Practice Problems -Network Diagram

 

Practice Problems

  1. Draw a network diagram for the following activities:

    ActivityTime (days)
    1-23
    1-32
    2-44
    3-45
    4-56

  2. Construct a network diagram and determine the critical path for the following activities:

    ActivityTime (days)
    1-22
    1-33
    2-45
    3-56
    4-62
    5-63

  3. Develop a network diagram and find the earliest and latest start and finish times for each activity:

    ActivityTime (days)
    1-24
    1-33
    2-57
    3-46
    4-52
    5-68

  4. Draw the network diagram and calculate the total project duration and slack time for each activity:

    ActivityTime (days)
    1-23
    1-32
    2-46
    3-55
    4-64
    5-67

  5. Construct a network diagram for the following project and determine the float for each activity:

    ActivityTime (days)
    1-25
    1-36
    2-43
    3-57
    4-62
    5-64

  6. Develop a network diagram and use the PERT method to estimate the expected project completion time. Use the formula:

    TE=(O+4M+P)6TE = \frac{(O + 4M + P)}{6}

    Given optimistic (O), most likely (M), and pessimistic (P) times:

    ActivityOptimistic (O)Most Likely (M)Pessimistic (P)
    1-2235
    1-3357
    2-4468
    3-5246
    4-6579
    5-6357

  7. Draw a network diagram and compute the critical path for the project using the following activities:

    ActivityTime (days)
    1-22
    1-33
    2-44
    3-55
    4-66
    5-62

  8. Prepare a network diagram and determine the earliest and latest start and finish times for each activity. Identify the critical path:

    ActivityTime (days)
    1-23
    1-35
    2-42
    3-54
    4-67
    5-63

  9. Construct a network diagram and calculate the total project duration and slack for each activity:

    ActivityTime (days)
    1-24
    1-32
    2-45
    3-53
    4-66
    5-64

  10. Develop a network diagram and identify the activities that have zero float (critical activities) in the following project:



ActivityTime (days)
1-22
1-33
2-44
3-56
4-65
5-6         3

PERT- Program Evaluation and Review Technique

  Program Evaluation and Review Technique (PERT) Introduction In today’s dynamic business environment, project management is crucial for achieving organizational goals efficiently. The  Program Evaluation and Review Technique (PERT)  is a powerful project management tool that helps managers plan, schedule, and control projects with uncertain durations. Developed by the  U.S. Navy in the 1950s  for the  Polaris missile project , PERT has since been widely used in research & development, construction, and large-scale infrastructure projects. PERT is a  probabilistic project scheduling technique  that focuses on estimating the time required to complete each task while considering uncertainty. Unlike traditional project management methods, PERT provides a scientific approach to determining the  expected project duration  and identifying the  critical path , which is essential for timely project completion. Features of PERT: Network-...
