With the intensification of retail competition and the diversification of consumer demand, the pricing and replenishment decisions of vegetable products have become an important challenge for supermarket operators. This paper analyzes the operating characteristics of vegetable commodities and combs the existing pricing strategy and replenishment decision theory. On this basis, using Matlab software, combined with vegetable sales data, considering the average loss rate of vegetables, expected sales and other factors, an automatic pricing model was constructed to achieve pricing optimization based on cost-plus strategy. In the course of the study, SPSSPRO frequency analysis, Pearson correlation coefficient analysis and other methods were used to reveal the distribution characteristics of vegetable sales and the correlation between categories. In addition, the replenishment decision-making optimization model is designed, and the optimal automatic pricing strategy and replenishment quantity are obtained by intelligent optimization methods such as simulated annealing algorithm and particle swarm optimization algorithm. The empirical results show that the model proposed in this paper can significantly improve the sales efficiency and profit level of vegetable products.展开更多
