Problem with wait for event

[ FlexSim 17.2.0 ]

I'm working on a logic and is working fine except for a little detail.

First, a tote is created and transported to a conveyor, where it travels to a Decision Point where it stops, is filled with a random number of items (duniform) and continues to the next point where the cycle repeats.

The cycle is finish when there is no more Decision Point. Until this all works fine.

There is a condition where if the box is filled beyond a certain number, the tote is placed in a second conveyor and the operator goes for another tote and continues in the next decision point. The problem here is that the tote stops one Decision Point before is supposed to, but the strange thing is that the reference for the decision point (called estacion) works fine, because the objects being picked are on the right rack.

Here is the model:

Are you on 17.2.1? There was a bug with the Wait for Event, that was fixed from 17.2.0.

It works for me in 17.2.1, Jordan is probably correct that it was a bug in 17.2.0. I did notice that you are getting totes from queue1 but it is sometimes empty which causes an invalid Load activity to happen. To fix this you just have to check the content of the queue and if it is empty use a Wait For Event to wait for a tote.

@Julio R

The model does seem to work in 17.2.1.
