Setup Priority problem

I'm working on a one man 4 machine problem.The operator is responsible for loading / unloading parts

Problem - Please take a look at the model.
when loading/unloading time of operator is 0 sec, operator is working that I want.
But When I change loading/unloading time to 4 sec, operator isn't working that I want.
Operator should do the next work after he finish the current work.
but when loading/unloading time is 4 sec, operator go to the next work before he doesn't finish current work.
I think that priority or preemtion is cause of this problem.

Can someone please help me fix the model?

You help is much appreciated!

Hi,

what is your intention to use the preempting value 3

3 - PREEMPT_AND_ABORT_ALL - If a task sequence has this value, then the TaskExecuter will stop the currently active task sequence, destroy it, and destroy all task sequences in its task sequence queue.

Manual: Task Sequences; Concept; Task Sequence Preempting.

You delete with it all task sequences which have been allready created and stored at your dispatcher. The Transfer of Products won't happen, for all the Products (items) your modell created task sequences so far.

How or in which order do you want to transfer the products?

You created a custom code in the separator. Therein you use "a" for a variable name. That might work here, but "a" has got a relation to special functions in the flexsim engine. The use is not advisable.
Here is another hint to you source code for the if-conditions in the separator at the flow end. Port 1 is the connection to the sink. For the Port 2 and 3 you set the return value to the reference towards the task executer. All this is correct.
You can shorten this:

/**Custom Code*/
treenode item = parnode(1);
treenode current = ownerobject(c);
int port = parval(2);
if(port>1)
return tonum(centerobject(current,1));
else {
    transportoutcomplete(current, item, port);
    transportincomplete(outobject(current, port), item, opipno(current, port));
    moveobject(item, outobject(current, port), port);
}
