Work management device, work management method, and program storage medium

A work management method performed by at least one processor, the work management method comprising:

• calculating, for each work section of a plurality of work sections divided from a whole region in a work range for relay-type picking work, work efficiency which is calculated, based on work history of work performed by working objects in the relay-type picking work, the relay-type picking work being one of a delivery work in a warehouse, an assembly process in a factory, loading and unloading of cargo at a harbor, and storage on and delivery from a truck;
• calculating or reading information about a duration time being a calculated value or a setting value for which a state is expected to continue, the state being a state where the work efficiency based on a work status of a working object among the working objects is the work efficiency calculated, in the work section;
• acquiring information about a cost being a loss incurred when the working object moves between the work sections;
• determining, based on an estimated work amount and the cost, arrangement of the working objects in the plurality of work sections in such a way as to increase work efficiency in the whole of the work range, the estimated work amount being estimated based on the work efficiency and being an amount of a work performed by the working object until the duration time is elapsed in the work section;
• outputting, to a work manager or the working objects, movement instructions based on the determined arrangement of the working objects;
• and implementing, by the at least one processor;
• a remaining work amount acquisition unit configured to calculate, based on a work amount remaining in the work section, and the work efficiency, an end time at which a work of the remaining work amount in the work section ends;
• a history information acquisition unit configured to acquire, as work history information, information about a work item and a number of works conducted in a most recent period set as an evaluation period;
• and
• an index determination unit configured to calculate, based on the work efficiency, the information about the duration time, and the information about the cost, a first future index depending on an estimated amount of a work performed by the working object until the duration time is elapsed for a case where the working object moves, calculate, based on the work efficiency and the information about the duration time, a second future index depending on an estimated amount of a work performed by the working object until the duration time is elapsed for a case where the working object does not move, and compare the first future index and the second future index.

A non-transitory computer readable storage medium recording thereon a program causing a computer to perform processes comprising:

• calculating, for each work section of a plurality of work sections divided from a whole region in a work range for relay-type picking work, work efficiency which is calculated, based on work history of work performed by working objects in the relay-type picking work, the relay-type picking work being one of a delivery work in a warehouse, an assembly process in a factory, loading and unloading of cargo at a harbor, and storage on and delivery from a truck;
• calculating or reading information about a duration time being a calculated value or a setting value for which a state is expected to continue, the state being a state where the work efficiency based on a work status of a working object among the working objects is the work efficiency calculated, in the work section;
• acquiring information about a cost being a loss incurred when the working object moves between the work sections;
• determining, based on an estimated work amount and the cost, arrangement of the working objects in the plurality of work sections in such a way as to increase work efficiency in the whole of the work range, the estimated work amount being estimated based on the work efficiency and being an amount of a work performed by the working object until the duration time is elapsed in the work section;
• outputting, to a work manager or the working objects, movement instructions based on the determined arrangement of the working objects;
• and
• implementing, by at least one processor of the computer;
• a remaining work amount acquisition unit configured to calculate, based on a work amount remaining in the work section, and the work efficiency, an end time at which a work of the remaining work amount in the work section ends;
• a history information acquisition unit configured to acquire, as work history information, information about a work item and a number of works conducted in a most recent period set as an evaluation period;
• and
• an index determination unit configured to calculate, based on the work efficiency, the information about the duration time, and the information about the cost, a first future index depending on an estimated amount of a work performed by the working object until the duration time is elapsed for a case where the working object moves, calculate, based on the work efficiency and the information about the duration time, a second future index depending on an estimated amount of a work performed by the working object until the duration time is elapsed for a case where the working object does not move, and compare the first future index and the second future index.
