Abstract

Safety assurance and certification are amongst the most expensive and time-consuming tasks in the development of safety-critical embedded systems. The increasing complexity and size of this kind of systems combined with the growing market demand requires the industry to implement a coherent reuse strategy. A major problem arises as typically a safety-critical product and accompanying safety evidence is monolithic, based on the whole product, and evolutions to the product become costly and time consuming because they entail regenerating the entire evidence-set.

 

Another key difficulty appears when trying to reuse products from one application domain in another, because they are constrained by different standards and the full safety assurance certification process is applied as for a new product, thus reducing the return on investment of such reuse decision. Further, market trends strongly suggest that many future safety-critical systems will be comprised of heterogeneous, dynamic coalitions of systems of systems . As such, they will have to be built and assessed according to numerous standards and regulations. Current certification practices will be prohibitively costly to apply to this kind of systems.

OPENCOSS will devise a common certification framework that spans different vertical markets for railway, avionics and automotive industries, and establishes an open-source safety certification infrastructure. The infrastructure will be realised as a tightly integrated solution, supporting interoperability with existing development and assurance tools. OPENCOSS project proposes an ambitious work agenda that poises to make a significant and long-lasting impact on the way safety-critical embedded systems are certified and put into operation.
