New Generation Platform for Multi- Criteria Decision Making with Method DEX

DEX is a qualitative multi-criteria decision analysis method. It has been used numerous times in various applications – from everyday decision problems to problems in financial and ecological domains. Based on experience and applications, we identified six methodological extensions to DEX, which form a basis for a thesis in the area of multi-criteria decision support. The extensions are: using full hierarchies, introducing numeric attributes, probabilistic and fuzzy aggregation of values, general aggregation functions, modularization and relational models. The main method DEX with six extensions will be implemented in a library along with a graphical user interface. The performance of the newly developed methods and tools will be empirically evaluated through four real usecases.
