“…In spite of the HRA methods and topics, expansive studies have been conducted on PSF frameworks in specific domains, including NPP (Ekanem et al, 2016;Groth & Mosleh, 2012; J. W. Kim & Jung, 2003; J. Kim & Park, 2012; A. R. Kim et al, 2016;Lee et al, 2011;Liu et al, 2016;etc. ), industrial maintenance (Franciosi, Pasquale, Iannone, & Miranda, 2019), navigation (Gould, Røed, Koefoed, Bridger, & Moen, 2006), radiotherapy (Pandya, Podofillini, Emert, Lomax, & Dang, 2018), surgery (Onofrio & Trucco, 2018), offshore structures (Bea, 2000), marine (Xi & Hu, 2012), spaceflight (Mindock & Klaus, 2011 Among the various studies on PSF hierarchy, four have been highlighted and are considered worth reviewing in detail: J. W. Kim and Jung (2003), Groth and Mosleh (2012), Liu et al (2016), and Pandya et al (2018). Table 3 summarizes the main process of taxonomy establishment and the final PSF hierarchies.…”
