Integration of safety requirements in the initial phases of the project life-cycle of hardware/software systems
The research aimed at identifying a methodology and defining a coherent safety life-cycle with respect to the development of systems containing software. In particular, emphasis is placed on the initial life-cycle phases, the ones in which safety problems are generally disregarded due to limited availability of information on product characteristics and due to difficulties in treating the problem from a functional point of view. The methodology was applied to a braking system of a high speed train, and takes into account principles defined in the IEC 1508 draft standard: the methodology includes systems modelling and analysis techniques integrated in the requirements phases and organized in a manner consistent with the standard IEC 1508 in order to derive software system safety requirements.
