Supporting water resource management committees by using multicriteria analysis

Decisions about water resource management are complex in nature, since they involve consequences of environmental, social and economic impacts in the society. The multicriteria analysis is a powerful tool to support this kind of decision, assuring a transparent, structured, rigorous and objective evaluation of the problem. This paper presents a group decision support system model to support committees responsible for water resource management. The model provides a ranking of alternatives through the combined use of the multicriteria methods PROMETHEE II and ELECTRE IV.
