In this presentation we highlight diviz, a platform for designing, processing and sharing Multicriteria Decision Aiding (MCDA) algorithms and experiments. One of its main features is the possibility to design complex MCDA algorithms by combining elementary calculation components via an intuitive graphical user interface. The target user community of diviz reaches from researchers to teachers, students and MCDA analysts solving real-life decision problems. The diviz software also eases the comparison of results produced by different algorithms on the same decision problem instance and facilitates the dissemination of MCDA methods and experiments.
