Figure 12
A diagram of a multi-objective optimization model for emergency materials distribution. The diagram features a central distribution center depicted as a warehouse with a truck, surrounded by four requirement points represented by clusters of buildings with red virus icons. Arrows indicate the flow of materials from the distribution center to the requirement points. The top section of the diagram includes text boxes describing different algorithms and their applications. The left text box mentions LSTM and SEIRS, highlighting the reduction in prediction errors. The middle text box introduces a hybrid PSO-GSA algorithm combined with LSTM for forecasting demand during public health emergencies. The right text box compares the hybrid PSO-GSA algorithm with traditional PSO algorithm and GA. The overall structure emphasizes the dynamic extraction of real-time epidemic information to optimize the distribution of emergency materials.
