This page gives a brief introduction into the conceptual design methodology used by the SSDW.
Let's first take a closer look at the
basics of conceptual system design. This will help to
understand the contextual problems associated with the conceptual design process:
- Fuzzy mission and system requriements at the beginning of the design project make
"clean-cut" solutions impossible
- Mission and system elements are strongly interdependent (network-type problem)
- Most important project decisions are made at the beginning, which then are driving
the cost, schedule and risk associated with the mission throughout its lifetime
- Conceptual design results are crucial for "stop/go" decisions
From these basic statements, the
requirements for a conceptual design methodology can be deduced. It should:
- Cover analysis, design, simulation and evaluation
- Implement multidisciplinary elements
- Enable a heuristic, non-sequential approach using baseline concepts and interactive
iteration techniques
- Provide adapted computer tools to support rapid conceptual design in a coherent environment
These requirements result in the main
objectives of the SSDW:
- Allow for conceptual design and optimization studies for space stations and platforms
within a few days, performed by a small design team
- Allow for realistic education in systems engineering by providing easy-to-use tools and
offering design workshops for hands-on experience
- Support space station utilization with respect to overall system questions and through
assessment of experiment specific boundary conditions
One advantage of this approach is that
synergisms on the system- and subsystem level can be
modeled and thus put to use in the design.
