MoveByTransporter

It is the block that performs transportation of an agent by a transporter. You define a fleet of transporters of a certain type using the TransporterFleet block. An example of a transporter is an AGV (automated guided vehicle). Transporters move along network paths. By default transporters take the shortest route. If needed, you can manage the routing by yourself by providing the path selection algorithm in the corresponding TransporterFleet block.

The MoveByTransporter block provides a complete set of parameters for seizing a transporter, loading it with the required agent, sending it to the specified location, unloading the agent there, and finally releasing the transporter.

Seizing and releasing actions can be modeled by the corresponding SeizeTransporter and ReleaseTransporter blocks (use them to design a more detailed agent transportation flowchart). In this case, make sure to disable the Seize transporter and Release transporter parameters of this MoveByTransporter block.

Once the transporter is seized and sent to fetch the agent (material item) it will choose the shortest path to the specified destination. If the required destination is not in the network, the transporter will come as close as it can to it.
