In analyzing the problem, think about this as a single-channel, single-phase system with Poisson arrivals and exponential service times.

Questions

a. Calculate the average customer arrival rate and service rate per hour.

b. Calculate the probability of zero patients in the system (PO), the probability of one patient (P I), and the probability of two or more patients simultaneously arriving during the night shift.

c. Using a criterion that if the probability is greater than 1 percent, a backup OR team should be employed, make a recommendation to hospital administration.
