The diagram in Figure was developed for the project launch of Kitty Condo, a new product in the luxury cat cage market. Suppose that you, as project manager, are interested in finding ways to speed up the project at minimal additional cost. Determine the schedule for completing the project in 25 days at minimum cost. Penalty and project-overhead costs are negligible. Time and cost data for each activity are shown in Table.
Please, I need help because I have no idea how to do any of these.
11. Building a backyard swimming pool consists of nine major activities. The activities and their immediate predecessors are shown. Develop the project network.
For question number 12, you need to refer to question number 11. Also the first picture is for #11 and second picture(image) is for #12
12. Assume that the activity time estimates (in days) for the swimming pool construction project in Problem 11 are as follows:
a. What are the critical activities?
b. What is the expected time to complete the project?
c. Based only on the critical path, what is the estimated probability that the project can be completed in 25 or fewer days?
The following table contains a list of activities, with precedence requirements and crash costs. All start and finish times and crash costs are on a per-week basis.
a. Draw the network diagram for the project below.
b What is the critical path and completion time for the project?
c. Determine the least expensive project cost if the duration is to be 10% shorter than normal project duration.

- 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_forwardA project has the activity duration and cost information indicated in the table where all times are in weeks.
