CPM prob-3

  1. From the following data construct a NWD
  2. Identify the critivcal path & project completions time
  3. Construct a critical schedule
  4. If activity A is delayed by 2 days, find out whether project completion time is affected or not.
Activity Predecessor Duration (in days)
A - 3
B - 1
C A 4
D B 4
E B 5
F D 2
G E 3

NWD diagram

 

Critical path

Path Duration
A-C 3+4     =7
B-D-F 1+4+2  =7
B-E-G 1+5+3  =9 - Critical path

Table calculating various matrix

Activity Duration EST EFT LST LFT TF
A (1-2)            
B (1-3)            
C (2-4)            
D (3-4)            
E (3-5)            
F (4-6)            
G (5-6)
