ESTADO DE LA CUESTIÓN ACERCA DEL USO DE LA LÓGICA DIFUSA EN PROBLEMAS FINANCIEROS.

This paper discusses the current status of the use of diffuse set theory applications and diffuse inference systems in solving financial problems, specifically in the areas of company portfolio theory, project assessment, credit analysis, technical analysis, and financial analysis. They enables incorporating uncertainty into the analysis in a different manner from the one used in the theory of probabilities. The paper also includes a critique of traditional financial decision-making models, which do not clearly capture market behavior dynamics. Using this new approach, it is possible to gather economic and financial phenomena along with all of their inaccuracies and treat them mathematically. Furthermore, expert criteria may be incorporated into the analysis, thus making the models developed true support tools for decision making. However, present-day theoretical developments tend to merge knowledge-based technologies to solve many engineering problems and that opens a whole new area of research to apply them to Social Sciences and Economic Sciences.
