Comparative study of hydraulic structures alternatives using promethee II complete ranking method

Hydraulic structures have a direct, strong and long-lasting impact on the economy and society in general. Providing the proper structural solution implies finding a balance between economic, environmental and social requirements while decisions taken are associated with serious and irreversible consequences. Optimization techniques play a key role in finding the right solution. In this paper, for a selected stretch of a river, PROMETHEE complete ranking method was employed for selecting the appropriate solution for river training works. This study goal is to determine the level of agreement and to test the sensitivity of the results obtained by two techniques ELECTRE simplified and PROMETHEE method - subjective and objective approach to determining the criterion weight. Findings confirm the justification of implementing both optimization techniques, particularly in the pre-feasibility studies. These techniques still have important implementation and development possibilities, although they have not yet been largely accepted by the engineering community.
