Improving preference disaggregation in multicriteria decision making: incorporating time series analysis and a multi-objective approach

Autor: Campello, Betania S. C., BenAmor, Sarah, Duarte, Leonardo T., Romano, João Marcos Travassos

Preference disaggregation analysis (PDA) is a widely used approach in multicriteria decision analysis that aims to extract preferential information from holistic judgments provided by decision makers. This paper presents an original methodological fr

This work proposes the application of independent component analysis to the problem of ranking different alternatives by considering criteria that are not necessarily statistically independent. In this case, the observed data (the criteria values for

In many ranking problems, some particular aspects of the addressed situation should be taken into account in the aggregation process. An example is the presence of correlations between criteria, which may introduce bias in the derived ranking. In the

A study of the Multicriteria decision analysis based on the time-series features and a TOPSIS method proposal for a tensorial approach

Autor: Campello, Betania S. C., Duarte, Leonardo T., Romano, João M. T.

A number of Multiple Criteria Decision Analysis (MCDA) methods have been developed to rank alternatives based on several decision criteria. Usually, MCDA methods deal with the criteria value at the time the decision is made without considering their

Autor: Pelegrina, Guilherme D., Brotto, Renan D. B., Duarte, Leonardo T., Attux, Romis, Romano, João M. T.

Publikováno v: IEEE 2022 International Joint Conference on Neural Networks (IJCNN), 2022, pp. 1-8

In dimensionality reduction problems, the adopted technique may produce disparities between the representation errors of different groups. For instance, in the projected space, a specific class can be better represented in comparison with another one
