Use the spreadsheet template in Table 7.9 to simulate a customer service desk with two servers. The start time of the process is 9:00 AM (cell C4), and the interarrival times (cells B5 to B14) are given in minutes. Assume that the process consists of a single queue oper- ating under a first-in-first-out discipline. That is, customers join the queue and move to the first available customer service representative in the order in which they arrived. Calculate the average waiting time and the utilization of each server.
