Re: Somebody help me please!! ramp and pulse train combination
1- How can I ovecome the problem 'simulataneous equations' using the Vensim PLE? is there any trick there? The built in functions in Vensim PLE are very scarce. Can you post the model here so we can take a look? Simultaneous equations are common, and usually easily fixed with an adjustment to the l...

Re: Somebody help me please!! ramp and pulse train combination
1 - Every feedback loop must have a stock in it. This is not only a PLE limitation, it's also reality. A simultaneous equation loop might be a workaround for some "stiff model" situation, like a rapid market-clearing process embedded in a model with slow dynamics, but more often it's a co...

Somebody help me please!! ramp and pulse train combination
Hi there!! I started to use Vensim PLE (the free version) just a couple of weeks ago, so I have still a long way to go. I would like to ask the following questions: 1- How can I ovecome the problem 'simulataneous equations' using the Vensim PLE? is there any trick there? The built in functions in Ve...
