Özet:

This study proposed a new type of error and impact analysis (HTEA) model for assessing work safety risks. According to the classical HTEA, the risk priority numbers (ROS) are calculated by matching the probability, severity and noticeability points. However, the RÖS values created by the classic HTEA have been subject to heavy criticism in literature. This study suggests a new Multi-Critical Decision Making (MCC) model to overcome the disadvantages of the classic HTEA. The recommended risk assessment model combines the full consistency method (FUCOM) and the line theory-matris approach (CTMY) in a foolish environment. The FUCOM method is used to obtain the risk points of the error types and the weight of the risk factors. On the other hand, the RÖS value of each error mode is calculated using a foolish CTMY. It takes into account all possible interactions between risk factors and thus produces more accurate rankings. The foolish assessments of decision makers have been collected using the smallest square distance method. The suggested model is applied in a case study in real life and the error modes are ranked.
