The 17th Symposium on Operations Research was held at Universität der Bundeswehr Hamburg, August 25-28, 1992, as the annual meeting of the Gesellschaft für Mathematik, Ökonomie und Operations Research (GMÖOR). The aim of this book is to provide a timely and comprehensive documentation of the...

The paper investigates Lorenz dominance and generalized Lorenz dominance to compare distributions of economic status in one and several attributes. Restrictions of these dominance relations are developed that focus on central parts of the distributions and facilitate their comparison. Copyright...

A new multivariate approach is introduced to identify the middle class of a society and to measure its possible decline. The middle class is a properly defined central region in attribute space that contains a fixed portion of the population. The decline of the middle class is measured by...

In this paper we investigate a new class of central regions for probability distributions on Rd, called weighted-mean regions. Their restrictions to an empirical distribution are the weighted-mean trimmed regions investigated by Dyckerhoff and Mosler (2011) for d-variate data. Furthermore a new...
