Risk Characterization Model & Visualization System in Aluminum Production

Abstract

Abstract The electrolytic aluminum operation accidents have caused great losses to the country and people. Therefore, taking two typical accidents of explosion and leakage in electrolytic aluminum production as the research object, the form of accident risk characterization was explored and a risk characterization visualization system was designed. Based on the methods of risk assessment and characterization, the likelihood and the consequence of the accident were studied. The influencing factors of likelihood and a kind of Euclidean distance formula were used to characterize the likelihood. The consequence portion was characterized by two components, with one being the failure degree determined by the accident and the other being the exposure degree of people and equipment. The intensity of event was used to characterize the failure degree and the spatial search model was used to characterize the exposure degree. Finally, the visual system of electrolytic aluminum operation accidents was established that based on the risk characterization model.
