[0007]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

<A> Inventory management method. An object of the present invention is an inventory management method in which inventory items are shipped and used according to a user's request, and collected after use.
For example, prepare various kinds of construction materials, ship them according to the request from the site of the construction company that is the customer, collect and recycle the materials when the construction work is completed at the site, and then re- It is a system that is diverted to the target of use. Here, the reproduction is, for example, an operation of dropping the soil, adding a missing dimension, correcting a bend, painting, or closing a hole.

<B> Scheduled collection data. A user who is a customer declares a scheduled collection date and time before use. Therefore, the collection target, the date and time when the collection can be performed, and the like can be known in advance. This is recorded in the scheduled collection data storage device as scheduled collection data.

<C> Scheduled reproduction data. It is expected that some items to be collected on the scheduled date may be deformed or damaged in use. The degree of such deformation or damage, or the ratio of discarding, is grasped as an empirical value from past tabulations depending on the use object.
Therefore, the used scheduled collection items are classified into items that need to be reclaimed, items that cannot be reclaimed, and the like, based on past experience. Further, for the items that need to be regenerated, the expected quantity is recorded by classifying the items into the degree of reproduction from the experience value. In this way, by predicting the amount of data required to be reproduced, predicted reproduction data classified according to the type of reproduction product and the standard is created, and this is recorded in the predicted reproduction data storage device.

<D> Scheduled stock data. Items that should be completed are classified according to the purpose of the target item, such as its type, quality, and standard, and a planned inventory amount is created according to the scheduled completion date. The planned inventory amount for each scheduled date is recorded in the inventory data storage device as inventory data. It is desirable that the planned stock amount always be equal to or larger than the shipping amount from the user and is the minimum amount.

<E> Scheduled request amount data. Requests for shipment arrive from those who wish to use it. The scheduled date of the shipment request is set to a date and time several days to several months in advance.
The scheduled request amount at that date and time is created as scheduled request amount data according to the scheduled date, such as the type, standard, and usage amount, according to the target. The scheduled request amount data is recorded in the scheduled request amount storage device.

<F> Arithmetic unit. From the above process, various data up to several months ahead are stored separately for each date and time. From among them, the numerical values of the planned stock data and the planned required data are output and input to the arithmetic unit. Then, as a result of the calculation, if the planned required amount on a certain day is smaller than the planned stock amount, shipping on that day should be possible. However, if the planned request amount on a certain day is larger than the planned stock amount, there is a shortage in shipping on that day, and the shortage amount can be known.

<G> Adjustment instruction data. When the shortage amount is found as a result of the arithmetic processing step, the data is output as data for increasing the stock amount. For example, it is configured to output as data indicating a new purchase amount or data indicating a borrowing amount according to the shortage amount. Then, even if it takes time to purchase or borrow, it is possible to place an order several months in advance and make it in time for the actual shipping date.

<H> Reproduction priority order data. Apart from the step of outputting an instruction according to the shortage amount, it is also possible to output order instruction data indicating the priority order of the recycled products. This is because the shipping schedule varies, and the time required for reproduction varies depending on the reproduced product. Therefore, priorities are determined according to the planned shipping date and the reproduction time, and the priority is specified. . Then, even if the scheduled shortage occurs at a certain date and time, it is predicted in advance from several months before whether it can be dealt with by changing the order of reproduction of the scheduled reproduction product without purchasing a new one. be able to.

<Re> Rewriting of data. Of course, shipping orders are out of order, and shipment requests several months ahead or several days ahead come apart. On the other hand, the collected product is earlier than the scheduled date if the use of the customer is actually finished, or later than the scheduled date if the use schedule of the customer is prolonged. Various data are sequentially rewritten according to such a future expected request amount and an actual collection amount. If an operation is performed according to the rewriting, the excess or deficiency is calculated, and an instruction is output as needed, an optimal response can be taken in advance, such as determining a new purchase amount or instructing priority reproduction.

[0017]

As described above, the inventory management method of the present invention has the following advantages. <A> In a system in which articles shipped in the past can be returned and reused after recycling, inventory data including a planned collection amount that can be collected in the future can be grasped. Therefore, the amount of stock that can be shipped at an early stage can be grasped, and whether or not shipping is possible at the request of the customer can be immediately determined at the current time. <B> If a shortage occurs in comparison between the planned shipment and the planned stock, a measure to increase the planned stock amount can be taken in advance. Therefore, it can always be shipped according to the customer's request, and business opportunities are not missed. <C> On the other hand, if the amount of shipment to the customer is within the planned inventory amount, it is possible to perform an efficient operation in which the amount of new purchases is minimized and the current inventory amount is maximized. <D> In the case of regenerating the collected products, if the variety is enormous, the determination of the reproduction order has a great influence. For example, if the priority is given to the reproduction and repair of an item that is not required to be shipped, it will only be left for a long period of time. In this regard, according to the management method of the present invention, the varieties to be requested are put out in a list and reproduced in order, so that there is no waste and it is very economical. <E> By the same process as described above, it is possible to quickly identify items that cannot be reproduced and need to be newly purchased, so that a reasonable purchase plan can be made and the overall cost is reduced. Can be done. <F> Especially when dealing with a large number of objects of various types, the above-mentioned economic effects are greatly reflected.
