Multicriteria Evaluation in a Fuzzy Environment

The presence of qualitative information in environmental policy analysis is a rule, rather than an exception. This work is mainly concerned with the issue of fuzzy information in multicriteria evaluation. New analytical tools able to tackle economy-environment interactions and operationalize equity issues are presented. The behaviour of such mathematical procedures is shown by means of real world environmental management problems. Moreover, the consistency between the methodology of multicriteria evaluation and the epistemological foundations of ecological economics is investigated in depth.
