Question 17 5 pts Given the Network Diagram below, what are the LS and LF for Activity C? Activity A Duration = 6 Activity B Duration = 5 Start 12 18 Activity C Duration = 7 Finish 1 3 Activity D Duration = 2 OLS = 11, LF = 17 OLS = 12, LF = 18 OLS = 12, LF = 19 OLS = 13, LF = 18 What is the LS value for Activity E in the path shown below. Note that for Activity H, LF = 17. 17 0 13 07 0 O 14 0 o 6 If the first time you perform a job takes 60 minutes, then how long will the fourth (8th) job take if you are on an 80% learning curve? Note: You should use the equation for Learning curves that are based on a doubling of productivity: TN = T1xL" = Time required for the Nth unit, where: o In = unit cost or unit time of the Nth unit o L = decimal learning curve rate (e.g., 0.8 for 80% learning rate) o n= number of times Tis doubled on= number of times T is doubled (e.g., doubling from unit 1 to unit 2 is once, from unit 2 to unit 4 is twice, ...) O 30.7 minutes O 51.2 minutes 0 41.0 minutes O 38.4 minutes
