Suppose that you are using the four-period weighted moving average forecasting method to forecast sales and you know that sales will bedecreasing every period for the foreseeable future. What of the following would be the best set of weights to use (listed in order from the most recentperiod to four periods ago, respectively)?OA. 0.25, 0.25, 0.25, 0.25B. 0.10, 0.20, 0.30, 0.40C. 1.00, 0.00, 0.00, 0.00OD. 0.40, 0.30, 0.20, 0.10OE. 0.00, 0.00, 0.00, 1.00A Activity D on a CPM network has predecessors B and C, and has successor F. D has duration 6. B's earliest finish is 18, while C's is 20. F's late startis 26. Which of the following is definitely true?OA. B is a critical activity.OB. D is critical, and has a slack of two days.OC. C is completed before B.OD. F is critical, and has zero slack.OE. D has no slack but is not critical.

Activity D on a CPM network has predecessors B and C, and has successor F. D has duration 6. B's earliest finish is 18, while C's is 20. F's late startis 26. Which of the following is definitely true? A. D is critical, and has a slack of two days. O B. B is a critical activity. O C. C is completed before B. O D. F is critical, and has zero slack. O E. D has no slack but is not critical.
If an activity has a zero slack, it: A. Is on the critical path.B. Must be a noncritical activity.C. Can be completed in no time at allD. Means the project is expected to be delayed.

2:30 PM ě 4G+ 0.6KB/s l 54 00:15:19 Remaining Multiple Choice PERT is different from CPM in 'that unlike CPM, PERT is a network technique PERT uses probabilities on the activity times, whereas CPM uses deterministic time and cost estimates. PERT considers crash efforts and costs, while CPM does not PERT may be thought of as a mere subset of CPM. 12 of 20
A Gantt chart is a project schedule that superimposes project activities on a time line. Part 2 True False
Discuss the suggestion of preparing short-interval schedules 1 week prior to discussing them at a project meeting in order for all personnel to have ample time to review the information.
For the network schedule shown below, which statement is true? a. This is an example of the Activity-on-Node (AON) method of network diagramming.b. Activity F can start without waiting for the completion of Activity B.c. Activity B can occur concurrently with Activity D.d. To simplify the network, Activities F and G can be combined without changing the logic.
Activity Q on a project has exactly 4 successors E, F, G, and H whose late start days are 20, 12, 38, and 32. (Here "day" means days after project start and successor in this context means that E, F, G, and H are all dependent on Q.) What is the late finish day of Q?
. True/False Statements (Tick the correct option)  Selection of the critical path in network activity diagram for any project, is always focused onresult of the minimum time duration of the critical activities [ True / False ] Suppose, we have total 03 activities in the project “X”; namely L, M and N respectively. An activity “M” is the immediate successor of the activity “L”, while the activity “M” is the immediate predecessor for the activity “N”. According to this scenario, an activity “M” will be the last activity of the project “X” in the network activity diagram [True / False ] The dummy activity consumes both time and resources [True / False ] Towards the optimal solution through stepping stone method, when degeneracy problem is occurred, the next step is to focus on searching lowest value on the independent position in a non-allocated cells [True / False ] Hungarian algorithm, first convert any given assignment matrix into row reduction matrix [True / False

The extent of time by which an activity can be delayed beyond its earliest start time without extending the project is_____ Oa. Slack time O b. Latest start time Oc Optimistic time Od. Expected start time
What is the relationship between the earliest start time (EST) of an activity and the earliest completion time (ECT) of the activity? a. EST + Activity time = ECT b. EST × Activity time = ECTc. EST = ECT d. None of these statements is correct.
