technical field

The present application relates to the technical field of raw material inventory management, and in particular, to an inventory management method and a related device.

Background technique

Currently, inventory management considers either supply uncertainty alone or demand uncertainty alone. Uncertainty of supply alone or uncertainty of demand alone leads to a safety stock strategy (by holding a certain amount of additional inventory to protect against the risk of short-stocks due to actual demand being greater than forecast demand) versus an exception information strategy (By canceling the purchase orders that have been issued to reduce the risk of redundancy caused by the actual demand being smaller than the forecast demand) Inconsistency and coordination make the matching standards of supply and demand inconsistent, resulting in low efficiency of inventory management.

Detailed ways

The embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application. The terms used in the implementation part of the embodiments of the present application are only used to explain the specific embodiments of the present application, and are not intended to limit the present application.

Please refer to FIG. 1A. FIG. 1A is a schematic diagram of a safety stock formula provided by an embodiment of the present application. The safety stock formula is: safety stock=1.29*standard deviation*delivery period^0.7, the correctness of the safety stock formula is based on several a strong assumption. First, assuming that the random demand satisfies the normal distribution with the mean point forecast, the probability that the demand is less than (mean + 1.29*standard deviation) is 90%. And this assumption often does not hold. Random demand does not show a symmetrical normal distribution, but a long-tailed distribution, with a relatively small probability of a large value. Second, it is assumed that inventory and in-transit inventory are certain, and only the uncertainty of demand is considered. However, there is often uncertainty in the supply, and the supplier may promise to deliver on time and quantity, but actually delay delivery. Therefore, the risk of missing material does not only come from an increase in demand, but also from a decrease in supply. So safety stock needs to consider this part of the risk. Finally, this formula does not take into account the individual characteristics of the materials.

Please refer to FIG. 1B . FIG. 1B is a schematic diagram of a kind of exception information provided by an embodiment of the present application. There is no corresponding research in the academic community for the exception information. In industry applications, when generating exception information, the system compares the total demand forecast during the delivery period with the total supply within the delivery period. As long as the total supply is greater than the total demand forecast, the excess will be canceled. Again, the uncertainty of demand and supply is not taken into account. It does not take into account the fluctuations in demand and the impact of fluctuations in supply, and only relies on point forecasts. When there is a deviation between the actual value and the predicted value, the supply and demand will be unbalanced again, so the decision-making will be overly sensitive, and the purchase order and the cancellation order will be repeatedly issued alternately. Just cancelled this week, new order next week. Or just cancel a new order.
