Claims5
A transportation system comprising:
- a plurality of transport vehicles;
- and
- a controller configured or programmed to assign a transportation command to the transport vehicles;
- wherein
- the controller is configured or programmed to execute specific assignment processing to preferentially assign the transportation command having a relatively short transportation time or transportation distance to the transport vehicles;
- and
- the controller is configured or programmed to execute the specific assignment processing under a condition that an operating rate of the transport vehicles, which corresponds to a ratio of a number of the transport vehicles collecting or transporting an article to a total number of the transport vehicles in the transportation system, is equal to or greater than a threshold, and to then cause a selected transport vehicle, from among the transport vehicles, to transport based on the specific assignment processing.

A transportation control method for, in a transportation system including a plurality of transport vehicles, the transportation control method comprising:
- assigning a transportation command to the transport vehicles including preferentially assigning the transportation command having a relatively short transportation time or transportation distance to the transport vehicles;
- executing a specific assignment process under a condition that an operating rate of the transport vehicles, which corresponds to a ratio of a number of the transport vehicles collecting or transporting an article to a total number of the transport vehicles in the transportation system, is equal to or greater than a threshold;
- and
- causing a selected transport vehicle, from among the transport vehicles, to transport based on the specific assignment process.
