to perform the outbound operation of the emergency outbound SKU. Of course, after determining the outbound picking method currently corresponding to the emergency outbound SKU as the target outbound picking method, the electronic device can use the idle transport vehicle assigned to the emergency outbound SKU and the target pallet, and combine the target outbound picking method to perform outbound picking on the emergency outbound SKU.

[0089] Next, taking "allocating idle four-way shuttles on the target floor in a four-way shuttle warehouse based on the emergency outbound of each to-be-outbound SKU currently corresponding to the target floor in the four-way shuttle warehouse" as a specific application scenario, the method for allocating transport vehicles provided in the embodiments of the present application will be further described in detail. Refer to Figure 2 As shown, the specific process of the method for allocating transport vehicles provided in the embodiments of the present application is as follows:

[0090] Step 201: The electronic device determines the information of the idle four-way shuttles currently corresponding to the target floor in the four-way shuttle warehouse; where the target floor can be each floor in the four-way shuttle warehouse or a specified floor in the four-way shuttle warehouse.

[0091] Step 202: The electronic device determines the to-be-outbound SKU subsequence currently corresponding to each outbound vehicle based on the sequence of to-be-outbound SKUs in the whole warehouse.

[0092] Step 203: For each SKU to be shipped out on the target floor, after the electronic device determines the corresponding target outbound vehicles for the SKU to be shipped out, based on the arrangement position information of the SKU to be shipped out in the subsequences of SKUs to be shipped out corresponding to the respective target outbound vehicles, the electronic device determines the emergency outbound sub-scores of the SKU to be shipped out corresponding to the respective target outbound vehicles in the full-pallet picking mode and the emergency outbound sub-scores of the SKU to be shipped out corresponding to the respective target outbound vehicles in the piece-picking mode.

[0093] In specific implementation, for each target outbound vehicle, the electronic device can determine the emergency outbound sub-score of the SKU to be shipped out corresponding to the target outbound vehicle in the full-pallet picking mode based on the total number of pallets required for all SKUs to be shipped out before the SKU to be shipped out in the subsequence of SKUs to be shipped out currently corresponding to the target outbound vehicle, the number of pallets required for the SKU to be shipped out, the constant parameter of the full-pallet picking mode, and the current capacity of the pallet line; and determine the emergency outbound sub-score of the SKU to be shipped out corresponding to the target outbound vehicle in the piece-picking mode based on the total number of cases of all SKUs to be shipped out before the SKU to be shipped out in the subsequence of SKUs to be shipped out currently corresponding to the target outbound vehicle, the number of cases of the SKU to be shipped out, the constant parameter of the piece-picking mode, and the current capacity of the case line.

[0094] Step 204: For each SKU to be shipped out on the target floor, the electronic device determines the sum of the emergency outbound sub-scores of the SKU to be shipped out corresponding to the SKU to be shipped out in the full-pallet picking mode as the current emergency outbound score of the SKU to be shipped out in the full-pallet picking mode, and determines the sum of the emergency outbound sub-scores of the SKU to be shipped out corresponding to the SKU to be shipped out in the piece-picking mode as the current emergency outbound score of the SKU to be shipped out in the piece-picking mode.

[0095] Step 205: Based on the current emergency outbound scores of the SKUs to be shipped out on the target floor in the full-pallet picking mode and the current emergency outbound scores of the SKUs to be shipped out on the target floor in the piece-picking mode, the electronic device selects the SKU to be shipped out with the highest emergency outbound score as the current emergency outbound SKU corresponding to the target floor.

[0096] In specific implementation, the electronic device can select, from the SKUs to be shipped out on the target floor, the SKU with the highest emergency shipment score in the full-pallet picking mode as the emergency shipment SKU corresponding to the current target floor in the full-pallet picking mode based on the current emergency shipment scores of the SKUs to be shipped out on the target floor in the full-pallet picking mode, and select, from the SKUs to be shipped out on the target floor, the SKU with the highest emergency shipment score in the piece-picking mode as the emergency shipment SKU corresponding to the current target floor in the piece-picking mode based on the current emergency shipment scores of the SKUs to be shipped out on the target floor in the piece-picking mode. Then, from the emergency shipment SKU corresponding to the current target floor in the full-pallet picking mode and the emergency shipment SKU corresponding to the current target floor in the piece-picking mode, the electronic device selects the SKU with the highest emergency shipment score as the emergency shipment SKU corresponding to the current target floor.

[0097] Step 206: The electronic device allocates an idle four-way shuttle vehicle for the emergency shipment SKU corresponding to the current target floor based on the information of the idle four-way shuttle vehicles corresponding to the current target floor.

[0098] Step 207: For each pallet to be shipped out corresponding to the emergency shipment SKU, the electronic device determines the no-load cost of the pallet to be shipped out based on the time consumed for the idle transport vehicle allocated for the emergency shipment SKU to reach the location where the pallet to be shipped out is located without load.

[0099] Step 208: The electronic device selects, from the pallets to be shipped out corresponding to the emergency shipment SKU, the pallet to be shipped out with the minimum no-load cost as the target pallet based on the no-load costs of the pallets to be shipped out corresponding to the emergency shipment SKU.

[0100] Step 209: The electronic device determines the outbound picking mode corresponding to the emergency shipment SKU as the target outbound picking mode.

[0101] Step 210: The electronic device uses the idle transport vehicle and the target pallet allocated for the emergency shipment SKU, and in combination with the target outbound picking mode, performs the outbound operation of the emergency shipment SKU.
