gert vs pert

[Debbie Rowe]

As my title suggests, I have a pretty small query. I just wanted to know what is the difference between PERT and GERT?

Please provide brief difference. Thanks in advance.

Hello,

GERT = Graphical Evaluation Review Technique

GERT allows several What If simulations in the same graph. But IFAIK, there
no software able to calculate and to display this GERT.
