AN OVERVIEW OF THE FITRADEOFF METHOD: NEW METHODOLOGICAL DEVELOPMENTS AND THE NEW DECISION SUPPORT SYSTEM

The FITradeoff method was originally developed in 2016 to address multi-criteria decision problems in the choice problem, considering partial information. Over the last eight years, there have been methodological developments, expanding its application to other problems and combining elicitation paradigms, as well as other refinements and improvements to the original methodological framework. The Decision Support System (DSS) has also evolved, becoming more complete. The new system covers the four decision issues: choice, classification, ranking and portfolio, provides support for the multi-criteria decision-making process, allowing flexible and interactive elicitation of the decision-maker's preferences. Flexibility is highlighted by the integration of preference modelling paradigms: elicitation by decision and holistic evaluation, changes to efficiency. The method and the DSS are widely used in various areas, demonstrating their practical applicability. This study presents the new developments and functionalities of FITradeoff, exploring its stages and facilities.
