The data below represent a simple single-server queue for a registration desk of a clinic. Patients show up at the arrival times, and require service times that are given in the table below. All times are in minutes and the queue discipline is first-in, first-out (FIFO). The simulation will just end at time 8, even if patients are in queue or in service at that time. Patient 1 2 3 4 Arrival Time Service Time 0 2 3 5 4 2 7 3 Compute the following output, and clearly explain the formulas and the logic you used to compute your output. Clearly explain the steps details and state your units. a) The average utilization of the registration staff, responsible for registering the patients (proportion or percent of time busy) b) The average of the patient total time in system. c) The average of the patient time in queue. d) The average number of patients in system. e) The average number of patients in queue.
