How to give working priority to an operator ?

I'm new on flexsim and I lack knowledge

I have three same production lines with one operator. Each source have a flow of 14 seconds. I want that my "BAC" will never be full (50 parts). I also want that my operator empties one " BAC" before working on an other one.

-the operator leaves his "BAC" when it is empty

-the operator leaves his "BAC" when another is full

The objective is to minimize the travel time between the production line.

Thank you for your help

Does your model show one "BAC" or all three? Is there one Operator for all lines? There are only Queues in your model, so I assume you didn´t implement the production lines!?

Your model further throws exceptions, because in your receiving Queues you´ve turned on the "Use Transport" option and said that "Centerobject 1" should do the job, but you didn´t connect any centerobjects!?

So for me it is hard to figure out how good your knowledge about FlexSim is.

I´m sure there are at least 2 ways to do what you are looking for:

1. could be to open and close ports of objects depending on there filling level and use the Priority fields of the created task sequences.

2. could be to use Process Flow to make your operator exactly what you want, whenever you want.

What do you prefer?

@Romain C

Here is an example model with the use of Process Flow. The operator will rotate between the different production lines to move all items from the BAC to the right palette and then moving on to the next BAC. I am still working on commanding the Operator to leave once a BAC is full.

@Romain C

I was able to fix the problem of having the operator move to a different BAC once it is full. This was done by adding Custom Code.
