Abstract

Addressing the issue of insufficient accuracy in procurement demand forecasting under market volatility, this study investigates the Prophet model with exogenous variables. It outlines the comprehensive workflow encompassing data preprocessing, feature reconstruction, and model training, while introducing trend decomposition and forecasting implementation methods constrained by multi-source features. Comparative experimental results demonstrate that the improved model reduces RMSE by 21.5% and MAPE by 34.2% in high-volatility intervals, significantly enhancing prediction stability. This validates the effective corrective role of exogenous variables in addressing complex market disturbances.
