[摘　要]　針對建筑工程項目投資大、周期長、施工不安全因素多等特點，對工期隱性成本進行三級科目設(shè)置，以深化對建筑工程項目工期隱性成本的認識。通過分析神經(jīng)網(wǎng)絡(luò)與工程網(wǎng)絡(luò)圖的相似點，構(gòu)建工期隱性成本神經(jīng)網(wǎng)絡(luò)控制模型，同時針對傳統(tǒng)神經(jīng)網(wǎng)絡(luò)的缺陷，引入基于自適應(yīng)學習速率的算法，提升了神經(jīng)網(wǎng)絡(luò)技術(shù)對于工期隱性成本控制的準確度。

[關(guān)鍵詞]　工程項目；工期隱性成本；神經(jīng)網(wǎng)絡(luò)；成本控制模型

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
