Can also use formulas to calculate values. Once your decision is modeled you run a Monte Carlo simulatio. Monte Carlo is a technique that generates random numbers that are statistically significant given the ranges and distribution selected by the user. Generating a value for every uncertain value in your influence diagram represents one possible future. After running thousands of possible futures the program can do statiscal analysis on which is the most likely, etc.
Program includes lots of charts and graphs to help interpet the results.
Also includes on-line help, manuals, tutorials and sample models. Finally, you can get values for nodes directly from Excel. You can also put results directly into an existing Excel spreadsheet.
