Computer-based system modelling for reliability and safety analysis
This paper presents a methodology to model and monitor system performance and to compare this performance with reliability or safety requirements. The methodology adopted is that of the STARS project (Software Toolkit for Advanced Reliability and Safety analysis) to model complex industrial plant. Three different models (the structural model, the functional model and the behavioural model) describe all the information related to the layout and hardware structure of the system, the behaviour of its components and the functions that they perform. The models support automatic failure mode and effect analysis, fault tree and event tree construction. The construction of the models is fully supported by the software, from a library of standard components. The user can also add further components or component types to a library, or modify and introduce further data. Whenever the plant configuration or usage is altered, a revised safety analysis can be carried out quickly and easily in parallel with the design of the new configuration. The semi-automatic safety analyses therefore will reduce the need for time-consuming and error-prone manual handling of information and improve the consistency and robustness of the analysis.
