A consistent central design model which covers several distinct engineering disciplines such as a CAD-model (for/from construction in 3-D), a continuum mechanics model (from/for stress analysis), a fluid mechanics model (from/for flow analysis), a control model (from/for control design) and so on may be achieved by using graph-based design languages. In this work, the generation of a consistent central model for the multi-disciplinary analysis of an aircraft cabin has been shown. The analysis included the generation of the class layout (seats, lavatories and so on) and showed the integration of several routes of a power and an information network. The routing algorithm guarantees a shortest path search and includes collision testing. Two alternative networks with a different infrastructure for power and information distribution were automatically constructed through compilation of the design language in a design compiler. As a result, the two network quantities total weight and total network cable length were selected as performance measures for the comparison of the two generated aircraft designs. By extending this approach in the future, the Pareto surfaces of competing aircraft cabin architectures can be automatically constructed, thus serving the cabin architect as a solid guideline for a justified decision making in complex future multi-disciplinary aircraft cabin design scenarios.
