“…Stackelberg game was used to solve the optimal solution of SC inventory model (Choudhury et al, 2022), and it was concluded that retailers preferred O2O model in the fresh supply chain sales mode with fresh-keeping strength. Considering freshness and consumer preference, a fresh dynamic game model on temperature control and demand function of fresh agricultural products is established, which shows that the input level of temperature control, profit and overall profit of supply chain in the three-level supply chain composed of fresh agricultural Fresh products' cold chain products suppliers, retailers and third-party logistics are positively correlated with consumer preference (Luo et al, 2022;Sun et al, 2022). In terms of the algorithm models for freshness prediction, such algorithm models as the blueberry freshness prediction model based on machine learning (Huang et al, 2023), the real-time cold chain egg freshness prediction method based on transfer learning (Kim et al, 2022), and the strawberry cold chain transportation quality perception method based on BP neural network (Qiao et al, 2022) are proposed.…”
