Question 1.1. In a PERT network, the earliest (activity) start time is the (Points : 4) earliest time that an activity can be finished without delaying the entire project. latest time that an activity can be started without delaying the entire project. earliest time that an activity can start without violation of precedence requirements. latest time that an activity can be finished without delaying the entire project. None of the above Question 2.2. PERT and CPM are quantitative analysis tools designed to schedule and control large projects. (Points : 4) True False Question 3.3. The expected time in PERT is (Points : 4) a weighted average of the most optimistic time, most pessimistic time, and four times the most likely time. the modal time of a beta distribution. a simple average of the most optimistic, most likely, and most pessimistic times. the square root of the sum of the variances of the activities on the critical path. None of the above Question 4.4. On a practical note — if we are using waiting line analysis to study customers calling a telephone number for service, balking is probably not an issue. (Points : 4) True False Question 5.5. An arrival in a queue that reneges is one who (Points : 4) after joining the queue, becomes impatient and leaves. refuses to join the queue because it is too long. goes through the queue, but never returns. jumps from one queue to another, trying to get through as quickly as possible. None of the above Question 6.6. PERT was developed for a project for which activity or task times were uncertain. (Points : 4) True False Question 7.7. The following represents a project with four activities. All times are in weeks. Activity Immediate Predecessor Optimistic Time Most Likely Time Pessimistic Time A – 2 8 14 B – 8 8 8 C A 6 9 18 D B 5 11 17 According to the data in Table above, what is the minimum expected completion time for the project? (Points : 4) 18 19 37 11 None of the above Question 8.8. A suburban specialty restaurant has developed a single drive-thru window. Customers order, pay, and pick up their food at the same window. Arrivals follow a Poisson distribution while service times follow an exponential distribution. If the average number of arrivals is 6 per hour and the service rate is 2 every 15 minutes, what is the average number of customers waiting in line behind the person being served? (Points : 4) 0.50 0.75 2.25 3.00 None of the above Question 9.9. Given the following small project, the critical path is ________ days. (Points : 4) Activity Immediate Predecessor Time (days) A – 10 B – 4 C A, B 6 10 14 16 20 None of the above Question 10.10. The study of waiting lines is called queuing theory. (Points : 4) True False Question 11.11. Slack is the time an activity can be delayed without impacting the completion time of the project. (Points : 4) True False Question 12.12. CPM was developed for use in managing projects about which we have good information about activity or task completion times. (Points : 4) True False Question 13.13. In queuing analysis, total expected cost is the sum of expected ________ plus expected ________. (Points : 4) service costs, arrival costs facility costs, calling costs calling cost, inventory costs calling costs, waiting costs service costs, waiting costs Question 14.14. One of the most significant benefits of PERT is that it forces the project manager to sit down and plan the project in great detail—and thus come to an understanding of relationships between the activities. (Points : 4) True False Question 15.15. Given the following small project, the critical path is ________ days. Activity Immediate Predecessor Time (days) A – 8 B A 4 C – 10 (Points : 4) 4 10 12 22 None of the above Question 16.16. A bank with a single queue to move customers to several tellers is an example of a single-channel system. (Point
