Summary
The plethora of classification problems in various real-world decision situations motivated us to develop an innovative multiple criteria decision aiding (MCDA) method. This kind of problems usually involves a set of criteria for assessing the objects of the decision (also called actions) and assigning them to categories that are previously predefined. If they are preferentially ordered, we face an ordinal classification or sorting problem, otherwise, we face a nominal classification problem. We present CAT-SD (CATegorization by Similarity Dissimilarity), an MCDA method designed for nominal classification that innovates by considering (subjective) similarity and dissimilarity between two actions, and the potential interaction effects between criteria. The construction of the decision model using CAT-SD depends on the preferences and judgments of the Decision Maker (DM). We show the web based decision support system where CAT-SD has been implemented, called DECSPACE. It is focused on the user experience, and it aims to provide an easy-to-use interface and an intuitive approach for applying MCDA methods. We describe two studies applying CAT SD: the first one is related to the recruitment and selection process of Special Forces for the Portuguese Army, and the second one is focused on the adaptive reuse of underused buildings for cultural purposes in the city of Turin, Italy. Both studies were conducted using a constructive approach for building a decision model, based on a set of interaction protocols, which involves an interactive process between the DM and the analyst. Indeed, the applicability of the method is diverse. Our research outcomes can bring an added value to the DM, their organizations, and our society.
