  Engineering networks fall into the category of large-scale networks with
heterogeneous nodes such as sources and sinks. The survivability analysis of
such networks requires the analysis of the connectivity of the network
components for every possible combination of faults to determine a network
response to each combination of faults. From the computational complexity point
of view, the problem belongs to the class of exponential time problems at
least. Partially, the problem complexity can be reduced by mapping the initial
topology of a complex large-scale network with multiple sources and multiple
sinks onto a set of smaller sub-topologies with multiple sources and a single
sink connected to the network of sources by a single link. In this paper, the
mapping procedure is applied to the Florida power grid.
