In a transfer system, at least one of a plurality of process apparatuses is connected to a station as a connected process apparatus. A station control unit controls a transfer device provided in the station through a communication with a process apparatus control unit to load the processing object to the connected process apparatus from the station and to unload the processing object from the connected process apparatus to the station. The station control unit controls the transfer device to begin unloading of the processing object from the connected process apparatus to the station after receiving a signal indicative of a presence of the processing object to be unloaded from the process apparatus control unit.

Transfer system

A process-line-to-process-line transport apparatus transports a transport subject between corresponding two of process lines. A first transport vehicle transports the transport subject in a first process line, and a second transport vehicle transports the transport subject in a second process line. A relay stocking apparatus is placed in a corresponding location, at which the relay stocking apparatus receives the transport subject from one of the first transport vehicle and the second transport vehicle and passes the received transport subject to the other one of the first transport vehicle and the second transport vehicle.

Transport system

In a transfer system, a storage data and a specific equipment data indicating a specific equipment are generated. When a transfer command indicates the specific equipment as one of a previous location and a subsequent location, a priority level of the transfer command is increased. A transfer command having a highest priority level is selected. When an available carrier that is not assigned with a transfer command is not accessible within a previous area in which the previous location of the transfer command selected belongs to, when the priority level of the transfer command selected has been increased, and when an alternative carrier that is assigned with the transfer command and is transferring without carrying the cassette is accessible within the previous area, the transfer command selected is assigned to the alternative carrier.
