The probability distributions for inter-arrival and service times for the help desk for a loan application center are given below. Assume that the first customer calls at time 9AM and that no one is being served or waiting to be served when the first customer calls. Simulate the arrival and service for 10 customers for one and two service representatives starting at 9AM. Determine the average customer waiting time for each of the two situations? The probability distributions for inter-arrival time and service time are given below. Write random numbers in the tables below. Use the table on the next page for simulating the one-representative case and the two-representative cases.
