ELECTRE II provides a structured way to rank potential hydropower sites when several technical and economic criteria conflict with each other.�...

Context and motivation
Selecting a location for a hydropower plant typically involves balancing flow availability, head, and project cost, which rarely point to the same “best” site. In such situations, simple scoring or cost–benefit methods can hide critical weaknesses of an option, for example, an excellent flow but an unacceptably high financial liability.
Why ELECTRE II?
ELECTRE II is an outranking‑based multi‑criteria decision‑making method that works with the idea “site A is at least as good as site B” rather than forcing everything into a single composite score. It explicitly separates supporting evidence (concordance) from strong opposition (discordance), so a very poor performance on a key criterion can effectively act as a veto and prevent an unsuitable location from rising to the top rank.
What this tutorial does
This tutorial walks through ELECTRE II step by step on a hypothetical hydropower‑location problem with three candidate sites (A, B, and C) evaluated using flow, head, and financial liability as criteria. You will see how to define alternatives and criteria, assign weights, build concordance–discordance indices, and apply the ELECTRE II distillation procedure to obtain a transparent ranking of the most suitable site.
How it will help you
By the end of the tutorial, you will be able to implement ELECTRE II for real hydropower siting studies or similar infrastructure planning tasks where multiple stakeholders and criteria are involved. The worked example is deliberately simple and uses imaginary data so that you can focus on understanding the logic of the method before extending it to more complex, real‑world cases.
