Question

Figure 8.26 Work-flow diagram for problems 4 and 5. 6. Determine the critical path and the probability of completing the job of Figure 8.27 in 28 days. As in the preceding problems, the first number adjacent to each activity is the time in days and the second number is the standard deviation. Show the critical path. Determine the float, free float, independent float, and slack for activities and events in Figure 8.27. 7.

Explanation / Answer

Problem 1:

Path 1: ABDHI : Duration = 5+2+5+3+5 = 20

Path 2: ABEGI : Duration = 5+2+5+2+5 = 19

Path 3: ACFGI : Duration = 5+4+5+2+5 = 21

The project will take 21 days to complete

Critical path is ACFGI
