Assessing and Ranking Health, Safety and Environmental Risks Through Analytical Network Process (ANP) Method in Cement Plant in 2020

Abstract

In today's competitive world, decision-making and management are based on risk assessment. Accordingly, the present study deals with assessing and managing the risks of Health , Safety and Environment (HSE) aspects in cement factory through combining three widely used methods including FMEA, William and Fine, and EFMEA to determine and estimate the level of risk, and to control and mitigate this risk using analytical network process (ANP) method. In this research, three ANP models were used for risk assessment methods of William & Fine, FMEA, and EFMEA. Then, paired comparisons of risks were performed through (ANP) in each set and provided to experts. In this study, overall for five general departments (materials milling, cement mill, stone crusher, baking, and loading house departments) 1184 risks were identified. Regarding assessment of health risks, 352 risks were identified; the maximum level of risk was associated with Noise from the cement mill department. Considering assessment of safety risks, 529 risks were identified which the maximum risk was related to: falling from cement mill department (0.0601). Finally, with regards to the environmental risk assessment, 303 risks were detected, where the maximum risk was related to Reduction of resources and energy in the cement mill (0.064). The combination of the risk assessment methods including William & Fine, FMEA, and EFMEA as well as simultaneous application of multi-criterion decision-making methods (MCDM) in particular ANP, is an efficient model in real assessment of levels of HSE risks ,So that they perfectly complement each other.
