Construction Duration Prediction Model of Power Transmission and Transformation Project Based on BP Neural Network

There are many factors affecting the total construction duration of power transmission and transformation project, resulting in low accuracy of construction duration prediction. And the traditional construction duration prediction method has some limitations to a certain extent. The prediction results mainly rely on historical information materials and expert judgment, so it has always been the difficulty of prediction. Aiming at the existing problems, a total construction duration prediction method of power transmission and transformation project based on BP neural network theory is proposed. The theory has high generalization ability and the ability to solve nonlinear influencing factors, which can greatly improve the accuracy of construction duration prediction.
