“…Our approach is based on the use of fuzzy logic expert systems (Novák, 1995;Pokorný, 1996). Experts systems, in particular using fuzzy logic are in this area used by a number of authors for different applications (Xu et al, 2010;Zhang et al, 2004;Zhang and Liu, 2005). The applications of artificial neural networks or tools of soft computing are also very interesting.…”
