摘要:

针对传统碳排放预测方法中制造信息多源异构、参数不确定性强等突出问题,整合加工、能源、资源、排放多维影响因素,识别并定义制造场景,实现了碳排放影响因素的统一表征与描述;融合随机森林的决策树集成机制与贝叶斯算法的自适应超参数优化,形成了“特征筛选-模型训练-参数调优”的三阶预测体系,支持碳排放的高精度预测;构建了蒙特卡罗-贝叶斯优化随机森林不确定性分析方法,甄别碳排放敏感参数并量化其影响,通过参数优化改进来提高可靠性。以风机叶片加工为例验证预测方法的有效性,结果表明,该方法的碳排放预测结果拟合度良好,经不确定性分析后变异系数降低0.0347,显著提高了预测结果可靠性与决策支撑能力。

Abstract:

Conventional prediction methods faced challenges such as multi-source heterogeneity and strong parameter uncertainty, so equipment, process, and resource-related factors were integrated to identify and define manufacturing scenarios, enabling the unified representation and description of carbon emission influences. The ensemble mechanism of random forest decision trees was combined with Bayesian adaptive hyperparameter optimization to establish a three-stage prediction framework “feature selection, model training, parameter tuning” for the high-efficiency prediction of carbon emissions. A Monte Carlo-Bayesian optimized random forest approach for uncertainty analysis was developed, where sensitive carbon emission parameters were identified and their impacts were quantified to enhance reliability through targeted parameter optimization. A case study on wind turbine blade machining demonstrated the effectiveness of the proposed method. The results show excellent agreement between predicted and actual carbon emissions. After uncertainty analysis, the coefficient of variation is reduced by 0.0347, significantly improving the reliability of the prediction results and supporting more robust decision-making.

Key words: manufacturing scenario, carbon emission prediction, Bayesian-optimized random forest, uncertainty analysis
