Technique of precise order preference for multiple risk assessment in occupational health and safety: Industrial case study

Risk assessment in manufacturing, construction or service systems are very important tools for ensuring occupational health and safety. Many risk assessment approaches have been proposed in the literature, each with its advantages and disadvantages. In the literature, the authors attempt to develop methods to overcome some of these disadvantages. Different risk priority orders can be obtained for the same failure types with the developed and traditional approaches, and the results may be inconsistent. Hence, different methods produce inconsistent risk ranking outcomes for the same risk assessment problem. This causes confusion for decision-makers when deciding the most-risky failure modes. In this study, the application of the Technique of Precise Order Preference (TPOP) for risk assessment in the field of occupational health and safety (OHS) is conducted to fill the gap in the literature concerning the problem in question and to solve the ranking inconsistency problem related to occupational health and safety. The results of this study show that the advantages obtained from different methods can be combined and a favorable risk priority order can be acquired for decision-makers.
