Hi everybody, we are a group of students. We are studying the basis of the web services technology. We have to create a complex informative system, part of which consists of a DSS (decision support system). We need to use something already existing, giving in input our alternatives and criteria and receiving in output a graph, or a classification of the alternatives. The criteria are 4 and fixed. We don't need constraints. the alternatives are not fixed.
