Decision Tree Analyzer 6.1

Decision Tree Analyzer by SpiceLogic Inc. is a professional tool for building, visualizing, and optimizing decision trees and influence diagrams. It helps you structure complex choices, quantify uncertainty, and compare alternatives so you can make defensible, data‑driven decisions.

Key capabilities include:

• Intuitive modeling: Create decision, chance, and value nodes on a clean, drag‑and‑drop canvas with automatic roll‑back and clear annotations.
• Uncertainty and risk: Assign probabilities and probability distributions, compute expected value and expected utility, and model risk attitudes using standard or custom utility functions.
• Sensitivity analysis: Run one‑way and two‑way analyses, tornado and spider charts, and threshold/dominance checks to see which assumptions matter most.
• Simulation and VOI: Use Monte Carlo simulation to generate risk profiles and explore Value of Information metrics (such as EVPI and EVSI) to quantify the benefit of reducing uncertainty.
• Bayesian updating: Incorporate new evidence to revise probabilities and refine your models as information evolves.
• Reporting and communication: Produce crisp charts and summaries that make trade‑offs, assumptions, and chosen strategies easy to explain to stakeholders.

Decision Tree Analyzer is designed for analysts, product managers, consultants, researchers, and educators who need transparent, audit‑ready decision models. Whether you are evaluating product strategies, operational policies, clinical pathways, capital investments, or R&D portfolios, it brings clarity and rigor to high‑stakes decisions.
