Traditional retail has experience of supply, which seriously affects the development of the retail industry. According to different application scenarios and needs, different replenishment strategies are proposed. In the intelligent vending machine use scenario, an optimized replenishment strategy of a dynamic matrix model is proposed, which realizes intelligent replenishment on demand. This strategy calculates the replenishment value at different times of the day based on the relationship between sales statistics, predicted sales value, zero inventory, the number of merchandise lanes of the vending machine, and time series. The table dynamically adjusts the replenishment cycle. According to the output results, compared with other replenishment methods such as supply based on sales experience in the past, this replenishment strategy can improve the turnover rate of goods, increase the sales of goods, and also save the replenishment operating costs.

Key words: replenishment strategy, time series, vending machine, matrix model, replenishment cycle
