基于熵权的施工机械选型研究

将熵理论应用于产品型号选择,为工程项目选择合适的施工机械.利用熵理论过滤各型号中数值很接近的指标,减轻评价工作量;对定量和定性指标采用不同的无量纲化方法,得出标准评价矩阵;利用熵权修正主观指标权重,得到综合权重;根据各产品与理想产品的相对接近度来选择产品.并通过实例验证了该方法的可行性与实用性.

Study of Selecting Construction Machinery Based on Entropy Weight

In order to select appropriate construction machinery,we can put across choosing manufactured product model number under the entropy theory.Entropy not only can help to filter the adjacent data,which can alleviate amount of work,but also can standardize qualitative and quantitative numerical data through different dimensionless ways and ultimately get the standardization of the evaluation matrix.Also entropy-weight is used to modify subjective weight,through which we can have compositive weight.Then according to the relative approach degree,appropriate product can be chosen.Finally,the case study proved that the method is reasonable and practical.
