Video Demonstration for Rational Will

Treat uncertainty with wisdom. It is a tool that infers the risks for you.

Decision Tree Maker & Analyzer Software with Intuitive User Experience

Because you do not deserve the pain of a poorly designed, boring, and awkward user interface for Decision Analysis, SpiceLogic has brought you the most Intuitive and beautiful wizard-like Decision Tree Analysis Software. The user experience is intuitive enough so that you don’t need to learn through a manual. You can intuitively guess the correct way to achieve what you want to model. Learn More
Decision Tree Maker

Easy Manipulation of a Decision Tree

Not only can you make a decision tree, but you can also manipulate the tree in any productive way you want. You can cut or copy a subtree and replace a node with the subtree easily. Forgot to add a decision node between 2 nodes? No worries. You can insert a decision node, chance node, or a parallel node quickly from the context menu. Learn More

Perform Sensitivity Analysis

Sensitivity analysis is a crucial part of decision analysis. A decision won't be robust until a sensitivity analysis is performed. Decision Tree Maker & Analyzer software calculates the sensitivity of all variables and display a sorted list based on the degree of sensitivity. Learn More
Sensitivity Analysis

Diverse payoff info with multiple objectives and criteria

The decision tree software is capable of capturing multiple objective / multiple criteria in a rich format like boolean, subjective, numerical, monetary, etc. Learn More
Multi Criteria Decision Analysis

Rich math expression editor for Multi-Criteria Utility Function and Monte Carlo Simulation

Drag and drop criteria to the expression editor, and use a mathematical operator and built-in functions to form your custom expression. You will love this editor when you will need to perform a Monte Carlo simulation of your Random Function. Learn More
