FITradeoff Decision Support System Applied to Solve a Supplier Selection Problem

The world’s digital transformation changed organizations’ routines completely. Decision Support Systems have been developed to support Decision-Makers to capture information intended to permit competitive advances. In this context, regarding Multi-Criteria Decision-Making/Aiding problems, several DSSs have been proposed to support DMs to deal with complex problems. This paper presents the DSS constructed to implement the FITradeoff method. Several steps of the FITradeoff DSS have been described considering a supplier selection process. In addition, the paper presents behavioral studies performed to investigate the FITradeoff method in a synthesized way. The probability of success, which is an important feature proposed by behavioral studies, has been discussed since it can be used by analysts to advise decision-makers during the decision process. This feature uses previous knowledge of holistic evaluation studies to advise decision-makers to use or not use visualizations to perform holistic evaluations in the FITradeoff Decision Support System. Behavioral studies in the FITradeoff DSS provide modulation (transformations) on it, bringing important advances to this area of knowledge.
