Product defective estimation methods and products defective estimation system

摘要

PROBLEM TO BE SOLVED: To estimate a transfer carriage in which a product failure in a warehouse occurs.;SOLUTION: A warehouse failure estimation system 1 includes a failure occurrence estimation device 10 and an in-vehicle terminal 20 attached to a baggage transfer machine 2. The in-vehicle terminal 20 acquires working data about baggage transfer and measurement data measuring a status of a transfer carriage to transmit the data to the failure occurrence estimation device 10, and receives failure candidate information in which a product failure may occur. When a working transfer carriage falls into the information, warning is notified. The failure occurrence estimation device 10 acquires the working data, measurement data, and failure result information showing the transfer carriage in which the failure may occur; determines a failure occurrence estimation threshold value concerning items showing the status of the transfer carriage correlated with failure occurrence; and writes the transfer carriage in which a value of the measurement data exceeds the failure occurrence estimation threshold value in the failure candidate information, and transmits it to the in-vehicle terminal 20.;COPYRIGHT: (C)2014,JPO&INPIT
