Multiple decision support methods have been developed to support multi-criteria problems, offering a structured approach. One such method is FITradeoff, which is based on tradeoff, and has a strong axiomatic structure. Implemented in a Decision Support System, FITradeoff offers an experience with low cognitive effort and time demanded by the decision maker. Despite its advantages, some issues remain unclear. In this study, we sought to perform an analysis about the cognitive aspects during the elicitation process using FITradeoff in which the subjects solved decision problems developed by themselves. Two neuroscience tools, Eye-Tracker and a 14-channel EEG were used for neurological and psychophysiological data collection. From the results obtained, analyzes and considerations were made about the elicitation process with FITradeoff and the impact of different types of criteria on the performance of the decision maker. With these findings, it is expected to create direction for improvements in the Decision Support System.

使用神经科学工具探索 FITradeoff 方法的认知方面

已经开发了多种决策支持方法来支持多标准问题，提供结构化方法。其中一种方法是 FITradeoff，它基于权衡，具有很强的公理结构。FITradeoff 在决策支持系统中实施，可提供决策者所需的认知努力和时间较少的体验。尽管具有优势，但仍有一些问题尚不清楚。在这项研究中，我们试图使用 FITradeoff 对启发过程中的认知方面进行分析，其中受试者解决了自己制定的决策问题。两种神经科学工具，Eye-Tracker 和 14 通道 EEG 用于收集神经和心理生理数据。从得到的结果来看，对 FITradeoff 的启发过程以及不同类型标准对决策者绩效的影响进行了分析和考虑。有了这些发现，有望为决策支持系统的改进指明方向。
