对输变电工程静态投资进行准确预测,有助于正确决策工程投资和有效控制工程造价。根据输变电工程建设各分项费用与静态投资之间的逻辑关系和费用构成原理固有的网络拓扑结构,建立了基于贝叶斯网络的输变电工程造价预测模型。通过实证研究,该预测方法有效揭示了输变电工程造价变化的内在规律,为进一步加强输变电工程造价全过程管理,健全输变电工程设计和造价管理体系提供了决策参考。 Accurately forecasting the static investment of power transmission and transformation project can help to make the correct decision on project investment and effectively control the project cost. According to the inherent network topology of the logical relationship between cost and static investment and the cost structure of transmission and distribution project, a forecasting model of transmission and distribution project cost based on Bayesian network is established. Through empirical research, the forecasting method effectively reveals the inherent rules of the cost change of transmission and distribution project, which provides a reference for further strengthening the whole process management of transmission and distribution project cost and improving the design of transmission and distribution engineering and cost management system.
