摘　　要：提高成本预算的效率和准确度是建筑工程管理中的一个重要部分,而现有的成本预算还很大程度上依赖于造价人员的主观判断。通过对成本预算流程的分析,在本体网络方法的基础上,将成本预算流程分解为4个子模块,包括清单项目概念模型、工程量计算规则、施工方案本体和定额项目概念模型,并分别用本体语言进行表达和解释,最终构建了一个成本预算本体网络。借助基于本体网络的成本预算本体知识库,预算人员能够利用BIM设计数据实现成本预算中计量与套价的自动化。Improving the efficiency and accuracy of cost estimation is an important part for construction engineering management. Nowadays, cost estimation still greatly depends on the subjective decision of project cost personnel. By analysis of the process of cost estimation, based on Neon methodology, this paper decomposes the process into four part, including conceptual ontology of bill item, calculation rule of quantities, ontology of construction scheme and conceptual ontology of quota item, and then respectively expresses and explains by the ontology language, ultimately builds an ontology network of cost estimation. With cost estimation ontology knowledge base based on ontology network, cost estimator can utilize the BIM data to achieve automation of quantities and price calculation in the process of cost estimation.
