do not repeat

i have been working on a model where objects come in to the simulation, three processors have been set up.As each object comes it goes to the first processor available, in order for the object to be finished it has to go through the three processors. how can i manage the objects to go through all the three processors regardless from where they started without repeating any processor? thxs

Please have a look in the download section, where I posted a model (Support_ThreeProcessesWithRandomStart_TD) for your little assignment.
I hope the model does what you want.

hey thank you very much, the model does what i need.

I found another way to do it,similar logic to yours, using labels but without having to write any code.

Yes, it is the same concept I was using (labels for information), but I like your solution. Putting in an additional queue makes it possible to just use the picklists. Good Job!
