Simulation Problems: Operator (and Tokens) strange behavior

Hello everyone,

The problem is related to the right side of the simulation. The different flowitems arrive at the end of the conveyor2 and from that point, Ana would have to take the different items and place them in the Queues depending on the type.

In order to doing that, I thought that a "Wait for Event (Conveyor2: On Exit)" would be OK, but since the flowitem does not leave conveyor, Ana does not move. I tryed to fix it adding an "Wait for Event (Conveyor2: On Entry) + Delay. At the beggining it worked, but I find some strange behaviour as the simulation continues (some tokens "jump" the wait for event). Could anyone help me?

Thanks in advance.

Hi @José Ignacio MN,

I think the problem you're describing is that the tokens each reference a specific item. For example, token 1 references item 1, token 2 references item 2, etc. Then, if both tokens are waiting for the trigger, item 1 triggers the Wait for Event, but token 1 AND token 2 leave that activity. Is that what you mean by jump?

If this is the case, you can use the label matching settings to make sure that the item that arrived matches the token that is released in the Process Flow activity. That way, if item 1 arrives on the conveyor, then only token 1 is released. NOT token 2. Have you tried this before? The settings can be found as shown here:

Hopefully I understood your concern correctly. Let us know if you're looking for something different.

OK got it! The problem was exactly what you said: both token 1 and 2 left the activity. Fix it thanks to your indications. Thank you!
