System of Systems analysis and design environment
The boundaries of system design for space systems have changed significantly in the recent years. If it has been sufficient to
provide single well defined products with a dedicated system in the past, the expectations of users shift towards services and
support, with an entire functional chain required to provide these services. A system design needs to take into account various
and partially divergent functions, to be implemented with space systems, processing and coordination functions on ground and
service provision for the end user – who is not primarily interested in how a service is being established.
This contextual approach requires integrating individual systems originally designed for specific purposes, in order to get an
optimal synergy between these elements. Examples are Earth Observation systems (geographical context and surveillance
functions), communication networks (with space and ground components) as well as navigation services (with their respective
spatial and potential local increment components). In the extreme we find systems like Global Earth Observation System of
Systems (GEOSS) and the future Human Security SoS. In order to be able to enable a global analysis and trade-off of
parameters, it is required to enhance existing development methods and tools on (individual) system level to make them
suitable to this system of systems.
This activity shall define a methodology for the analysis and design of a system of systems. The required tools shall be
prototyped and demonstrated for a multi-level system such as the combined GMES, Galileo and communication systems.
The methodology needs to address hierarchical analysis approaches, based on proven and demonstrated methods from the
classical system engineering domain. Languages such as UML/SysML and advanced approaches such as the “Virtual
Spacecraft Design” need to be enhanced to be able to capture the increased complexity of such systems. A reference
architecture for such a system shall be established.
Supporting tools need to be prototyped. These tools need to support existing engineering and simulation paradigms as well as
meta-modelling paradigms required for the methods identified above. The explicit support to performance modelling at the
SoS level needs to be enabled with the proposed development, by providing elementary performance analysis blocks for the
individual systems.
Deliverables:
Three main types of deliverables are expected form this activity:
1) A well documented methodology for the analysis and design of a system of systems, addressing performance issues:
Formal methods for system-level design and verification; Reference architecture.
2) A support environment for this methodology, to establish relevant system and performance budgets and provide the
elements for system-level trade-offs: System-level performance model building blocks; Architectural design tool for complex
systems; ... .
3) A demonstration prototype for an identified reference system.
