Functional Modeling of an Industrial System

Abstract

In steelworks, due to the complex nature of operations, systems, procedures and methods always involve a certain amount of risk. It is not possible to eliminate all hazards, so the goal is to eliminate and/or control high and critical potential hazards and reduce the rest of the hazards to the lowest reasonable risk level in order to protect workers and equipment against damage and to ensure the proper functioning of the production chain. Risk assessment involves identifying and analyzing the hazards, the sequences of events leading to the hazards, and the risk of hazardous events. The objective of this work is the functional modeling of steelworks of the steel complex of EL-MILIA JIJEL (ALGERIAN QATARI STEEL) and the application of risk analysis methods (STPA, D-Higraph) to identify, analyze the dangers and recommend the necessary control measures for them.
