Application software development for safety instrumented systems - A comparison and evaluation of applied approaches in light of IEC 61511
Gul, Zeba (Master thesis, 2015)Standards are used widely to provide guidance for the development of safety instrumented system. However, safety systems, implemented in railways, aviation, nuclear, etc., also require the development of a safety case to ... -
Evaluating approaches for hazard identification for the inclusion in a safety assessment framework for efficient transport
Skogvang, Øystein; Opsahl, Reidun Kristine; Solibakke, Sindre; Karpati, Peter; Hauge, André A; Sivertsen, Terje; Gran, Bjørn Axel; Lundteigen, Mary Ann (Chapter, 2018)This paper presents the experiences from applying hazard and operability analysis (HAZOP) as support for establishing the safety requirements specification of a new safety-related railway application. The new railway ... -
Evaluating models for the inclusion in a safety assessment framework for efficient transport
Karpati, Peter; Hauge, André A; Sivertsen, Terje; Gran, Bjørn Axel (Chapter, 2018)This paper presents the experiences from applying SysML models as support for establishing the safety requirements specification of a new safety-related railway application. The new railway application is a software-based ... -
The use of Bayesian Belief Networks for combining disparate sources of information in the safety assessment of software based systems
Gran, Bjørn Axel (Dr. ingeniøravhandling, 0809-103X; 2002:35, Doctoral thesis, 2002)The objective of the research has been to investigate the possibility to transfer the requirements of a software safety standard into Bayesian belief networks (BBNs). The BBN methodology has mainly been developed and applied ...
