[0029] like Figure 1 As shown, the system architecture 100 may include terminal devices 1011, 1012, 1013, a network 102, and a server 103. The network 102 is used to provide a medium for communication links between the terminal devices 1011, 1012, 1013 and the server 103. The network 102 may include various connection types, such as wired, wireless communication links, or optical fiber cables, etc.

[0030] The user can use the terminal devices 1011, 1012, 1013 to interact with the server 103 through the network 102 to send or receive messages, etc. For example, the terminal devices 1011, 1012, 1013 can receive order addition information sent by the server 103. Various communication client applications, such as order management applications, instant messaging software, etc., can be installed on the terminal devices 1011, 1012, 1013.

[0031] Terminal devices 1011, 1012, 1013 can be hardware or software. When terminal devices 1011, 1012, 1013 are hardware, they can be various electronic devices with speakers and supporting information interaction, including but not limited to smart phones, tablet computers, laptop portable computers, etc. When terminal devices 1011, 1012, 1013 are software, they can be installed in the electronic devices listed above. It can be implemented as multiple software or software modules (for example, multiple software or software modules for providing distributed services), or it can be implemented as a single software or software module. No specific limitation is made here.

[0032] The server 103 may be a server that provides various services. For example, it may be a server that processes the order to be added and at least one order set currently processed by at least one workstation. The server 103 may first obtain the order information of the order to be added and the preset order information set; then, based on the order information of the order to be added and the order information set, a target order set may be selected from the at least one order set; then, based on the order information of the order to be added and the order information of the target order set, a target workstation may be determined from the at least one workstation; finally, the order addition information may be sent to the terminal devices 1011, 1012, 1013 corresponding to the target workstation.

[0033] It should be noted that the server 103 can be hardware or software. When the server 103 is hardware, it can be implemented as a distributed server cluster consisting of multiple servers, or it can be implemented as a single server. When the server 103 is software, it can be implemented as multiple software or software modules (for example, for providing distributed services), or it can be implemented as a single software or software module. No specific limitation is made here.

[0034] It should be noted that the method for processing orders provided in the embodiment of the present application is usually executed by the server 103.

[0035] It should be understood that Figure 1 The number of terminal devices, networks and servers in the embodiment is only for illustration. Any number of terminal devices, networks and servers may be provided according to implementation requirements.

[0036] Continue to refer Figure 2 , shows a process 200 of an embodiment of a method for processing an order according to the present application. The method for processing an order comprises the following steps:

[0037] Step 201, obtaining order information of the order to be added and a preset order information set.

[0038] In this embodiment, the execution entity (eg Figure 1 The server shown in the figure can obtain the order information of the order to be added and the preset order information set. The above-mentioned order to be added can be an order to be added to the existing order set. The above-mentioned order information set may include the order information of at least one order set currently processed by at least one workstation. In the logistics management system of the warehouse, the goods picker needs to pick the items indicated by the order at the workstation. There are usually multiple workstations in the warehouse. The at least one order set currently processed by the above-mentioned at least one workstation may include the order set corresponding to the items that have been picked, are being picked, and have not been picked, and the corresponding order information has been sent to the terminal device of the workstation. Here, the order information may include but is not limited to at least one of the following: order number, item identification of the item indicated by the order (for example, SKU (Stock Keeping Unit)) and the current status of the order. The item indicated by the order refers to the item purchased by the user through the order operation.

[0039] Step 202: Based on the order information and order information set of the order to be added, a target order set is selected from at least one order set.

[0040] In this embodiment, based on the order information of the order to be added and the order information set obtained in step 201, the execution subject can select a target order set from at least one order set currently processed by at least one workstation. The order information can include the current state of the order, and the current state of the order can include that the item indicated by the order is in a transport state, and the item in a transport state can be understood as the shelf where the item is located is in a transport state. At this time, the execution subject can select an order set whose current state is that the shelf where the item indicated by the order is located is in a transport state from the at least one order set as the target order set.

[0041] Step 203: Determine a target workstation from at least one workstation based on the order information of the order to be added and the order information of the target order set.

[0042] In this embodiment, the execution subject may determine the target workstation from the at least one workstation based on the order information of the order to be added acquired in step 201 and the order information of the target order set selected in step 202. Here, the execution subject may select the workstation that processes the target order set from the at least one workstation as the target workstation.

[0043] Step 204: Send order additional information to the terminal device corresponding to the target workstation.

[0044] In this embodiment, the execution subject may send order additional information to the terminal device corresponding to the target workstation. Here, the order additional information may include order information of the order to be added, for example, the item ID (SKU) of the item indicated by the order, and the quantity of items corresponding to each item ID. The order additional information may also include the order set ID of the target order set.

[0045] Here, after selecting the target order set, the execution subject may add the order information of the order to be added to the order information set of the target order set. At this time, the order additional information may include the added order information set.

[0046] In some optional implementations of this embodiment, the execution subject may select a target order set from the at least one order set based on the order information of the order to be added and the order information set in the following manner: the execution subject may first select a candidate order set from the at least one order set based on the order information of the order to be added and the order information set. The order information may include the current state of the order, and the current state of the order may include that the item indicated by the order is in a transport state, and the item in a transport state may be understood as the shelf where the item is located is in a transport state. At this time, the execution subject may select an order set whose current state is that the shelf where the item indicated by the order is located is in a transport state from the at least one order set as the candidate order set. Afterwards, the execution subject may determine whether the number of the candidate order sets is equal to a preset value. Here, the preset value is usually 1, that is, it is determined whether the number of the candidate order sets is equal to 1. If it is determined that the number of the candidate order sets is equal to the preset value, the execution subject may determine the candidate order set as the target order set.

[0047] In some optional implementations of the present embodiment, the execution subject may select a target order set from the at least one order set based on the order information of the order to be added and the order information set in the following manner: the execution subject may first select a candidate order set from the at least one order set based on the order information of the order to be added and the order information set. The order information may include the current status of the order, and the current status of the order may include that the item indicated by the order is in a transport state, and the item in a transport state may be understood as the shelf where the item is located is in a transport state. At this time, the execution subject may select an order set whose current status is that the shelf where the item indicated by the order is located is in a transport state from the at least one order set as the candidate order set.

[0048] Afterwards, the execution subject may determine whether the number of the candidate order set is greater than a preset value. Here, the preset value is usually 1, that is, determine whether the number of the candidate order set is greater than 1.

[0049] Here, if it is determined that the number of the candidate order sets is greater than the preset value, the execution subject may determine the degree of match between the order to be added and each candidate order set in at least two candidate order sets. Specifically, the execution subject may match the item identifiers of the items indicated by the order to be added with the item identifiers of the items indicated by each candidate order set in at least two candidate order sets one by one, and determine the ratio of the number of matched item identifiers to the number of item identifiers of the items indicated by the order to be added as the degree of match. As an example, if the number of item identifiers of the items indicated by the order to be added is 4, and the number of item identifiers of the items indicated by the order to be added and the item identifiers of the items indicated by the first candidate order set is 1, the corresponding degree of match is 0.25; if the number of item identifiers of the items indicated by the order to be added and the item identifiers of the items indicated by the third candidate order set is 4, the corresponding degree of match is 1.

[0050] After determining the matching degree, the execution subject may select a target order set from the candidate order set based on the matching degree. Specifically, the execution subject may select the candidate order set with the highest matching degree from the candidate order set as the target order set. The execution subject may also select any candidate order set with a matching degree greater than a preset matching degree threshold from the candidate order set as the target order set.

[0051] In some optional implementations of this embodiment, the order information may include at least one of the following: a preset order type, the latest delivery time of the items indicated by the order, and the number of items indicated by the order. The above order type may be set based on timeliness, business type, the number of items indicated by the order, etc. As an example, the above order types may include: "precision delivery" orders (orders delivered to customer points within a preset period (e.g., 2 hours) after the user places an order), "group purchase" orders, and "flash sale" orders. The latest delivery time of the items indicated by the order may be the latest time when the items leave the warehouse. Here, the number of items may refer to the weight, volume, number of pieces, number of products, etc. of the items. Among them, the number of pieces refers to the number of items, and the number of products refers to the number of categories of items. As an example, if the items indicated by the order are 1 item A and 2 items B, the number of pieces of the items is 3 and the number of products is 2.

[0052] In some optional implementations of this embodiment, the execution subject may select a target order set from the at least one order set based on the order information of the order to be added and the order information set in the following manner: the execution subject may select an order set that satisfies a preset condition from the at least one order set as the target order set. Here, the preset condition may include at least one of the following: the order type of the order set is the same as the order type of the order to be added; the latest delivery time of the items indicated by the order set is not earlier than the latest delivery time of the items indicated by the order to be added; the sum of the number of items indicated by the order set and the number of items indicated by the order to be added is less than a preset item quantity threshold. The number of items indicated by the order set is usually the sum of the number of items indicated by each order included in the order set. It should be noted that since the number of items may refer to the weight, volume, number of pieces, number of items, etc. of the items, the corresponding item quantity threshold may be an item weight threshold, an item volume threshold, an item piece threshold, and an item number threshold. As an example, if the order type of the above-mentioned order to be added is a "group purchase" order, the above-mentioned execution entity can select an order set whose order type is a "group purchase" order from the above-mentioned at least one order set. If the latest delivery time of the items indicated by the above-mentioned order to be added is 8 o'clock, the above-mentioned execution entity can select an order set whose latest delivery time of the indicated items is not earlier than 8 o'clock from the above-mentioned at least one order set. If the weight of the items indicated by the above-mentioned order to be added is 8 kilograms, the volume is 0.5 square meters, the number of pieces is 3 pieces, and the number of items is 2 pieces, the item weight threshold is 100 kilograms, the item volume threshold is 5 square meters, the item number threshold is 50 pieces, and the item number threshold is 30 pieces, then the above-mentioned execution entity can select an order set from the above-mentioned at least one order set whose weight of the items indicated by the order set is less than 92 kilograms, the volume is less than 4.5 square meters, the number of pieces is less than 47 pieces, and the number of items is less than 28 pieces.

[0053] Continue to see Figure 3 , Figure 3 FIG. 1 is a schematic diagram of an application scenario of the method for processing an order according to this embodiment. Figure 3In the application scenario, the server 301 may first obtain the order information 302 of the order to be added and the preset order information set 303. Here, the order information may include the SKU of the item indicated by the order and the current state of the order. The order information set 303 includes the order information of each of the fifty order sets currently processed by workstation A, workstation B and workstation C. Afterwards, the server 301 may select a target order set 305 from the fifty order sets 304 currently processed by workstation A, workstation B and workstation C based on the order information 302 of the order to be added and the order information set 303. The server 301 may select an order set whose current state is that the shelf where the item indicated by the order is located is in the transport state from the fifty order sets 304 as the target order set 305. Here, the target order set 305 is order set 21. Then, the server 301 may determine the target workstation 307 from workstation A, workstation B and workstation C based on the order information 302 of the order to be added and the order information 306 of the target order set. Here, the workstation B processing the order set 21 is determined as the target workstation 307. The server 301 can send order additional information 309 to the terminal device 308 corresponding to the workstation B. Here, the order additional information includes order information 302 of the order to be added.

[0054] The method provided by the above-mentioned embodiment of the present application adds orders in the order pool that have a high degree of matching with the collection order being picked to the collection order being picked, so that the additional orders and the orders being picked are picked together, thereby improving the picking efficiency and reducing the number of vehicle transportation times.

[0055] Further references Figure 4 , Figure 4 This is a process 400 of determining a target workstation in a method for processing an order according to the present application. Figure 4 As shown, in this embodiment, the step of determining the target workstation includes:

[0056] Step 401: determine the workstation currently processing the target order set as a candidate workstation.

[0057] In this embodiment, the order information may include the quantity of items indicated by the order. In the logistics management system of the warehouse, the staff needs to pick the items indicated by the order at the workstation. There are usually multiple workstations in the warehouse. At least one slot can be set in the workstation. Generally speaking, the workstation can be provided with a distribution wall (distribution wall), and at least one slot can be set on the distribution wall. The distribution wall is a device based on the sorting system that processes orders in a short time. After the staff picks out the items in the storage area according to the order wave, they go to the distribution area to scan the product barcode, and then put the products of the same order into the same slot (grid) according to the label light indication.

[0058] In this embodiment, the execution entity for processing the order may determine the workstation currently processing the above target order set as a candidate workstation.

[0059] Step 402: determine whether the sum of the item quantity of the items indicated by the to-be-added order and the item quantity of the items indicated by the target order set is less than or equal to a preset item quantity threshold.

[0060] In this embodiment, the execution entity may determine whether the sum of the number of items indicated by the order to be added and the number of items indicated by the target order set is less than or equal to a preset item quantity threshold. The item quantity may refer to the weight, volume, number of pieces, number of products, etc. of the items. The number of pieces refers to the number of items, and the number of products refers to the number of categories of items. As an example, if the items indicated by the order are 1 item A and 2 items B, the number of items is 3 and the number of products is 2. It should be noted that since the number of items may refer to the weight, volume, number of pieces, number of products, etc. of the items, the corresponding item quantity threshold may be an item weight threshold, an item volume threshold, an item piece threshold, and an item product threshold.

[0061] Here, if the quantity of items refers to the weight, volume, number of pieces and number of items, the execution subject may respectively determine whether the sum of the weight of the items indicated by the order to be added and the weight of the items indicated by the target order set is less than or equal to the preset weight threshold of the items, determine whether the sum of the volume of the items indicated by the order to be added and the volume of the items indicated by the target order set is less than or equal to the preset volume threshold of the items, determine whether the sum of the number of items of the items indicated by the order to be added and the number of items of the items indicated by the target order set is less than or equal to the preset number threshold of the items, and determine whether the sum of the number of items of the items indicated by the order to be added and the number of items of the items indicated by the target order set is less than or equal to the preset number threshold of the items. If it is determined that the sum of the weight of the items, the sum of the volume of the items, the sum of the number of the items and the sum of the number of the items are all less than or equal to the corresponding sum of the weight of the items, the sum of the volume of the items, the sum of the number of the items and the sum of the number of the items, the execution subject may execute step 403. If it is determined that at least one of the sum of the item weights, the sum of the item volumes, the sum of the number of items, and the sum of the number of items is greater than the corresponding sum of the item weights, the sum of the item volumes, the sum of the number of items, and the sum of the number of items, the above-mentioned execution entity can execute step 404.

[0062] Step 403 : in response to determining that the sum of the item quantity of the items indicated by the to-be-added order and the item quantity of the items indicated by the target order set is less than or equal to the item quantity threshold, determining the candidate workstation as the target workstation.

[0063] In this embodiment, if it is determined in step 402 that the sum of the number of items indicated by the above-mentioned additional order and the number of items indicated by the above-mentioned target order set is less than or equal to the above-mentioned item quantity threshold, the above-mentioned execution entity can determine the candidate workstation determined in step 401 as the target workstation.

[0064] In some optional implementations of this embodiment, the execution subject may use the slot corresponding to the target order set as the target slot. When allocating the order set to the workstation, the execution subject may associate the order information with the slot identifier of the slot where the item indicated by the order set is to be placed and send it to the terminal device of the workstation. At this time, the slot associated with the order information of the target order set may be used as the target slot.

[0065] Step 404, in response to determining that the sum of the item quantity of the items indicated by the order to be added and the item quantity of the items indicated by the target order set is greater than the item quantity threshold, determine whether the slot quantity of the slot currently set at the candidate workstation is equal to the preset slot quantity threshold.

[0066] In this embodiment, if it is determined in step 402 that the sum of the number of items indicated by the order to be added and the number of items indicated by the target order set is greater than the item number threshold, the execution subject may determine whether the number of slots currently set in the candidate workstation is equal to a preset slot number threshold (e.g., 12, 20, etc.). The execution subject may obtain the number of slots currently set in the candidate workstation. If it is determined that the number of slots currently set in the candidate workstation is not equal to the preset slot number threshold, that is, the number of slots does not reach the upper limit of the number of slots, the execution subject may execute step 405. If it is determined that the number of slots currently set in the candidate workstation is equal to the preset slot number threshold, that is, the number of slots reaches the upper limit of the number of slots, the execution subject may execute step 406.

[0067] Step 405: In response to determining that the number of slots currently set in the candidate workstation is not equal to the slot number threshold, the candidate workstation is determined as a target workstation.

[0068] In this embodiment, if it is determined in step 404 that the number of slots currently set for the candidate workstation is not equal to the preset slot number threshold, that is, the number of slots does not reach the slot number upper limit, the execution entity can determine the candidate workstation determined in step 401 as the target workstation.

[0069] In some optional implementations of this embodiment, after the candidate workstation is determined as the target workstation, the execution entity may add a slot identifier for the target workstation, and may determine the slot indicated by the added slot identifier as the target slot. The slot identifier may be determined based on the number of slots currently set for the workstation. For example, if the number of slots currently set for the target workstation is 9, the newly added slot identifier may be 10. After adding the slot identifier for the target workstation, the execution entity may send slot addition information for adding the slot to the terminal device of the target workstation, and the slot addition information may include the slot identifier. After the staff in the workstation views the slot addition information including the slot identifier through the terminal device, a slot may be added to the distribution wall, and the added slot may be used as the target slot.

[0070] Step 406: In response to determining that the number of slots currently set at the candidate workstation is equal to the slot number threshold, select a workstation whose number of slots currently set is less than the slot number threshold from at least one workstation as a target workstation.

[0071] In this embodiment, if it is determined in step 404 that the number of slots currently set in the candidate workstation is equal to the preset slot number threshold, that is, the number of slots reaches the slot number upper limit, the execution subject may select a workstation whose number of slots currently set is less than the slot number threshold from the at least one workstation as the target workstation. If there are multiple workstations whose number of slots currently set is less than the slot number threshold, the execution subject may select any workstation as the target workstation, or may select the workstation whose number of slots currently set is the smallest as the target workstation. The execution subject may obtain in advance the number of slots currently set in each of the at least one workstation.

[0072] Here, since the determined target workstation is not the workstation currently processing the above-mentioned target order set, when the target shelf (the shelf on which the items indicated by the above-mentioned target order set are placed) arrives at the workstation currently processing the above-mentioned target order set, after the staff completes the picking work for the target shelf, it is usually necessary to transport the above-mentioned target shelf to the above-mentioned target workstation so that the staff at the target workstation can complete the picking work for the items indicated by the order to be added.

[0073] In some optional implementations of this embodiment, after selecting a workstation whose number of currently set slots is less than the slot number threshold from the at least one workstation as the target workstation, the execution entity may add a slot identifier for the target workstation, and may determine the slot indicated by the added slot identifier as the target slot. After adding the slot identifier for the target workstation, the execution entity may send slot addition information for adding the slot to the terminal device of the target workstation, and the slot addition information may include the slot identifier. After the staff in the workstation views the slot addition information including the slot identifier through the terminal device, a slot may be added to the distribution wall, and the added slot may be used as the target slot.

[0074] In some optional implementations of this embodiment, the order addition information may include the slot identifier of the target slot. After checking the slot identifier of the target slot, the staff of the workstation may place the items indicated by the order to be added on the target slot to realize order distribution.

[0075] The method provided by the above embodiment of the present application can select a target workstation for processing the additional order by comparing the sum of the item quantities of the items indicated by the order to be added and the items indicated by the above target order set with a preset item quantity threshold, and comparing the slot quantity of the slot currently set by the workstation with the preset slot quantity threshold. In this way, the additional order can be reasonably allocated to improve the workstation's order picking efficiency.

[0076] Further references Figure 5 As an implementation of the methods shown in the above figures, the present application provides an embodiment of a device for processing an order. Figure 2 Corresponding to the method embodiment shown, the device can be specifically applied to various electronic devices.

[0077] like Figure 5 As shown, the device 500 for processing an order in this embodiment includes: an acquisition unit 501, a selection unit 502, a determination unit 503 and a sending unit 504. The acquisition unit 501 is configured to acquire the order information of the order to be added and a preset order information set, wherein the order information set includes the order information of at least one order set currently processed by at least one workstation; the selection unit 502 is configured to select a target order set from at least one order set based on the order information of the order to be added and the order information set; the determination unit 503 is configured to determine a target workstation from at least one workstation based on the order information of the order to be added and the order information of the selected target order set; the sending unit 504 is configured to send order addition information to the terminal device corresponding to the target workstation, wherein the order addition information includes the order information of the order to be added.

[0078] In this embodiment, the specific processing of the acquisition unit 501, the selection unit 502, the determination unit 503 and the sending unit 504 of the device 500 for processing an order can be referred to. Figure 2 This corresponds to step 201, step 202, step 203 and step 204 in the embodiment.

[0079] In some optional implementations of this embodiment, the selection unit 502 may select a target order set from the at least one order set based on the order information of the order to be added and the order information set in the following manner: the selection unit 502 may first select a candidate order set from the at least one order set based on the order information of the order to be added and the order information set. The order information may include the current state of the order, and the current state of the order may include that the item indicated by the order is in a transport state. The item in the transport state may be understood as the shelf where the item is located is in a transport state. At this time, the selection unit 502 may select an order set whose current state is that the shelf where the item indicated by the order is located is in a transport state from the at least one order set as the candidate order set. Afterwards, the selection unit 502 may determine whether the number of the candidate order sets is equal to a preset value. Here, the preset value is usually 1, that is, it is determined whether the number of the candidate order sets is equal to 1. If it is determined that the number of the candidate order sets is equal to the preset value, the selection unit 502 may determine the candidate order set as the target order set.

[0080] In some optional implementations of the present embodiment, the selection unit 502 may select a target order set from the at least one order set based on the order information of the order to be added and the order information set in the following manner: The selection unit 502 may first select a candidate order set from the at least one order set based on the order information of the order to be added and the order information set. The order information may include the current status of the order, and the current status of the order may include that the item indicated by the order is in a transport state, and the item in a transport state may be understood as the shelf where the item is located is in a transport state. At this time, the selection unit 502 may select an order set whose current status is that the shelf where the item indicated by the order is located is in a transport state from the at least one order set as a candidate order set.

[0081] Afterwards, the selection unit 502 may determine whether the number of the candidate order sets is greater than a preset value. Here, the preset value is usually 1, that is, it is determined whether the number of the candidate order sets is greater than 1.

[0082] Here, if it is determined that the number of the candidate order sets is greater than the preset value, the selection unit 502 may determine the degree of match between the order to be added and each of the candidate order sets in the at least two candidate order sets. Specifically, the selection unit 502 may match the item identifiers of the items indicated by the order to be added with the item identifiers of the items indicated by each of the at least two candidate order sets, and determine the degree of match as the ratio of the number of matched item identifiers to the number of item identifiers of the items indicated by the order to be added. As an example, if the number of item identifiers of the items indicated by the order to be added is 4, and the number of item identifiers of the items indicated by the order to be added and the item identifiers of the items indicated by the first candidate order set is 1, the corresponding degree of match is 0.25; if the number of item identifiers of the items indicated by the order to be added and the item identifiers of the items indicated by the third candidate order set is 4, the corresponding degree of match is 1.

[0083] After determining the matching degree, the selection unit 502 may select a target order set from the candidate order set based on the matching degree. Specifically, the selection unit 502 may select a candidate order set with the highest matching degree from the candidate order set as the target order set. The selection unit 502 may also select any candidate order set with a matching degree greater than a preset matching degree threshold from the candidate order set as the target order set.

[0084] In some optional implementations of this embodiment, the order information may include at least one of the following: a preset order type, the latest delivery time of the items indicated by the order, and the number of items indicated by the order. The above order types may be set based on timeliness, business type, the number of items indicated by the order, and the like. As an example, the above order types may include: "precision delivery" orders, "group purchase" orders, and "flash sale" orders. The latest delivery time of the items indicated by the order may be the latest time the items leave the warehouse. Here, the number of items may refer to the weight, volume, number of pieces, number of products, and the like of the items. Among them, the number of pieces refers to the number of items, and the number of products refers to the number of categories of items. As an example, if the items indicated by the order are 1 item A and 2 items B, the number of pieces of the items is 3 and the number of products is 2.

[0085] In some optional implementations of this embodiment, the selection unit 502 may select a target order set from the at least one order set based on the order information of the order to be added and the order information set in the following manner: the selection unit 502 may select an order set that meets a preset condition from the at least one order set as the target order set. Here, the preset condition may include at least one of the following: the order type of the order set is the same as the order type of the order to be added; the latest delivery time of the items indicated by the order set is not earlier than the latest delivery time of the items indicated by the order to be added; the sum of the number of items indicated by the order set and the number of items indicated by the order to be added is less than a preset item quantity threshold. The number of items indicated by the order set is usually the sum of the number of items indicated by each order included in the order set. It should be noted that since the number of items may refer to the weight, volume, number of pieces, number of items, etc. of the items, the corresponding item quantity threshold may be an item weight threshold, an item volume threshold, an item piece threshold, and an item number threshold. As an example, if the order type of the above-mentioned order to be added is a "group purchase" order, the above-mentioned selection unit 502 can select an order set whose order type is a "group purchase" order from the above-mentioned at least one order set. If the latest delivery time of the items indicated by the above-mentioned order to be added is 8 o'clock, the above-mentioned selection unit 502 can select an order set whose latest delivery time of the indicated items is not earlier than 8 o'clock from the above-mentioned at least one order set. If the weight of the items indicated by the above-mentioned order to be added is 8 kilograms, the volume is 0.5 square meters, the number of pieces is 3 pieces, and the number of items is 2 pieces, the item weight threshold is 100 kilograms, the item volume threshold is 5 square meters, the item number threshold is 50 pieces, and the item number threshold is 30 pieces, then the above-mentioned selection unit 502 can select an order set from the above-mentioned at least one order set whose weight of the items indicated by the order set is less than 92 kilograms, the volume is less than 4.5 square meters, the number of pieces is less than 47 pieces, and the number of items is less than 28 pieces.

[0086] In some optional implementations of this embodiment, the order information may include the number of items indicated by the order. In the logistics management system of the warehouse, the staff needs to pick the items indicated by the order at the workstation. A plurality of workstations are usually provided in the warehouse. At least one slot may be provided in the workstation. The sending unit 504 may determine the target workstation from the at least one workstation based on the order information of the order to be added and the order information of the target order set in the following manner: the sending unit 504 may determine the workstation currently processing the target order set as a candidate workstation. Afterwards, the sending unit 504 may determine whether the sum of the number of items indicated by the order to be added and the number of items indicated by the target order set is less than or equal to a preset threshold value of the number of items. The number of items may refer to the weight, volume, number of pieces, number of products, etc. of the items. Among them, the number of pieces refers to the number of items, and the number of products refers to the number of categories of items. It should be noted that, since the number of items may refer to the weight, volume, number of pieces, number of products, etc. of the items, the corresponding item quantity threshold may be an item weight threshold, an item volume threshold, an item piece threshold, and an item product threshold. Then, if it is determined that the sum of the item quantity of the items indicated by the above-mentioned to-be-added order and the item quantity of the items indicated by the above-mentioned target order set is less than or equal to the above-mentioned item quantity threshold, the above-mentioned sending unit 504 may determine the determined candidate workstation as the target workstation.

[0087] In some optional implementations of this embodiment, the sending unit 504 may use the slot corresponding to the target order set as the target slot. When allocating an order set to a workstation, the sending unit 504 may associate the order information with the slot identifier of the slot where the item indicated by the order set is to be placed and send it to the terminal device of the workstation. At this time, the slot associated with the order information of the target order set may be used as the target slot.

[0088] In some optional implementations of this embodiment, after determining whether the sum of the number of items indicated by the order to be added and the number of items indicated by the target order set is less than or equal to a preset item quantity threshold, if it is determined that the sum of the number of items indicated by the order to be added and the number of items indicated by the target order set is greater than the item quantity threshold, the sending unit 504 may determine whether the number of slots currently set in the candidate workstation is equal to the preset slot quantity threshold. The sending unit 504 may obtain the number of slots currently set in the candidate workstation. If it is determined that the number of slots currently set in the candidate workstation is not equal to the preset slot quantity threshold, that is, the number of slots does not reach the slot quantity upper limit, the sending unit 504 may determine the determined candidate workstation as the target workstation.

[0089] In some optional implementations of this embodiment, after the candidate workstation is determined as the target workstation, the sending unit 504 may add a slot identifier for the target workstation, and may determine the slot indicated by the added slot identifier as the target slot. The slot identifier may be determined based on the number of slots currently set for the workstation. For example, if the number of slots currently set for the target workstation is 9, the newly added slot identifier may be 10. After adding the slot identifier for the target workstation, the sending unit 504 may send slot addition information for adding the slot to the terminal device of the target workstation, and the slot addition information may include the slot identifier. After the staff in the workstation views the slot addition information including the slot identifier through the terminal device, a slot may be added to the distribution wall, and the added slot may be used as the target slot.

[0090] In some optional implementations of this embodiment, if it is determined that the number of slots currently set in the candidate workstation is equal to the preset slot number threshold, that is, the number of slots reaches the slot number upper limit, the sending unit 504 can select a workstation whose number of slots currently set is less than the slot number threshold from the at least one workstation as the target workstation. If there are multiple workstations whose number of slots currently set is less than the slot number threshold, the sending unit 504 can select any workstation as the target workstation, or select the workstation whose number of slots currently set is the smallest as the target workstation. The sending unit 504 can pre-acquire the number of slots currently set in each of the at least one workstation.

[0091] In some optional implementations of this embodiment, after selecting a workstation whose number of currently set slots is less than the slot number threshold from the at least one workstation as the target workstation, the sending unit 504 may add a slot identifier for the target workstation, and may determine the slot indicated by the added slot identifier as the target slot. After adding the slot identifier for the target workstation, the sending unit 504 may send slot addition information for adding a slot to the terminal device of the target workstation, and the slot addition information may include the slot identifier. After the staff in the workstation views the slot addition information including the slot identifier through the terminal device, a slot may be added to the distribution wall, and the added slot may be used as the target slot.

[0092] In some optional implementations of this embodiment, the order addition information may include the slot identifier of the target slot. After checking the slot identifier of the target slot, the staff of the workstation may place the items indicated by the order to be added on the target slot to realize order distribution.
