Combination Prediction Model of Mooring Load Based on Wavelet Analysis Method and Neutral Network
Hao Zhang · 2013
To achieve high-precision prediction for mooring load data,based on wavelet analysis method and BP neutral network method,a forecast combination algorithm was proposed.Wavelet analysis method was used to make multi-scale decomposition and reconstruction calculations for original no-stationary mooring load series,and multi-layer steadier mooring load series was obtained.Then BP neutral network method was used to build no-stationary prediction models for each layer,and realize forecast calculation.Simulation results show that the combination algorithm attains high-precision forecast results.The combination algorithm has respectively excellent subdivision and self-learning ability.The combination algorithm can meet requirements of short-term early-warning of mooring load.
