基于信息熵的大跨钢结构施工方案多指标决策管理方法

ENTROPY-BASED MULTI-SPAN STEEL STRUCTURE CONSTRUCTION DECISION MAKING MANAGEMENT METHOD

根据大跨钢结构施工的特点,采用定性与定量相结合的方法建立施工方案的综合评价指标体系,引入集值统计方法、信息熵的多指标决策管理方法,建立方案的综合评价模型。并结合工程实例给出了计算方法和步骤,对各个方案评价结果进行排序,从而确定最佳方案。

According to the characteristics of large span steel structure construction, the combination of qualitative and quanti- tative methods to establish the construction program of comprehensive evaluation index system, the presentation of set-valued statistics, information entropy of the multi-attribute decision management, the establishment of the pro- gram evaluation model. An engineering example is given of the calculation methods and procedures, evaluation of various options to sort the results to determine the best option.
