This simple model demonstrates how to use SeizeTransporter, MoveByTransporter and ReleaseTransporter flowchart blocks when the transporter loading and unloading processes are complex. In this model, the SeizeTransporter block causes an AGV to go to a heavy paper reel and wait aside while a special crane loads the reel onto the top of the AGV. After, the MoveByTrasporter block causes the AGV to transport the reel to a conveyor. Once the AGV reaches its destination point, it is not released immediately but waits until it is unloaded by an unloading crane. The releaseTransporter block is used to release AGV after this process is completed. The processes of loading and unloading are represented using Process Modelling Library blocks that interact with Material Handling library blocks to simulate the moving processes of AGVs.
