摘要
针对超高层装配式建筑施工特点,通过调查研究,运用4M1E理论,依据相关标准规范,建立超高层装配式建筑施工风险评价指标体系。结合三元区间数理论,运用专家赋值法确定指标三元隶属度,并计算指标的序列熵,得到客观权重。按指标层级分级计算评判矩阵及评判向量,获得三元评语区间数,参照评语集确定安全等级。最后通过实例验证这种评价方法的实用性。
This paper researches the construction characteristics of super-high prefabricated buildings,establishes the index system of construction risk evaluation of super-high prefabricated buildings on the basis of the theory of 4M1E and relevant standards by investigating and researching.Combining the theory of Ternary Interval Number,uses the expert assignment method to determine the ternary membership degree of the index and calculates the sequence entropy of the index to obtain the objective weight,calculates the evaluation matrix and evaluation vector according to the index hierarchy,and obtains the number of three-part evaluation intervals,determines the safety level by referring to the evaluation set.Finally,gives an example to verify the practicability of the method.
