Supermarket Replenishment and Pricing Decisions Based on a Single-Objective Planning Model

Vegetables contain rich nutritional value and are an indispensable part of people's daily lives, but their freshness period is relatively short and susceptible to the influence of season, temperature, time and other factors, so the development of reasonable pricing decisions is of great significance to the revenue. In this paper, firstly, we use Spearman's correlation coefficient to study the intrinsic relationship between the commodities for sale in order to explore the correlation between the sales volume of commodities. Second, we develop a single-objective planning model to optimize the replenishment and pricing strategy decisions. Finally, in order to consider the impact of inventory on the replenishment strategy, we introduce inventory constraints on top of the original constraints and build a 0–1 dynamic planning model to further optimize the replenishment decision. With this model, we can develop an optimal replenishment strategy with constrained inventory levels to achieve better business results.
