An article transport apparatus has a path that has a first end and a
second end and that extends along a plurality of article transferring
locations, a plurality of article transporting vehicles that run on the
path, and control means for controlling the plurality of article
transporting vehicles. When the transport request data currently
processed and the transport request data previously processed specify a
same article transferring location for collecting, and the article
transporting vehicle that was selected based on the transport request
data previously processed is currently performing a transport operation,
then the control means selects an article transporting vehicle that is
not currently performing a transport operation as the article
transporting vehicle for a transport operation.
