ModelChoice

version 1.0

The first public release of ModelChoice — the complete decision-analysis toolkit, native to Microsoft Excel.

• Build decision trees directly on the worksheet as native Excel shapes, with branch values, probabilities and payoffs held in real Excel cells.
• Continuous rollback — the optimal strategy and the expected value of every node re-solve automatically as inputs change, with no "run" step.
• Sixteen analytical reports from a single ribbon click: risk profile, one- and two-way sensitivity, "Break the Decision" robustness scoring, Force to Outcome, policy suggestion, value of information (EVPI and EVII), and the board-ready Decision Brief.
• Multi-criteria decision analysis (MCDA) with AHP pairwise weight elicitation and consistency-ratio checking.
• Utility-function rollback with certainty equivalents and risk premiums for risk-averse stakeholders.
• Continuous-distribution Monte Carlo simulation through integration with ModelRisk.
• One-click import of existing models from PrecisionTree.
• JSON export and import of trees, an automation API for Python, .NET and VBA, and approximately sixty industry example models.
• User interface and documentation localised in seven languages.
