Description

[Technical field]

[0001] An embodiment of the present invention relates to an information processing device and an information processing program. [Background technology]

[0002] In recent years, shopping proxy services such as online supermarkets, where customers order products via the Internet and pick them up at their home or other location at the time of their choice, are becoming more and more popular. In such shopping proxy services, a picker picks up the products ordered by the customer from a store or warehouse, and a delivery person delivers the picked up products to the customer's home or other location.

[0003] However, in conventional services, the picking order is left to the discretion of the worker, and this can take a lot of time for inexperienced workers.

[0004] Therefore, there is a need for a picking operation support system that can present the picking order and make the picking work more efficient. [Prior art documents] [Patent documents]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] (Embodiment) Hereinafter, the embodiments will be described with reference to the drawings. In the drawings, the same components are denoted by the same reference numerals as much as possible, and duplicated explanations will be omitted.

[0010] (Configuration example) FIG. 1 is a block diagram illustrating a picking operation support system 100 according to an embodiment. The picking operation support system 100 includes a server 1, a picking terminal 2, and an ordering terminal 3. The server 1, the picking terminal 2, and the ordering terminal 3 are connected to each other via a network so as to be able to communicate with each other freely. For example, the network is configured with one or more of various networks such as the Internet, a mobile communication network, and a LAN (Local Area Network). The one or more networks may include a wireless network or a wired network. The picking operation support system 100 may also refer to a system including at least two of the devices of the server 1, the picking terminal 2, and the ordering terminal 3.

[0011] The server 1 is a device that collects data and processes the collected data. The server 1 is connected to the picking terminal 2 and the ordering terminal 3 via a network so as to be able to communicate freely. The server 1 receives various data from the picking terminal 2 and the ordering terminal 3, and outputs various data to the picking terminal 2 and the ordering terminal 3. The server 1 is an example of an information processing device. An example of the configuration of the server 1 will be described later.

[0012] The server 1 provides a shopping agent service. For example, the shopping agent service accepts product orders from customers via the order terminal 3, and assigns pickers to pick up the products according to the orders. Picking up is also called picking. The picker picks the products included in the multiple orders within a delivery time frame. The picker picks at least one order. The multiple orders indicate multiple orders that require the picking work to be completed within a predetermined delivery time frame. Each of the multiple orders includes at least one product. The delivery time frame is, for example, a time frame that divides the delivery time by a predetermined time interval. The delivery time frame is, for example, a time frame in increments of one hour or two hours. The delivery time frame is, for example, "11:00 to 13:00", "13:00 to 15:00", "15:00 to 17:00", etc. In one delivery time frame, multiple pickers pick the products included in the multiple orders. For example, when one order includes multiple items, the same picker picks the multiple items. Note that different pickers may pick some of the multiple items included in one order. The shopping agent service assigns multiple orders included in one delivery time frame to multiple pickers. The pickers use shopping carts to pick items in the store and place the picked items in baskets loaded into the shopping cart. The shopping cart is also simply called a cart. The specified delivery time frame is an example of a specified time. The picker may be interpreted as an operator, a person in charge, or a worker.

[0013] The number of baskets required to pick an order varies depending on the number of items and their volume. A picker may pick two or more orders simultaneously in one picking operation (one trip), sorting them by order. The total number of baskets for orders picked by the same picker at the same time (in one trip) must not exceed the number of baskets that can be loaded into a cart. A picker cannot split an order into multiple trips for picking. One order refers to a single order placed by a customer.

[0014] One order includes at least one product. One order includes one product list. One trip indicates that a picker uses one cart to go around the store. One cart is loaded with a predetermined number of baskets. The predetermined number is, for example, three. For example, one picker performs one picking trip in a store during a certain delivery time frame by using one cart to put products into three baskets. Picking in one trip includes picking of products included in at least one order. One picker may perform two or more picking trips in a store during a certain delivery time frame.

[0015] The picking operation will be described. FIG. 2 is a conceptual diagram for explaining a picking operation according to the embodiment. FIG. 2 includes, for example, a list in which a plurality of orders received from a plurality of customers are arranged by delivery time frame. The list includes a delivery time frame, an order ID, a delivery address, a product list, and the like. The delivery time frame indicates a time frame in which a customer of each order desires delivery. The order ID is unique identification information assigned to each order in order to identify each order individually. The order ID is identification information attached to each order. The delivery address is information indicating a location where a customer desires delivery. The delivery address is, for example, the address of the customer based on the user information of the customer. The delivery address may be an address registered when the customer places an order. In the following description, "registration" may be read as "input". The product list indicates a list of products included in one order. One order can be read as one order by a customer. One order includes a series of processes from when a customer uses a shopping agent service to order a product, to when the customer pays for the product, or when the order is completed. One order includes processes from when the order is started to when the order registration is completed. The completion of the order registration indicates that the customer has performed a payment operation for the product or a completion operation for the order. For example, in response to the customer performing an order registration completion operation via the ordering terminal 3, the server 1 acquires an order registration completion instruction from the ordering terminal 3.

[0016] In the example of FIG. 2, there are nine orders with order IDs "O0001" to "O0009" during the delivery time frame "11:00 to 13:00". For example, the server 1 assigns the nine orders with order IDs "O0001" to "O0009" during the delivery time frame "11:00 to 13:00" to three pickers 01 to 03. In the example of FIG. 2, the picking work of the products with order IDs "O0001", "O0003", and "O0004" is assigned to picker 01. The picking work of the products with order IDs "O0002", "O0006", and "O0007" is assigned to picker 02. The picking work of the products with order IDs "O0005", "O0008", and "O0009" is assigned to picker 03. In the following explanation, it is assumed that the picking work is performed in one store.

[0017] Returning to the explanation of Figure 1. The picking terminal 2 is a device capable of communicating with other devices. The picking terminal 2 is, for example, a device used by a picker who performs picking work to pick up products in a store or the like in response to a customer's order. For example, the picker performs picking work based on an allocation image displayed on a display device of the picking terminal 2. For example, the picking terminal 2 is a PC (Personal Computer), a smartphone, a tablet terminal, or the like. The picker may be interpreted as an operator, a worker, a store clerk, a staff member, a user, or a person. The picker is an example of a user of the picking terminal 2.

The product information may be updated as appropriate by an administrator or the like.

[0030] In the example of Fig. 5, "XX Milk" of product ID "P0001" indicates that the picking location is "L0011." In the example of Fig. 5, the picking location corresponds to the location ID.

[0031] Product information may include information indicating the product category, volume, weight, picking load, etc. Examples of categories include fresh produce, meat, dairy products, etc. The category may also be a category related to the display position or sales area of ​​the product in the store. Volume is information that indicates an estimate of the size of the product. For example, the volume is calculated for each product as (the reciprocal of the number that can fit in a shopping basket) x 100. For example, if the volume of a shopping basket is 100, then 10 items with a volume of 10 can fit in the basket. Note that a shopping basket is a container that is loaded onto a cart used by a picker, and is not limited to a basket.

[0032] The picking load is information indicating the load of a worker for picking one item. The picking load is, for example, information indicating the workload based on item information. The item information is, for example, the display position of the item, the weight of the item, the volume of the item, and the like. For example, the picking load of a reference item is set to "1". The reference item includes, for example, an item located near the middle of a display shelf. The reference item includes an item that is equal to or less than a predetermined weight. The reference item includes an item that is equal to or less than a predetermined volume. A value greater than 1 may be set for an item whose picking load is higher than the reference, such as an item that is displayed in a distant location, an item that is difficult to find, or an item that is heavy and burdensome. The picking load may be set based on the distance from the position of the reference item to the display position of the item, the difference from a predetermined weight, the difference from a predetermined volume, and the like. The picking load may be registered in advance by an administrator, etc. The picking load may be updated as appropriate by an administrator, etc. The picking load may be variable depending on the attributes of the picker, etc. For example, the picking load may be weighted based on the picker's gender, age, build, years of experience, etc. The picking load may be variable based on the picker's work ability, etc.

[0080] FIG. 9 is a flowchart showing an example of a procedure for information processing regarding a picking order by the server 1 according to the embodiment. The following process is an example of specific information processing for determining a picking order in ACT3 shown in Fig. 8. In this example, a picking order is determined for at least one item included in an order for which each picker is to perform picking work. In the following process, a picking order is determined for multiple items included in one order, but the following process can also be applied to the case of determining a picking order for multiple items included in multiple orders.

[0081] The determination unit 112 calculates the distance between the positions of two products among the multiple products included in the order (ACT11). In ACT11, for example, the determination unit 112 calculates the distance between the positions of the two products for all combinations in which two products are taken out of the multiple products included in the order. The determination unit 112 may calculate the distance between the positions of the two products based on the travel time calculation program 1300. The distance between the positions of the two products is also referred to as the distance between two points. The determination unit 112 stores the calculated distance between the two points in the auxiliary storage device 13. The determination unit 112 calculates the travel time between the two points based on the distance between the two points. The determination unit 112 stores the calculated travel time between the two points in the travel time information 1312.

[0082] The determination unit 112 determines a route to be applied from among candidates for routes for picking all of the items to be picked (ACT12). In ACT12, for example, the determination unit 112 may determine, from among the candidate routes, a route with the shortest travel distance as the route to be applied. The determination unit 112 may determine, from among the candidate routes, a route with the shortest travel time as the route to be applied.

[0084] FIG. 10 is a flowchart showing an example of a procedure for information processing regarding picking orders by the server 1 according to the embodiment. The following process is an example of a specific information process for calculating the distance between two points in ACT11 shown in FIG.

[0085] The determination unit 112 acquires map information of the inside of the store from the map information 1310 (ACT21). In ACT21, for example, the determination unit 112 acquires map information of the store where the picking work is performed. In this example, the determination unit 112 acquires map information in a grid map format. Note that the map information is not limited to information in the grid map format. The map information may be information that indicates the position information of the product in the store.

[0086] The determining unit 112 converts the map information into graph structure data (ACT 22).

[0087] The determination unit 112 performs the following process for all combinations of two products taken from a plurality of products included in an order. In the following description, the process performed for the two taken products will be described.

[0088] The determination unit 112 acquires information on the picking positions of the two products from the product information 1311 (ACT23).

[0089] The determination unit 112 calculates the travel distance based on the information on the picking positions of the two products (ACT24). In ACT24, for example, the determination unit 112 calculates the shortest route for picking up the two products based on the information on the picking positions of the two products. The determination unit 112 calculates the travel distance between the picking positions of the two products based on the shortest route. The determination unit 112 may calculate the travel distance between the picking positions of the two products based on the position information of the two products. The travel distance between the picking positions of the two products is also referred to as the travel distance between the two products. The determination unit 112 may calculate the shortest route using a known technique such as a breadth-first search algorithm. In this case, the determination unit 112 sets the nodes corresponding to the picking positions of the two products as the start point and the end point of the graph structure data of the map information, respectively, and calculates the travel distance of the shortest route using a breadth-first search algorithm.

[0090] The determination unit 112 calculates the travel time between the two products (ACT25). In ACT25, for example, the determination unit 112 calculates the travel time between the two products based on the calculated travel distance of the shortest route between the two products. The determination unit 112 may calculate the travel time by multiplying the calculated travel distance of the shortest route between the two products by a travel time coefficient ((travel time)=(travel distance)×(travel time coefficient)). The travel time coefficient is a coefficient for converting the travel distance into travel time. The travel distance is, for example, the number of grids in the map information. The travel time is, for example, the number of seconds. The travel time coefficient can be set in consideration of, for example, the scale of the map, the travel speed, etc. The determination unit 112 calculates the travel time of the shortest route between the two products.

[0091] The determination unit 112 stores the calculated travel time of the shortest route between the two products in the travel time information 1312 (ACT26). The determination unit 112 can update the travel time information 1312 every time the travel time is calculated.

[0092] FIG. 11 is a flowchart showing an example of a procedure for information processing regarding picking orders by the server 1 according to the embodiment. The following process is an example of a specific information process for calculating a route between two products in ACT12 shown in FIG. In the following, an example will be described in which the processor 11 formulates an optimization problem, registers the formulated problem in the optimization program 1302, and obtains a solution to the formulated problem through processing based on the optimization program 1302.

[0093] The determination unit 112 acquires travel time information for all combinations of two products taken out from the multiple products included in the order (ACT31). In ACT31, for example, the determination unit 112 refers to the travel time information 1312 and acquires travel time information between two products for the multiple products included in the order. A case will be described in which the products included in the order are product P0005, product P0011, and product P0054. The determination unit 112 acquires travel time information between products AB when product A is "product P0005" and product B and "product P0011". The determination unit 112 acquires travel time information between products AB when product A is "product P0005" and product B and "product P0054". Similarly, the determination unit 112 acquires travel time information between product A and other products when product A is "product P0011" and travel time information between product A and other products when product A is "product P0054".

[0094] The determination unit 112 registers the decision variable in the optimization program 1302 (ACT32). In ACT32, for example, the determination unit 112 adjusts the decision variable "x ij ", "u j Define the decision variable x ij " is a binary variable that is 1 if the product i (i = 1, 2, ..., m) and product j (j = 1, 2, ..., n) are moved from the picking position of product i to the picking position of product j, and 0 if they are not moved. The decision variable "u j " is a variable that indicates the order in which product i is picked.

[0095] The determination unit 112 registers a constant in the optimization program 1302 (ACT33). In ACT33, for example, the determination unit 112 registers a constant "c ij Set the travel time information to "c". ij " is a constant that represents the cost of moving between two products. The cost of moving indicates the distance or time required to move.

[0096] The determination unit 112 registers the objective function and the constraint conditions in the optimization program 1302 (ACT34). The objective function is expressed by, for example, Equation 1.

[0101] The determination unit 112 determines the picking order of the multiple products included in the order (ACT 35). In ACT 35, for example, the determination unit 112 solves an optimization problem formulated as a mixed integer programming problem such as Equation 1, Equation 2, Equation 3, and Equation 4 by the optimization program 1302. The determination unit 112 determines the order in which the products included in the order will be picked, "u j The determination unit 112 determines a picking sequence in which a route for picking up a plurality of products included in an order is the shortest route.

[0102] The determination unit 112 stores the picking order of the multiple products included in the order in the picking task information 1313 (ACT36).

[0103] According to this example, the server 1 can determine the picking order of the products to be picked based on the position information between two products. The server 1 can determine the picking order that provides the shortest picking route. This allows the server 1 to provide the picking terminal 2 with the picking order for picking multiple products via the shortest route. The picker can perform the picking work based on the picking order, thereby making the picking work more efficient.

[0104] The above-mentioned picking order determination process has been described as a method of formulating the problem as a mixed integer programming problem and finding a solution using a mathematical optimization program, but the formulation method and the solution finding method are not limited to this. For example, a method of conducting a brute force investigation of all candidates for allocation of picking workers, a method of formulating the problem as an Ising problem and finding a solution using an Ising machine, or a method using a heuristic algorithm may be used.

[0105] A display example of a picking task displayed on the picking terminal 2 will be described. FIG. 12 is a diagram showing an example of a picking order image displayed on the display device 27 of the picking terminal 2 according to the embodiment.

[0106] FIG. 12 shows a picking order image Ima. The picking order image Ima includes a map display area Ara and a product information display area Arb. The map display area Ara is an area that displays a map of the store. The map display area Ara includes information indicating the position of a product included in an order on a map of the store. The information indicating the position of the product may be information indicating a position where the product is to be picked up. The information indicating the position of the product includes, for example, an object indicating the position of the product. The object indicating the position of the product is also called a product position object. The map display area Ara includes product position objects Oba, Obd, and Obf. The map display area Ara includes information indicating a route for picking up the product. The information indicating the route is information indicating which aisle on the map of the store to move through. The information indicating the route includes, for example, a route object. The route object may include a completed route object indicating a route from the start of picking to a product that has already been picked up, and an incomplete route object indicating a route for picking up a product that has not been picked up. The map display area Ara includes a completed path object Obe, and incomplete path objects Obb and Obg. The completed path object and the incomplete path object may be displayed in a manner that allows each to be distinguished. For example, the completed path object and the incomplete path object may be displayed in a manner that allows visual distinction. The manner that allows visual distinction includes different colors, sizes, brightness or luminance, patterns, or blinking displays. The incomplete path object Obb indicates the picking position of the previously picked product and the movement path to the picking position of the next product to be picked.

[0107] The map display area Ara may include information indicating the next product to be picked. The information indicating the next product to be picked is, for example, a product position object Obc. The product position object Obc may be displayed in a manner that allows visual distinction from other product position objects. In the example of FIG. 12, the product position object Obc is an arrow object. The arrow object indicates which direction of the display shelf the product is located in in the aisle. This allows the user of the picking terminal 2 to know which shelf the product is displayed on as seen from the aisle. The product position object may include detailed information on the display position of the product, such as the direction of the display position of the product from the starting point of the aisle, and the number of the display shelf. The detailed information on the display position of the product includes information that makes it easier for the picker to find the product. The detailed information on the display position of the product may be text information.

[0108] The map display area Ara displays a route according to the picking order of the products on the map. This allows the user of the picking terminal 2 to visually grasp which aisle to take when picking up the products based on the map of the store.

[0109] The server 1 may acquire the position information of the picking terminal 2. The position information of the picking terminal 2 may include position information acquired by a sensor or the like, and information indicating the orientation. In this case, the map display area Ara may include information indicating the current position of the picking terminal 2 and information indicating the orientation. The map display area Ara may display an image in which the orientation of the map is rotated based on the position information of the picking terminal 2. The server 1 may recalculate the picking order based on the position information of the picking terminal 2 when the user of the picking terminal 2 deviates from the route according to the picking order, or picks up products in an order different from the picking order. The server 1 may newly display a route according to the calculated picking order. According to this example, the server 1 can dynamically present a picking route according to the operation of the user of the picking terminal 2. This allows the server 1 to improve the efficiency of the picking work according to the operation of the user of the picking terminal 2.

[0110] The product information display area Arb includes product information of the picking target product to be picked next. The product information display area Arb includes an area Ta indicating the picking order, an area Tb indicating the product information, an area Tc displaying the product image, and a registration button Ba. The area Ta includes text information indicating the picking order. The area Tb may include the product name, the product ID, and the price. The area Tc may include the product image, a photo, or the like. The registration button Ba is a button operated by the user of the picking terminal 2. The registration button Ba is a software key. The registration button Ba is an operator for instructing the completion of the product registration. When the user of the picking terminal 2 completes picking of the picking target product, the user selects the registration button Ba by touch input or the like. The picking terminal 2 outputs information indicating the completion of the product registration to the server 1 based on the operation of the registration button Ba. Based on the touch input of the registration button Ba by the user, the picking terminal 2 may display the product information of the picking target product to be picked next in the product information display area Arb.

[0111] FIG. 13 is a diagram showing an example of a picking order image displayed on the display device 27 of the picking terminal 2 according to the embodiment.

[0112] FIG. 13 shows a picking order image Imb. The picking order image Imb shows a list of products to be picked. The list of products to be picked is a list in which product information of products is arranged according to the picking order. In the example of FIG. 13, a list is shown in which product information of products to be picked is arranged in ascending order from picking order 1. The picking order image Imb includes an area Td showing the picking order, an area Tf showing product information, an area Te displaying an image of the product, an area Tg and an area Th showing the registration status of the product, and a registration button Bb. The area Td includes text information showing the picking order, similar to the area Ta of FIG. 12. The area Te may include an image or a photo of the product, similar to the area Tc of FIG. 12. The area Tf may include a product name, a product ID, and a price, similar to the area Tb of FIG. 12. The area Tg and the area Th showing the registration status of the product may include text information showing the registration status of the product. The registration status of the product includes, for example, registration complete, not registered, next picking target, etc. Registration complete indicates that the product has been picked and registered. Registration complete indicates that the user has picked the product and stored it in a cart or the like. Registration complete indicates that the user has operated the registration button. Product registration may indicate that picking of the product has been completed. Not registered indicates that the product has not been picked. The next item to be picked indicates that the next picking order after the product most recently registered has been assigned based on the picking order. Text information indicating the registration status includes, for example, "Done", "NEXT", etc. Registration button Bb is the same button as registration button Ba.

[0113] The picking order image Imb may display information on products for which registration has been completed, information on products that have not yet been registered, and information on products to be picked next in a distinguishable manner. Therefore, the user of the picking terminal 2 can easily visually confirm the registration status of products from the list of products to be picked. This allows the user to easily visually confirm the product to be picked next. In this way, the server 1 can make the picking work more efficient.

[0114] The picking order image Imb may be updated based on a user's operation to register a product. The picking order image Imb may be displayed as a pop-up display when the picking order image Ima is displayed based on a user's operation. The picking order image Imb may be displayed in place of the picking order image Ima based on a user's operation.

[0115] The information processing related to the display of the picking order in the picking terminal 2 will be described. 14 is a flowchart showing an example of a procedure of information processing by the picking terminal 2 according to the embodiment. In this example, a procedure of information processing executed by the picking terminal 2 based on acquiring picking task information from the server 1 will be described.

[0116] In the following process, a picking order image is generated based on a picking operation of the picking target products by a user of the picking terminal 2. In this example, the picking terminal 2 updates the registration status of the picking target products based on a registration operation of the picking target products by the user.

[0117] The acquisition unit 210 acquires information on picking work according to a picking order of multiple products included in the order from the server 1 (ACT41). In ACT41, for example, the acquisition unit 210 acquires picking task information and map information from the server 1. The acquisition unit 210 may acquire product information of multiple products included in the order from the server 1.

[0118] The image processing unit 211 acquires information on product x with the smallest picking order based on the picking task information (ACT42). Product x indicates the picking target product to be picked next. In ACT42, for example, the image processing unit 211 extracts information on product x, which is the one product with the smallest picking order among products whose picking has not been completed based on the picking task information. The information on product x includes information indicating the position of the product. The information on product x includes product information on product x.

[0119] The image processing unit 211 generates a picking order image (ACT43). In ACT43, for example, the image processing unit 211 generates a picking order image including route information from the position of the product y to the position of the product x. The product y indicates the product that has been previously picked. The product that has been previously picked indicates the product that has been most recently picked. The product that has been most recently picked indicates the product whose picking order is one less than the next picking order. The picking order image includes a store map image. The route information may include a product position object indicating the position of the product x and the product y, and a route object indicating the route from the position of the product y to the position of the product x. Note that when the picking order of the product x is "1", the route information indicates the route from the entrance of the store to the position of the product x. The image processing unit 211 may generate a product information image indicating the product information of the product x based on the picking task information and the product information of the product x. The product information image may include, for example, an image indicating the picking order of the product, a product image, a product name, a product ID, a price, and a product registration status.

[0120] The display processing unit 212 displays an image related to the picking work according to the picking order on the display device 27 (ACT44). The image related to the picking work includes an image showing information about the product x and an image showing information about the picking order. In ACT44, for example, the display processing unit 212 displays the picking order image generated by the image processing unit 211 on the display device 27. The display processing unit 212 may display the product information image generated by the image processing unit 211 on the display device 27.

[0121] The registration processing unit 213 acquires a registration completion notification of the product to be picked by the user (ACT45). In ACT45, for example, the registration processing unit 213 acquires the registration completion notification based on the product registration operation by the user. The registration processing unit 213 updates the registration status of the product whose registration has been completed.

[0122] The registration processing unit 213 determines whether or not registration has been completed for all of the products to be picked (ACT46). In ACT46, for example, the registration processing unit 213 may refer to the product registration status based on the picking task information and determine whether or not registration has been completed for all of the products. If the registration processing unit 213 determines that registration has been completed for all of the products, the process transitions from ACT45 to ACT46. If the registration processing unit 213 determines that registration has been completed for all of the products, the processor 21 repeats the processes from ACT42 to ACT46.

[0123] The output unit 214 outputs a work completion notification to the server 1 (ACT47).

[0124] The image processing unit 211 may generate a picking order image including position information of all picking target products and information on a route for picking all picking target products, based on information on the picking work according to the picking order acquired from the server 1. The display processing unit 212 may display the product information image generated by the image processing unit 211 on the display device 27. The image processing unit 211 may update the picking order image based on a product registration completion operation by the user.

[0125] According to this example, the picking terminal 2 can display an image that allows the picker to visually recognize the picking order of the items to be picked. Therefore, even a picker who is not familiar with the store or items can move efficiently through the store using the shortest route and quickly find the items. In this way, the picking terminal 2 can make the picking work more efficient.

[0126] (Modification) The multiple orders may be orders for multiple stores. In this case, the allocation processing unit 111 may allocate the multiple orders within a predetermined delivery time frame for each store to multiple pickers.

[0127] In the above-described embodiment, the user of the picking terminal 2 completes the registration of the product to be picked by pressing a registration button, but the registration may also be completed by scanning the product code of the product using a camera or scanner of the picking terminal 2.

[0128] In the above embodiment, the method of registering map information within a store is occupancy grid map data, but other types of data such as graph structure data may also be used.

[0129] In the above embodiment, the output unit 113 of the server 1 has been described as outputting information related to the picking work to the picking terminal 2, but this is not limited thereto. The output unit 113 of the server 1 may output information for printing an image based on the information related to the picking work to a printer or the like. The printer or the like may print an image based on the information related to the picking work based on the acquired information.

[0130] (effect) The server 1 according to the embodiment can acquire information regarding the positions of multiple products included in an order, determine a picking order for picking the multiple products based on the information regarding the positions, and output information regarding the picking work according to the picking order. For example, the server 1 outputs the picking order determined based on the positions of the multiple products to the picking terminal 2. A user of the picking terminal 2 can perform the picking work based on the picking order. This allows the server 1 to make the picking work more efficient.

[0131] The server 1 according to the embodiment can output information on a route according to a picking order. For example, the server 1 outputs information on a route according to a picking order to the picking terminal 2. A user of the picking terminal 2 can perform a picking operation based on the route. This allows the server 1 to make the picking operation more efficient.

[0132] The server 1 according to the embodiment can determine a picking order in which the route for picking a plurality of products is the shortest route. For example, the server 1 outputs information on the shortest route for performing the picking work to the picking terminal 2. The user of the picking terminal 2 can perform the picking work based on the shortest route. This allows the server 1 to make the picking work more efficient.

[0133] The server 1 according to the embodiment can output information associating a picking order with product information of multiple products. For example, the server 1 outputs information associating a picking order with product information of multiple products to the picking terminal 2. A user of the picking terminal 2 can perform a picking operation based on information about the product to be picked next according to the picking order. For example, the user can search for the product to be picked based on the product name or image of the product to be picked next. This enables the server 1 to make the picking operation more efficient.

[0134] The picking terminal 2 according to the embodiment can display an image related to a picking operation according to a picking order in which a plurality of products are to be picked. For example, a user of the picking terminal 2 can perform a picking operation based on the picking order. This allows the picking terminal 2 to make the picking operation more efficient.
