ES value using zero method

Pls calculate ES of J using zero method

 

4? 6 ?

 

Regards.

 

A B E so 7?

A B E so 7?

Yes, I too got 7 (using zero method)

But as per key it is 8. They provided answer by considering "one" as below. Now, I am confused as which method to be followed. Pls provide the clarification

 

 

 I got 7 also so what is your sosurce of the question

This question is from Farndales

Farndales & HeadFirst Lans they use 1 method not 0 method..Which ever you are convenient to sue please follow that, predominantly it's ZERO mehtod..

 ES = EF of previous + 1 using this calculation, answer will be 8.

How did you apply the SS relationship between  F  and  J? Can someone please explain?

Thanks.

 

Regards.

It's straight path to J task, so the ES=7.

The depicted SS relationship applies to J directly.  Does it mean that this SS cannot be enforced...i.e. it is meaningless in this particular diagram??

Can someone please clarify?

SS do not have relationship here. Since the task in question having SS do not have any say in getting the succeeding task starting. It is still considering the other task of convergence to decide the start date of the succeedor

If anyone has different way to explain please elt me know.

Well, the diagram shows an SS relation between F and J. There is no lag or lead shown... just plain SS. Meaning that J starts when F starts. That's how we enforce SS/FS/SF/FS relnships, correct? The given SS relation does seem to have a direct bearing on when J starts. Would you agree?

SS means, the succeedor J will not start the activity unless the predecessor  F starts regardless when they finish and you are correct there is no lead mentioned. If I'm correct the SS always comes with lead and FS comes always with lag.

In the above network diagram SS doesn't have any type of influence for the calculating the ES for J.
