  In this report, we investigate (element-based) inconsistency measures for
multisets of business rule bases. Currently, related works allow to assess
individual rule bases, however, as companies might encounter thousands of such
instances daily, studying not only individual rule bases separately, but rather
also their interrelations becomes necessary, especially in regard to
determining suitable re-modelling strategies. We therefore present an approach
to induce multiset-measures from arbitrary (traditional) inconsistency
measures, propose new rationality postulates for a multiset use-case, and
investigate the complexity of various aspects regarding multi-rule base
inconsistency measurement.
