Operator allocation in FlexSim

Description：

In the original state, the three operators(op1,op2,op3) are transferring items from Buffer10 to Process11,12,13. Once the content of Buffer10 is empty, than they will come to Buffer20 to help op4 to transferring items.

How to realize this simulation in FlexSim?

Software Version:

FlexSim 7.5.4

You can connect the operators 1,2,3 to your Dispatcher02 additionally. Because the operators 1,2,3 are connected to Dipatcher01 by their first input port they will receive always their tasksequence by this dispatcher first. If there isn't anything to do at this dispatcher they receive tasksequences by the other dispatcher.

I have tried it according to your advice, but the op1,2,3 work in buffer10 and buffer20 randomly.

I need them firstly finish the total work in buffer10, after that they come to buffer20.

I think there maybe need some priorities settings. would you pls. tell me how to do that? tks a lot.

They execute tasksequences as they occur in your model. The model work straighter if the dispatchers collect the tasksequences first, perhaps some seconds. You can delay the availability of the operator by closing their input.

If their are larger time gaps, when the operators 1,2,3 have nothing to do, but should be only available for dispatcher01, you have to give them something to do. You can give them utilize tasks and you free the operators, if there are tasksequences in the tasksequence queue of the dispatcher.

It is really difficult to assist from pictures alone.
