Area of research: Operational research: mathematical techniques for the treatment of uncertainty in the economy and business managementThe scope of the research is mainly the study and the applications of fuzzy logic in several problems in the economy and business management.At the same time, new techniques will be approached for classifying items from a referential set under conditions of uncertainty or inaccuracy.Research is also being carried out on economic expert systems through the establishment and on expert-opinion aggregation techniques.Finally, work is being carried out, through modelling and simulation techniques, on the establishment of methods for predicting economic-variable values based on neural networks.
