<p>PROBLEM TO BE SOLVED: To certainly reduce shipping waiting time without disturbing a user. SOLUTION: When it approaches to a time frame having high shipping possibility for each contract user and a vehicle just before shipping is not stored in a storing shelf within a predetermined distance, a control device outputs a placement changing command to a conveying truck during an empty period when there is no storing or shipping vehicle and no vehicle waiting for storing or shipping. Thus, based on the placement changing command from the control device, a conveying truck transfers the vehicle just before shipping that is not stored in the storing shelf within the predetermined distance from a shipping opening to a storing shelf near the shipping opening to prepare for the shipping.</p> |
