ABSTRACT:
In the case of transporting an article to a load port which is occupied by another article, at the time of generating a transportation command, estimated arrival time T1when the article arrives at the load port and estimated removal time T2when the article which occupies the load port is removed are compared with each other. If the time T2is earlier than the time T1, a transportation command for transporting the article to the load port is assigned. If the time t2is later than the time T1, a transportation command for transporting the article to a buffer on the upstream side of the load port is assigned.
