Supporting the Use of Decision Aiding Methods by Non-specialists.

Multiple Criteria Decision Aiding (MCDA) is a domain focused on the development of methods to help decision makers. DECSPACE is an online Decision Support System (DSS) intended to be a workbench for the use of MCDA methods. DECSPACE supports projects as persistent spaces where users can explore different solutions for the same problem, and share those solutions in other projects. It is made available as an online service, and it can use methods implemented in a local server, as part of the local application, or methods available from remote web services. This paper describes DECSPACE as a DSS suited for use in teaching, researching, or for professional use in engineering and management.
