Alright, this question has come up once or twice now.
What kind of an example do you want to see, what do you want my basic assumptions to be?
I could try and whip up a quick example both with labview and by hand. I can't promise the most, i'll need my systems dynamics book, which is at home currently. Maybe i can boost one from someone else where.
Get back to me quickly, I've got this morning to run with it. And maybe tonight if i get really bored (don't bank on that).
Sincerely,
ElSmitho
