Assessing inconsistencies in the FITradeoff method: a comparison of two preference modeling paradigms

Le résumé fourni par la source

Abstract Many decision‐making processes are susceptible to errors and inconsistencies introduced by decision‐makers (DMs). The development of decision support systems (DSS) has brought about a way to guide DMs through complex decision scenarios. However, due to the complexity of the process, inconsistencies may still arise. In this context, this study investigates inconsistencies presented in DMs preference modeling during the use of the FITradeoff method. This method combines two preference modeling paradigms—holistic evaluation and elicitation by decomposition—to support DMs in expressing their preferences, allowing DMs to alternate between these two paradigms during the process. In this context, on combining both paradigms, inconsistencies can occur during the FITradeoff process. Hence, this study analyzes the occurrence of inconsistencies. For this, 86 DMs applied the method in their own decision problems. The results indicate that the FITradeoff method presents a lower inconsistency rate compared with the Swing and the classical Tradeoff procedures.
