Hi to all

Which option does software use for CPM computations {Considering Forward Pass alone }

Option 1 EF = ES + D − 1.
Option 2 EF = ES + D.

Is there any advantage in selection ?
As both gives the same result on work out.

All comments form seniors are more appreciated

    Shahul,

    I am no senior, hence this is the answer of a novice.
    As you have said, both formulae gives the same result, then there isnt any advantage over the other. Option 1 is used when the 1st event numbering is set to 1 while the other has been set to 0.

    Cheers,

    Bill

    Dear Shahul,

    This is the formula used by Primavera:

    Option 1 EF = ES + D − 1.

    With kind regards,

    Samer

    I published an article about this very subject in the AACE International Journal in 2003 called, “How to Befuddle a College Professor (without Really Trying).” You can read it on-line at http://ronwinterconsulting.com/published.htm. Good luck!
