Project Evaluation & Review Technique (PERT)

Project Evaluation & Review Technique (PERT) :-

This is also used for project activities .

In PERT each activity will have THREE time estimation:-

(1). Optimistic Time

(2). Most Likely Time

(3). Pessimistic Time

PARAMETERS :-

(1). Mean expected duration :-

Te = [ (To + 4Tm + Tp) / 6 ]

(2). Variance :-

Var. = [ ( Tp - To ) / 6 ]^2

(3). Critical Path :-

Esi = Max. ( Esi + Dij )

Lci = Min. ( Lcj - Dij )

NOTE :-- Condition for Critical Path :-
1. Esi = Lsj
2. Lci = Lcj
3. Esj - Esi = Lcj - Lci = Dij.
