Risk Assessment Model of Aquatic Product Cold Chain Logistics Based on PSO-BP Neural Network

The risk assessment model of cold chain logistics of aquatic products was established by PSO-BP neural network, and the risk index of cold chain logistics of aquatic products was determined. The model training results show that the risk of refrigerated truck transport is the highest and the risk of public event is the lowest in the cold chain logistics of aquatic products. Strengthen the updating of refrigerated truck equipment technology, do a good job in the maintenance and maintenance of vehicles and chillers, avoid damage caused by improper operation, and promote the stable development of cold chain logistics.
