The Complete Risk and Decision Analysis Toolkit

Wouldn’t you like to know the chances of making money on your next venture? Or which of many decision options is most likely to yield the best payoff? How about the best sequential drilling strategy? Or how much to invest in various projects in order to maximize the return on your project portfolio?

Everyone would like answers to these types of questions. Armed with that kind of information, you could take a lot of guesswork out of big decisions and plan strategies with confidence. With the DecisionTools Suite, you can answer these questions and more – right in your Excel spreadsheet.

The DecisionTools Suite is an integrated set of programs for risk analysis and decision making under uncertainty that runs in Microsoft Excel. The DecisionTools Suite includes @RISK, which adds risk analysis to Excel using Monte Carlo simulation, PrecisonTree for visual decision tree analysis, TopRank for what-if analysis, NeuralTools and StatTools for data analysis, and RISKOptimizer and Evolver for optimization. Rounding out the Suite is BigPicture for mind mapping, diagramming, and data exploration.

Programs are designed to work together, and all integrate seamlessly with Microsoft Excel for ease of use and maximum flexibility.
