Raytheon’s
One
Architecture/
EMS Strategy
Mission Systems Integration (MSI)
and Mission Assurance are key
components of Raytheon’s growth
strategy. Previous editions of Technology
Today have addressed Raytheon systems
and software technology in support of
Mission Systems Integration 1 . Highlighted
in that issue was the following statement
from Peter Pao 2 , Raytheon’s vice president
of Technology:
“The key to MSI business is systems engineering
capability, especially architecture
and modeling and simulation (M&S). To
this end, I am pleased to announce a fourcolumn
MSI Initiative which focuses on
architecture and modeling and simulation.”
A later edition of Technology Today
focused on, “Achieving Mission Assurance
Through Integrated Systems and Software
Development.” This issue highlighted the
need for world-class architecture development,
modeling and simulation, and
systems engineering in the pursuit of
NoDoubt Mission Assurance 3 .
For this reason, Raytheon has undertaken
an extraordinarily successful effort to integrate
its world-class M&S capabilities under
the banner of Enterprise Modeling and
Simulation (EMS). As shown in Figure 1,
EMS provides foundational support for:
Mission Systems Integration
Mission Assurance

Engineering Perspective
EMS: Leading the revolution in virtual
realization
Since the dawn of human reasoning, abstraction has
been used to model fact. The refinement of geometric
modeling accomplished by the Pythagoreans in Sicily,
circa 300 B.C., provided a detailed explanation of nature
and a precise foundation for classical art, architecture
and masonry. A traceable evolution of abstract modeling
parallels the history of physics and engineering.
With the advent of high-speed computing, abstract
modeling evolved into simulation at ever-increasing levels
of fidelity. Finally, the Internet has caused a revolution
in virtual realization — so much so that modeling
and simulation (M&S) has become a cornerstone of integrated
product development and object-oriented system
engineering.

Modeling and Simulation
Dramatic reduction in cost and risk can be realized by maintaining an M&S baseline
throughout a program’s life. Concept exploration, initiated with process modeling, culminates
with a virtual prototype used for design and development of the actual prototype.
Ultimately, the virtual prototype becomes a system model used for test and evaluation and
is, oftentimes, validated as a requirement for system sell-off. Unfortunately, the system
model can be lost when the program is retired or cancelled due to software complexity and
difficulty of use. Raytheon Enterprise Modeling and Simulation (EMS) is developing the
architecture and open standards to retain and reuse our M&S heritage, assure enterprisewide
desktop access for analysis and demonstration and, ultimately, lead the revolution in
virtual realization.
Raytheon’s ID or fingerprint is represented by M&S. In the natural course of engineering
rigor, Raytheon develops and maintains high fidelity validated C3ISR and weapon system
M&S. In fact, Raytheon regularly contributes high fidelity M&S to prime contractors’ IMAX
quality visualization facilities. However, EMS is taking a different approach to large-scale
mission-level virtual realization. Rather than focus on infotainment, EMS focuses on innovation:
solutions derived from exhaustive assessment of alternatives, high-quality 3-D visualization
of joint battlespace interoperability, mission/systems integration and acquisition confidence.
Exercise Controller (ExCon), a control architecture that was developed for the NASA Space
Station Training Facility, was extended to provide EMS with a framework for simulation
integration and operation. The framework accommodates any middleware architecture and
ensures essential data sharing, spatial/temporal synchronization, and faster-than-real-time
advancement and pause for metric data collection and analysis. Extensive M&S reuse is
realized because minimal recode and minimum adherence to legacy development standards
are required for simulation integration.
This issue features articles associated with the intent, infrastructure, application and operation
of EMS. We are also pleased to introduce a few of the people behind EMS by profiling
some of the engineers who have made key contributions.
We hope you enjoy the material and encourage all engineers, as well as capture, campaign
and program leaders who seek more information and access to the diverse features of
EMS, to visit the website at http://home.ray.com/ems.
