施工导流方案优选的熵TOPSIS决策模型

针对现阶段施工导流方案优选存在的问题,选择工程的导流投资、经济损失和施工强度等3种因素作为决策指标,引入信息熵来计算各评价指标的权重,构建基于信息熵多目标导流标准的TOPSIS决策模型,通过求解评价方案的欧氏贴近度确定施工导流的优选方案,并通过工程实例加以验证.研究表明,该方法避免了由于主观原因造成的误差,评价结果客观...

TOPSIS Decision Model Based on Entropy of Optimization of Construction Diversion Schemes

Aiming at the problems existed in optimization of construction diversion schemes,three factors such as the diversion investment,economic losses and the construction intensity were choosen as decision indexes,and the information entropy was introduced to calculate the weight of every evaluation,then TOPSIS decision model with the multipurpose diversion standard was established on the basis of information entropy.Euclid approaching degree of the evaluation scheme was solved for determining the optimal scheme of construction diversion,and the model was verified by the engineering example.The result showed that this model could avoid errors caused by subjective factors and the evaluating results were objective and fair,as well as the method was simple.It provided a new way for the optimization of construction diversion schemes.
