INFORMATION PROCESSING DEVICE, INFORMATION PROCESSING METHOD, COMPUTER PROGRAM PRODUCT, AND INFORMATION PROCESSING SYSTEM
According to an embodiment, an information processing device includes one or more hardware processors configured to, based on a plurality of pieces of rack data including first identification information of one or more kinds of products housed in each of a plurality of racks, determine: a processing sequence of a plurality of pieces of order data including second identification information of one or more kinds of products to be picked from at least part of the plurality of racks; and one or more of the plurality of racks for picking a product identified by the second identification information for each of the plurality of pieces of order data.
1 . An information processing device comprising
one or more hardware processors configured to, based on a plurality of pieces of rack data including first identification information of one or more kinds of products housed in each of a plurality of racks, determine: a processing sequence of a plurality of pieces of order data including second identification information of one or more kinds of products to be picked from at least part of the plurality of racks; and one or more of the plurality of racks for picking a product identified by the second identification information for each of the plurality of pieces of order data.
2 . The device according to claim 1 , wherein the one or more hardware processors are configured to
for each of the plurality of racks, calculate a higher priority as a number of pieces of first identification information that matches the second identification information included in the plurality of pieces of order data is greater, and
for the order data including the second identification information that matches the first identification information included in a rack selected in sequence from a highest priority, determine the selected rack as the one or more of the plurality of racks for picking the product identified by the second identification information.
3 . The device according to claim 1 , wherein the one or more hardware processors are configured to further output information indicating at least one selected from: a number of picking works for each of the plurality of racks; and time for the picking works, which are calculated based on a ratio at which the products assigned to the order data are picked from a single rack.
4 . The device according to claim 1 , wherein the one or more hardware processors are configured to generate, respectively for the plurality of pieces of order data, indexes each indicating one or more racks for picking the products among racks housing products of the first identification information that matches the second identification information, based on a priority calculated for each of the plurality of racks, and determine the processing sequence using the generated indexes.
5 . The device according to claim 4 , wherein the one or more hardware processors are configured to
calculate distances between the indexes generated respectively for the plurality of pieces of order data, and
determine the processing sequence such that turns are closer as a calculated distance is smaller.
6 . The device according to claim 5 , wherein the one or more hardware processors are configured to determine the processing sequence by executing hierarchical clustering in which processing of merging the order data corresponding to indexes with a small distances into a cluster are repeated, and performing recursive expansion such that child clusters having a common parent cluster are adjacent to each other.
7 . The device according to claim 1 , wherein the one or more hardware processors are configured to implement a determination unit configured to determine the processing sequence, and the one or more of the plurality of racks for picking the product identified by the second identification information for each of the plurality of pieces of order data.
8 . The information processing device according to claim 1 , wherein the one or more hardware processors are configured to output the processing sequence, and the one or more of the plurality of racks determined for each of the plurality of pieces of order data.
9 . The device according to claim 1 , wherein the plurality of racks are movable to a work station where housing containers corresponding to each of at least part of the plurality of pieces of order data are disposed.
10 . The device according to claim 1 , wherein the one or more hardware processors are configured to determine, based on the plurality of pieces of rack data, the processing sequence and the one or more of the plurality of racks for picking the product identified by the second identification information for each of the plurality of pieces of order data such that a ratio at which the products assigned to the plurality of pieces of order data are picked from a single rack is improved.
11 . An information processing method executed by the information processing device, the information processing method comprising, based on a plurality of pieces of rack data including first identification information of one or more kinds of products housed in each of a plurality of racks, determining: a processing sequence of a plurality of pieces of order data including second identification information of one or more kinds of products to be picked from at least part of the plurality of racks; and one or more of the plurality of racks for picking a product identified by the second identification information for each of the plurality of pieces of order data.
12 . A computer program product comprising a computer-readable medium including programmed instructions, the instructions causing a computer to execute, based on a plurality of pieces of rack data including first identification information of one or more kinds of products housed in each of a plurality of racks, determining: a processing sequence of a plurality of pieces of order data including second identification information of one or more kinds of products to be picked from at least part of the plurality of racks; and one or more of the plurality of racks for picking a product identified by the second identification information for each of the plurality of pieces of order data.
13 . An information processing system comprising: a transfer device, an information processing device, and a work station, wherein
the transfer device is configured to transfer a plurality of racks housing products to the work station, and
the information processing device includes one or more hardware processors configured to, based on a plurality of pieces of rack data including first identification information of one or more kinds of products housed in each of the racks, determine: a processing sequence of a plurality of pieces of order data including second identification information of one or more kinds of products to be picked from at least part of the plurality of racks; and one or more of the plurality of racks for picking a product identified by the second identification information for each of the plurality of pieces of order data.
