摘要

针对桥式起重机安全评价问题的不确定性,提出了一种基于IAHP和专家群决策的桥式起重机安全综合评价方法。首先建立了桥式起重机安全评价指标体系,提出了起重机安全评价等级和区间数等级,利用区间层次分析法确定了评价指标的区间数权重;然后结合区间数理论与群决策方法构建了基于区间层次分析法和专家群决策的桥式起重机安全评价模型;最后利用实例对某通用桥式起重机的桥架、起升机构、运行机构和人的安全因素4个指标进行安全性评价。结果表明,该起重机桥架的安全性"较好",运行机构和人的安全因素安全性为"中等",起升机构的安全性一般,需要重点关注和改善,结果与同类方法结论相同,但论据更加充分,可信度高,从而验证了该综合评价模型的合理性和有效性。
        Aiming at the uncertainty of the safety evaluation of bridge cranes,a comprehensive safety evaluation method for bridge cranes based on IAHP and expert group decision-making is proposed.Firstly,the safety evaluation index system of bridge crane is established. The safety evaluation grade and interval number of crane are proposed. The interval number weight of the evaluation index is determined by interval analytic hierarchy process. Then,combined with the interval number theory and the group decision method,the bridge crane safety evaluation model based on interval analytic hierarchy process and expert group decision-making is constructed. Finally,the bridge,hoisting mechanism,running mechanism and people of a general bridge crane are used. Safety factors 4 indicators for safety evaluation. The results show that the safety of the crane bridge is "better",and the safety of the safety mechanism of the operating mechanism and people is"medium". The safety of the lifting mechanism is general and needs to be focused and improved. The result is the same as the conclusion of the similar method,but the result is the same. The evidence is more complete and the credibility is high,which verifies the rationality and effectiveness of the comprehensive evaluation model.
