“…Organizational feedback control loop: In order to apply STPA for initiating organizational hazard analysis, as the main reason of this paper, it is needed to use a specific version of the feedback control loop that was exclusively developed for deficiency analysis of organizational safety control mechanisms. Figure 3 presents thisspecific Organizational Feedback Control Loop to gether with its customized Process Model [21]. Based on Figure 3, five requirements shall be met to accurately enforce the Control Actions by organizational control components: a.…”

“…For example, organizational variables and goals are not as clear as the technical variables. Furthermore, feedback and actuator channels in organizational control loops are forms and formal requests or reports; instead of signals or other technical tools that usually are used in technical loops [21].…”

ICAO recent manuals for both State Safety Policy (SSP) and Safety Management System (SMS) explicitly concentrate on the organizational roots of accidents. The Safety Risk Management (SRM) system, as the core component of both SSP and SMS, consequently are expected to manage the organizational safety risk. In view of that, this paper present a new risk analysis framework that can be feasible to apply as the analyzing logic of the formal SRM; especially, in the start line of the risk management process. For this reason, the framework is founded on the System Theoretic Process Analysis (STPA) to cope with the sociotechnical feature of aviation organization. To apply STPA as the base of the framework, a customized "Feedback Control Loop" is applied to model organizational control mechanisms and extracts their hidden hazards. Furthermore, an innovative concept and procedure are introduced for "Hazard Activation Likelihood" estimation and "HazardConsequences"analysis.

While strengths can be improved, when weaknesses are not addressed, the desired improvements are not achievable. Determining weaknesses and strengths is much more important when it comes to safety issues in critical industrial units. Oil, gas and petrochemical industry is the main pillar of the economy in Iran. Not only most of the oil, gas and petrochemical infrastructure in Iran are old and worn-out, but also the safety management practices are not adequate. Resilience engineering is a growing concept toward proactive and preventive safety and performance improvement in critical industrial units. This study presents a new algorithm for performance evaluation of resilience engineering culture in critical industrial units. A petrochemical plant is considered as a real-life case study to demonstrate the application of the proposed methodology. The presented algorithm is based on graph theory, statistical methods, and matrix algebra which offer some desirable properties for modeling and solving complex decision-making problems and considers the interactions between factors. To the best of our knowledge, this is the first study that proposes a performance evaluation algorithm based on graph theory and matrix approach.
