【摘要】：对差异化较大的混合建筑进行造价估计一直是建筑学中的难点。主要是因为,在混合建筑中,建筑之间存在着差异化不同的内在联系,这种联系之间随着建筑的不同,相互的约束性也不同。传统的造价估计建模,对差异化较小的建筑造价采用叠加的方法完成。对大差异的建筑估计往往存在高维约束,很容易造成模型不收敛,评估模型不准确。提出了一种多造价信息合理限制的混合建筑造价优化模型,选择建筑造价估计限制属性变量,构建特征因素模糊限制集,采用隶属函数描述混合建筑特征的相似度,获取混合建筑特征因素的量化值,得到模糊限制因子集的隶属度,将模糊数学同限制模型的最佳解进行有效融合,塑造了模拟混合建筑造价信息估算模型,实验结果说明,所提模型可对不同类型的混合建筑造价进行准确估计,具有较高的估算效率和精度。
[Abstract]:It has been a difficult point in architecture to estimate the cost of a mixed building with great difference, mainly because in the mixed building, there are different internal relations between the buildings, which are different with each other. The traditional cost estimation modeling is accomplished by superposition method for the construction cost with small difference. The large difference of the building estimate often has high dimensional constraints, which is easy to cause the model not to converge. The evaluation model is not accurate. This paper presents a mixed building cost optimization model with reasonable limit of multi-cost information, selects the attribute variable of construction cost estimation, and constructs the fuzzy restriction set of characteristic factors. The membership function is used to describe the similarity of the features of the hybrid architecture, and the quantization value of the feature factors of the hybrid architecture is obtained. The membership degree of the fuzzy limiting factor set is obtained, and the fuzzy mathematics is effectively fused with the optimal solution of the restricted model. A model for estimating the cost information of a hybrid building is built. The experimental results show that the proposed model can accurately estimate the cost of different types of hybrid buildings, and has a high efficiency and accuracy.
