“…The approach, similar to the one presented in this article, can also be very useful both in other branches of industry as well as in the research area. It seems that may successfully applied in metallurgy Salek and Klimecka-Tatar, 2016), materials science (Korzekwa et al, 2014;Ulewicz and Novy, 2016;Korzekwa et al, 2018), chemistry (Ulewicz and Radzyminska-Lenarcik, 2014;Ulewicz and Radzyminska-Lenarcik, 2015), machining (Radek et al, 2017a;Radek et al, 2017b;Pietraszek et al, 2017;Radek et al, 2018), even supported by an image analysis methods (Gadek et al, 2006;Gadek-Moszczak, 2017;Gadek-Moszczak and Matusiewicz, 2017), and especially in very environment-sensitive biotechnology (Skrzypczak- Pietraszek, 2016;Skrzypczak-Pietraszek et al, 2018a;Skrzypczak-Pietraszek et al, 2018b). It would be very interesting to include a fuzzy description of the problem (Fabis-Domagala et al, 2018;Filo et al, 2018), which allows you to express uncertainty about the process.…”
