Machine Learning for Ship Energy Consumption Predicting Based on Noon Report Data
摘要
Accurate fuel consumption predicting can assist ship managers in making more informed decisions regarding route selection and speed adjustments, thereby enhancing shipping efficiency. Due to the characteristics of data features and the attributes of data-driven methods, it is challenging to find a single energy consumption prediction method suitable for all data samples. Therefore, it is necessary to analyze the performance of different forecasting methods based on the specific characteristics of energy efficiency data and research objectives, selecting the optimal method for fuel consumption prediction. This study utilizes shipboard noon report data and employs Least Absolute Shrinkage and Selection Operator(LASSO), Back Propagation Neural Network (BPNN), Decision Tree Regression (DTR), and Support Vector Regression (SVR) for fuel consumption predicting. Experimental results indicate that LASSO achieves the highest prediction accuracy, with a root mean square error of 1.512 Metric Ton(MT)/day, an average absolute percentage error of 2.801%, and a prediction accuracy of 97.199%. The proposed ship energy consumption prediction method provides valuable references for fuel anomaly detection, energy efficiency assessment, and energy efficiency optimization.
