In addition, the distribution management server 20 may include a storage device for storing data or may store data through a third server (not shown).

The distribution management server 20 obtains the goods release information of the goods released from the factory from the factory reading device 10 or inventory of goods read through the manager terminal 30 at the distribution point visited by the manager included in the distribution path Information can be obtained and the distribution history of each product and the clear inventory of each distribution point can be identified based on the obtained release information and inventory information.

Hereinafter, the configuration of the product distribution management system 100 will be described with reference to FIG. 2. Hereinafter, the product distribution management system 100 may include at least a distribution management server 20 shown in FIG. 1.

The merchandise distribution management system 100 reads tag information from identification tags attached to the merchandise existing at each distribution point and collects inventory information including tag information of the stock products of each distribution point ( 110). Specifically, the inventory information collecting unit 110 includes identification information of an arbitrary distribution point from each manager terminal 30 and tag information read from an identification tag attached to the stock product by the reading device 31 at the distribution point. Can be received. The inventory information collecting unit 110 may store the collected information as inventory information in the inventory information management unit 120 which will be described later.

The inventory information management unit 120 stores the inventory information by storing the inventory information collection unit 110 in association with each other and storing the identification information of the distribution point collected by the manager terminals 30 and a set of tag information read from the distribution point. And manage. At this time, even if each inventory information is related to the same distribution point identification information, it can be managed separately for each time collected as described above.

In addition, the inventory information management unit 120 may update the inventory information in response to the distribution processing request, when the distribution processing request is received from the manager terminal 30. Here, the distribution processing request is a request to update the inventory information of each distribution point online in accordance with the offline distribution of the product, and requests that the product for distribution, return, resale (sale or purchase) be distributed, and process the online record. to be. In more detail, the distribution processing request may be at least one of a delivery processing request, a return processing request, a sales processing request, or a purchase processing request for a product. This distribution processing request may occur in response to one distribution point identification information. That is, it may be a request for processing a product distribution for a specific distribution point.

In addition, the product distribution management system 100 may include a distribution request receiving unit 130 that receives the above-mentioned distribution processing request. The distribution request receiving unit 130 may receive the distribution processing request as described above from the manager terminal 30. Here, the distribution processing request may include tag information read from identification tags attached to products to be delivered, returned, sold or purchased, that is, tag information of a product to be distributed, but is not necessarily so. However, the distribution processing request is used to specify the update target of which distribution branch inventory information should be updated by including the identification information of the distribution branch as described above.

According to the distribution processing request received by the distribution request receiving unit 130, the above-described inventory information management unit 120 processes the delivery of goods for which the distribution processing request does not include the tag information in the inventory information before the update of any distribution point. If it is a request, the tag information of the distribution target product is further included in the inventory information before the update of any distribution point, and if the distribution processing request is a return processing request for the product whose tag information is included in the inventory information before the update of any distribution point. The inventory information can be updated by excluding the tag information of the product to be distributed from the inventory information before updating any distribution point.

In addition, the distribution request receiving unit 130 may receive, in addition to the identification information of any distribution point in the distribution processing request, including the identification information of the transaction, for example, the other party's distribution point of the product, in this case, inventory information management unit ( 120) if the distribution processing request is a sales processing request for a product whose tag information is included in the inventory information before the update, excludes the tag information of the product to be distributed from the inventory information before the update of any distribution point, The information further includes tag information of the product to be distributed, and if the distribution processing request is a purchase processing request for a product not included in the inventory information before the update of any distribution point, the product to be distributed in the inventory information before the update of any distribution point. By including the tag information of the product and excluding the tag information of the product to be distributed from the inventory information of the counterparty's distribution branch. You can update the information. That is, when a resale processing request between two different distribution points is received, the inventory information management unit 120 may update both inventory information of each of the two distribution points.

On the other hand, if at least some of the tag information included in the inventory information before the update for any distribution point is found as tag information of the suspected distribution distribution of goods, the product distribution management system 100 for the product corresponding to the found tag information It may include a suspicious tag detection unit 140 to query the administrator who collected the inventory information before the distribution status.

Here, the suspected distribution of the product is a product that is suspected of offline distribution without leaving an online history by request for distribution processing, for example, a product newly estimated to be reselled from one distribution point to another distribution point or randomly produced It may mean that the goods received at the distribution point of, i.e., the goods that are assumed to have been delivered.

The suspicious tag detection unit 140 specifically collects tag information before the update of the tag information included in the pre-update inventory information of the distribution point, but does not include the tag information that is not included in the previous inventory information of the distribution point of the other distribution point. Compared with the inventory information, if it is confirmed that the tag information included in the inventory information of the other distribution point overlaps, the administrator who collected the inventory information before the update can be queried whether or not to resell the goods corresponding to the duplicate tag information . That is, when the suspicious tag detection unit 140 collects inventory information at an arbitrary distribution point and transmits the inventory information to the inventory information collection unit 110, some of the tag information included in the inventory information collected this time is past. If it is found that it was not included in the inventory information collected at the distribution point and was included in the inventory information of the other distribution point, it can be assumed that the product corresponding to the tag information was resold from the other distribution point to the distribution point. have. In addition, the suspicious tag detection unit 140 may transmit the confirmation of the resale with the information of the products for which the resale is estimated to the manager terminal 30 that collected the inventory information. Accordingly, the manager who visits the distribution point can answer the question by checking whether the distribution point is reselling the product.

At this time, if the manager confirms the resale facts of the products that are requested to confirm whether the resale through the manager terminal 30, it may transmit a resale processing request for the corresponding products to the distribution request receiver 130. In other words, the distribution request receiver 130 may receive a resale processing request as a response to an inquiry about resale. In this case, the resale processing request may be classified into a sales processing request and a purchase processing request according to whether the corresponding distribution point has sold or purchased a product to another distribution point, and the resale processing request may include identification information of the other distribution point. .

In another embodiment, the suspicious tag detection unit 140 may include tag information that is not included in past inventory information of any distribution point collected before inventory information before update among the tag information included in the inventory information before update for any distribution point. Duplicates the tag information included in the shipment information compared to the shipment information, it can be asked to the administrator who collected the inventory information before the update whether the delivery of goods corresponding to the duplicate tag information. That is, the suspicious tag detection unit 140 detects the tag information of the corresponding products when the online distribution processing request is not received in advance for the products that are first shipped to the distribution point after being released from the production site among the inventory information of any distribution point. You can ask the administrator whether or not to deliver.

That is, for example, when the online delivery of goods delivery is not processed, when the manager visits the distribution point and the inventory information collected includes the tag information of the newly delivered goods, suspicious tag detection unit 140 Can detect this and query for delivery. In this case, the distribution request receiver 130 may receive a delivery processing request from the manager terminal 30 as a response corresponding to the inquiry to the manager.

That is, in the embodiment of the present invention, the distribution processing request may be made first before the offline processing is completed, or may be made later after the offline processing is completed. When a request for distribution processing is made later, the above-described suspicious tag detection unit 140 may query the manager by detecting tag information of a product that is estimated to be distributed without an online history. However, when the distribution on the offline is made after the distribution processing request is selectively received, the distribution processing confirmation unit 150, which will be described later, may check whether the products processed as distributed on the online are distributed in correspondence with the online history even on the offline. have.

That is, the product distribution management system 100 uses the inventory information of the distribution branch collected after the stock information of any distribution branch is updated in response to the distribution processing request, and determines whether or not the offline distribution processing corresponds to the distribution processing request. It may further include a distribution processing confirmation unit 150 to confirm.

For example, the distribution processing confirmation unit 150 receives a delivery processing request for some products for a certain distribution point and updates inventory information based on inventory information collected from the distribution point. You can check it. That is, after the delivery processing request is received by designating specific tag information, whether the distribution processing on-line may be verified by checking whether the specific tag information is included in the newly received inventory information at the distribution point.

That is, the distribution processing confirmation unit 150 may check whether or not offline distribution by checking whether at least a certain ratio or more of the tag information of the distribution target products is included or not included in the inventory information received later from the distribution point.

The distribution processing confirmation unit 150 may confirm that the offline distribution is completed when the tag information of the product for which the delivery processing request or the purchase processing request is included in the stock information of the corresponding distribution point. If the tag information of the returned goods processing request or the sale processing request product is not included in the stock information of the corresponding distribution point, the offline distribution may be completed.

Meanwhile, the distribution management server 20 may include a shipment information management unit 160. The shipment information management unit 160 may collect tag information of newly produced goods and manage the shipment information by excluding tag information of the distributed goods from tag information of the newly produced goods.

In other words, when the reading device 10 reads an RFID tag attached to at least one product that is released to be placed at a distribution point, the shipping information management unit 160 may read the tag of the identification tag read from the loading device 10. Information can be obtained as shipping information. And if the information about the distribution history of each tag information included in the delivery information, the shipment information management unit 160 may delete the corresponding tag information from the factory information.

Such shipment information may be used by the suspicious tag detection unit 140 to detect tag information of a product, which is assumed to be newly delivered to an arbitrary distribution point.
