摘　　要：通过n维欧几里得距离来度量任意可行方案与理想解和负理想解之间的差异,运用信息熵理论反映指标本身的效用值并表达权重。在构建包括费用、风险、总工期及施工技术条件等评价指标体系的基础上,将熵理论与TOPSIS有机结合,建立了TOPSIS评价模型,对施工导流方案进行评价。通过实例分析,验证了TOPSIS评价模型的合理性和可靠性,为施工导流方案的综合优化决策,提供了一条新的途径。The n-dimensional Euclid distance is used to measure the difference between any feasible solution and the ideal solution and negative ideal solution.The information entropy theory is used to reflect the utility value of the indicator itself and express the weight.On the basis of constructing an evaluation index system including cost,risk,total construction period,and construction technical conditions,the entropy theory is organically combined with TOPSIS to establish a TOPSIS evaluation model for evaluating the construction diversion scheme.Through case analysis,the rationality and reliability of the TOPSIS evaluation model have been verified,providing a new approach for the comprehensive optimization decision-making of construction diversion schemes.
