I would rather it wasn't a web application.

I still haven't really used it much (except for setups and so on) but when I
ran into it and was told that it was considered robust enough to use for
serious financial systems as compared to the that time mysql (and yes I
understand that mysql (and mariasql (sp?)) now does this much better) well
I like 'good' tools!

A monte carlo system sets up all the foundational parameters. So there is a
formula for every variable. Every variable has its distribution and
every distribution
has its skewness and and and (it can get very very complicated). Then
one defines
the limits on the distribution (setting parameters) which is followed
by an attempt at
solving for all the unknowns given the area of input for each.
Monte Carlo systems enable one to define the either hugely transitory or the
undefinable. The random number part comes into where if variable 's'
in item 'aaa'
has a probable range of '2 to 7 ppm' with an 85% likelihood of being
between (3.2 and
4.6 ppm) well now an number between 3.2 and 4.6 can be used for 's' value in
item 'aaa'. Then the amount of item 'aaa' is entered and the totals of
all listed
values for all items are summed. The summed items are compared to the required
minimums/maximums/desired values for each value. The overall outputs
are compared
and then adjustments are made to have a combined grouping that meets desired
outcomes.

Its a fairly straight forward process when one eliminates the
variation possible in
each of the variables. This elimination itself introduces new
variables which are most
often overcome by a planned excess. (I don't like spending more than I
have to in
trying to get the job done so I'm being quite a bit anal in the
development of the tool.)

Thanking you for your assistance.
