Hello....
 
 
PERT++ (An enhanced edition of the program or project evaluation and
review technique that includes Statistical PERT) in Delphi and
FreePascal was updated to version 1.32
 
I have included the following inside the zip file:
 
I have also included a 32 bit and 64 bit windows executables called
CPM32.exe and CPM64.exe (that take the file, with a the file format that
i specified in the Readme.CPM file, as an argument) inside the zip, they
run the CPM solver that you use with Statistical PERT that i have
included inside the zip file, you need to compile CPM.java with
compile.bat before running them.

PERT32.exe and PERT64.exe (that take the file, with a the file format

solver, it is a very powerful tool, you need to compile CPM.java with
compile.bat before running them.

Hello....
 
 
I think PERT++ is powerful, because read about Monte Carlo simulation
weakness:
 
Why Monte Carlo simulations of project networks can mislead
 
"Simulations rarely consider management actions, running through each
iteration in a "dumb" fashion. This gives rise to results indicating
that projects might underrun or very considerably overrun, whereas, in
reality, management actions would often bring those overruns forward
even at significant cost. Indeed, many of the actions management carry
out to catch up a late-running project cannot be modelled in a naïve
network simulation, because they involve changing the network (e.g., by
bringing an activity forward to start it earlier than would otherwise be
sensible, thereby breaking a dependency; or taking serial activities and
making them parallel). Since a Monte Carlo network simulation assumes
that the network is fixed and unchangeable (except in some simulations
by branch points that allow different paths to be taken), such actions
cannot easily be modelled."

So PERT++ is much easier to model this.
