Abstract
A
IRCRAFT DEVELOPERS, like other development and manufacturing companies,
are experiencing increasing complexity in their products and growing competition in the
global market. One way to confront the challenges is to make the development process
more efficient and to shorten time to market for new products/variants by using design
and development methods based on models. Model Based Systems Engineering
(MBSE) is introduced to, in a structured way, support engineers with aids and rules in
order to engineer systems in a new way.
In this thesis, model based strategies for aircraft and avionics development are stud-
ied. A background to avionics architectures and in particular Integrated Modular Avion-
ics is described. The integrating discipline Systems Engineering, MBSE and applicable
standards are also described. A survey on available and emerging modeling techniques
and tools, such as Hosted Simulation, is presented and Modeling Domains are defined
in order to analyze the engineering environment with all its vital parts to support an
MBSE approach.
Time and money may be saved by using modeling techniques that enable under-
standing of the engineering problem, state-of-the-art analysis and team communication,
with preserved or increased quality and sense of control. Dynamic simulation is an ac-
tivity increasingly used in aerospace, for several reasons; to prove the product concept,
to validate stated requirements, and to verify the final implementation. Simulation is
also used for end-user training, with specialized training simulators, but with the same
underlying models. As models grow in complexity, and the set of simulation platforms
is expanded, new needs for specification, model building and configuration support
arise, which requires a modeling framework to be efficient.

Acknowledgments
T
HE WORK PRESENTED in this thesis has been carried out at the Division of Ma-
chine Design in the Department of Management and Engineering (IEI) at Linköping
University (LiU), Sweden.

There are several people I would like to thank for their support and advice during the
work; first I want to thank my supervisor, Professor Petter Krus, for his guidance and
support. The most interesting and encouraging work during the period was when we
performed the ModuLiTH (Modular Electric Vehicle) project course.

I want to thank my industrial sponsors and supervisors at Saab Aerosystems: Anders
Pettersson who initiated the idea of starting a research project, Stefan Andersson who
got me deeply involved in the MBSE program at Saab Aerosystems and Erik Herzog for
his academic view and an interesting time together in the SPEEDS project.

At Machine Design in Linköping University I also want to thank Olof Johansson for
encouraging support and cooperation in the NFFP project, and also Björn Lundén for
his introduction to research and studies at the graduate level. For pleasant teamwork
with papers, presentations and discussions in the MBSE area at Saab Aerosystems and
at the Division of Machine Design, there are several people I am grateful to, among
whom I would here like to mention; Bengt-Göran Sundqvist, Johan Ölvander, Anders
Weitman, Sören Steinkellner, Hampus Gavel, Gert Johansson, Lars Karlsson, Ingela
Lind and Ulrik Pettersson.

The work has been financially supported by the ProViking research program (con-
nected to the Swedish Foundation for Strategic Research), NFFP (National Aviation
Engineering Research Program) and Saab Research Council.
