"The embedded safety-critical systems design and development industry is facing increasing complexity and variety of systems and devices, coupled with increasing regulatory constraints while costs, performances and time to market are constantly challenged.This has led to a profusion of enablers (new processes, methods and tools), which are neither integrated nor interoperable because they have been developed more or less independently, addressing only a part of the complexity issue, such as safety. The absence of internationally recognized open standards is a limiting factor in terms of industrial performance when com-panies have to select among these enablers.CESAR will bring significant and conclusive innovations in the two most improvable systems engineering disciplines:- Requirements engineering in particular through formalization of multi viewpoint and multi criteria requirements,- Component based engineering applied to design space exploration comprising multi-view/multi-criteria architecture trade-offs.In addition CESAR intends to provide industrial companies with a breakthrough in system development by deploying a customizable systems engineering ‘Reference Technology Plat-form’ (RTP) making it possible to integrate or interoperate existing or emerging available technologies. This will be a significant step forward in terms of industrial performance im-provement that will help to establish de-facto standards and contribute to the standardization effort from a European perspective.Relying on industrial use-cases and scenarios, CESAR is strongly industry driven. It will ad-dress societal safety, mobility and environmental demands from a multi-domain point of view, relying on high maturity inputs (TRL 4) and target high maturity outputs (TRL 6).Quantified objectives are defined in the proposal regarding integration aspects (RTP), processes and product- related aspects."
