基于DEMATEL-ISM方法的水电站机组检修作业安全事故致因链分析
Analysis of safety accident causation chain in hydropower station maintenance operations based on DEMATEL-ISM method
摘要
Abstract
Aiming at the problems of diversified maintenance operations,numerous risk factors,and frequent safety accidents in hydropower station units,the safety factors affecting the maintenance operations of hydropower station units are classified through literature mining and expert interviews.Based on the DEMATEL-ISM method,a multi-level hierarchical ISM model of safety accident causes was constructed to determine the level of accident causes.By analyzing the centrality and weight of accident causes,mining the key causal factors and deriving the path weights of the accident causal chain,the key causal chain was determined.The model was used to analyze the key causal chain of a hydropower station as an example.The results show that inadequate safety inspections are the key cause factor,and the key causation chain is inadequate safety inspections→illegal operations→equipment problems→dusts,paints,and other harmful substances.关键词
