9780073401317 Simulation with Arena (6^th Edition), chapter 3, Q19, A two-workstation system processes two different kinds of parts. Parts of type 1 arrive according to an exponential interarrival time distribution with mean of 5.5 (all times in minutes) and go to get processed at workstation 1 the 2. Each workstation has one server. The type 2 parts arrive in exponential distribution with mean 9 and only go to workstation 2. Both parts have initial arrival time at 0 and both follow FIFO oreder when waiting. At workstation 2 both parts have the same priority. The processing time at workstation 1 has a triangular distribution with min. 2, mode 5 and max. 9. At workstation 2 the processing time has a uniform distribution between 1 and 5.
