Expected time for each activity ( E)

= ( a + 4.m + b )/6

 Activity A ( days) M ( days ) B ( days) Expected time = ( a + 4m + b)/6 A 1 3 5 3 B 1 2 3 2 C 1 2 3 2 D 2 3 4 3 E 3 4 11 5 F 3 4 5 4 G 1 4 6 3.83 H 2 4 5 3.83

From the above Predecessor diagram, the possible paths and their corresponding cumulative durations as follows :

A-C-F-H = 3 + 2 + 4 + 3.83 days = 12.83 days

A-D-F-H = 3 + 3 + 4 + 3.83 = 13.83 days

A-D-G-H = 3 + 3 + 3.83 + 3.83 = 13.66 days

B-E-G-H = 2 + 5 + 3.83 + 3.83 days = 14.66 days

Since the path B-E-G-H has the longest duration of 14.66 days, it forms the critical path

 CRITICAL PATH = B-E-G-H
