Operator not following the sequence and batch order on multiple machines

Hello, in my model 1 operator is working on 2 machines.

Operator's Process flow will be – Travel till Queue 5 – pick 2 parts – walk to queue 2 – place there – get 1 part out of it – walk till Processor 1 – process on it and pass to Queue 1 – walk back till Queue 2 – get second part – walk till Processor 1 – process on it – pick up the product – walk till Queue 1 – get first part also – walk till Queue 3 with 2 parts in hand – place on Queue 3 – walk till rack 1 - pick up one part - walk till Processor 2 – process the part - pick up the part - walk till queue 4 – after completing this repeat the same sequence

Thanks in advance.

For this you should probably create exactly that sequence of tasks in a process flow.

Years ago we would have used a tasksequence with callsubtasks but a process flow will be much easier.

Hello Jason, One thing I missed is the part receiving at Queue 5 is not continuous. I have corrected in the attached model. You can see after 140 seconds operator starts carrying the parts without finishing the task. sample 4.fsm

You can try to use the "Break To" setting of the operator and the preemption and priority settings for the different tasks to get the result you want to achieve.

Though as Jason said, a long sequence of tasks with a fixed would likely be easier to implement in Process Flow, since it gives you direct control of the order of operations.

Here is an example to get a stable sequence of processing support and transport.
