Warehousing and shipping operation support system, warehousing and shipping operation support method, and non-transitory computer-readable medium

A warehousing operation support system, the system comprising:

• a plurality of fixed communication units (40) configured to transmit pulse signals;
• a communication tag (10) configured to receive the pulse signals from the plurality of fixed communication units (40) and return the pulse signals to the plurality of fixed communication units (40);
• a scanner (30) configured to scan optical recognition codes that are attached to objects (L), wherein each optical recognition code is associated with first information on the respective object (L);
• a computer (50) comprising a processor (52), and a memory (53), wherein:
• the computer (50) is in wireless communication with the scanner (30),
• the computer (50) is in communication with the plurality of fixed communication units (40),
• the memory (53) stores a database (53b) that includes information on stored objects (L), the first information associated with the optical recognition codes, and information on storage spaces (C) of the stored object (L), and
• the computer (50) is programmed to:
• receive an indication that the optical recognition code attached to an object is scanned by the scanner (30),
• determine a location of the communication tag (10) at the time that the object is scanned by the scanner (30) based on a time taken for the communication tag (50) to receive the pulse signals from the plurality of fixed communication units (40) and return the pulse signals to the plurality of fixed communication units (40),
• determine if the location of the communication tag (10) is in a vicinity of an empty storage space (C) using the information on storage spaces of the stored object (L) stored in the database, and
• after determining that the location of the communication tag is in a vicinity of an empty storage space (C), modify the database to associate that storage space (C) with the first information associated with the optical recognition code of the object (L) scanned by the scanner (30) and with the information on that object (L).
