ELECTRE II: Step by Step : Watch the Video Lecture First, a decision matrix is defined, criteria are classified (benefit/cost), and weights are assigned to reflect their relative importance. Then, for each pair of alternatives, concordance indices (measuring the strength of support) and discordance indices (measuring the strength of opposition) are computed and compared with thresholds to determine strong and weak outranking relations. Finally, ELECTRE II uses these strong and weak outranking graphs in a two‑phase distillation process (descending and ascending) to derive a complete or partial ranking of the alternatives. Typical applications Widely used in engineering, transportation, water and environmental management, logistics, and policy planning where decisions involve multiple criteria and stakeholders. Particularly useful when decision make...
