A Multiple Criteria Risk Analysis Model and a Case Study in Metal Industry

Abstract

Healthy workers and appropriate working conditions not only ensure enhancing the quality of life of individuals but also contribute to productivity of workplaces. To reach these benefits, occupational health and safety (OHS) risk management is the key concept for all kinds of organizations. In this study, a multiple criteria risk analysis model is proposed and applied in a workplace operating in the metal industry. The model integrates the Decision Making Trial and Evaluation Laboratory Technique (DEMATEL), the Analytical Network Process (ANP) and the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS). The model provides a scientific approach for risk assessment and suggests a precedence order of the workshops for the risk control stage. The study contributes to the literature by considering the interrelations between risk factors and determining a ranking order in order to put preponderant risks forward with an integrated approach. Furthermore, in the application study, it is considered not only the traditional risk factors but also the psycho-social factors. The findings of the study offer fruitful inspirations to the managers in metal industry and the approach is believed to have a wide range of applications for risk assessment and analysis in the field of OHS.
