A hybrid FMEA-SD approach for behavioral analysis of factors affecting safety management and incidents in the pelletizing industry

This study aimed to analyze the behavior of effective factors on safety management to reduce incidents in the pelletizing industry using FMEA and the system dynamics approach. Risk assessment for the Sechahon pelletizing plant was performed using the FMEA method. A total of 625 risks were identified, of which 286 are high-risk RPNs and need to be scrutinized. These risks were categorized according to their nature into five categories of physical, exposure to dust, ergonomics, emergencies, and psychosocial risks. The results of our study show that decreasing the number of incidents in "risk reduction scenario" leads to the reduction of risk at the early durations of the study. Hence it is a high-priority policy in comparison with others. The technology improvement scenario shows an incremental growth trend, but the current situation scenario can decrease the number of incidents.
