摘要
以构建合理、科学的施工方案评价方法为目标,将灰色聚类理论和信息公理集成应用于建设工程施工方案评价中,构建了基于灰色信息公理的施工方案评价模型.基于层次分析法构建施工方案评价指标体系,针对评价体系中的模糊性指标,利用灰色三角白化权函数进行白化处理;通过对施工方案各评价指标设计范围和系统范围的扩展改进了信息量计算公式,使计算结果更符合实际.以建设工程施工方案的优选为例,对所提方法进行验证,结果表明是科学的,为建立科学合理的评价提供了方法.
Aiming at building a rational and scientific evaluation method for construction schemes,the grey clustering theory and information axiom of integration are applied in the evaluation of construction schemes to construct an evaluation model for construction schemes.The evaluation index system of construction system is built using analytic hierarchy process,and qualities indicators of an evaluation system are whitened using a grey triangular whitened weighting function.Through improving the information calculating formulas,the design range and system wide of a construction schema are expanded to make the results more realistic.A case study of a construction-schemes optimization project is proposed to demonstrate and analyze the proposed method,providing a theoretical basis for establishing a scientific and reasonable evaluation method.
