The trace server 10 determines the credibility of a commodity distribution history by information from a managed temperature sensor 30 and the information from the facility temperature measurement devices 41, 42 and 43, obtains the temperature information to be used so that the determination accuracy is improved when determining, and manages the credibility of the commodity distribution history. With this configuration, a current configuration enables commodity distribution history management without adding special hardware. <P>COPYRIGHT: (C)2012,JPO&INPIT |
