Multiparameter Sensitivity Analysis of Operational Energy Efficiency for Inland River Ships Based on Backpropagation Neural Network Method

With the introduction of,energy effiCiency operational indicator (g01):to inland river ships, a Oultipararrieter sensitivity analysis rilethod: was proposed tO3analyZe the parameters affecting the operational energy efficiency of inland river Ships On the Oasis of experimental data, a,mod0 based on a,paCkpropagation 417t if ielat neural fletwbrki(BP-ANN) 1,10- predicting the EEGI,wat set Ca.
