Hello, Why do we need to
Hello,
Why do we need to take [-2] in account while calculating duration of activity 4? Activity 3 can be finished together with activity 2 and has 0 duration. Then all we have is FF+3 which will result in [6+3 =9] for activity 4
Activity A
<----------------------------------->
0 19 = 20 days
Activity B
<----------------------------------->
20 29 = 10 days
Activity C
<----------------------------------->
25 29 = 0 days
Activity 4 [ 30,31,31 for lag time of 3]
<-------------------------------------> = 3 days of leg + 6 days = 9 days
33 38
so total should be 39?
Can someone help here?
