Cost focused optimization os system safety and reliability in the concept phase customer value fro

Purpose and goal

The project has the following aims and goals: - Development of methodology to produce safer and more reliable products at a lower cost. This is achieved since a methodology is developed and tested on an aircraft subsystem. However, the methodology needs to be further developed to be used in a larger scale. - To create a new research area at Linköping University. This has also been achieved but an undergraduate course has not yet been established. - A licentiate degree for an industrial Ph.D. student. This goal is achieved, the licentiate thesis has been presented and approved.

Results and expected effects

The project has resulted in new methodology for optimization of system safety and reliability. This is an academic contribution since papers have been presented that unite these areas in a new way. From an industrial point of view, the effects are yet difficult to assess since the methodology needs to be further developed. A research group has been established at LiU and system safety elements have been introduced in courses for MSc students which give a positive effect for disseminating the area. At Saab, a system safety methodology that is based on a functional view has been developed.

Approach and implementation

The project was preceded by a pre-study (NFFP5-2009-01316) which formed a good ground for further work in this project. The project has been performed with one part at Liu and one part at Saab and an industrial PhD student that has been a link between industry and university. The project has been divided into five work packages which have lead to a clear plan for what to perform at different stages. All milestones have been achieved in time and the schedule has been held.
