Question

The following data yield the arrival times and service times that each customer will require for the first 13 customers at a single server system. Upon arrival, a customer either enters service if the server is free or joins the waiting line. When the server completes work on a customer, the next one in line (i.e., the one who has been waiting the longest) enters service. A) Determine the departure times of these 13 customers. B) Repeat part (a) when there are two servers, and a customer can be served by either one. C) Repeat part (a) under the new assumption that when the server completes a service, the next customer to enter service is the one who has been waiting the least time. Arrival Times: 12 31 63 95 154 198 221 304 346 411 455 537 Service Times: 40 32 55 48 50 47 18 38 54 40 72 12
