Carlo Simulations 
Monte
Carlo is a technique to calculate the uncertainty in a forecast
of future events. It assumes you are using some kind of mathematical
model. Financial planning abounds with such models.
Instead
of using a single value for each variable in a model, say
investment returns, it uses many values. A Monte Carlo "engine"
runs the model over and over again, each time using a different
value for each of the variables in the model. Each run is
called a "trial". The outcomes are tabulated, and
after a large number of trials, the forecast is shown not
as a single value, but as a range of values. In other words,
the uncertainty is explicit.
The
selection of the value for the variable for each trial is
random. But, the permitted values of the variable are not
random. They are carefully constructed using the best knowledge
as to how the variable behaves.
The future is uncertain, therefore the assessment should take
into account the uncertainty. What are likely future investment
returns, inflation, etc.?
Monte
Carlo is one such technique that greatly increases our grasp
of the consequences of uncertainty.
