Attached is a simple model to help demonstrate something I would like to learn best practices for. Essentially an item gets processed and then 50% need to go to a secondary process. Items cannot move to the secondary process until they are finished with the first process. The problem I have with the model is that items will wait on Processor 1 and 2 (like an unintentional queue) at the end until Processor 3 and 4 are free, but Processor 1 and 2 will still function as normal. Ideally I want Processor 1 and 2 to be tied up until the secondary processors are free. Queue 2 would increase quantity and then I can increase processors in resource B or increase process time to make the system run smooth. Thoughts?Processor Back Up Example.fsm
