Selection of the best rehabilitation solution using multicriteria decision analysis

MCDA is performed using different criteria from three dimension of analysis (performance, cost and risk) and is applied to a case study in Portugal. Two external scenarios, four rehabilitation alternatives and six evaluation criteria were considered to test the decision context.
