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 present invention provides an inventory management method and device, including: performing prediction model training according to the prediction data of the target product; predicting the daily product demand prediction value and the corresponding normal quantile in the future target time period according to the prediction model; Determine the daily average value of product demand forecast and the average value of total demand based on the daily product demand forecast value; determine the standard deviation of adjusted demand; determine the target inventory in the future target time period based on the average value of total demand, the service level coefficient and the standard deviation of adjusted demand; The target inventory and the daily average value of product demand forecast determine the minimum inventory turnover storage days; in this way, use the forecast model to predict the daily product demand forecast value in the future period, and predict the change of demand fluctuation in units of days to ensure the forecast accuracy; The daily forecast value of product demand is converted into the average value of total demand in the future time period, and the standard deviation of demand is adjusted to overcome the forecast anomalies of high volatility products and improve the forecast accuracy 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...
