TreePlan for Decision Trees


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 creates formulas for summing cash flows to obtain outcome values and for calculating rollback values to determine optimal strategy.

SensIt for Sensitivity Analysis


SensIt performs sensitivity analysis on your worksheet what-if model and creates simple plots, spider charts, and tornado charts.

SensIt creates tornado charts for both one-way and two-way sensitivity analysis.

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 for Monte Carlo Simulation


SimVoi provides random number generator functions as inputs for your model, automates Monte Carlo simulation, computes value of information, and displays the results.

Your spreadsheet model may include various uncontrollable uncertainties as input assumptions. Examples are demand for a new product, uncertain variable cost of production, and competitor reaction. You can use simulation to determine the uncertainty associated with the model’s output (e.g., annual profit).

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.
