Embodiment 1
[0044] This embodiment provides an inventory management method, such as figure 1 As shown, the methods include:
[0045] S110, for the target product, acquire data corresponding to the demand forecast of the target product, the data including: historical sales data, product information, promotion data and holiday data;
[0046] Here, the target product is generally fast-moving consumer goods, such as food, beverage, etc., and the target product in this embodiment is beer. Generally speaking, the target inventory decision of the target product mainly includes two factors, the first is the demand forecast of the target product in the future time period, and the second is the forecast of the minimum inventory turnover days.
[0047] Therefore, for the target product, the data corresponding to the demand forecast of the target product is obtained. The data includes: historical sales data, product information, promotion data and holiday data. Wherein, the product information may ...
Embodiment 2
[0075] This embodiment improves an inventory management device, such as figure 2 As shown, the device includes: an acquisition unit 21, a training unit 22, a prediction unit 23, and a determination unit 24; wherein,
[0076] The acquisition unit 21 is configured to acquire forecast data corresponding to the demand forecast of the target product for the target product, the forecast data including: historical sales data, product information, promotion data and holiday data;
[0077] A training unit 22, configured to perform prediction model training according to the prediction data to obtain a trained prediction model;
[0078] The prediction unit 23 is used to predict the daily product demand forecast value and the corresponding normal quantile in the future target time period according to the forecast model; the future target time period is the replenishment lead time and the replenishment interval in days Sum;
[0079] Determining unit 24, configured to determine the daily...

Abstract
The invention provides an inventory management method and device. The method comprises the steps of performing prediction model training according to prediction data of a target product; predicting adaily product demand prediction value and a corresponding normal quantile in a future target time period according to the prediction model; determining a product demand prediction daily mean value anda total demand mean value based on the daily product demand prediction value; determining an adjustment demand standard deviation; determining a target inventory in a future target time period basedon the total demand mean value, the service level coefficient and the adjustment demand standard deviation; determining a minimum inventory turnover storage day number based on the target inventory amount and the product demand prediction day mean value; thus, utilizing the prediction model to predict the daily product demand prediction value in the future time period, predicting the change of demand fluctuation by taking days as units, and ensuring the prediction precision; converting the daily product demand prediction value into the total demand mean value in the future time period, overcoming the defect of prediction abnormity of high-volatility products by adjusting the demand standard deviation, and improving the prediction precision and stability.
Description
technical field [0001] The invention belongs to the technical field of FMCG inventory forecasting, and in particular relates to an inventory management method and device. Background technique [0002] Compared with other industries, the supply chain of the FMCG industry has the characteristics of demand pull, long supply chain, short product shelf life, and fast operation rhythm. How to better carry out inventory management, store reasonable inventory at the right time, and minimize inventory levels while ensuring order fulfillment rates are key issues for reducing costs, increasing profits, and improving the competitiveness of enterprises and the entire industry. [0003] At present, the commonly used replenishment strategy in the industry is the target inventory method. The specific operation is to regularly check the inventory level. If the current inventory level is lower than the target inventory, the replenishment will reach the target inventory, otherwise no replenish...
