Novel Framework Approach for Model-Based Process Integration from Requirements to Verification Demonstrated on a Complex, Cyber-Physical Aircraft System 2018-01-1947

This paper presents a demonstrator developed in the European CleanSky2 project MISSION (Modelling and Simulation Tools for Systems Integration on Aircraft). Its scope is the development towards a seamless integrated, interconnected toolchain enabling more efficient processes with less rework time in todays, highly collaborative aerospace domain design applications.
The demonstration described here, consists of an open, modular and multitool platform implementation, using specific techniques to achieve fully traceable (early stage) requirements verification by virtual testing. The most promising approach is a model based integration along the whole process from requirements definition to the verified, integrated (and certified) system. Extending previous publications in this series, the paper introduces the motivation and briefly describes the technical background and a potential implementation of a workflow suitable for that target. Applying novel methodologies like agility to the aerospace domain workflow requires a sophisticated way of managing the multidimensional integration of various engineering tools and processes usually used along the development cycle. The demonstrator relies on two open standards for connecting databases of the necessary information (models) with each other and expose them to connected tools throughout the process. It is shown that such interconnected information, represented by a common datamodel, allows a high level of automation at various steps within a typical design process and results in more reliable workflows. In this regard, the present paper focusses on the design part from requirements definition, architectural design, systems decomposition up to performance modeling. The early stage verification of the driving product requirements is achieved by model based, virtual testing methods representing incremental maturity levels of the system along the development cycle. Later on, test automation will be integrated as it is already considered from the very beginning in the iterative, agile workflow.
