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?
Consider the project described in the table below: Activity Duration A B C D E F G H 9 4 8 8 5 7 4 6 OEST-9 and LCT = 15 OEST=9 and LCT = 13 Immediate Predecessor What is the earliest start time (EST) and latest completion time (LCT) of activity B? OEST=9 and LCT = 20 OEST-9 and LCT-17 - A A A B B,C C,D E,F,G
The following is a table of activities associated with a project at Rafay Ishfaq's software firm in Chicago, their durations and what activities each must precede: Duration (weeks) Precedes B, C E F F Activity A (start) What is the total slack for the non critical path(s) in the project? BOE C F (end) 1 2. 2182 This exercise contains only parts b, c, and d. b) The activities on the critical path are c) The total project completion time for Rafay Ishfaq's software firm is weeks.
