1. Construct a PERT/CPM network for project having the following activities;

------------------------------------------------------------------------------------------------

Activities Leads Time/ Labor

Activities Weeks

------------------------------------------------------------------------------------------------

A - 3 10

B - 2 9

C - 2 7

D A 4 9

E B 2 6

F B 1 10

G C 2 4

H D,E 2 6

I G 3 6

J D,E 3 6

K F,G,H 2 7

L G 1 6

M L 2 5

1. How long will be taken to complete this project?

2. Identify the critical path and slack for every activity.

3. Compare the weekly labor with Earlier Start (ES), Earlier Finish (EF) and Last Start (LS), Last Finish (LF).
