Given the following network, with activity times in weeks, determine the earliest and latest activity times and the slack for each activity. Indicate the critical path and the project duration:
Determine critical path for the project by calculating the slack for each activity
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.

Indicate the critical path and the project duration.arrow_forwardThe project detailed in the table below is contracted for delivery in 11 weeks, with a penalty clause requiring the contractor to pay a penalty of $2000 for each week late. The project must therefore be expedited. The possible reductions and associated costs are shown in the table. Times in the table are given in weeks. Only activity 4 can be expedited two weeks. The other activities can be expedited one week. (a) Determine the critical path(s), the expected duration of the project, and the slack time for each activity (indicate value on network)?
