Module for calculation PrefRank scores using preference information given by decision maker.
(For outputs, see below)
Alternatives to consider.
Aggregated preferences matrix.
Preference information about alternatives. Strength for the alternative is given to the value of true, weakness for false, when no value is given, the alternative does not gain strength or weakness.
Parameter specifies the algorithm to calculate ranking. There are three algorithms to choose from: PageRank, HITS and Salsa.
Parameter values can be defined via the GUI or the XMCDA file, by default via GUI.
Name: algorithm type
Name: damping factor
Damping factor
Name: number of iteration
Number of iteration
Name: Run averaging if not converge?
Turning on the version with averaging the score value, if after “number of iteration” iteration the score does not converge, that is: the maximum score difference between the last two iterations is greater than 0.001.
Name: Earlier stop if converge?
Earlier stop if the maximum difference in score between two consecutive iterations is less than 0.00001
