Application of Functional Resonance Analysis Method and System-Theoretic Accident Model and Processes approaches combined with other methods

Abstract

When dealing with risks associated with complex sociotechnical systems, one needs to employ approaches that will make it possible to better understand the systems' complexity and analyze them more efficiently. Several approaches have been proposed and in the recent literature, the System-Theoretic Accident Model and Processes (STAMP) and Functional Resonance Analysis Method (FRAM) stand out. These have been applied both separately and integrated with other methods for risk analysis. This study aims to provide an overview of the literature related to the application of FRAM and STAMP integrated with other methods. Papers from various scientific resources, including Scopus, IEEE, Compendex and INSPEC, Google Scholar, and Espace ÉTS from 2004 to 2021, in English, were consulted. The keywords used to narrow our search were FRAM, STAMP, STPA, and risk analysis. The results show that FRAM and STAMP have been used in combination with other methods such as fuzzy logic, Monte Carlo Simulation, bow tie, and model checking. Their combination with other methods has enhanced their efficiency and capability in risk analysis and provides better and more precise outcomes for some specific contexts of study. These combined proposed approaches have been applied and validated for specific contexts in specific studies. Therefore, the generalization and validation of the combined methods in different contexts could be an outlook for future studies.
