Textbook Question
Chapter 6, Problem 11E
A large Southeast city is requesting federal funding for a park-and-ride project. One of the requirements in the request application is a network plan for the design phase of the project. Sophie Kim, the chief engineer, wants you to develop a project network plan to meet this requirement. She has gathered the activity time estimates and their dependencies shown here. Show your project network with the activity early, late, and slack times. Mark the critical path.

Dave Fletcher was able to determine the activity times for constructing his laser scanning machine. Fletcher would like to determine ES, EF, LS, LF, and slack for each activity. The total project completion time
and the critical path should also be determined. Here are the activity times:

- Use the Program Evaluation and Review Technique to represent the project in an activity network. In conjunction with the Critical Path Method, use the activity network to find the shortest time possible to complete the project, to identify the critical jobs in the project, and to determine the earliest and latest that each activity can start and finish without making the project completion longer.a=1, b=1, c=6, d=5, e=2, f=5; andab=1x1=1, bc=1x6=6, cd=6x5=30, de=5x2=10, ef=2x5=10, af=1x5=5.arrow_forwardThe table below represents a IS project set of activities, its expected completion time (weeks) and preceding activities.

It is critical that the following project is completed in 18 weeks, before the next Joint Commission survey. Project activity times are listed in the table attached as an image. Determine the minimum cost-schedule for this project to be completed in 18 weeks. Assume a linear relationship between crash cost and crash time. For example, crash cost per week for activity A can be calculated as: ($650 - $200)/(4-2) = $225. 2.

- The project contains 6 tasks. We completed three tasks (A, B, C), and started two (D, E) but could not complete them. The planned budget for each task, Actual cost we spent so far, completion rate by today according to the plan, and actual completion rate by today are shown in the table.

- Prepare a plan for a small project of moderate complexity (at least 12 activities, with some interdependencies between activities). Your plan should identify the activity by their beginning and ending nodes and by short, descriptive titles. Estimate the times to complete the activities. Prepare a PERT/CPM network. Determine critical path and the expected time for completing the project (Activity Analysis and Event Analysis). Choose a project of some personal interest and knowledge (e.g. building a house, selling a house, political campaign etc.) Your project will be judged by how completely it identifies all activities, the reasonableness of your time estimates and the correctness of your analysis.
