In areas such as military, security, aerospace, and disaster management,
the need for performance optimization and interoperability among
heterogeneous systems is increasingly important. Model-driven
engineering, a paradigm in which the model becomes the actual software,
offers a promising approach toward systems of systems (SoS) engineering.
However, model-driven engineering has largely been unachieved in complex
dynamical systems and netcentric SoS, partly because modeling and
simulation (M&S) frameworks are stove-piped and not designed for SoS
composability. Addressing this gap, Netcentric System of Systems
Engineering with DEVS Unified Process presents a methodology for
realizing the model-driven engineering vision and netcentric SoS using
DEVS Unified Process (DUNIP).
The authors draw on their experience with Discrete Event Systems
Specification (DEVS) formalism, System Entity Structure (SES) theory,
and applying model-driven engineering in the context of a netcentric
SoS. They describe formal model-driven engineering methods for
netcentric M&S using standards-based approaches to develop and test
complex dynamic models with DUNIP. The book is organized into five
sections:
- Section I introduces undergraduate students and novices to the
world of DEVS. It covers systems and SoS M&S as well as DEVS
formalism, software, modeling language, and DUNIP. It also assesses
DUNIP with the requirements of the Department of Defense's (DoD) Open
Unified Technical Framework (OpenUTF) for netcentric Test and
Evaluation (T&E).
- Section II delves into M&S-based systems engineering for graduate
students, advanced practitioners, and industry professionals. It
provides methodologies to apply M&S principles to SoS design and
reviews the development of executable architectures based on a
framework such as the Department of Defense Architecture Framework
(DoDAF). It also describes an approach for building netcentric
knowledge-based contingency-driven systems.
- Section III guides graduate students, advanced DEVS users, and
industry professionals who are interested in building DEVS virtual
machines and netcentric SoS. It discusses modeling standardization,
the deployment of models and simulators in a netcentric environment,
event-driven architectures, and more.
- Section IV explores real-world case studies that realize many of
the concepts defined in the previous chapters.
- Section V outlines the next steps and looks at how the modeling of
netcentric complex adaptive systems can be attempted using DEVS
concepts. It touches on the boundaries of DEVS formalism and the
future work needed to utilize advanced concepts like weak and strong
emergence, self-organization, scale-free systems, run-time modularity,
and event interoperability.
This groundbreaking work details how DUNIP offers a well-structured,
platform-independent methodology for the modeling and simulation of
netcentric system of systems.
