Bill Youngdahl has been collecting data at the TU student grill. He has found that, between 5:00 P.M. and 7:00 P.M., students arrive at the grill at a rate of 25 per hour (Poisson distributed) and service time takes an average of 2 minutes (negative exponential distribution). There is only 1 server, who can work on only 1 order at a time. a. What is the average number of students in line? b. What is the average time a student is in the grill area? c. Suppose that a second server can be added to team up with the first (and, in effect, act as 1 faster server). This would reduce the average service time to 90 seconds. How would this affect the average time a student is in the grill area? d. Suppose a second server is added and the 2 servers act independently, with each taking an average of 2 minutes. What would be the average time a student is in the system?

Student arrival time range – 5:00 – 7:00
Rate of student – 25 per hr
Average service time – 2 min
Number of order handle at time – 1
What is the average number of students in line?
Average number of student in line is zero
b. What is the average time a student is in the grill area?
Average turnaround time is 2 min
c. Suppose that a second server can be added to team up with the first (and, in effect, act as 1 faster server). This would reduce the average service time to 90 seconds. How would this affect the average time a student is in the grill area?
Average time will not change as there is no waiting time and only serving time. So average time will remain 2 min
d. Suppose a second server is added and the 2 servers act independently, with each taking an average of 2 minutes. What would be the average time a student is in the system?
Average time will not change as there is no waiting time and only serving time. So average time will remain 2 min

They want to set up an assembly line to make their operation more efficient and plan to use line balancing with the longest-task-time heuristic. The demand for power supplies is 70 per hour, and the productive time per hour is 52 minutes. The following table provides details on their operation.

  4. Many of a bank’s customers use its automatic teller machine to transact business after normal banking hours. During the early evening hours in the summer months, customers arrive at a certain location at the rate of one every other minute. This can be modeled using a Poisson distribution. Each customer spends an average of 86 seconds completing his or her transactions. Transaction time is exponentially distributed. a. Determine the average time customers spend at the machine, including waiting in line and completing transactions. (Do not round intermediate calculations. Round your answer to the nearest whole number.) Average time minutes b. Determine the probability that a customer will not have to wait upon arriving at the automatic teller machine.
