A simple CPM network has three activities, A, B, and C. A is an immediate predecessor of B and of C. B is an immediate predecessor of C. The activity durations are A=4, B=3, C=5. The network has no critical path. The critical path cannot be determined without knowing PERT expected activity times. The critical path is A-C, duration 10.5. The critical path is A-B-C, duration 9. The critical path is A-B-C, duration 12.
Given the following activities and precedents, draw a PERT/CPM diagram. ACTIVITY IMMEDIATE PREDECESSOR DURATION (DAYS) A - 10 B - 12 C A 4 D A, B 8 E A, B 9 F C 10 G D, F 12 H E, G 15 Answer the following: What is the critical path? How long will it take to complete this project? Can activity E be delayed without delaying the completion of the project? If so, how many days?
Given the following information about a small project, Task Duration Immediate Estimates Predecessors A 2 days None B 5 days A C 4 days B D 9 days A E 4 days B & D F 12 days E & C Draw a network diagram. Identify the critical path, earliest start and finish and slack for each task. Using MS Excel, produce a Gantt chart for this project. What would happen if a new estimate for task D increases...
The following activities are part of a project to be scheduled using CPM: ACTIVITY IMMEDIATE PREDECESSOR TIME (WEEKS) A — 3 B A 9 C A 5 D C 2 E B D 7 F D 6 G E F 4 b. What is the critical path? A-B-D-F-G A-B-E-G A-C-D-F-G A-C-D-E-G c. How many weeks will it take to complete the project? Number of weeks d. How much slack does activity B have? Slack of activity B week(s)
Question 14 Not yet answered A simple CPM network has five activities, A, B, C, D, and E. A is an immediate predecessor of Cand of D.B is also an immediate predecessor of Cand of D. C and D are both immediate predecessors of E. Which of the following statements is true? Points out of 1.00 P Flag question Select one: a. There are four paths in this network b.

Develop the earliest start and finish times, the latest finish...
Given below is the crashing data for a project along with other data. The project completion time is 20 davs. Determine: (a) the crash slope (i.e crash cost/day) for all activities, (b) the normal total project cost, (c) prioritized the list of activities for crashing from best to worst, (d) the best activity to crash if the project has to be completed in 19 days and alternative critical paths, if any, (e) the earliest time the project can be completed,...
