Description

-Contact: Patrick Meyer (patrick.meyer@telecom-bretagne.eu)

Computes rankings on the alternatives by distillation of alternatives’ qualification. Requires a 0-1 valued outranking relation as input. The partial ranking (intersectionDistillation) is obtained by taking the intersection of upwards and downwards distillation preorders (which are also provided). Similar to an Electre III distillation.

Inputs

alternatives

Description:

A list of alternatives. Alternatives can be activated or desactivated via the <active> tag (true or false). By default (no <active> tag), alternatives are considered as active.
