Compute the slack time for activity C. 0 4 2 3 Question 2 A PERT/CPM activity has an optimistic time estimate of 3 days, a most likely time estimate of 8 days, and a pessimistic time estimate of 10 days. The expected time (in days) of this activity is: 7.0 7.5 Question 3 8.0 8.5 A PERT/CPM activity has an optimistic time estimate of 3 days, a most likely time estimate of 8 days, and a pessimistic time estimate of 10 days. The standard deviation of this activity is: 7/9 7/6 1/3 2/3 Question 4 A dummy activity in a PERT network allows us to specify the positive time and resources required to complete the activity. maintain the precedence relationships. add more starting nodes. add more ending nodes. Question 5 A dummy activity is used to show a precedence relationship, but it does not represent a relationship between activities. change in relationship. real activity. passage of time. Question 6 A list of the tasks, broken down into modules, components, and individual tasks, is called a work breakdown structure (WBS). PERT. planning matrix. critical path. Question 7 Consider the following project. What is the critical path? ACFG ADFG BEG ACDFG Question 8 Consider the following project. What is the latest finish time for activity F? 9 7 13 16 Question 9 Consider the following project. What is the latest possible time that Activity E can be started without delaying the completion of the project? 8 3 7 9 Question 10 Consider the following project. What is the latest time that activity B can finish without delaying any other activities? 0 8 9 4 Question 11 Consider the following project. What is the latest time that activity B can start without delaying the project? 0 8 4 7 Question 12 Consider the following project. What is the minimum possible time for completing this project? Question 13 15 days 16 days 18 days 20 days Consider the following project. Determine the critical path. ACEH BCEH BDFH BDGH Question 14 Consider the following project. Determine the estimated completion time of the project. 23 days 22 days 25 days 20 days Question 15 Consider the following project. Determine the slack for activity D. 2 days 4 days 6 days 5 days Question 16 Consider the following project. Determine the slack for activity F. Question 17 2 days 3 days 4 days 5 days Consider the following project. How much can activity F be delayed without delaying the project completion? 1 day 2 days 3 days 4 days Question 18 If an activity cannot be delayed without affecting the entire project the it is a critical activity. . completed critical crashed normal Question 19 If t is the expected completion time for a given activity, then: LF = LS - t EF = ES - t EF = ES + t EF = LS - t Question 20 The diagram below shows the activities on the nodes, and the table shows the normal time and crash time (in days) and cost for each activity. Activity Normal Time Crash Time Cost per day to crash A 6 6 --- B 10 8 $100 C 5 4 $300 D 4 1 $700 E 9 7 $500 F 2 1 $650 Determine which activities should be crashed to shorten the project by 1 day. B C D E Question 21 The diagram below shows the activities on the nodes, and the table shows the normal time and crash time (in days) and cost for each activity. Activity Normal Time Crash Time Cost per day to crash A 6 6 --- B 10 8 $100 C 5 4 $300 D 4 1 $700 E 9 7 $500 F 2 1 $650 Determine which activities should be crashed to shorten the project by 2 days. Crash activity B by 1 day and Activity C by 1 day. Crash activity E by 2 days. Crash activity C by 1 day and activity E by 1 day. Crash activity B by 2 days. Question 22 The normal cost for an activity is $7,000 and the crash cost is $12,000. The normal time to complete this activity is 8 days and crash time is 4 days. If this activity is crashed by 2 days it will cost an additional: $1000 $1250 $2000 $2500 Question 23 Which of these statements regarding project crashing is true? Crashing is not possible unless there are multiple critical paths. Activities not on the critical path cannot become critical after crashing. Crashing shortens the project duration by assigning more resources to one or more of the critical tasks. Crashing a project often reduces the time it takes for lengthy or complex, but noncritical activities. Question 24 In a CPM/PERT network the critical path is the lowest path through the network. Question 25 highest path through the network. shortest path through the network. longest path through the network. Joe used a project management software package and has determined the following results for a given project.: What is the probability of completing the project over 20 days? 0.3849 0.8849 0.1151 0.7642 Question 26 Joe used a project management software package and has determined the following results for a given project: What is the probability of completing the project within 20 days? 0.3849 Question 27 0.8849 0.1151 0.7642 On an AOA diagram, a represents the beginning and end of activities, referred to as events. path arc branch node Question 28 The LS and LF are calculated using the backward pass through the network. forward pass through the network. values for ES and EF. backward and forward pass through the network. Question 29 Once a project is underway, the project manager is responsible for the people. cost. time. All of these Question 30 The activities that must be completed prior to the start of an activity in question are called the immediate of the activity in question. successors predecessors successors and predecessors followers
