select operator move the item to empty pallet

Hello my friends ! i want to use PF to implement a logic:

1. when Separator split an item into three items , pull a operator from list where operator's area label equal to output' area label .after a while,operator will move the item to empty pallet around(one pallet with one item);

2.AGV move the pallet to Sink,and a new empty pallet create in the queue.

In my model, operator's token in the process flow could not continue,now i don't know how to solve this probelm, why the token stopped.

Can someone help solve it? Thanks a lot!

When you create a task sequence, in order to add tasks to that sequence the subsequent activities need to reference the label where the task sequence is stored, not the task executer it belongs to.

Refering to the operator itself in the travel activity (or other task activities) essentially creates its own task sequence with only a single task in it. This task sequence will be put into the task sequence queue of the operator.

When creating a task sequence with Create TS, the operator will wait for new tasks to be added until that sequence is finished and can't start a new sequence in the meantime (unless through preemption).

And now that I have typed all this out I see that you have actually done this correctly for the second task sequence for the TE, so you might have just forgotten to change the activities after adding the Create TS and Finish TS activities.

One more thing though: The queue should probably only be pushed back to the list after the TE has loaded the pallet, since that is the point in time when a new pallet is created.
