Apoio à decisão com integrais de Choquet por modelo semi-supervisionado de sinergias e redundâncias

Abstract

The research involves the context of support for multicriteria decision with Choquet integrals in real problems and of high magnitude, regarding the strategic character or the figures involved, which impact important sectors of the country. In this type of problem, the decision maker is responsible for the general conduct of the process, through the orientation of the participants and, mainly, the establishment of preferences that reflect the needs of the organization or institution he represents. The proposal presented here explores a semi-supervised model that simplifies the decisionmaker's contribution to the process, without requiring the assignment of fixed parameters that prevent obtaining a wider spectrum of results available to the decision-maker. These preferences are described by synergy and redundancy relationships for the interactions of the problem criteria, in the context of Choquet integrals. Grabisch's traditional problem, in which he presents his model of decision support in the educational field, was reviewed and we identified new results that could improve decision-making, as they insert the choice of points of view that invert the original results.
