Project network. O Early, late and slack activity times. o Project duration. o Critical path

12:23 Ill 5G Problem 1 The following table gives expected times and variances for a probabilistic duration type of project (we are not given and we don't need the optimistic, most likely, and pessimistic time estimates). Activity Expected Time Variance A 4 0.44 B 3 0.69 C 7 2.25 D 11 2.25 E 4 0.11 F 9 1.36 G 6 0.44 H 6 0.69 I 7 1.36 J 13 1.00 K 3 0.44

Activity Predecessor Duration A - 6 B A 8 C A 6 D C 4 E B 6 F b.d 7 G C 5 H F,G 6 I E, H 4   Construct the network diagram Find each activity’s ES, EF, LS and LF. Calculate the slack for each activity. How long will it take to complete the project

I'm having trouble creating a project network diagram. I don't understand calculating the time and total slack for each activity using forward pass and backward pass. Please explain how to draw and calculate a project network diagram.

ACTIVITY   Immediate Predecessor   Normal Duration (wks)   Minimum Duration (wks)   Crash Costs ($/wk)   A   ---   4   4   ---   B   ---   3   2   100   C   A, B   5   3   200   D   C   4   4   ---   E   C   2   1   300   F   C   1   1   ---   G   D   3   2   200   H   E   1   1   ---   I   F   1   1   ---   J   H, I   3   1   100                   What is the slack time for Activity F and the late start for Activity H?   Group of answer choices 2 weeks, 11 weeks 1 weeks, 11 weeks 3 weeks, 10 weeks 2 weeks, 12 weeks None of the above are correct.

How do I do this problem?
