Rolling Prediction of Emergency Supplies Based on Postdisaster Multisource Time‐Varying Information
Complexity, Volume 2022, Issue 1, 2022., 2022 Accurate prediction of material demands is key to ensuring the overall efficiency of emergency rescue operations. From the perspective of the prediction method, the single‐material static prediction method based on the overall data has limitations. This method cannot flexibly adjust multiperiod material demands. Considering data sources, acquiring data
