The crisis of risk analysis in complex socio-technical systems a literature review Part A: Dependency between common risk analysis methods and obsolete accident models

Background and aims High risk organizations and industries such as oil and gas extraction¡ chemical and petrochemical industries¡ nuclear and aerospace industries and air traffic control organization¡ in addition to use of advanced technology¡ have complex social aspects as well. Recent studies have shown that the combination of advanced technology and social vague rules of such organizations¡ forming a complex system that encounter with a new type of risk. The type of risk that inaccessible to conventional risk analysis approaches.Therefore¡ in this paper¡ with comprehensive review of recent studies¡ the ineffectiveness of traditional risk analysis methods in complex socio-technical systems will prove and the roots of this inefficiency will analyze.
Results and The ineffectiveness of traditional risk analysis methods in complex socio-technical systems¡ rooted in the inefficiencies of out of date accident models and theories that have shaped the theoretical field of these method. Because¡ intrinsic conditions in such complex systems¡ and accident formation mechanism on it¡ basically different with what conventional models assume.
