基于BP神经网络的市政排水工程造价估算

在综合分析市政排水工程特征的基础上,构建了基于BP神经网络市政排水工程造价估算指标体系和工程造价估算模型,并设计了基于Matlab神经网络工具箱函数的算法程序,用该模型对样本集进行了学习训练和仿真测试,结果表明该网络模型具有较好的泛化能力,能够较准确地估算工程造价.

On the costs estimation of the municipal drainage projects based on the BP neural networks

On the basement of the comprehensive analysis of the features of the municipal drainage projects,the paper establishes the costs estimation index of the municipal drainage projects based on the BP neural networks and the estimation models of the project costs and designs the calculation procedure for the toolbox function,based on Matlab neural networks.It uses the model to undertake the learning training and simulating training for the samples and the result displays the network model has better generalizing capability and is able to estimate the project costs more precisely.
