DART (Decision Analysis by Ranking Techniques)

DART (Decision Analysis by Ranking Techniques) is a powerful and user-friendly software tool designed for the ranking of chemicals according to their environmental and toxicological concern based on the most recent ranking theories. Different kinds of order ranking methods, roughly classified as total (also called even-scoring) and partial-order ranking methods (Hasse diagram technique), are implemented in DART. These methods can be used to rank chemicals on the basis of more than one variable.

DART was developed by Talete srl (Milan, Italy) under the terms of a JRC contract. The software is made freely available as a service to scientific researchers and anyone with an interest in the application of computer-based ranking methods.

Key features

    • Easy to install.
    • Different kinds of total ranking techniques are implemented: desirability, utility, dominance functions and others.
    • The partial ranking technique called the Hasse diagram is also implemented.
    • A total of 19 different kinds of functions allow the user to explicitly define the best condition for each variable used in the decision process.
    • A weighting scheme is also implemented to take into account the importance of variables in the decision rule.
    • Principal Component Analysis is implemented, with graphical options to evaluate laodings and scores and to save a user-defined number of principal components as new variables.
    • A clustering method allows the selection of a user-defined number of samples for each cluster.
    • Separate significant digit depletion for each variable and broad order statistics are also implemented.
    • Results are provided in a professional graphical user interface. Pareto plots, histograms, line plots and 2D / 3D scatter plots are implemented.
    • An electronic manual is provided.
