  Modeling and Simulation (M&S) is finding increasing application in
development and testing of command and control systems comprised of
information-intensive component systems. Achieving interoperability is one of
the chief System of Systems (SoS) engineering objectives in the development of
command and control (C2) capabilities for joint and coalition warfare. In this
paper, we apply an SoS perspective on the integration of M&S with such systems.
We employ recently developed interoperability concepts based on linguistic
categories along with the Discrete Event System Specification (DEVS) formalism
to implement a standard for interoperability. We will show how the developed
standard is implemented in DEVS/SOA net-centric modeling and simulation
framework that uses XML-based Service Oriented Architecture (SOA). We will
discuss the simulator interfaces and the design issues in their implementation
in DEVS/SOA. We will illustrate the application of DEVS/SOA in a multi-agent
test instrumentation system that is deployable as a SOA.
