Design of a fuzzy model that integrates hygiene, safety, and environment systems for the assessment of the overall risk of machines

Abstract

The hygiene, safety, and environment risk assessment is becoming a major challenge for companies in the area of security. It constitutes a precondition in the definition of the strategy to be adopted. The vagueness, uncertainty of input parameters, disputes over opinions between decision-makers, and the absence of integrated models of overall hygiene, safety, and environment risk assessment constitute a handicap in the assessment of risks’ acceptability. In this article, we propose an integrated model based on fuzzy logic to assess the overall hygiene, safety, and environment risk of machines. This model allows to organize the machines into hierarchy, to put in order management systems according to priority of each machine, and to classify the actions to be implemented by priority within each system. The proposed model is performed in a fuzzy logic toolbox of MATLAB using Mamdani algorithm. A case study is carried out in the Mineral Waters of Oulmes company in order to test the proposed model. A comparison shows that the proposed model offers more accurate, precise, and best results than those of classical methods.
