writing a transport task not on transport location

Hi FlexSim community

I´m still quite new to flexsim and i´m trying to do the following thing:

A dispatcher should get a message every week on which it creates a tasksequence for an operator.
This works fine so far.

The operator should travel to a specific queue, load an item and bring it to another specific queue.

What the operator actually does is getting the fixed ressource that created the initial message and drags it to the items assigned destination.

I assume that this is linked to the item declaration?
I just copy/pasted treenode item = parnode(1); into the dispatchers OnMessage trigger to get the load-task to work.
but i have no clue what this actually does and unfortunately the manual doesn´t help me either.


FS Version 7.3
The FR involved of the Model attached are "Dispatcher" and "Wochenticker"
both on the far right side.

Thanks for your help
Best regards
Philip

Hi Philipp,
parnode(1) is a referrence to the message sending object named "Wochenticker". The message does not contain any reference to the item. You can set a pointer to the first item of a queue by the command first(node("/Fertigwarenlager 1",model())).

treenode item = first(node("/Fertigwarenlager 1",model()));

Similar is the command last(obj.) wherein obj is a referrence to the container object.
Another possible command is the function rank(obj,order num). Order num is the number of the order of items stored in the queue, e.g. 1 = first, 2 = second and so on.

I will try that.

That will surely help me to get into it.
