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...

In recent years,different objective methods are applied to identify the best option from the available set of alternative for solving a given decision making problem.Analytical Hierarchical Process or AHP is one of such method which is mostly applied in decision making problems where multiple criteria is considered before selecting the best solution among the available set of solutions.This tool will help to identify the best solution with the help of AHP method from a set of feasible solutions to solve the given decision making problem. Suppose we want to select the best location for installation of a hydro power plant. Such kind of power plant require sufficient amount of flow at a regular frequency throughout the year.The interconnection length or the distance between the two banks of the river must also within the suitable limit. So Amount and Frequency of Flow including the Interconnection Length of the available locations can be selected as the Criteria by which the availab...
