Research on Energy Consumption Prediction of Combined Models in Discrete Manufacturing Enterprises

[摘要] In discrete manufacturing enterprises, accurate prediction of energy consumption provides an important data basis for the strategic development and strategy formulation of enterprise managers. This paper uses the GM(1, 1) model and System Dynamics model to predict and analyze the energy consumption of a shipbuilding enterprise respectively. Secondly, the Shapley value method is used to determine the weight of each prediction model in the combined model, and to construct the energy consumption combination prediction model of a shipbuilding enterprise. The prediction results show that the prediction accuracy of the combined model is higher than that of the single prediction model, which provides a new prediciton method for a shipbuilding enterprise and has reference value for other discrete manufacturing enterprises.
