<p><P>PROBLEM TO BE SOLVED: To provide an automatic guided vehicle which automatically determines a conveyance path, and selects a proper path even when congestion prediction fails, without monitoring the detailed position and passing time of the conveyance device, without requiring a sensor, a communication path, nor a calculating device therefor, and without requiring highly accurate prediction, and to provide a conveyance path determination method. <P>SOLUTION: A storage device 17 stores a graph 1 in which a transfer point, branch point, merge point, conveyance source and conveyance destination of the conveyance device 11 are defined as "points" 2, a route from each point to an adjacent point to which the conveyance device 11 can directly travel is defined as a "branch" 3, and the load of each branch is defined as "weight" 4. A conveyance control device 18 determines a path in which the total weight of respective branches constituting a conveyance path from a conveyance source to a conveyance destination is minimum as a "scheduled route" for each object, adds predetermined weight to the current weight 4 of each branch of the determined scheduled route, separately controls the conveyance device along the determined scheduled route to convey each object, and subtracts the predetermined weight from the current weight of each branch of the scheduled route used for the conveyance. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
