Abstract

Presented is a model-driven development method for avionics systems comprising of a domainspecific model, mathematical optimization, and an attached network simulation. For Integrated Modular Avionics (IMA) the degree of freedom in choosing the system architecture is so high that determining the optimum by hand is hardly possible for large aircraft. A domain-specific model was created with the Eclipse Modeling Framework (EMF) holding system requirements and architecture variants, such that it can automatically be validated and evaluated. Moreover, combinatorial optimization is used to determine optimal architectures by algorithm for single and multiple objectives. Optimization on civil aircraft and a space launcher revealed improvements of up to 30% in single design objectives. Moreover, the architecture model can automatically be converted in configuration stubs and an AFDX network simulation.
