摘要
根据神经网络原理和工程造价估算的特点,通过研究工程造价的构成,建立了工程造价估算模型.从模型调试和测试结果来看,经测算其精度基本可以满足实际工程投资估算的需要,模型具有较好的应用价值.
According to the basic principles of the neural network and the characteristics of project cost estimation,the functions of structures and their characteristics was reviewed in detail,the model of cost estimation for const ruction engineering based on BP Neural Network is presented.The results show that the precision meets the estimation requirement well.Therefore,it shows that the neural network using in cost estimation of construction project have better value.
