How to prevent incoming and outgoing tote processed at same time

Hi in the attached model I tried to use triggers to prevent a box with a tote from processed at the same time (If a box with a tote is in "processor15" then AGV should not drop off in "separator7" and if AGV is on the way to drop off a part in "separator 7" then a box with tote should not enter "processor15" using triggers. But it is not working, couldsomeone help me to fix this issue?

FlexSim 22.1.4

You could try adding a process flow and using a zone with max content. You'd need to create a token for each flowitem that will go to the processor or separator, use a wait for event activity to wait for when the flowitem enters the processor or separator, and then enter the zone. Something similar to this:

Here's a tutorial you may find helpful about using process flow (including zones):

Can you suggest some other way without process flow?

The sample i attached is a part of large model and at this storage it is difficult to add the process flow and i just started learning process flow.

How are you with coding the creation and dispatch of task sequences that create and call subtasks and release taskexecuters from utilize tasks using freeoperators() ?

I expect process flows will be easier for you and will not be hard to implement in your larger model.

Hi Jason. I am not proficient with coding and it is ok if you guys cannot help me with this.

We can help with either the coding or the definition of a process flow - I think the process flow is going to be easier for you though.
