Question: Consider an infinite capacity 3-machine 2-operator service system where an operator is required to setup a job on a machine before processing can begin. Develop the node-arc diagram for 5 or less jobs in the system. That is, develop the diagram explicitly for 0 to 5 jobs in the system with the understanding that the complete diagram would contain an infinite number of nodes. All processes, (arrivals, setups and processing) are assumed to be exponentially distributed with mean rates λ, γ, and μ, respectively.
