NAIADE is software for Multi-Criteria Analysis (MCA) which has been developed by Giuseppe Munda, in cooperation between the Autonomous University of Barcelona and the Joint Research Centre of the EC (in Ispra). It is a discrete multi-criteria method whose impact (or evaluation) matrix may include either crisp, stochastic or fuzzy measurements of the performance of an alternative with respect to a judgment criterion gm, thus it is very flexible for real-world applications. This makes it particularly sutiable for particularly suitable for economic-ecological modelling incorporating various degrees of precision of the variables taken into consideration. For more details see this short 3-page technical description.
