The developed model relies upon the generation of random
variables from input probability distributions and these are represented
in the model equations by the name of the probability distribution
(e.g. Poisson, triangular etc.) followed by the parameters
in brackets. The model used Monte Carlo simulation techniques
(Vose, 2000) to create the output distributions. Monte Carlo methods
repeatedly select values randomly from distributions to create
multiple scenarios of a problem. Together, these scenarios give a
range of possible solutions, some of which are more probable
and some less probable, resulting in a probability distribution for
the solution parameter.
