“…Zhang [3] introduced an evaluation method for elevator faults based on FaHA. Tang et al [4] presented a safety index evaluation method for elevators based on Bayesian networks, addressing the uncertainty in complex electromechanical environments, and enabling maintenance alerts and intelligent responses. Du Ya et al [5] utilized grounded theory and structural equation modeling to analyze the multifaceted risk factors and their mechanisms for elevator safety and performed a comprehensive assessment of elevator safety risk warnings based on the fuzzy evaluation method.…”

In order to excavate the key causes of elevator accidents, 70 elevator accident investigation reports from 2018 to 2023 were collected, and data mining was carried out to extract "4M" unsafe factors. On this basis, based on the complex network, the model of elevator accident causation network is constructed, and the statistical characteristics of this model are analyzed. Finally, the entropy weight-TOPSIS is used to construct a comprehensive evaluation model of network node importance, which comprehensively evaluates the causes of elevator accidents from four indicators, including degree centrality, intermediary centrality, proximity centrality and aggregation coefficient of nodes, and identifies the key factors of elevator accidents. The results show that unsafe factors such as defects of equipment and facilities, illegal operation, improper operation, weak safety awareness, inadequate implementation of safety responsibilities, and inadequate on-site supervision are the key causes of elevator accidents, which need to be controlled and controlled.
