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: Activity Time (weeks) Immediate Predecessor(s) Activity Time (weeks) Immediate Predecessor(s)A 7 - E 4 BB 8 - F 7 BC 4 A G 11 C, ED 1 A H 6 D , F Dave's earliest start (ES) and earliest finish (EF) are: Activity ES EF A 0 7 B 0 8 C 7 11 D 7 88 E 8 12 Part 7 F ? ?

Swimming Pool Installation: You are the project manager working for Mack's Pool Co. Your project consists of installing a new swimming pool at the local country club before Memorial Day weekend (pool opening weekend). You would like to find the minimum cost schedule for your project. There is a $9,000 per week penalty for each week the project is delayed beyond week 9. In addition, your project team determined that indirect costs are $15,000 per week.

Consider the following project where times are in weeks. Activity Immediate Predecessors Duration A - 8 B - 12 C A,B 7 D B 4 E A 2 F C 3 G E,F 7 H D,F 3 What is the slack for activity G? a. 7 b. -7 c. 0 d. 1 There have been several variances in the cost and schedule estimates on your project, and the original estimating assumptions are no longer valid. The variances will likely continue until the end of the project. Calculate the estimate at completion (EAC) for your project based on the following data? BAC = $1,000,000 EV = $200,000 PV = $400,000 AV = $150,000 CPI = 1.333SPI = 0.5 a. $1,425,142 b. $751,879 c. $1,050,000 d. $1,200,120

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.
What is the value of the missing item labeled (a) in the table above? Round to the nearest integer. What is the value of the missing item labeled (b) in table above? Round to two decimals. Draw the network diagram for this project. Clearly label the earliest start, earliest finish, latest start, latest finish and slack for each activity. Specify the critical path and the critical activities. State the expected C.P. duration State the variance of the critical path. What is the probability that the dashboard will be delivered within 20 days?
