摘要
建立了建筑工程成本的神经网络预测模型 ,并在微软Excel电子表格上模拟运行 ,对权值的优化 ,运用Ex cel“加载宏”程序 ,可以直接在电子表格上进行 ,实践结果表明预测结果满意 ,预测误差达到 0 .4 %。为了更好地预测新的工程项目 ,模型中还包含了敏感性分析模块 。
A model based on NN about project cost estimation is established and simulated on Microsoft Excel .To optimize the NN weights , we use Solver , an Excel add-in program which can be conducted directedly on NN spreedsheet ,to experiment it .The illustration shows the results is satisfied and the errors are 0.4%. For practicality ,sensitivity analysis has also been incorporated.
