基于BP神经网络的建筑工程造价快速估算方法

A quick cost-estimating method for the civil engineering based on BP neural network

在对建筑工程造价影响因素分析的基础上给出了样本的定性定量描述方法,建立了建筑工程造价资料快速估算的BP神经网络模型,用已建典型工程资料对BP神经网络进行训练,实现了工程造价资料的快速估算,实例证明该方法是可行的,估算结果是可靠的。

On the basis of the analysis on factors affecting the cost estimating of civil engineering, the qualitative descriptive method of is given. The BP neural network model of quick costestimating method of civil engineering is set up. The BP neural network model is trained by a certain samples obtained from some typical engineering built. The quick costestimating method is performed. It is sure that the method is practical and the estimating results are reliable due to having been proved by lots of examples.
