In the model database 333, an entry / exit plan ID 341, an environment model ID 342, and an environment model 343 are set.
In FIG. 14, for one entry / exit plan ID: A, the environmental model: Aa in the state where the dock shelter is opened, and the environmental model: A— in the state where the rearrangement of the luggage is completed and the dock shelter is closed. Two environmental models with b are added to the model database 333. More specifically, the environmental model ID 342 is an entry / exit plan ID + branch number.

In step S604, the model update unit 360 determines whether an input / output plan update notification from the input / output server 200a or an environmental model update request from the state monitoring unit 370 has been received. If an update notification or an environmental model update request is received, the process returns to step 603. In step S <b> 603, the model update unit 360 creates or updates an environment model for each entry / exit plan ID based on an update notification or an environment model update request. If neither an update notification nor an environmental model update request has been received, step S604 is repeated.
As described above, the model database 333 is updated by using a receipt notification of an entry / exit plan from the entry / exit server 200a or an environment model update request from the state monitoring unit 370 described later as a trigger.

Specifically, it is assumed that the entry / exit start notification 23 represents the entry start of the entry / exit plan A. That is, the environmental model ID is Aa.
In step S802, the method extraction unit 320a searches for the corresponding air conditioning method from the air conditioning method database 330a based on the entry / exit start notification 23. Specifically, the air conditioning method corresponding to the environmental model ID “Aa” is extracted.
In step S803, the method extraction unit 320a transmits a control instruction 21 that instructs the control unit 102a of the warehouse system to execute the extracted air conditioning method.
In step S804, the method extraction unit 320a determines whether an update notification of the currently executed air conditioning method has been received from the air conditioning method database 330a. If an air conditioning update notification is received, the process proceeds to step S805. If no air conditioning update notification has been received, the process returns to step S801.
In step S805, the method extraction unit 320a re-searches the air conditioning method from the air conditioning method database 330a. The method extraction unit 320a transmits a control instruction 21 that instructs the control unit 102a of the warehouse system to execute the re-searched air conditioning method.
