Optimization of Emergency Epidemic Prevention Material Reserve and Supply System of Shanxi Province in China: Based on Anylogic Simulation

Due to the randomness and uncertainty of epidemic occurrence, there are insufficient emergency supplies and low efficiency of transportation equipment in Shanxi Province. In order to meet the needs of materials in Shanxi Province, it is urgently necessary to establish a reserve and supply system with perfect facilities and equipment. According to the geographical location of 11 prefecture-level cities in Shanxi Province and the actual situation of transportation equipment, this paper simulates the location of warehouse construction in each city. Through simulation modeling, the emergency epidemic prevention materials reserve and supply system of prefecture-level cities in Shanxi Province was simulated under the epidemic situation. The research idea of "simulation-analysis-optimization-summary" was defined, and the AnyLogic software was used to simulate and analyze the emergency epidemic prevention materials reserve and supply system of the whole Shanxi Province. Through the simulation of different scenarios, the optimization direction of transportation equipment is obtained. Based on the optimization effect of each plan of transportation equipment loading on the emergency epidemic prevention materials reserve and supply system in Shanxi Province, the best optimization plan was obtained. The results show that the efficiency of transportation equipment allocation is improved and the loading capacity of transportation equipment is reasonable and effective. After optimization, the order backlog of each prefecture-level city storage warehouse is reduced, and the order processing time is reduced. The optimization ideas proposed in this paper provide the optimization direction for the emergency epidemic prevention materials reserve and supply system in Shanxi Province, and also have certain guiding significance for how to deal with major public health emergencies.
