First, based on the properties of this integral method, a new time-response equation is derived, and the GHM-GM(1,1) is constructed. To further optimize the model\u2019s performance, a new parameter, \u201c\u03b4\u201d is introduced. This parameter adjusts the amount of data supplementation and deletion each time. Additionally, a selector is equipped to determine the optimal window size, ensuring that the result with the minimum prediction error is selected and output during each data prediction process. Subsequently, to verify the model\u2019s validity, we compare it with other GM(1,1) models through a simulation experiment and two practical cases. We objectively evaluate the characteristics and advantages of GHM-GM(1,1) through specific performance indicators and evaluation criteria. Finally, using the new model, the population affected by natural disasters in China was predicted to complete the emergency material demand prediction.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Findings<\/jats:title>\n                  <jats:p>The new prediction model has demonstrated higher prediction accuracy in three comparative experiments, verifying the validity and practical application potential of the model. Results show that the model more accurately predicts emergency material demand by capturing data trends and fluctuations, outperforming other models in accuracy.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Originality\/value<\/jats:title>\n                  <jats:p>In this study, a new GM(1,1) is proposed, which integrates the Gauss\u2013Hermite integral and metabolism GM(1,1), which significantly improves the accuracy and reliability of gray prediction. The introduction of the optimal window \u201c\u03b4\u201d not only further enhances the prediction accuracy of the metabolism GM(1,1) but also increases the adaptability of the model.<\/jats:p>\n
