The treatise supports understanding the phenomena of complexity in
engineering, distinguishes complexity from other challenges and presents
an overview of definitions and applied approaches.The historical
background of complexity management is explained by highlighting the
important epochs, their key actors and their discoveries, findings and
developments. Knowing about the appearance of early system awareness in
ancient Greece, the creation of mechanical philosophy in the 17th
century and the discovery of classic physics enables the reader to
better comprehend modern system sciences and management approaches.A
classification of complexity management approaches by research fields
indicates current focus areas and starting points for future
discussions. In a comprehensive map, the classification points out
mutual overlaps between engineering disciplines in terms of similar
complexity management approaches.Finally, the treatise introduces a
generic complexity management framework, which is based on structural
management approaches.
