TreePlan helps you build a decision tree diagram in an Excel worksheet using dialog boxes.

Decision trees are useful for analyzing sequential decision problems under uncertainty.

TreePlan automatically includes formulas for summing cash flows to obtain outcome values and for calculating rollback values for determining optimal strategy.

SensIt performs sensitivity analysis on your Excel worksheet what-if model.

SensIt automates sensitivity analysis and creates simple plots, spider charts, and tornado charts.

In a decision situation, sensitivity analysis helps you determine which of your input assumptions are critical so that you know where to focus your effort for gathering more information or reducing uncertainty.

SimVoi provides random number generator functions as inputs for your Excel worksheet model, automates Monte Carlo simulation, creates tables and charts, and computes value of information.

SimVoi automates the simulation by trying thousands of what-ifs consistent with your assessment of the uncertainties and displays the results in histograms, cumulative charts, bivariate scatter plots, and value of information charts.
