Multi Criteria Decision Analysis/Aid (i.e. MCDA) represents a set of methods developed to aid decision makers during their decision making processes. In ordert to support these procedures specific software were developed and the links below provide information about some of them and about how to get access to. The fist one is a software I use during my research activities, which was developed by the Laboratory of Intelligent Decision Support Systems at the Poznan University of Technology.

• JMAF software to support the MCDA approach named Dominance-Based Rough Set Approach (DRSA) 
• MCDA software list of the International Society on Multiple Criteria Decision Making
• MCDA software list of the European Working Group on Multicriteria Decision Aiding
• diviz: "a software for designing, executing and sharing Multicriteria Decision Aid (MCDA) methods, algorithms and experiments"
