Analysis and forecast of cold chain logistics demand for aquatic pre-made dishes in Guangdong Province
In order to predict the market demand for aquatic pre-made dishes in Guangdong Province,an evaluation index of cold chain logistics demand for aquatic pre-made dishes is constructed from four aspects:regional economic development level,market supply and demand level,transportation level,and cold chain technology level.The main factors affecting the change of cold chain logistics demand for aquatic pre-made dishes are studied by gray correlation analysis method.The first-order unitary differential equation GM(1,1)in the gray model(GM)and long short-term memory(LSTM)neural network are used to compare and analyze the cold chain logistics demand for aquatic pre-made dishes in Guangdong Province from 2015 to 2021.The results showed that the main influencing factors affecting the development of cold chain logistics demand for aquatic pre-made dishes in Guangdong Province are cargo turnover and cold chain refrigeration level.The average relative errors of GM(1,1)and LSTM neural network are 2.68％and 0.22％,respectively,and the prediction accuracy of the latter is significantly better than that of the former.Using LSTM neural network to predict the cold chain logistics demand forcargo in Guangdong Province from 2022 to 2024,the demand for cargo in Guangdong Province is on the rise,and it is expected to reach 509.09 million tons in 2024.Guangdong Province should focus on cold chain infrastructure building,ensure stable temperature of aquatic pre-made dishes during storage and transportation,strengthen food supervision of aquatic pre-made dishes,ensure food quality and safety,and continuously promote the development of the aquatic pre-made dishes cold chain industry.
