摘要
利用层次分析法(AHP)和逼近理想点排序法(TOPSIS),建立了起重设备的风险评估模型,依据人员、机器、环境和管理四个评判指标,构造出风险评估的判断矩阵并建立综合评判指标体系。利用AHP法科学地确定各个指标的权重,结合TOPSIS理论方法计算逼近度并计算风险安全等级。通过应用案例表明,基于AHPTOPSIS的起重设备风险评估的预测结果与实际使用情况相一致。该方法从多种方面考虑了影响风险安全的因素,有效避免了把单因素作为判据的局限性与片面性,且预测结果较科学、准确,能够进一步揭示各因素的影响程度。同时该方法可作为安全风险评估的一种预测方法,也可应用于其他系统工程中。
The risk assessment model of the lifting equipment was established by using AHP and TOPSIS.The risk-safety-related evaluation indexes were selected from four aspects:person,machine,environment and management.Based on the comprehensive evaluation index system,the AHI method is used to determine the weight of each index,and the AOPSIS theory is used to calculate the approximation degree and calculate the risk and safety level.The application results show that the prediction results of FEMA risk assessment based on AHP-TOPSIS are consistent with the actual use.This method considers the factors that affect the risk and safety from various aspects,which effectively avoids the limitation and one-sidedness of the single factor as the criterion,and makes the prediction result more scientific and accurate,and can further reveal the influence degree of each factor.At the same time,this method can be used as a prediction method of safety risk assessment and can be applied to other systems engineering.
