The aim of this presentation is to highlight the latest developments on innovative methodological tools which can support research, teaching and consulting activities in the field of Multicriteria Decision Aid (MCDA). We first focus on the diviz software, which allows to combine very conveniently distributed calculation resources via so-called algorithmic MCDA workflows. In particular, we demonstrate how it can be used to teach MCDA algorithms in a very intuitive and effective manner. Then we present two original tools which should further support the adoption of the XMCDA web-services and the diviz software. First we show the myDiviz web site which allows to store algorithmic MCDA workflows generated by diviz. This web site can for example be used to work collaboratively on a decision problem or to store students' works in an MCDA course. It also implements a search engine which allows to easily find workflows according to various criteria (author, web-services, bibliography, …). Then we present the implementation of two MCDA methods on Android mobile devices (tablet, phone) which use the XMCDA web-services for the calculations.
