Abstract: The paper considers new classes of spaces of finite, bounded, measurable multisets with different metrics, pseudometrics, quasimetrics, symmetrics, and some properties of these metrics. We discuss the possibilities to apply new types of metrics for estimating proximity of objects with many numerical and/or verbal attributes. We use the introduced indexes of similarity and dissimilarity of objects represented as multisets in new methods of group multiple criteria decision making.
Keywords: Multiset, space of multisets, metric, pseudometric, quasimetric, symmetric, multi-attribute objects, similarity and dissimilarity of objects, group multiple criteria decision making, group verbal decision analysis
