- Inventory management method Inventory management system and inventory management program
- the present invention relates to an inventory management method for managing inventory quantity, an inventory management system, and an inventory management program.
- the fixed-quantity ordering method is a method of ordering a fixed amount when a certain standard stock is broken.
- the periodic ordering method is a method of ordering at a fixed period (month end, weekend, etc.) only for the shortage of the standard inventory.
- the standard stock which is the basis of inventory management, is the time required for the ordered product to be replenished, that is, the expected shipment volume that is expected to be shipped within the replenishment lead time, and when the shipment exceeds this estimated shipment volume It is calculated based on the safety stock that absorbs the difference.
- Factories and logistics departments adjust order quantities and production quantities so that inventory approaches this standard inventory. The more inventory, the more flexible the order can be, and the higher the on-time delivery rate. However, if the inventory is too large, the inventory turnover will decrease and inventory costs will increase. Therefore, the base inventory needs to be reduced to such an extent that the turnaround rate does not deteriorate so much that the inventory turnover rate is high.
- an inventory management system has been developed that performs a simulation calculation of the base stock in the past based on the past requirements, the actual payout results, and the future required plan, and determines the ordering method based on this (see “Japanese Patent Laid-Open No. 7-192”). 0 6 8 Gazette (Paragraphs 0009-0015, Figures 1-2)). ).
- the standard stock when setting the standard stock, the standard stock is determined based on the order information. For example, in the conventional inventory management system described above, even when a large number of orders with a long delivery date set in advance, so-called “spike orders,” are taken in as a population for simulation of inventory calculation and reflected in the base inventory. I will. However, large orders that are significantly higher than the average order volume are rare. Determining the standard inventory by incorporating temporary data such as spike orders will result in holding more than necessary revolving inventory, increasing inventory costs and preventing efficient inventory management.
- an object of the present invention is to provide an efficient inventory management method using a statistical method, an inventory management system, an inventory management program, and a program.
- An inventory management method for solving the above-mentioned problems manages the amount of inventory.
- ⁇ be the quantity of each of the selected order-receiving units. If the number is less than the threshold, classify the order-receiving unit as a normal order-receiving unit.If a exceeds the threshold, the order-receiving unit receives the order.
- an inventory management method for solving the above-mentioned problem is to manage inventory amount

- the quantity currently on order is e
- the threshold value of the order entry lot is set based on the statistics of the quantity of each order entry lot using an appropriate calculation means, and the quantity of the order entry lot is set to be smaller than this threshold value.
- the special order receiving unit is excluded from the population for inventory calculation as in the present invention, there is substantially no possibility of affecting the delivery date compliance rate.
- the predetermined calculation formula various known calculation formulas for inventory management can be used, but it is preferable to use the formula of the above-mentioned order point / standard stock setting step.
- the ordering point r and the base stock are selected from the order base lots whose delivery date is set from b days before the base date to a day after in the future, and the selected order lots are further selected.
- those whose quantity is less than or equal to a predetermined threshold are classified as “normal order lots” Only ”as the population.
- thresholds are separately set for the order entry lot whose delivery date is set b days before the base date and the order lot whose delivery date is set for a day after the reference S. It is also possible to set “ordinary order intake lot” if the quantity of each selected order lot is below the respective threshold. Providing the respective thresholds in this manner makes it possible to more accurately classify the normal order intake units.
- the reference time refers to a time point used as a reference for determining the reference stock i3, usually the current date.
- the base stock is determined mainly based on the ordering point r, and the ordering point r is determined by the sum of the safety stock and the estimated shipment amount within the replenishment lead time.
- the expected shipment volume within the replenishment lead time is the expected shipment volume within the replenishment lead time (the period from the ordering of the product to the production department to the arrival at the logistics department). It is calculated based on the lot whose delivery date is set between the base time (current time) and a day after the future.
- Safety stock is provided to absorb the difference when the actual order quantity exceeds the estimated shipment quantity within the replenishment lead time. It is calculated based on the delivery date set between b days before and the base time. If the number of days in the future a is set shorter than the number of days in the past b, the safety stock with a certain width will be determined while determining the revolving stock based on the recent future orders. be able to.
- the safety stock is calculated based on the order data of the past b days, that is, the shipment result, and the estimated number of shipments that can be turned inventory is calculated based on the order data of the future a day.
- the optimal reference stock that responds to uptrends based on past performance.
- a warning reference range is set based on the reference stock, and a total of shipment quantities in the future c days from the warning reference time is monitored.
- a warning step may be provided to warn when the standard is exceeded.
- a warning is issued when the reference stock once set does not match the actual shipment amount, so that the person in charge can take the order based on the actual order quantity without missing the machine.
- the standard stock can be reset manually.
- warning reference time may be set when the range of the warning reference or the reference stock is set, or may be set several days before the present time.
- the range of a warning standard can be defined as ⁇ 20% of the standard inventory.
- the means for issuing the warning is not particularly limited.

- a standard inventory adjustment (re-setting) method the following steps must be taken to adjust the standard inventory.
- this warning is used as a trigger to calculate the base stock when the base time of the warning is set as the base time of the base stock, and the result is reset as the base stock. Therefore, if a warning is issued, the reference The population is ordered lots with delivery dates set in the future a days and past b days from the warning reference time.
- Resetting of the reorder point can be performed basically in the same manner as the above procedure. Resetting the base stock and reorder point can also be determined by the number of times the warning has been issued. For example, it is possible to perform resetting only when three consecutive warnings occur.
- FIG. 3 shows the above-described processing of the inventory management system according to the present invention as a flowchart.
- the processing boxes shown in the figure can be rearranged if they are not logically inconsistent.
- the warning judgment box may be placed anywhere after the reference stock is determined.
- the processing is returned to the processing box for threshold determination, but the processing may be returned to another processing box.
- Input of various data ⁇ Reception and storage are actually repeated each time or periodically. Based on the update of these data, the standard stock and order point are recalculated each time the update is performed or at a predetermined cycle. It will be.
- the base stock can be reduced to an appropriate value without lowering the on-time delivery rate. Can be.
- inventory costs can be reduced efficiently without compromising customer satisfaction.
- inventory turnover can be improved by reducing the standard inventory.
- the warning means prompts the person in charge of inventory adjustments in a timely manner, which enables more appropriate inventory management.
- the reference inventory is reduced, and the inventory rotation rate of the conventional inventory management system is 0.5 rotations, which is greatly improved to 2.1 rotations. I was able to. As a result, inventory costs were significantly reduced. In addition, despite the fact that the standard inventory was reduced at this time, the on-time delivery rate was almost the same as that of the conventional inventory management system. The same value could be maintained.
