摘要
为解决装配式建筑施工安全评价指标赋权的主观性以及评价的复杂性,提出基于离差最大化及五元联系数的装配式建筑施工安全评价方法。该方法利用专家评价各个指标对应五个安全等级的隶属度,运用离差最大化法确定评价指标的权重,并利用五元联系数的运算法则计算综合五元联系数,根据综合五元联系数的系数分量大小关系判断态势排序,最后根据态势排序确定安全评价的结果。实证分析表明,该方法在装配式建筑施工安全评价上是有效的和可操作的,能够为装配式建筑施工安全管理提供决策依据。
In order to solve the subjectivity in determining index weights and the complexity of evaluation of prefabricated building construction safety evaluation,a method is proposed for evaluating the construction safety of prefabricated buildings based on the maximization of deviation and the five-element correlation.The membership of the five security levels corresponding to each evaluation index was evaluated by invited experts.The weight of each evaluation index was determined with the deviation maximization method;the comprehensive five-element connection number was calculated by using its own algorithm.The state sequence was determined by the size of the contact component of comprehensive five-element connection number.The results of safety evaluation were determined according to the state sequence.Empirical analysis shows that the method is effective and operable in the construction safety evaluation of prefabricated buildings.Therefore,it can provide decision-making basis for the construction safety management of the prefabricated buildings.
