“…For example, in [35] authors proposed a new accident causation theory based on STAMP and on a risk management framework to go beyond human, organizational and technological characteristics encompassing sociological factors (legislative, regulatory, and cultural). While STAMP and its related tools have a purely qualitative nature, other research is aimed at their integration with risk and losses quantification methods, e.g., [36]. A shared solution relies on the usage of model checking techniques to improve or verify system requirements against their actual configuration [37], [38], to guide prioritization of hazardous scenarios highlighted by the STPA analysis [39], or to perform a safety assessment providing a formal and unambiguous representation of the system and its related threats [40].…”

The interaction between the physical world and information technologies creates advantages and novel emerging threats. Cyber-physical systems (CPSs) result vulnerable to cyber-related disruptive scenarios, and, for some critical systems, cyber failures may have fallouts on society and environment. Traditional risk analysis in no more sufficient to deal with these problems. New techniques are gaining increasing consensus, especially those based on systems theory. In this context, the System-Theoretic Process Analysis for Security (STPA-Sec) extends the Systems-Theoretic Accident Modelling and Processes (STAMP) model considering cyber threats, and identifying unsafe and unsecure controls throughout a cyber socio-technical system. Despite its large usage as a descriptive tool, there is still limited use of STPA-Sec in (semi-)quantitative terms. This article presents System-Theoretic Process Analysis for Security with Simulations (STPA-Sec/S), a methodological interface between STPA-Sec and quantitative resilience assessment based on simulation models. The methodology is instantiated in a demonstrative case study of a water treatment plant, and its critical CPSs which may impact both community health, and environment. The obtained results show how STPA-Sec/S foster systems understanding, allow a systematic identification of its major criticalities, and the respective quantification.INDEX TERMS Cyber security, cyber-socio-technical systems, hazard analysis, industrial systems engineering, resilience management, systems modeling.Open Access funding provided by 'Università degli Studi di Roma ''La Sapienza''' within the CRUI CARE Agreement

It is important to evaluate the risks in industrial parks and their processes due to the consequences of major accidents and especially the domino effect. Scientific works present a wide possibility of models to deal with these situations. In this work, based on the information extracted from the scientific literature, six groups of risk methodologies are defined, analyzed, and characterized with methods that cover the standards, preventive, probabilistic, traditional, modern, and dynamic evaluation that are applied or could be used in industrial parks. It also tries to achieve the objective of determining which are more appropriate if the possible situations and causes that can produce an accident are taken into account, identifying and evaluating them with characteristics of simultaneity and immediacy, determining the probability of an accident occurring with sufficient advance in time to avoid it under the use of a working operational procedure. There is no definitive methodology, and it is necessary that they complement each other, but considering the proposed objective, the integrated application of traditional methodologies together with the management of safety barriers, the dynamic evaluation of risks, and the inclusion of machine learning systems could fulfill the proposed objective.

“…component interaction). By these methods, a complex system is treated as a complete body, and causal factors are analyzed from all levels, and the relationship between system components are clarified, shedding new lights on the safety analysis of complex systems [15][16][17]. The results of these methods could be validated by simulation with models like hose-drogue model [5] and auxiliary model [6,18,19].…”

This paper aims to identify the main cause of the hose whipping phenomenon (HWP) in air refueling, and come up with effective preventive measures. The system-theoretic accident model and process (STAMP), i.e., the system-theoretic process analysis (STPA), was adopted to evaluate the safety of air refueling. Then, the evaluation results were verified with a self-designed simulation validation model. The results show that the HWP is controlled by the docking speed, reel mechanism, and designed hose length; the swing range and tension change of the hose increased under inappropriate speed control; reel control could end the hazardous state of the hose within 50s after docking; the HWP occurred after the hose length was shortened from 22m to 14m. The research findings provide a reference for the prevention of the HWP.
