3. For the following seven-activity project, develop a precedence network, calculate all relevant characteristics of each activity (ES, EF, LS, LF, TF), and the project duration. Then go through a repetitive process to expedite the project on a least-cost basis until the project is crashed. The solution should include the precedence diagram and calculations for each activity, and then the cyclical calculation to shorten the project activity by activity in a least-cost manner. What is the total cost of the crashed project? Why is this less than the sum of the crashed costs for the seven activities? Please use Table A (Table A-2.pdf Please provide a detailed answer to this question.

The target network for a project has a duration of 12 months at a budget of $120,000. The following information is available as of data date = 5 months: The project is 1 month ahead of schedule and has cost savings of $10,000. Draw a Cost vs. Time graph showing the BCWS, ACWP, BCWP, Cost Variance, Schedule Variance (in time and in $), BAC, and EAC. Label all elements of the graph clearly.
6 The third question: For a part of a construction project whose activities are shown in Table No. 3, the project was visited on the eighth day after the start of work on it, and it was found that the two actions A and B were fully accomplished. event c a quarter of which was accomplished, activity G was five completed, activity F was completed The completion of a third of It, other activities have not started yet, but it is expected after the end of the event and the existence of a comprehensive ban for a period of 3 days. Therefore, it was decided to postpone the work of Event E for a period of three days (days of ban). In light of the information above, find the time period required to complete the project and the critical path before and after the update Table3 Act.

Based on the statements below, draw the precedence diagram. Find the critical path and estimate the duration of the project. Draw the precedence diagram only. At the start of the project, each of 3 separate activities A, B and C may or may not begin and progress concurrently. D may begin until A is completed. E may also begin only after completion of A. F follows activity B. G cannot be started until both E and F are completed. Completion on both G and H allow J to start. The start of J is further restrained by a notice of completion of D. K follows D and culminates in the same (completion) as J.

Consider a simple project in which four activities describe the basic tasks. This project is presented here as a bar chart drawn as a time-scaled schedule. The sum of the amounts for the activities in the schedule of values approximates the original anticipated cost of the project. The project duration is 5 weeks. After 3 weeks, the following has been accomplished:Activity A-> 100 Percent complete, total cost $900 Activity B-> 40 percent complete, cost to date $1,400 Activity C-> 50 percent complete, cost to date $1,500 For this project, using earned value concepts, determine the schedule variance and the cost variance. State if the project is over or under budget and if it is ahead of or behind schedule.
