  The paper presents several approaches to generalized blockmodeling of valued
networks, where values of the ties are assumed to be measured on at least
interval scale. The first approach is a straightforward generalization of the
generalized blockmodeling of binary networks (Doreian et al., 2005) to valued
blockmodeling. The second approach is homogeneity blockmodeling. The basic idea
of homogeneity blockmodeling is that the inconsistency of an empirical block
with its ideal block can be measured by within block variability of appropriate
values. New ideal blocks appropriate for blockmodeling of valued networks are
presented together with definitions of their block inconsistencies.
