Data-theoretic methodology and computational platform to quantify organizational factors in socio-technical risk analysis

GIS‐Based Integration of Social Vulnerability and Level 3 Probabilistic Risk Assessment to Advance Emergency Preparedness, Planning, and Response for Severe Nuclear Power Plant Accidents

“…Lack of explicit incorporation of social factors in PRA may lead to (a) underestimating risk due to inadequate quantification of common cause failures (CCFs) (Sakurahara et al, 2017) and dependencies associated with shared organizational and social failure mechanisms, (b) inadequate risk management due to a lack of understanding of the underlying social risk contributing factors and their causal paths of influence on system risk, and (c) inefficient resource allocation due to lack of risk importance ranking of social factors. There are two key requirements for explicit incorporation of social factors into PRA: (i) the integration of a theoretical model of how socio-technical systems perform, considering causal factors with their corresponding level of analysis and relational links, and (ii) the adaptation of appropriate methodological techniques capable of capturing complex interactions of causal factors within their possible ranges of variability and across different levels of analysis to quantify the theoretical framework (Mohaghegh & Mosleh, 2009a;Pence et al, 2017). This section focuses on the development of the theoretical causal framework, and Section 3 introduces the methodology.…”

“…For many years, the explicit incorporation of underlying social and organizational failure mechanisms into Level 1 PRA has been a challenging area of research (Bier, 1999;Ghosh & Apostolakis, 2005;Mohaghegh & Mosleh, 2009a;Pence et al, , 2017. The Socio-Technical Risk Analysis (So-TeRiA) framework (Mohaghegh, 2007;Mohaghegh & Mosleh, 2006, 2009a (Fig.…”

“…This article is part of a line of research by the authors to explicitly incorporate location‐specific social contributing factors into Level 3 PRA (Miller, ; Miller, Pence, Mohaghegh, Whitacre, & Kee, ). There have been significant studies, by several authors of this article, regarding the explicit incorporation of social and organizational factors into Level 1 PRA (Mohaghegh, Kazemi, & Mosleh, ; Mohaghegh & Mosleh, , ; Pence et al., , ). The goal of this study is to initiate the same paradigm of research for Level 3 PRA.…”
