With the second area transport control, a partial path from a second transfer position of a target connecting transport facility to the destination point is set on the basis of transportation status information of the second area transport facility.

Abstract: An article transport facility includes article transport vehicles that travel along a specified travelable path, and a control device that controls the article transport vehicles. The travelable path includes nodes and links each connecting a pair of the nodes. The control device sets a setting path based on a link cost that is set for each of the links. The link cost includes a reference cost and a variable cost. The reference cost is a value that is set based on a reference passage time that is required for a target vehicle to pass through a target link in a state in which another vehicle is not present in the target link. The variable cost is a value that is set based on a vehicle count-related increased time by which an actual passage time is increased relative to the reference passage time according to the number of the other vehicles present in the target link, the actual passage time being a time required for the target vehicle to pass through the target link.
