I have a "priority" question

I have two items(red and green). A red item is important, so it is the highest priority lot.
It have to be transferred in time.
How can I do? Thank you.

Hi Li,

As you might or might not know, the transport of the products between the machines is done by creating a tasksequence for the forklift truck. So if you want that a forklift truck picks up a product before another product, you have to set the priority of the tasksequence. that can be done with the "priority" box of the output part of the "flow" tab page.

But in your case you want that to be dynamic based on the product entering the processor, so what you can do is set the priority when the product enters. Your code should look like:

setvarnum( current, "transportpriority", 2 - getitemtype(item));

In this code "current" points to the processer itself
"transportpriority" is the name of the variable that stores the priority of the tasksequence that is being generated.
and because in your case the red products are itemtype 1 and the green are itemtype 2 I used the 2 - getitemtype because the higher the number the higher the priority.

I tried the method, but I defeated. I don't know the "code" how to do?
Maybe I should detailed answer!
Help me!! Thank you.

Li,

I can't post your model back because you are working with an old version that needs compiling. So please upgrade your Flexsim and I can post a model.

For now, simply copy the statement I gave you on the "onentry" trigger of every processor. That should do the trick.

Dear sir

Thanks for your model.But now I have a problem.
The red items is higher priority, so transporters to carry before the green items.
The question is:

If a red item has finished by a processor currently and a forklift truck is ready to pick up a green items(transfer yet), the forklift truck have to change its goal. That is transfer reditem before green. But the model can't do. I can't do it, so I need help. Is it possible to do it?

Best Regards
