Activity A can start as soon as the project starts, and set the earliest start time for activity an equal to 0. With an expected activity time of 5 weeks. Using this information what is the earliest finish time for activity A?
Below is a network diagram that represents a university revamp project. The project manager analyzes this project using the critical path (CP) method. Activity durations are indicated on the network
A project has 7 activities P, Q, R, S, T, U, and V. Three time estimates (optimistic, most-likely, pessimistic) are used for each activity. Write down your answers to all parts of the question in the box given below. Give your answer to 3 decimal places. (Note (a) has of 2 parts and (b) has of 3 parts) For activity Q, these time estimates are as follows: optimistic time = 9, most-likely time = 14, pessimistic time = 20. Write down the average activity time for Q the variance of activity time for Q. The critical path of this project has a mean project time of 44 days and a standard deviation of 5 days. Assume project completion time is normally distributed. Find the probability that the project will be completed in 47 days. Find the probability that the project will take more than 40 days. We want to set a deadline for this project completion. If the probability of meeting this set deadline is 0.88, what will be the deadline for this project.

In the space provided below create the network diagram that shows the relationship (logic) of project activities shown below and then number each event. 1. In a given project activities "A, B and C are initial activities that may begin at the same time 2. -----"D" cannot begin until "A" is complete. 3. ----- "B" must be complete before E can begin. 4. ----- "F" cannot start until "C" is finished. 5. ----- "G" cannot begin until "B" is finished. 6. ----- "G" and "D" must be done before "H" can begin. 7. ----- "I" cannot begin until "B" is finished. 8. ----- "J" can begin only after "F" and "I" are complete. 9. ----- Once "E" is complete, "K" can begin. 10. ---- The project will be finished when "H" "J" and "K" are complete.
The following eight activities constitute an overall bar chart portrayal of a 4-month project. Two months after the start of the project. Activities A, C, D are completed, E is 50% complete and B is 25% complete. The total cost that has been spent is $10,500. For this project, using earned value concepts, determine the schedule and cost variance. Is the project ahead or behind schedule? Over or under budget?

A project is set to be completed in 12 months with an estimated budget cost of $520,000. 6 months have passed, and expenses were $240,000. The completion of work is set to be $270,000 What is the planned value PV of the project? What is the actual cost AC of the project? What is the earned value EV of the project? Find the SPI and CPI of the project. Is the project ahead or behind schedule? Is the project under or over budget? What is the estimated cost to complete the project?
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: Dave's earliest start (ES) and earliest finish (EF) are: Activity Time (weeks) Immediate Predecessor(s) Activity Time (weeks) Immediate Predecessor(s) A B C D 7 6 3 2 A A Activity A ES EFGH EF 7 3 6 11 6 B B C, E D, F
Perform the CPM (critical path method) and give the complete activity schedule table, the project completion time and the critical path.
