Title: Using MDA for Safety Critical Systems Development: Transformation and Analysis of Integrated Modular Avionics Richard Paige Richard Paige Abstract In the context of building and analysing an IMA system, which is required to undergo safety certification, we compare the use of a transformation language and a general-purpose model management language, for model-based analysis. The comparison highlights challenges with using MDA/MDD for critical systems development, and demonstrates some of the characteristics that are needed in languages used for analysing IMA systems.
