Incorporating certification in feature modelling of an unmanned aerial vehicle product line

Safety critical systems (e.g., an avionics control system for safe flight) are often required to achieve certification under pre-established standards (e.g., DO-178B for software considerations in airborne systems and equipment certification). We have been working with our industrial partner for the last three years to develop product line assets for their avionics software product line (SPL) and, recently, we encountered two major challenges regarding certification. Firstly, an individual product must be certified, but each may require a different certification level: there might be variations in the certification requirements according to specific system usage contexts. Secondly, certification involves not only product but also process, as standards such as DO-178B also assess the quality of the development process. In this paper, we propose to include a certification view during feature modelling to provide a better understanding of the relationships between features and a certification level required for each product. The experience of introducing certification into the design model of an Unmanned Aerial Vehicle (UAV) SPL is presented to illustrate some key ideas. We also describe the lessons we have learned from this experience

Adapting a software product line engineering process for certifying safety critical embedded systems

Software Product Line Engineering (SPLE) is a software development paradigm that aims at reducing the development effort and shorting time-to-market through systematic software reuse. While this paradigm has been successfully applied for the development of embedded systems in various domains, new challenges have emerged from the development of safety critical systems that require certification against a specific standard. Existing SPLE approaches do not explicitly consider the various certification standards or levels that products should satisfy. In this paper, we focus on several practical issues involved in the SPLE process, establishing an infrastructure of a product line engineering for certified products. A metamodel is proposed to capture the entities involved in SPL certification and the relationships among them. ProLiCES, which is a model-driven process for the development of SPLs, was modified to serve as an example of our approach, in the context of the UAV (Unmanned Aerial Vehicle) domain
