Abstract: An automatic traveling system includes a management server and an AGV, and the management server controls the AGV. When there is a transport request, the management server determines an available AGV, determines a traveling route from a standby position to a loading position, determines a traveling parameter table corresponding to the traveling route, and transmits a traveling instruction including the traveling route and the traveling parameter table to the target AGV. The AGV travels along the traveling route by using a traveling parameter corresponding to the load of a cargo and the traveling velocity. The AGV also travels from the loading position to a transport destination and then from the transport destination to the standby position. For each traveling route, the traveling route and the corresponding traveling parameter table are transmitted to the target AGV.

Abstract: An automatic vehicle dispatching system is applied to a factory where manufacturing operation devices reside, and includes an optimization server, a management server, and AGVs. The management server controls transfer of the AGVs and transmits a current transport request received from one of the manufacturing operation devices to the optimization server. The optimization server predicts a future transport request to be issued by each of other manufacturing operation devices using predicted transport request interval patterns, and generates allocation models by allocating AGVs to each transport request in different patterns. The optimization server predicts required transfer times for the allocated AGVs and adds up the required transfer times for each allocation model.
