Abstract

Claims (28)

1. A shelf storage management system comprising:

a plurality of shelf tiers in an area;

a worker terminal comprising:

at least one terminal memory storing terminal program code; and

at least one terminal processor configured to access the terminal program code and to operate as instructed by the terminal program code; and

a shelf tier management system comprising:

a communication unit configured to communicate with the worker terminal;

at least one system memory storing an item information database, a shelf tier information database, and system program code; and

at least one system processor configured to access the item information database, the shelf tier information database, and the system program code and to operate as instructed by the system program code, the system program code including:

first acquisition code configured to cause at least one of the at least one system processor to acquire, from the shelf tier information database, size information of each of the plurality of shelf tiers;

second acquisition code configured to cause at least one of the at least one system processor to acquire, from at least one of the item information database and the shelf tier information database, size information of a respective accommodated item that is accommodated in each of the plurality of shelf tiers;

calculation code configured to cause at least one of the at least one system processor to obtain an occupancy rate of the respective accommodated item in each of the plurality of shelf tiers based on at least the size information of the respective shelf tier and the size information of the respective accommodated item, and to calculate a corrected occupancy rate for each of the plurality of the shelf tiers by correcting the respective occupancy rate with a correction coefficient according to the respective accommodated item;

first identifying code configured to cause at least one of the at least one processor to identify, based on the corrected occupancy rate of each of the plurality of shelf tiers, a recommended one or more shelf tiers, among the plurality of shelf tiers, to accommodate an unaccommodated item that is not yet accommodated in the plurality of shelf tiers, and

presentation code configured to cause at least one of the at least one system processor to cause the communication unit to transmit information regarding the recommended one or more shelf tiers to the worker terminal,

wherein the terminal program code comprises:

area map generation code configured to cause at least one of the at least one terminal processor to generate an area map comprising an installation position of each of the plurality of shelf tiers, the corrected occupancy rate for each of the plurality of shelf tiers, and the information regarding the recommended one or more shelf tiers, and

display code configured to cause at least one of the at least one terminal processor to display the area map on a display of the worker terminal.

2. The shelf storage management system of claim 1 , wherein the calculation code causes the at least one processor to calculate the corrected occupancy rate in a case where the occupancy rate is equal to or greater than a threshold.

3. The shelf storage management system of claim 1 ,

wherein the presentation code is further configured to cause at least one of the at least one system processor to cause the communication unit to transmit the occupancy rate of each of the plurality of shelf tiers to the worker terminal, and

wherein the area map further comprises both the occupancy rate and the corrected occupancy rate for one or more of the plurality of shelf tiers.

4. The shelf storage management system of claim 1 ,

wherein the item information database comprises one or more of an item category or an item attribute of the accommodated item of each respective accommodated item, and

wherein the calculation code is further configured to cause at least one of the at least one system processor to select each respective correction coefficient based on an item category or an item attribute of the respective accommodated item, and to correct each respective occupancy rate with the respective selected correction coefficient.

5. The shelf storage management system of claim 1 , wherein the first identifying code is further configured to cause at least one of the at least one system processor to determine whether the unaccommodated item falls under a shelf store-in prohibition condition associated with any of the plurality of shelf tiers based on item information related to the unaccommodated item obtained from the item information database, and to identify the recommended one or more shelf tiers by excluding a shelf tier among the plurality of shelf tiers for which the unaccommodated item is determined to fall under the shelf store-in prohibition condition.

6. The shelf storage management system of claim 1 ,

wherein the shelf tier information database comprises item turnover rate information including shipping records for items accommodated on the plurality of shelf tiers, and

wherein the first identifying code is further configured to cause at least one of the at least one system processor to identify the recommended one or more shelf tiers based on the corrected occupancy rates for the plurality of shelf tiers and the item turnover rate information.
