Transport issues

Hello community,

i have a little bit trouble with a quite easy problem i think.

I have a queue. The queue is using three taskexecuter for transport (coordinated by a dispatcher).

By reaching a certain level of content, the transport is executed.

My idea is, that the first available is doing the whole transport. But the dispatcher seems to split it. The first Taskexecuter is leaving two items in the queue and the other two Taskexecuters are taking each one item.

What i'm doing wrong?

Hi,

You are not doing anything wrong, this is just how Flexsim works. When a dispatcher receives tasksequences it offers them to every task executer.

What you can do is create your own passto code. You could start with the option to send to the shortest queue and change that to the longest queue with an extra condition that it should not be more than the max content.

Hello Florian,

you aren't doing anything wrong! It is the standard method to dispatch tasksequences from the tasksequence queue. Everytime an item enters a fixed rescource the tasksequence is written and dispatched. They are being executed or they are stored at the dispatcher (in a taskexecuter itself or a dispatcher).
Loading more flowitems is controlled in the break to requirement function of the taskexecuter. Therefore the tasksequence is partly executed to the breaktask and this is the problem. The receiving taskexecuter isn't available anymore and the next queued tasksequence is dispatched to another available taskexecuter.
To let only one taskexecuter to work on more then one tasksequence the other available taskexecuter shouldn't be available for a certain time (or event steps). You can close the output to the other taskexecuters at the moment a tasksequence is dispatched until the maximum content of the first taskexecuter is reached.

maybe it helps.

Hi,

i was able to solve my task now. I just replaced the queue by a queue shaped combiner with a process time of 0.

The collecting time until 8 pallets are in the queue is the same. And because my Taskexecuters aren't able to overtake, i choosed "round robin" as passto code.

Thank you both for your input!
