基于神经网络的公路工程承发包价格发展预测

The Prediction of Contract - issuing Price of Highway Engineering Based on Neural Network

公路工程承发包价格是公路工程造价研究的重要内容。合理确定影响公路工程承发包价格的多种因素，采用基于BP神经网络的公路工程价格预测方法，建立模拟承发包价格与其影响因素间的非线性关系预测模型，经过训练与检验、数据预测，结果表明，该方法实用性强，具有一定的理论与实际应用价值。

The research on contract - issuing price of highway engineering is an important part of highway engineering costs. Many factors which influences the contract - issuing price are reasonably determined, and the price is forecasted based on BP neural network, the prediction model of nonlinear relationship between contract - issuing price and influence factors is established. After testing and data forecasting, the result turns out that this method is practical with certain theory and actual application value as well.
