  This article covers the problem of processing of Big Data that describe
process of complex networks and network systems operation. It also introduces
the notion of hierarchical network systems combination into associations and
conglomerates alongside with complex networks combination into multiplexes. The
analysis is provided for methods of global network structures study depending
on the purpose of the research. Also the main types of information flows in
complex hierarchical network systems being the basic components of associations
and conglomerates are covered. Approaches are proposed for creation of
efficient computing environments, distributed computations organization and
information processing methods parallelization at different levels of system
hierarchy.
