Hi Tony,
I am using Vensim DSS and trying to run a model with stochastic elements to it. I need to have repeated runs where random distributions change in each run.
How do I do this? I can only find how to change parameters in sensitivity
simulations.

The easiest way is to change the noise seed for the random number generation and do lots of batch runs (see
http://www.vensim.com/documentation/html/25670.htm for details on how to automate this process using a command file). Basically change the noise seed and save each run under a different name.
Is this what you are after?
