Solution

The Precedence network diagram of activities as follows :

                                                                                                              A

                                                                                                               B

                                      C

                                                              D

                                                                                              F

                  E

                                                                                                    G

The possible paths and their corresponding durations as follows :

A-B-C-F-G = 4 + 7 +9 + 10 + 11 = 41 weeks

A-B-D-F-G = 4 + 7 +3 + 10 + 11 = 35 weeks

A-B-D-E-G = 4 + 7 + 3 + 14 + 11 = 39 weeks

Since , A-B-C-F-G has the longest duration, it is the Critical path

The duration of the project ( which is same as the duration of the critical path ) will be 41 weeks

CRITICAL PATH = A-B-C-F-G

THE PROJECT WILL TAKE 41 WEEKS

It is to be noted that all activities lying on Critical path will have Zero slack. Therefore, activities A,B,C,F and G will have ZERO slack

Slack of activity D = Duration of A-B-C-F-G – Duration of A-B-D-F-G = 41 – 35 = 6 WEEKS

Slack of activity E = Duration of A-B-C-F-G – Duration of A-B-D-E-G = 41 – 39 = 2 WEEKS
