Delivery Management System, Delivery Management Method, And Program

A delivery management system comprising a delivery unit for delivering a container in which an accommodated article is cooled by a refrigerant, and an article management server that communicates with the delivery unit during transport via a communication network, wherein

• the delivery unit includes
• a GPS receiver that receives each GPS signal from a plurality of GPS satellites to calculate location data of the delivery unit based on each of the GPS signals, adds a unique device code to the location data, and transmits the location data to the article management server,
• a temperature measurement unit that measures a temperature in the container,
• a first memory unit that memorizes therein temperature data measured by the temperature measurement unit in a time series, and
• a first transmission unit that adds a unit number of the delivery unit to temperature data acquired from the first memory unit and transmits the temperature data regularly and/or irregularly to the article management server via the communication network, and
• the article management server includes
• a second memory unit that memorizes therein the location data and the device code received from the GPS receiver in association with each other,
• a third memory unit that memorizes therein the temperature data received from the delivery unit regularly and/or irregularly associated with each unit number,
• a fourth memory unit that memorizes therein the unit number and a serial number of the article in association with each other, and
• a transport-status-data generation unit that generates transport status data representing a serial number, location data, and temperature data of the article during transport based on location data acquired from the second memory unit corresponding to the device code, temperature data acquired from the third memory unit corresponding to the unit number, and serial number acquired from the fourth memory unit corresponding to the unit number, by using a set of a certain unit number and a device code as a key.
