Well days can you help me correct the model I have, what happens is that I have a model where 4 workers participate to go from the loading area to the exit 1,2 some boxes what I want is that they only load two operators per exit that The 4 operators do not act for a single output and it would be more or less like this, that is, there are 4 operators working while two operators load an output area the other two also do the same and another error that I do not want is that when they are loading in The waiting area is that the operators will agree if any of these areas is available, that is to say that they go in order and take as a priority that to load it depends on the waiting area that is filled. first, download it and so follow that sequence
