economic modelling, forecasting, dynamic analysis


For the economic sciences, mainly for the planning and organization disciplines, the models display a range of varieties.  For the last decades, though, the mathematics-based models seem to be the trend, partly because of their ability to rigorously concentrate the essentials and also to be programmed via the computer-based techniques, thus creating together an unheard of instrument of scientific investigation, a resourceful ‚extension’ of human intelligence.The article herein presents certain medium-term prognosis, via the dynamic modelling, elements of bifurcation theory and the Xpp software.  The case study has been the object of a research contract with the business environment.
