Abstract: Article transport vehicles have, as operation states, a first state of traveling toward a transport destination that is a destination set for receiving an article or delivering an article, and a second state in which a transport destination has not been set. A controller divides the entirety of a travelable route into a plurality of set areas and executes imbalance reduction control to arrange standby transport vehicles such that imbalance of the densities of standby transport vehicles present in the areas is within a predetermined range, the standby transport vehicles being article transport vehicles in the second state.

Abstract: A reference cost and a variable cost are included in a link cost for setting a set route for causing a setting vehicle to travel to a destination on a travelable route. A controller obtains an adjusted variable cost by adjusting a variable cost using a priority adjustment value set higher as a priority for arriving more quickly at a destination decreases, determines a link cost for each link in a candidate route, which is a candidate for a set route for a setting vehicle, based on the adjusted variable cost and the reference cost, obtains a route cost for each candidate route based on the link costs, and sets the set route based on the route costs of the candidate routes.

Abstract: A reference cost and a variable cost are included in a link cost for setting a set route for causing a setting vehicle to travel to a destination on a travelable route. A controller obtains an adjusted other vehicle cost by adjusting another vehicle cost with use of a separation adjustment value set smaller the higher a separation index is, obtains a variable cost based on a sum of the adjusted other vehicle costs of all target other vehicles, determines a link cost for each link in a candidate route, which is a candidate for a set route for the setting vehicle, based on the variable cost and the reference cost, obtains a route cost for each candidate route based on the link costs, and sets a set route based on the route costs of the candidate routes.

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.
