a) Develop the project network for this problem. b) Determine the expected duration, variance and standard deviation for each activity. c) Determine ES, EF, LS, LF and slack time for each activity. d) Determine the total project completion time and critical path(s). e) Determine the probability that the project will be completed in 34 days or less. f) Determine the probability that the project will take longer than 29 days or less.
11-19 The Laurenster Corporation needs to set up an assembly line to produce a new product. The following table describes the relationships among the activities that need to be completed for this product to be manufactured.
Modified Problem 11-19: Solve the problem, assuming the following data has changed for 3 activities:
- Activity A: a = 4; m =7; b =6
- Activity B: a = 6; m = 9; b = 12
- Activity I: a = 4; m = 5; b = 7
Note to correct a textbook typo: Immediate Predecessors for Activity H are: E, F and G
