摘要: 目前中国与外国先进造价的管理模式有较大差距,尤其在以造价估算系统为代表的信息系统方面。基于广义径向基函数神经网络的聚类算法,选取了2003—2007年间北京市普通商用土建工程数据为样本,提取了商用建筑的主要工程成本指标,对单方成本价格估算进行了检验。结果证明,该方法在精度方面符合要求,与其他方法比较,还具有速度和泛化能力的优势,为造价快速计算智能化提供了方法依据,也为工程管理者们提供了更好的决策依据。

Abstract: At present, China-s cost management lags far behind foreign countries, especially in the cost estimation information system. Based on Radial basis function neural network nonlinear model, the paper selected ordinary commercial civil engineering data in the 2003-2007 years as samples; chose project cost indicators of the main commercial buildings, and examined the cost prices. The results show that the method meets the requirements in the precision. Compared with other methods, it has the advantage of speed and generalization ability。The method provides project managers a better basis for decision making.
