Popis: This research intends to develop a model to support the selection of the best strengthening technique to be adopted in rehabilitation projects. This methodology is particularly useful for project teams that need to select the most suitable strengthening technique among several solutions. The model proposed includes the typical variables that capture the main technical characteristics of the strengthening solution and also economic variables associated to the costs of the intervention. The model proposed is based on Data Envelopment Analysis specified with a directional distance function. It has the ability of calculating an overall performance score for each solution showing it in the best possible light. To demonstrate the advantages of the methodology developed, it were used the results of a study conducted in Portugal. From the empirical application, it was possible to conclude that the best strengthening solution may vary depending on whether the costs of the interventions are or not included in the model.
