“…This method is based on expert linguistic terminology expressions, which need to be converted from fuzzy linguistic terms to definite values to avoid ambiguity and reach a unified opinion. Fuzzy DEMATEL is a multi-indicator decision-making technique, which has the advantage that the decisionmaking process is based on pairwise comparisons and acceptance relationships, and fuzzy DEMATEL is applied to different areas of research, such as risk assessment and safety management [31,32]. In this paper, to solve the fuzzy problem of expert evaluation in the DEMATEL method, the triangular fuzzy numbers in fuzzy theory are introduced, and the initial direct matrix is fuzzified by applying the semantic evaluation and fuzzy number conversion relation of Li [33].…”

In order to effectively reduce the probability of subway operation accidents and explore the key risk factors and multi-factor risk coupling mechanism during the subway operation period, this paper classifies the risk factors affecting subway operation safety into four categories of primary risk factors, personnel, equipment and facilities, environment and safety management, introduces the emergency management concept to identify 18 secondary risk factors, combines the improved fuzzy decision making test and evaluation laboratory (DEMATEL) and Explanatory Structure Model (ISM) to visualize the risk factor action relationship, construct a six-order hierarchical recursive structure model for subway operation accidents, explore the coupling relationship and effect between risk factors from the perspective of single factor, double factor and multiple factors, establish a coupling effect metric model based on Natural Killing Model (N-K), carry out coupling information interaction scenario combination and coupling effect quantification calculation, and finally integrate fuzzy DEMATEL-ISM-NK model to correct the centrality, determine the key risk factors in subway operation accidents from the perspective of macro and micro analysis, qualitative and quantitative research, and propose safety prevention and control strategies accordingly. The results show that six factors, such as emergency management and social environment, are key risk factors to be prevented in the metro operation system. Multi-factor risk coupling leads to a higher probability of subway operation accidents, and controlling multi-factor involvement in coupling is an effective means to reduce the occurrence of subway operation accidents.

“…The transfer of experience and the development of an educational program based on experience-based learning effectively increase people's risk perception and, accordingly, strengthen their reactive approach to workplace events, directly affecting the number and severity of occupational accidents. Yeganeh et al [27] studied the factors affecting workers' risk perception using the DEMATEL method. The study's findings showed that safety knowledge, quality and quantity of safety training, and safety climate had the greatest impact on RP.…”

Underground coal mines, one of the most dangerous work environments, have experienced accidents and disasters. One of the main reasons for those unsafe events is the workers’ poor understanding of the hazards and risks of working in this work environment. Therefore, the present study aims to identify factors affecting the safety risk perception of underground coal mine workers in Iran and investigate their cause-and-effect relationships. By reviewing the literature, 40 variables were identified in five categories: individual, organizational, environmental, task, and external factors. The identified variables were ranked according to the expert group’s opinion in the form of a fuzzy Delphi study regarding their effects on risk perception. In the next step, 23 variables were selected to investigate the cause-and-effect relationships using the DEMATEL method. The study’s findings showed that organizational factors and some individual factors play a fundamental role in workers’ risk perception. The variables of safety culture, safety management style, and safety attitude had the most significant impact, and the variables of personal protective equipment and risk aversion had the smallest impact on workers’ risk perception. The present study’s findings can be used as a guideline to provide effective solutions for managers and workers in improving safety risk perception, subsequently reducing unsafe behaviors and increasing the safety status of underground coal mines.
