Understanding How Social Network Analysis Can Provide Insights Into Emergent Networks of Systems

摘要

The Department of Defense (DoD) is currently faced with a major challenge as individually designed and procured systems become more interoper-able and dependent upon each other to provide value to the warfighter. The DoD currently has 79 Major Defense Acquisitions Programs (MDAP) in addition to the thousands of smaller programs and legacy systems that all operate on the battlefield together. DoD Systems engineers must understand how these systems interoperate on the battlefield to deliver the desired effects for the warfighter. However, tradi-tional systems engineering and system of systems analysis tools and methods are inadequate to describe, visualize, and analyze the complex network of systems that have emerged over the past several decades. There is an opportunity to apply and adapt social network analysis (SNA) tools and methods to systems to understand the network, quantify the "ilities," and anticipate the effect of changes to the network. This chapter examines systems engineering, systems architecture, and systems of systems (SoS) analysis to identify shortfalls in the method to deal with emergent networks of systems. It proposes a combination of individual system architectures to develop the network of systems. It goes on to understand how SNA tools and methods can be adapted to understand networks of systems and identify the potential for the quantification of some of the systems engineering "ilities" through SNA metrics. Finally, it discusses a proposed research path forward to further apply these tools to a more robust representation of the DoD network of systems, further analyze the potential application of SNA tools to networks of systems, and a method to validate and verify the results of this work.
