01

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.

03

Create a Markov Chain, simple or complex, directly into the tree.

As a healthcare student, you will be glad to know that, you can model your Markov chain within the Decision Tree analyzer. You can add Rewards to a state to turn your Markov Chain into a Markov Decision Process. You can add multiple Markov nodes and complicate the decision model as you wish.

06 Perform Sensitivity Analysis Sensitivity analysis is a crucial part of decision 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.
