We restrict this overview to the case n = 1 only. Among several possible approaches to fuzzy quantitative data, mostly fuzzy quantities which are upper semi-continuous normal convex fuzzy subsets of R are discussed and applied. cav_un_auth*0212836 Zittau Fuzzy Colloquium 2001 /9./ Zittau DE 17.09.2001-19.09.2001 BA E http://hdl.handle.net/11104/0130768 UTIA-B 20010149 2001 2001 Zittau IPM Proceedings of the 9th Zittau Fuzzy Colloquium 2001 55 60
