Abstract: A sensor device for detecting product quality conditions is attached to each product to be delivered, and constant monitoring is performed on quality conditions of stock products in a storage room of a delivery center for quality assurance. For products in a storage room of a delivery truck, constant monitoring is also performed on quality conditions thereof in the same manner. If a quality abnormality is found in a product in the storage room, information regarding product sensing items and information regarding the current location of each delivery truck are processed to select a replacement stock product less susceptible to recurrence of a similar quality abnormality at the time of redelivery.

Abstract: An IC tag issue management system includes an ID numbering DB which stores an ID and a status of the ID, and an ID history DB which stores the ID, a history number indicating a reuse history of the ID, and a usage history indicated by the history number correlated with each other with each other. The IC tag issue management system numbers the ID with the usage history having a time elapsing from a starting date of the usage history in which the end date is not stored in the ID history DB passing over a predetermined ID-non-reusable period in response to a request for numbering the ID to be written into the IC tag when the unnumbered ID which has not been allocated to the IC tag, and the ID having the status of the ID numbering DB set in the “unused” status do not exist.
