The concession stand at the baseball park gets (on average) 20 customers per inning. The cashier can process 30 customers per inning (on average). The concession manager does not understand how they can have any line at all when they are able to process the customers much faster than they arrive. Can you help explain to the manager the characteristics of their waiting line system? (In other words, CALCULATE the following: Ws, Wq, Ls, Lq, utilization and Po) (You believe this to be a M/M/1 system) (Reminder to state the queue discipline) (unit of time is "inning")
