Let the arrival rate to each station be λ/ 2 and the service rate of each server be μ . We now pool two stations together and thus form an M/M/ 2 queueing system with one waiting line. The arrival rate to the pooled system is therefore, λ , and the service rate of each server is μ . Assuming λ < 2 μ , compare N and N q for these two systems. 2. Consider a production system consisting of three single-server stations in series. Customer orders arrive at the system according to a Poisson process with rate 1 per hour. Each customer order immediate triggers a job that is released to the production system to be processed at station 1 first, and then at station 2. After being processed at station 2, a job has p 1 = 10% probability going back to station 1 for rework and 1- p 1 probability continuing onto station 3. After being processed at station 3, a job has3....
