The DTT implements some of the most popular and applied algorhythms originated from the Decision Theory Area:

- Multi Value Attribute Theory;
- Hierarchical Analysis
- Electre III

These methods have proved to be a valuable mean to help decision makers extract a rank from a pool of alternatives, each alternative representing a set of actions, on the basis of the qualitative/quantitative impact each alternative has on a manifoldness of indicators.

The functions developed fully emulates the methods above mentioned, handling exceptions arising from a particular input dataset.

The Multi Value Attribute Theory function (MAVT) lets you either directly provide the weight vector (a weight factor for each indicator) or interactively derive it through a succession of couples-preference test.

The Hierarchical Analysis function (HYEA) lets you define incomplete hierarchical structures on the input dataset.

The DT Toolbox contains a GUI demo, DTdemo, providing users with an overview of the capabilities offered by the functions herein implemented.
