Written by leading system scientists and technology creators, it introduces state-of-the-art concepts of and methodologies for systems approaches towards SoS as well as their practical applications, discussing the planning, design and management challenges in their implementation and the potential impact on societies and the environment. The volume will be of interest to systems engineers, system integrators, and researchers in related engineering fields, as well as government policymakers.
