An environment history acquired from the environment in a container during transport of an article, ascertain a transport status including a transport route and the article, and execute quality control of the article in real time. An article management server memorized location data and a device code received from a GPS receiver in a second memory unit in association with each other, memorizes temperature data received from a delivery unit regularly and/or irregularly in a third memory unit associated with a unit number respectively, and memorizes a unit number and a serial number of an article in a fourth memory unit in association with each other. A transport-status-data generation unit uses a set of a certain unit number and a device code as a key, to generate transport status data representing a serial number, location data, and temperature data of the article during transport, based on the location data acquired from the second memory unit corresponding to the device code.
