Description

BACKGROUND

Technical Field

This disclosure relates to an electronic apparatus for inventory management and an operation method thereof.

Description of the Related Art

Systems for storing and managing items to be shipped to customers upon placement of an order are of increasing importance in today's economic growth. New products are developed continuously, and many products are released on the market in real time. While this growth provides consumers with more choices of goods and services, many companies involved in such businesses (e.g., retail stores, wholesale stores, etc.) have difficulties in storing and managing rapidly increasing items.
In order to utilize space efficiently, in a physical location (for example, a fulfillment center) where items are stored, a task called consolidation is required to move items already on display from a location to another location. The consolidation task may be performed to compress two or more locations having items with low space usage rates into one location, move an item with a high order rate to a place to be picked easily, or move an item with a low order rate to a separate place. A typical consolidation task may be performed using a stock transfer tool in a non-trackable state according to a manual. Thus, an automation of the consolidation task may be required.

Specific details of example embodiments are included in the detailed description and drawings.

Effects

According to example embodiments, when setting a target value of an item space usage rate in units of a zone instead of manually performing a consolidation task using an inventory transport tool, a corresponding location may be automatically allocated in a system and thus, the consolidation task may be performed based on real-time data rather than a subjective decision made by an operator. For example, in a case of a task for compressing items in two or more locations into one location, instead of performing a consolidation task by visually checking, the location compressing task may be performed based on an item space usage rate for each zone calculated in real time. Through this, it is possible to reflect an inventory status changing in real time and increase a user's convenience.
Further, since the operator's subjective decision is not involved, items may be uniformly picked and displayed based on a record in a server. For example, instead of subjectively determining a degree of an emptiness of a space by visually checking a task location, an item space usage rate may be automatically calculated based on a location registered on a system and an SKU ID of an item stored in the location, thereby allocating a location in which a picking task is to be performed. Also, the location may be allocated such that an item with a high order rate is moved to a place where it is easy to pick or an item with a low order rate is moved to a separate place, which may enable item tracking.
Effects are not limited to the aforementioned effects, and other effects not mentioned will be clearly understood by those skilled in the art from the description of the claims.

DETAILED DESCRIPTION

Terms used in the embodiments are selected, as much as possible, from general terms that are widely used at present while taking into consideration the functions obtained in accordance with the present disclosure, but these terms may be replaced by other terms based on intentions of those skilled in the art, customs, emergence of new technologies, or the like. Also, in a particular case, terms that are arbitrarily selected by the applicant of the present disclosure may be used. In this case, the meanings of these terms may be described in corresponding description parts of the disclosure. Accordingly, it should be noted that the terms used herein should be construed based on practical meanings thereof and the whole content of this specification, rather than being simply construed based on names of the terms.
In the entire specification, when an element is referred to as “including” another element, the element should not be understood as excluding other elements so long as there is no special conflicting description, and the element may include at least one other element. In addition, the terms “unit” and “module”, for example, may refer to a component that exerts at least one function or operation, and may be realized in hardware or software, or may be realized by combination of hardware and software.
The expression “at least one of A, B, and C” may include the following meanings: A alone; B alone; C alone; both A and B together; both A and C together; both B and C together; and all three of A, B, and C together.
In the present disclosure, a “terminal” may be implemented as a computer or a portable terminal capable of accessing a server or another terminal through a network. Here, the computer may include, for example, a laptop computer, a desktop computer, and a notebook equipped with a web browser. The portable terminal may be a wireless communication device ensuring a portability and a mobility, and include any type of handheld wireless communication device, for example, a tablet PC, a smartphone, a communication-based terminal such as international mobile telecommunication (IMT), code division multiple access (CDMA), W-code division multiple access (W-CDMA), and long term evolution (LTE).
In the following description, embodiments of the present disclosure will be described in detail with reference to the drawings so that those skilled in the art can easily carry out the present disclosure. The present disclosure may be embodied in many different forms and is not limited to the embodiments described herein. In the present disclosure, an item may indicate a single item, or may indicate a set of items of the same type. Also, an item may indicate a predetermined quantity of items corresponding to the same stock keeping unit (SKU). For example, an item having a specific SKU identification (ID) may indicate a predetermined quantity of items. Hereinafter, example embodiments of the present disclosure will be described with reference to the drawings.
FIG. 1 illustrates an operation system for inventory management according to an example embodiment.
An operation system for inventory management according to an example embodiment may refer to a system used for a consolidation process but is not limited thereto. As described above, the consolidation may be a task of moving inventory items already on display from a location to another location for efficient space utilization. Here, the location may belong to a zone in which an item is stored, and may be the zone and a physical location such as an aisle, a bay, a shelf, and the like included in the zone. The consolidation may be to compress items arranged in two or more locations with low space usage rates into one location. Here, the item space usage rate may be a ratio of a volume of a space in which an item is being placed to a volume of a space capable of receiving an item. Also, the item space usage rate may be a value changeable with performing a picking task on an item. As an example, when a zone includes five locations a, b, c, d, and e in which a space usage rate of an item A is ten percent (%), the item A may be gathered through the consolidation task so as to be placed in one location, for example, the location a. Through this, in the location a, the space usage rate of the item A may be 50%. Also, the item A may be removed from the remaining four locations b, c, d, and e such that the locations are to be filled with other items. Also, the consolidation may be to move an item with a high order rate, for example, a fast-selling item to a location for an operator to easily pick the item, or to move an item with a low order rate, for example, a deadwood item to a separate location. For example, the consolidation task may be performed to move the fast-selling item to medium-height shelves, or move the deadwood item to a deadwood zone. Here, the deadwood item may be an item that has not been sold within last 30 days. Classification of the fast-selling item or the deadwood item based on an item's order rate may differ for each physical location (e.g., fulfillment center) for storing items to be delivered to customers. The item's order rate may be changed based on various factors such as a season, a place, a nation, a time zone, and the like. Thus, an item with a high order rate and an item with a low order rate may not be fixed. For example, an item such as an electric fan may be classified as the fast-selling item due to the high order rate in summer and classified as the deadwood item in winter. Thus, the electric fan may be stored in different locations according to seasons.
An operation system for inventory management according to the present disclosure may be based on random stow. The random stow may refer to a method for placing various items at various locations in storage spaces arranged in rows, not a system for placing items in zones preset for the respective items. The random stow may minimize movement of a worker in inbound and outbound areas, thereby significantly reducing a work time. In addition, unlike a general fulfillment center where spaces for storing items are designated, random stow enables placement of items without leaving any space empty, and therefore, random stow is efficient in terms of space management. An operation system for inventory management according to the present disclosure may refer to a system for recommending a space for displaying an item so that the space for displaying the item can be optimized under a random stow process.
Referring to FIG. 1, an operation system for inventory management may include a user terminal 10 and an electronic apparatus 20. FIG. 1 illustrates only components of the operation system 1 related to the present embodiment. However, it is apparent to those skilled in the art that other general-purpose components may be further included in the operation system 1 in addition to the components illustrated in FIG. 1.
The user terminal 10 and the electronic apparatus 20 may communicate with each other through a network 30. The network 30 may include any one or combinations of a local area network (LAN), a wide area network (WAN), a value added network (VAN), a mobile radio communication network, and a satellite communications network. Also, the network is a comprehensive data communication network that allows network components of FIG. 1 to smoothly communicate with each other, and may include a wired Internet, a wireless Internet, and a mobile wireless communication network. The wireless communication may be, for example, wireless fidelity (Wi-Fi) LAN, Bluetooth™, Bluetooth low energy, ZigBee, Wi-Fi direct (WFD), ultra wideband (UWB), infrared Data Association (IrDA) communication, and near field communication (NFC) but not is limited thereto.
The user terminal 10 may provide a platform for inventory management. Specifically, the user terminal 10 may receive a consolidation task request from a user as an input and transmit the consolidation task request to the electronic apparatus 20. For example, the user terminal 10 may receive information on a plurality of locations in which a consolidation task is required, or receive a target value of an item space usage rate for each zone. Also, the user terminal 10 may receive information on at least one item from the electronic apparatus 20 and provide the received information to the user. Here, the at least one item may be a target on which a picking task is to be performed. For example, the user terminal 10 may output information on an item and guide the user to perform a consolidation process on inventory items to be compressed. The user terminal 10 may provide task location information and identification and quantity information of an item to be picked, to the user through an application.
The user terminal 10 may request the user to input identification information associated with an item to be picked, a storage unit from which the item is to be picked, and a location in which the item to be picked is placed. In this disclosure, a term “picking target item” may refer to an item or target on which a picking task is to be performed and also refer to an item to be picked. When the information is received from the user, the user terminal 10 may perform the consolidation process. In this case, the user terminal 10 may also request the user to input identification information associated with another location differing from the location for which the input of the identification information is requested. In some cases, the identification information may be a barcode, RFID tag data, or the like. Also, in addition to the user terminal 10 (e.g., a tablet device, a mobile device, a device such as a PDA, a computer, and the like), the identification information may be scanned or read by an automated or portable barcode scanner, RFID reader, and high speed camera, for example. Related description will be made with reference to the following drawings.
The user terminal 10 may verify whether an item is picked by a quantity corresponding to a target quantity as the consolidation task progresses. For example, the user terminal 10 may request the user to input a quantity by which an item is picked at a location where the item is placed. Hereinafter, a quantity by which an item is picked may be referred to as a “picking quantity.” The user terminal 10 may request an input of terminating the consolidation task as a subsequent operation, or request the user to input identification information associated with another location differing from the location for which the input of the identification information is requested or identification information of another item differing from the item on which the picking task is performed. The user terminal 10 may then receive a picking task result of the picked item from the user and transmit the picking task result to the electronic apparatus 20.
The electronic apparatus 20 of the operation system 1 for the inventory management may receive the consolidation task request from the user terminal 10 and identify information on at least one item on which a picking task is to be performed, based on information changing in real time while the picking task is performed on the item. Related examples will be further described with reference to the drawings below. Meanwhile, the electronic apparatus 20 may receive the consolidation task request directly from the user not through the user terminal 10. In this case, the electronic apparatus 20 may receive information on a plurality of locations in which the consolidation task is required or directly receive a target value of an item space usage rate for each zone.
The user of the operation system 1 for the inventory management may identify an inventory management status using the electronic apparatus 20 in addition to the user terminal 10. The electronic apparatus 20 may provide the user with information on inventory updated in real time. For example, as the consolidation process progresses, the electronic apparatus 20 may update a consolidation plan, a consolidation status, and an error report of consolidation in real time based on a picking task result received from the user terminal 10 and provide a result of the updating to the user.
The electronic apparatus 20 of the present disclosure may be an apparatus included in a server for inventory management. When the picking tack is performed on the item in the zone, the server for inventory management may calculate the item space usage rate for each zone in real time. In response to the user picking items in locations in the zone, the item space usage rate for each zone may change in real time. Thus, even after information on an item to be picked is identified, the server for inventory management may consistently update the item space usage rate for each zone.
FIG. 2 is a diagram illustrating an item storing space, for example, a fulfillment center (FC) 200. The FC 200 may be an example of a physical location in which items to be delivered to customers are stored. The fulfillment center 200 may be divided into a plurality of zones. The respective zones are illustrated in FIG. 2.
An inbound zone 203 may be an area in which items are received in the FC 200 from sellers. For example, a seller may send items 202A and 202B using a truck 201. The item 202A may be a single item that is sufficiently large to occupy its transport pallet. The item 202B may be a set of items stowed on the same pallet to save a room.
An operator may receive items in the inbound zone 203 and check the items for damage and accuracy. For example, the operator may compare a quantity of each of the items 202A and 202B to an ordered quantity. When the quantity matches the ordered quantity, the operator may move the items to a buffer zone 205 (for example, manually or by using a dolly, a hand truck, or a forklift truck 206). The buffer zone 205 may be, for example, a temporary storage area for items not currently needed in a picking zone 209 because there is a sufficient quantity of such items in the picking zone 209 to satisfy a predicted demand.
A drop zone 207 may be an area of the FC 200 in which the items are stored before the items are moved to the picking zone 209. An operator allocated to a picking task may access the items 202A and 202B in the picking zone 209, identify an identifier (for example, a barcode) of the picking zone 209, and identify identifiers associated with the items 202A and 202B using a mobile device (for example, the user terminal 10). Thereafter, the operator may add the items to a cart or carry the items to take the items to the picking zone 209.
The picking zone 209 may be an area of the FC 200 in which an item 208 is stored in a storage unit 210. For example, in order to generate a space for placement, a user may pick an item in the picking zone 209 in accordance with a picking plan and place the item at an allocated location in the storage unit 210. In an example, the storage unit 210 may include at least one of a physical shelf, a bookshelf, a box, a tote, a refrigerator, a freezer, a refrigerated warehouse, and the like. In another example, the picking zone 209 may be composed of a plurality of floors. In still another cases, an operator or machine may move items to the picking zone 209 manually or in various ways including, for example, a forklift, an elevator, a conveyor belt, a cart, a hand truck, a dolly, an automated robot or device, and the like.
In response to an order made by a purchaser, the operator may retrieve at least one item 208 from the storage unit 210, identify an identifier on the item 208, and place the item on a transport mechanism 214. Thereafter, the item 208 may arrive at a packing zone 211 through the transport mechanism 214.
The packing zone 211 may be an area of the FC 200 related to packaging. In the packing zone 211, the item may be received from the picking zone and packaged in a box or bag for final shipment to 209 to the purchaser. A hub zone 213 may be an area of the FC 200 in which all packages including a package 218 are received from the packing zone 211. An operator and/or machine of the hub zone 213 may search for the package 218, determine a region to which each package is to be sent among delivery regions, and route the corresponding package to an appropriate camp zone 215. In some cases, an operator or machine may identify an identifier of the package in the camp zone 215 and determine a final destination. In the example of FIG. 2, the camp zone 215 may include a truck 222, a car 226, and delivery operators 224A and 224B.
The present disclosure relates to an example of picking an item mainly in the buffer zone 205 and the picking zone 209 of the FC 200. However, it is merely an example, and the picking task may also be performed in various zones.
FIG. 3 illustrates an example of receiving a consolidation task request according to an example embodiment. Although FIG. 3 illustrates that the consolidation task request is input through the user terminal 10, it is merely an example and the consolidation task request may also be input through the electronic apparatus 20.
An operation method for inventory management of the present disclosure may receive a consolidation task request through the user terminal 10 so that the electronic apparatus 20 receives the consolidation task request from the user terminal 10. The consolidation task request may be an operation of inputting information on a plurality of locations in which a consolidation task is required. Specifically, the information on a plurality of locations in which a consolidation task is required may include information on the plurality of locations and information on an item included in each of the locations. According to an example embodiment of the present disclosure, a user may input, to the user terminal 10, item information of an item which is a target for a consolidation task and location information of a location in which the item is placed, so that the information is transmitted to the electronic apparatus 20. For example, the user may extract location information of a location in which a consolidation task target item is placed and metadata associated with the consolidation task target item in a format of a computer-readable storage medium. Also, the user may upload the extracted location information and the metadata to the electronic apparatus 20 through the user terminal 10.
As shown in a screen 300 of FIG. 3, the user may select a purpose of creating a consolidation plan. For example, in a creation purpose input field 301, a plurality of options related to the purpose of creating the consolidation plan may be popped up in a list, so that the user selects a purpose related to inventory management from the list. Thereafter, the user may set a period for terminating a consolidation task in a task deadline selecting field 302. Here, a consolidation task deadline may not be limited and, when no deadline is selected, set to a default value. For example, a default value of the task deadline may be set to 23:59 the next day.
The user may then upload the item information of the consolidation task target item and the location information of the location in which the item is placed, to a plan creation field 303 in a form of a computer-readable storage medium. The user may download a template in which consolidation task data is to be recorded from the user terminal 10 in a form of a computer-readable storage medium, for example, a file. Also, the user may record the location in which the consolidation task target item is placed and the metadata associated with the consolidation task target item in the template, and upload the template to the plan creating field 303 in a form of the computer-readable recording medium, for example, in a form of a file.
According to an example embodiment of the present disclosure, the user terminal 10 may transmit data included in the uploaded file to the electronic apparatus 20 through the network 30. Thereafter, the electronic apparatus 20 of the present disclosure may recognize information on at least one item for performing a picking task based on the received data. In this instance, the electronic apparatus 20 may compare an item space usage rate of each of the plurality of locations to a predetermined value, thereby generating the information on or regarding at least one item on which a picking task is to be performed. Here, the predetermined value may be a default value of the item space usage rate for each zone set in a server before the consolidation task request is received.
The electronic apparatus 20 may select a plurality of locations belonging to a zone of which the item space usage rate for each zone is less than or equal to the default value. Also, the electronic apparatus 20 may identify an item placed in at least one location among the plurality of locations as the at least one item on which the picking task is to be performed, thereby generating information on the item. For example, when a default value of an item space usage rate for each of zones A, B, and C is set to 10%, and the item space usage rate in the respective zones are 13%, 19%, and 7%, the picking task may be performed in the zone C of which the item space usage rate is less than the default value.
Meanwhile, through the foregoing example, the user may directly select the item on which the consolidation task is to be performed. Also, the above-described example may be efficient in working with specific types of items such as a fast-selling item and a deadwood item in addition to the purpose of creating the space for placement. When it is difficult for the user to directly extract a large amount of data, or when it is necessary to work based on real-time data by reflecting a consolidation task status, a location may be automatically allocated in the system as described below.
In another example of receiving a consolidation task request, a target value of an item space usage rate for each zone may be received from a user. A description of such will be given with reference to FIG. 4.
FIG. 4 illustrates another example of receiving a consolidation task request. Referring to FIG. 4, a user may input a target value of an item space usage rate for each zone through the user terminal 10 or the electronic apparatus 20.
As shown in a screen 400 of FIG. 4, the user may input a target value of an item space usage rate for each zone in a target value setting field 401. In this example, the target value may not be set or may be set as a default value or a previously set target value as indicated in the target value setting field 401. When the target value of the item space usage rate for each zone is input, the electronic apparatus 20 may compare the input target value to the item space usage rate for each zone, thereby generating information on at least one item on which a picking task is to be performed.
In an example, the electronic apparatus 20 may select a plurality of locations belonging to a zone of which an item space usage rate for each zone is less than or equal to the target value. Also, the electronic apparatus 20 may identify an item placed in at least one location among the plurality of locations as at least one item on which a picking task is to be performed, thereby generating information on the item. For example, when the electronic apparatus 20 receives 20% as the target value of the item space usage rate for each of zones D, E, and F, and when the item space usage rates of the respective zones are 10%, 25%, and 17%, a picking task may be performed in the zones D and F other than the zone E of which the item space usage rate is greater than the target value.
Meanwhile, in the foregoing example, the user may not directly extract data and may perform a consolidation task based on data updated by a server in real time. Also, since the consolidation task may be performed based on the real-time data instead of a subjective decision of an operator, the user's convenience may increase and an inventory status changing in real time may be reflected.
An operation method for inventory management according to an example embodiment of the present disclosure may be to plan about which item is picked in a location of which zone. Related examples will be described with reference to FIGS. 5A and 5B.
FIGS. 5A and 5B illustrate screens representing an operation method for inventory management according to an example embodiment. Specifically, (a) through (j) of FIGS. 5A and 5B represent display screens of the user terminal 10 according to an example embodiment of an operation method for inventory management. Also, in cases of FIGS. 6 through 10, for convenience of description, display screens of the user terminal 10 may be shown. For this, the user terminal 10 may include units for performing an operation, for example, a display, an input device, a communication device, a processor, and the like. Descriptions of such will be given later.
According to an example embodiment, a user may select an item related to inventory management through an application about the operation system 1 for the inventory management in the user terminal 10, and select an item for initiating a picking task as shown in (a) and (b) of FIG. 5A. Also, the user terminal 10 may receive identification information of a storage unit in which a picked item is to be added as shown in (c) of FIG. 5A. In some cases, the storage unit may include units carried by a user such as a shelf, a bookshelf, a box, a tote, and the like, for example.
In response to a consolidation task request received in advance, the user terminal 10 may output information on at least one item on which a picking task is to be performed, received from the electronic apparatus 20. For example, information on an item may include identification information, quantity information, and location information of an item on which a picking task is to be performed. Among them, from the output location information, information on a task location in which a user is to perform a picking task (hereinafter, also referred to as “task location information”) may be received as shown in (d) and (e) of FIG. 5A. The task location information may correspond to information on a location in which a picking target item is placed. Also, the task location information may include detailed information on a location such as a zone in a fulfillment center in which the location corresponding to the task location information is located and an aisle included therein.
The user terminal 10 may provide a guide on the picking task based on the input task location information and output the identification information and the quantity information of the picking target item along with the task location information as shown in (f) of FIG. 5B. At this stage, the user terminal 10 may request to input identification information of a location in which a picking target item is placed. Meanwhile, when identifying the identification information of the location to input the identification information, a situation in which the identification is unavailable may occur. Related descriptions will be made with reference to FIG. 6.
FIG. 6 illustrates an example of requesting to input identification information of a location according to an example embodiment.
According to an example embodiment, when an identification of identification information of a location is unavailable as shown in (a) of FIG. 6, the user terminal 10 may transmit error information to the electronic apparatus 20. For example, when the identification is unavailable due to a damage of the identification information, the user terminal 10 may receive an input indicating that the identification information of the location is not identifiable as shown in (b) of FIG. 6 and transmit information on the location having an error to the electronic apparatus 20.
Also, in a case of receiving the input indicating that the identification information of the location is not identifiable as shown in (b) of FIG. 6, the user terminal 10 may output information on a different location and request to input identification information of the different location. The different location may be a location where the picking target item is placed and different from the location for which the input of the identification information has been requested immediately before. The different location may also be a location where the picking target item is placed and adjacent to the location for which the input of the identification information has been requested immediately before. The adjacent locations may be locations that are physically adjacent to each other, and may be locations belonging to a same area (e.g., a zone, an aisle, etc.) Hereinafter, for the term of “different location”, the above description may be referenced.
When the identification information of the location is identified without occurring an error, the user terminal 10 may output the identification information and the quantity information of the item on which the picking task is to be performed as shown in (g) of FIG. 5B. The identification information the item on which the picking task is to be performed may include, for example, a name of the item, a representative image of the item, and a SKU ID. Also, the quantity information of the item for performing the picking task may include information on a target quantity.
When the identification information of the location is identified without occurring an error, the user terminal 10 may request to input the identification information of the picking target item. In this case, a situation in which the identification information of the picking target item is not identifiable and may not be input to the user terminal 10 may occur. Related descriptions will be made with reference to FIG. 7.
FIG. 7 illustrates an example of requesting to input identification information of an item according to an example embodiment.
According to an example embodiment, when the identification information of the item is not identifiable as shown in (a) of FIG. 7, the user terminal 10 may transmit error information to the electronic apparatus 20. For example, when the identification information is damaged in a process of handling such as transporting and storing an item, an identification of the identification information may be unavailable. In this example, the user terminal 10 may receive a request indicating that the identification information of the item is not to be input as shown in (b) of FIG. 7. Also, the user terminal 10 may transmit information on an item having an error to the electronic apparatus 20.
Also, when the request indicating that the identification information of the item is not to be input is received as shown in (b) of FIG. 7, the user terminal 10 may output information on a different location and request to input identification information of the different location.
Meanwhile, when the identification information of the item is identified without occurring an error, the user terminal 10 may request to continue performing the picking task on the item in a task location. In general, one or more picking target items may be arranged in the task location, but an inventory status recorded in a server may be different from an actual inventory status. For example, there may be no item to be picked when a user arrives at the task location for the picking task. In this case, the user may not perform the picking task in the corresponding task location. Thus, an additional process for providing notification for such a situation may be required.
FIG. 8 illustrates an example of verifying whether a picking quantity of an item corresponds to a target quantity according to an example embodiment. Referring to FIG. 8, when a picking target item is absent in a task location as shown in (a) of FIG. 8, the user terminal 10 may receive an input indicating a quantity of an item placed in the task location is insufficient as shown in (b) of FIG. 8. When the input is received, the user terminal 10 may output information on a different location, thereby requesting a user to input identification information of the different location. In this case, the user may move to the different location and initiate the picking task of the picking task item again. Also, the user terminal 10 may transmit error information to the electronic apparatus 20 to deliver information indicating that the picking task of the item is unavailable.
Meanwhile, when one or more items are present in the task location, the user terminal 10 may request to input a quantity by which the picking target item is picked in the task location. In one embodiment, the user terminal 10 may receive an input indicating that the input picking quantity of the item does not correspond to a target quantity. A case in which the input picking quantity of the item does not correspond to the target quantity may be, for example, a case in which the picking of the item is unavailable due to an insufficient space of a storage unit or a case in which all items in the task location are picked but the picking quantity does not meet the target quantity. In such cases, the user may not be able to proceed with the picking task. An operation performed in such cases will be described with reference to FIGS. 9 and 10.
FIGS. 9 and 10 illustrate examples of verifying whether a picking quantity of an item corresponds to a target quantity according to an example embodiment.
In an example, when an empty space in a storage unit is smaller than a volume of a picking target item, picking of the item may be impossible. For example, when an actual volume or packaging of the picking target item is different from a record in a server, it may be difficult to add the item of the target quantity to the storage unit. In this case, the user terminal 10 may receive an input indicating that the picking task of the item is completed as shown in (a) of FIG. 9 and receive a reason for which the picking quantity of the item does not correspond to the target quantity (for example, the insufficient space in the storage unit) as shown in (b) of FIG. 9. Also, the user terminal 10 may request an input of terminating a consolidation task as shown in (c) of FIG. 9. At this time, the storage unit in which the consolidation task is terminated may be treated as being completed even if the picking quantity of the picking target item is less than the target quantity.
In another example, even when all items in the task location have been picked, the picking quantity may not reach the target quantity. In other words, because an actual quantity of an item in the task location is not equal to a quantity recorded in a server, even when all items in the task location are picked, the picking quantity may not reach the target quantity. For example, during an inbound process, a damaged item that is not registered on the server may be placed in the task location, so an item may not be picked by a target quantity in the task location. In this case, the user may input a quantity only as much as the quantity that can be input into the user terminal 10 (that is, only the quantity actually picked). The user terminal 10 may receive an input indicating that a picking quantity of a picking target item does not correspond to the target quantity as shown in (a) of FIG. 10. Also, the user terminal 10 may receive a reason for which the picking quantity of the item does not correspond to the target quantity (for example, an insufficient quantity of the item) as shown in (b) of FIG. 10. Additionally, the user terminal 10 may request to input identification information on a different location including the picking target item and being adjacent to the location for which the input of the identification information has been requested immediately before, or transmit error information to the electronic apparatus 20.
Referring back to FIG. 5B, the user terminal 10 may receive an input indicating that the picking quantity of the picking target item corresponds to the target quantity as shown in (h) of FIG. 5B. Also, the user terminal 10 may receive a picking task result of the picking target item and transmit the picking task result to the electronic apparatus 20. For example, the user terminal 10 may receive an input indicating that the picking task is completed and no more space for adding items remains as shown in (i) of FIG. 5B. In this case, the user terminal 10 may request an input of terminating the consolidation task as shown in (j) of FIG. 5B. Meanwhile, when the storage unit corresponds to a “tote”, a case in which no more space for adding items remains in the storage unit may be referred to as “tote full”, which may be used as a term for informing of completion of a picking task.
When the picking target item corresponding to the target quantity is picked, and when a space remains in the storage unit, the picking task may be additionally performed. An additional picking task may be a picking task for another item scheduled for a consolidation task, and may be a picking task for an item different from the item on which the picking task is completed. For this, the user terminal 10 may request to input identification information of an item different from the picking target item. The user terminal 10 may also output location information for picking the different item.
Although it has been mentioned that the user terminal 10 mainly performs the corresponding functions relating to various embodiments of the present disclosure, the present disclosure is not limited to thereto, and the functions may also be performed by the electronic apparatus 20.
The electronic apparatus 20 of the present disclosure may receive the picking task result from the user terminal 10 and update information on inventory. Based on the picking task result, the electronic apparatus 20 may update a consolidation plan, a consolidation status, a consolidation error list, and the like in real time.
Specifically, the electronic apparatus 20 may update a proceeding status of the picking task for each metadata associated with the picking target item and the location information of the location in which the picking target item is placed so that the consolidation plan is to be verified. For example, the proceeding status of the picking task may include a picking standby status, a picking status, a picking-completed status, a picking terminating status, and a picking-suspended status. The picking standby status may indicate a case in which a user has not yet started picking after the consolidation plan is generated. The picking status may indicate a case in which one or more items are picked after the consolidation plan is generated. The picking-suspended status may indicate a case in which the user notifies a suspension of the picking through the user terminal 10 or the electronic apparatus 20 in the picking-standby or picking status. The picking-completed status may indicate a case in which an item is picked by a quantity corresponding to a target quantity. The picking-terminating status may indicate a case in which a picking deadline (for example, a task deadline) has arrived while the picking is not completed.
The electronic apparatus 20 may update a picking and display status for each storage unit so as to track the storage unit in which a picking target item is picked and stored. For example, the picking and display status may include a picking status, a display standby status, a displaying status, and a display-completed status. The picking status may indicate a state in which one or more items are added to the storage unit and the storage unit has a space for the items. The display standby status may indicate a state of waiting for displaying because the storage unit has no more space for adding an item. The displaying status may indicate a state in which a display task has been actually completed but information on the completion is not transmitted to a server. The display-completed status may indicate a state in which the storage unit on which the picking task has been completed is displayed. Also, the electronic apparatus 20 may output picking and display status information for each storage unit based on the updated picking and display status. For example, for each storage unit, information on a picking quantity of a picking target item, a status of the storage unit, a picking task processing time, an operator, and the like may be output.
The electronic apparatus 20 may update the error information received from the user terminal 10 in a consolidation error list. As described with reference to FIGS. 6 through 8 and 10, the electronic apparatus 20 may receive the error information from the user terminal 10 in various error situations. For example, a case in which the identification information of the location is not identifiable, a case in which the identification information of the item is not identifiable, a case in which a picking target item is absent in the task location, and a case in which all items in the task location have been picked but a picking quantity does not reach a target quantity may correspond to the error situation. Such error information may include information associated with an error report date and time, an error type, information on a location and item in which an error occurs (metadata, an identifier, an item name, etc.) and a quantity with problems, for example.
Hereinafter, an operation method for inventory management of the present disclosure will be described in detail with reference to the following flowcharts.
FIG. 11 is a flowchart illustrating an operation method of the electronic apparatus 20 for inventory management according to an example embodiment of the present disclosure and FIG. 12 is a flowchart illustrating an operation method of an inventory management system according to an example embodiment of the present disclosure.
