Diviz: A software for modeling, processing and sharing algorithmic workflows in MCDA

In this paper we describe diviz, a software for modeling, processing and sharing Multiple Criteria Decision Aid (MCDA) techniques 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 practitioners. 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.
