[摘 要] 针对建筑工程项目投资大、周期长、施工不安全因素多等特点,对工期隐性成本进行三级科目设置,以深化对建筑工程项目工期隐性成本的认识。通过分析神经网络与工程网络图的相似点,构建工期隐性成本神经网络控制模型,同时针对传统神经网络的缺陷,引入基于自适应学习速率的算法,提升了神经网络技术对于工期隐性成本控制的准确度。

Abstract: According to the characteristics of construction project, such as large investment, long period, numerous unsafe factors in construction, it sets the third level of duration implicit cost, deepening the understanding of the duration implicit cost in construction project. Through analyzing the similar characteristics of the technique of project network diagram and neural network, it builds the duration implicit cost control model of neural network. Aiming at the defects of the traditional neural network, the algorithm based on self-adaptive learning-rate is introduced, improving the accuracy of the control for the neural network technique.

Key words: construction project; duration implicit cost; neural network; cost control model
