Zusammenfassung
The paper considers techniques for grouping objects that are described with many quantitative and qualitative attributes and may exist in several copies. Such multi-attribute objects may be represented as multisets or sets with repeating elements. Multiset characteristics and operations under an arbitrary number of multisets are determined. The various options for the objects' aggregation (addition, union, intersection) and the main features of hierarchical and non hierarchical cluster analysis in multiset metric spaces are discussed.
