QUALITY CONTROL DEVICE, QUALITY CONTROL SYSTEM, QUALITY CONTROL METHOD, AND QUALITY CONTROL PROGRAM

摘要

An actual supply data acquirer acquires, for a replaceable member with which a product is replaceably provided, actual supply data representing an actual result of shipment for replacement of the replaceable member in the product that is already sold and used. A determiner, using the actual supply data acquired by the actual supply data acquirer, determines whether an excess demand situation occurs in which demand for the replaceable member exceeds predetermined forecasted demand. A notification controller, when the determiner determines that the excess demand situation occurs, performs notification control to cause sending of notification indicating a possibility that an abnormality is occurring in quality of the product.
