Description

Inventory management system and inventory management method

The embodiments of the present invention relate to the technical field of warehousing, and in particular, to an inventory management system and an inventory management method.

With the rapid development of information technology, the warehousing and logistics industry can use intelligent handling equipment to move goods, shelves, etc., which greatly saves human resources.

In practical applications, the goods in the warehouse are stored in each shelf. After the goods are put into the warehouse, the goods need to be put into the shelf and the shelf is transported to a certain position in the warehouse by the handling equipment. In the prior art, the position of the shelf in the warehouse is related to the delivery probability of each product in the shelf. The greater the sum of the delivery probabilities of the goods in the shelf, the closer the shelf is to the workstation, and the handling equipment carries the goods in the shelf. The efficiency to the workstation is also higher. The outbound probability mentioned here can be used to represent the possibility of goods outbound. For example, if mineral water has a large daily outbound volume, the probability of outbound goods is also high. For medical equipment, compared with mineral water, the daily outbound volume of this goods is less. Therefore, the delivery probability of this product is lower than that of mineral water.

However, in the existing technology, if a certain kind of goods with a high probability of outbound has a large inventory, all the inventory of this kind of goods may be placed at a position closer to the workstation, and this kind of goods will occupy the space in the warehouse that is closer to the workstation. Most of the area, so that the goods with a low probability of being out of the warehouse are likely to be placed far away from the workstation. Then, once a certain cargo with a low delivery probability needs to be delivered from the warehouse, the handling equipment needs to travel a long distance in the process of handling the goods, which leads to the low overall efficiency of the handling equipment in handling goods in the warehouse.

Therefore, how to improve the handling efficiency of the handling equipment is an urgent problem to be solved.

Compared with the existing technology, the control center can only control the position of the inventory container through the probability of goods leaving the warehouse. This solution can improve the handling to a certain extent. Equipment handling efficiency.

In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions of the embodiments of the present invention in conjunction with specific embodiments of the present invention and corresponding drawings. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention.

The technical solutions provided by various embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

An embodiment of the present invention provides an inventory management system. The inventory management system includes at least one control center, several inventory containers and at least one handling equipment. The inventory containers can store goods and be stored in the warehouse. The control center can control each The handling equipment moves the inventory container to the location where the inventory container should be in the warehouse, as shown in Figure 1.

Fig. 1 is a schematic diagram of an inventory management system provided by an embodiment of the present invention.

As can be seen from Figure 1, the inventory management system contains several inventory containers (such as shelves, containers, etc.), and when there are goods that need to be delivered from the warehouse, the control center can notify the handling equipment to move the inventory containers to the corresponding working area of the warehouse Correspondingly, after the handling equipment arrives at the location of the storage container that needs to be moved, it can move the storage container from the original position to the work area, and then the goods that need to be out of the warehouse will be taken out of the storage container. Wherein, the working area corresponding to the warehouse mentioned here refers to the area where the staff performs the task of goods out of the warehouse, and the staff can prepare for the goods out of the warehouse in this work area (for example, take out the goods that need to be out of the warehouse from the shelf). The working area can be located inside the warehouse as shown in Figure 1, or outside the warehouse.

Of course, in practical applications, the goods that need to be released from the storage container can also be taken out from the storage container by the handling equipment, and these goods can be transported to the working area, while the position of the storage container itself does not change.

Wherein, the control center in FIG. 1 may have various specific forms, for example, it may be a terminal device such as a computer, or it may be a server with higher computing power. Further, there may be one control center for controlling the handling equipment, or there may be multiple control centers, that is, multiple control centers coordinately control multiple handling equipment to adjust the positions of the inventory containers.

The specific form of the handling equipment used to carry the storage container can also have many kinds. For example, a kind of handling equipment is to lift the storage container after reaching the bottom of the storage container, and then realize the handling of the storage container; a kind of handling equipment is provided with a holding fork, After the handling equipment reaches the position of the storage container, it can extend the holding fork, and then drag the entire storage container to other positions through the holding fork. Likewise, the embodiment of the present invention does not limit the specific form of the transport equipment.

The above briefly describes the inventory management system, and the following will take the control center as the executive body to describe the inventory management system provided by the embodiment of the present invention in detail.

Fig. 2 is a schematic flowchart of an inventory management method in an embodiment of the present invention, which specifically includes the following steps.

S201: For each inventory container, determine the current location of the inventory container in the warehouse as the first inventory location.

S202: According to the current inventory information corresponding to each item stored in the inventory container, determine a position to be adjusted to of the inventory container in the warehouse as a second inventory location.

In the embodiment of the present invention, several inventory containers can be stored in the warehouse, and several pieces of goods can be stored in the inventory containers. The inventory containers mentioned here can refer to containers that can store goods such as shelves and cargo boxes. After the goods are put into the storage container, the control center needs to determine the location where the storage container should be stored in the warehouse, and move the storage container to the location through the handling equipment.

Based on this, the control center can determine the current location of the inventory container in the warehouse as the first inventory location for each inventory container, and determine the current location of the inventory container according to the current inventory information corresponding to each item stored on the inventory container. The position to be adjusted in the warehouse is used as the second stock position. The second inventory location mentioned here is the location where the inventory container should be stored in the warehouse. The current inventory information corresponding to the goods may include the goods’ inbound information, outbound information, etc., for example, the goods’ corresponding inbound sequence, average Outbound quantity, outbound order, etc.

Further, the control center can determine the heat of the basic goods corresponding to each goods on the inventory container, and for each kind of goods stored on the inventory container, according to the current corresponding inventory information of the goods, determine the current outbound priority corresponding to the goods . Therefore, the current cargo heat corresponding to the cargo is determined according to the basic cargo heat and the current outbound priority. Then, the container heat corresponding to the inventory container can be determined according to the current goods heat corresponding to each goods on the inventory container, and the above-mentioned second inventory position can be determined according to the container heat. Wherein, the higher the temperature of the container corresponding to the inventory container is, the closer the distance between the second inventory location and the corresponding working area of the warehouse is.

The current outbound priority mentioned here can be used to indicate the order in which the goods are outbound among the same goods, and goods with a higher outbound priority may be outbound first. The basic cargo heat corresponding to the goods mentioned here can be determined by the corresponding delivery probability of the goods, and the delivery probability of the goods is used to indicate the possibility of the delivery of the goods. There is a positive correlation between the delivery probability of the goods and the basic goods heat of the goods, that is, the higher the goods delivery probability, the higher the basic goods heat of the goods, and the lower the goods delivery probability, the goods The lower the popularity of the basic cargo. Of course, the basic cargo popularity can also be determined by other data, such as the average delivery volume of goods, and there is also a positive correlation between the average delivery volume of goods and the basic cargo popularity of the goods, which can be set according to actual needs.

In the embodiment of the present invention, there may be multiple ways for the control center to determine the current warehouse-out priority. For example, according to the current inventory information corresponding to the goods, the control center can determine the inventory interval in which the order of warehousing corresponding to the goods falls into from the inventory intervals pre-divided for the goods as the target interval, and according to the target interval , to determine the current outbound priority corresponding to the goods, and the outbound priority corresponding to different inventory intervals is different. It can be seen that this method needs to pre-divide the inventory intervals of the goods. The inventory range mentioned here can be set according to actual needs.

Assuming that there are 1,000 pieces of the same goods, the first inventory interval can be divided from the 1st incoming goods to the 100th incoming goods, and the first inventory interval can be divided from the 101st incoming goods to the 500th incoming goods. The two inventory intervals, from the 501st incoming goods to the 1000th incoming goods can be divided into the third inventory interval. These three different stock intervals have different stock-out priorities. The current stock-out priority of the goods in an stock area is the stock-out priority of the stock area, and the current stock-out priority of the goods in the first stock area is the highest. The current delivery priority of the goods in the second inventory section is next, and the current delivery priority of the goods in the third inventory section is the lowest. If it is necessary to determine the current outbound priority of the 50th inbound goods, the control center can determine that the inbound order of the goods (that is, 50) falls into the first inventory interval, so the current outbound priority of the goods is this The delivery priority corresponding to the goods in the first inventory section.

In this method, the current priority of goods out of the warehouse is determined according to the order of goods in, because the goods can be out of the warehouse in sequence according to the order of inbound, that is, the goods that enter the warehouse first are out of the warehouse, and the goods that are in the warehouse last are out of the warehouse. In practical applications, if the order of the goods out of the warehouse is inconsistent with the order of the goods in the warehouse (for example, the control center stipulates that the order of goods out of the warehouse is the order of the production date of the goods, but the goods are not put into the warehouse in the order of the production date), you can also pass the goods The stock-out sequence (that is, replace the above-mentioned stock-in sequence with the stock-out sequence) determines the current stock-out priority of the outgoing goods.

In addition to the above methods, the control center can also determine the current outbound priority through other methods. For example, the control center can directly determine the current delivery priority of the goods according to the order of the goods in the warehouse. Assuming that there are still 1,000 goods, the current delivery priority of the first delivery is the highest, and the current delivery priority of the second delivery is Lower, the current outbound priority of the third incoming goods is lower, and so on, the current outbound priority of the 1000th incoming goods is the lowest. It can be seen from these two examples that the current delivery priority of the goods may be related to the storage order of the goods, that is, if the goods are stored earlier, the current delivery priority of the goods is also higher.

It should be noted that the inventory intervals mentioned above can be set according to actual needs. Of course, the control center can also divide the inventory intervals in other ways. Specifically, the control center can divide according to the average outbound quantity of the goods. Each inventory section corresponding to the goods, that is, the quantity of goods contained in each inventory section may be a multiple of the average outbound quantity corresponding to the goods. For example, assuming that the goods are mineral water, the control center can determine that the average outbound quantity of mineral water is 1000 boxes/day, then the quantity of goods in the first inventory interval can be double the average outbound quantity, that is, 1000 boxes, and the second The quantity of goods in the inventory interval can be twice the average outbound quantity, that is, 2,000 boxes, and the quantity of goods in the third inventory interval can be three times the average outbound quantity, that is, 3,000 boxes. Wherein, the multiple of the quantity of goods in each inventory range compared to the average outbound quantity can be set according to actual demand.

After the control center determines the basic cargo heat corresponding to the cargo and the current outbound priority, it can determine the current cargo heat corresponding to the cargo. Among them, the higher the popularity of the basic goods, the higher the popularity of the current goods, the higher the priority of the current outbound warehouse, and the higher the popularity of the current goods. It can be seen from this that, for the goods with high popularity of basic goods, not all goods of this kind have high current goods heat. Among the goods with high heat of basic goods, those with low priority This kind of goods may be placed far away from the working area. For the goods with low heat of the basic goods, it is also possible to be placed closer to the working area due to the influence of the current outbound priority.

There may be multiple specific ways for the control center to determine the current cargo temperature corresponding to the cargo. Among them, the control center can query the heat weight of the goods corresponding to the current outbound priority, and determine the current heat of the goods corresponding to the goods according to the heat weights obtained from the query and the heat of the basic goods corresponding to the goods. That is to say, this method is to set a heat weight for the stock-out priority of each inventory interval. The higher the stock-out priority, the higher the value of the heat weight, and the control center can query the current stock-out priority of the goods. heat weight, and determine the current heat of the goods based on the heat weight and the heat of the basic goods. Of course, in addition to this method, the control center can also use the sum of the current delivery priority corresponding to the cargo and the basic cargo heat as the current cargo heat corresponding to the cargo.

Then, the control center can determine the temperature of the container corresponding to the storage container, and determine the above-mentioned second storage location according to the temperature of the container. Wherein, the control center may use the heat sum of the current goods heat corresponding to each goods on the inventory container as the container heat. Of course, the control center can also use the average value of the current heat of goods corresponding to each goods as the heat of the container. The specific way for the control center to determine the temperature of the container is not limited here.

S203: Send a transport instruction to the transport device according to the first stock position and the second stock position, so that the transport device transports the stock container from the first stock position according to the transport command to the second inventory location.

The control center may send a handling instruction to the handling equipment according to the first inventory location and the determined second inventory location. After the transport equipment receives the transport instruction sent by the control center, it can transport the inventory container from the first inventory position to the second inventory position according to the transport instruction.

In practical application, the control center can directly sort the storage containers according to the container heat of each storage container from high to low. After the storage containers are sorted according to the container heat, the control center can determine the second storage position of each storage container according to the order of the storage containers based on the container heat. For example, inventory containers with a higher ranking may be placed closer to the corresponding working area of the warehouse, and lower-ranking inventory containers may be placed at positions farther from the corresponding working area of the warehouse. Of course, in addition to this method, the control center can also divide the warehouse into several areas, and determine the area where the inventory container should be located according to the container heat of the inventory container, as shown in Figure 3.

Fig. 3 is a schematic diagram of dividing warehouses into regions provided in an embodiment of the present invention.

In Figure 3, the dotted rectangles indicate the areas divided into storage containers in the warehouse. It can be seen that area 1 is the closest to the working area. Compared with area 1, area 2 is farther away from the working area, and area 3 is farther away from the working area. furthest. Heat ranges for Area 1, Area 2, and Area 3 can be preset. For example, the preset popularity interval for area 1 is [10,7], the preset popularity interval for area 2 is [6,4], and the preset popularity interval for area 3 is [3,1].

Assuming that the control center determines that the container heat corresponding to inventory container A is 8, then the container heat corresponding to the inventory container A falls within the heat range of area 1, so the control center can determine that the location of the inventory container A should be in area 1 and control the handling equipment to transport the inventory container A to area 1. The container heat corresponding to inventory container B is 5, and the container heat corresponding to inventory container B falls within the heat range of area 2, so the control center can determine that the location of inventory container B is in area 2, and control the handling equipment to place Inventory container B is moved to zone 2. The container heat corresponding to inventory container C is 2, and it can be determined that the container heat corresponding to inventory container C falls within the heat range of area 3, so the control center can determine that the location of inventory container C is in area 3, and control the handling The equipment transports the inventory container C to zone 3 .

It should be noted that the current cargo heat of the goods is not static. As the goods are continuously consumed, the current heat of the goods can be changed. For the same goods, when the goods in the inventory area with the highest priority of the outbound warehouse are gradually consumed, the control center can increase the current goods heat of the goods in the inventory area with the lower outbound priority, so that the The goods can be replenished to a position closer to the working area, so that when such goods are subsequently out of the warehouse, the distance for the handling equipment to carry the goods can be reduced, so as to improve the handling efficiency of the handling equipment.

In some embodiments, if the control center determines that no less than the first set quantity of the goods are out of the warehouse for each kind of goods, the current outbound priority corresponding to the remaining goods can be adjusted to obtain the adjusted outbound order corresponding to the goods. priority. Then, for each inventory container, if it is determined that the goods are stored in the inventory container, the control center can re-determine the container heat corresponding to the inventory container according to the adjusted outbound priority corresponding to the goods. Wherein, the first set quantity can be set according to actual needs.

That is, for a kind of goods, if a large number of such goods are out of the warehouse, the inventory interval of the remaining goods should be adjusted to the inventory interval corresponding to the goods that have already been out of the warehouse, which will inevitably lead to the current outbound priority of the remaining goods. Variety. Therefore, the control center needs to adjust the current delivery priority of the remaining goods. It is worth emphasizing that the first set quantity mentioned here is only set for the outbound quantity of one kind of goods. The first set quantity set for different kinds of goods may be different.

Among them, the control center needs to find out the heat weight of the goods corresponding to the adjusted outbound priority for each kind of goods stored in the inventory container, and according to the heat weight of the adjusted outbound priority and the heat of the basic goods corresponding to the goods, re- Determine the current heat of the goods corresponding to the goods, and then re-determine the container heat corresponding to the inventory container according to the re-determined current heat of the goods corresponding to the goods and the current heat of goods corresponding to other goods stored on the inventory container. That is to say, after increasing the priority of the goods out of the warehouse, the control center needs to re-use the method of determining the heat of the goods provided above to determine the current heat of the goods out of the warehouse according to the changed priority of the goods out of the warehouse, and then determine the inventory container. Overall container heat.

Then, the control center can determine the position that the storage container needs to adjust to in the warehouse according to the re-determined container heat corresponding to the storage container, as the third storage position, wherein the third storage position refers to the storage container. The position to which the inventory container is adjusted after a period of time after the goods are put into storage, rather than the position of the inventory container when the goods were first put into the warehouse. Therefore, according to the third inventory location and the first inventory location (that is, the current location of the inventory container in the warehouse), the control center can send a handling instruction to the handling equipment that has not performed the handling task, so that the handling equipment will use the inventory container Handling from the first inventory location to the third inventory location. That is to say, after the overall container heat of the inventory container increases, the control center needs to determine the new location of the inventory container according to the container heat of the inventory container, and transport the inventory container to the new location through the handling equipment, as shown in Figures 4A and 4B Show.

4A and 4B are schematic diagrams of changing the position of an inventory container provided by an embodiment of the present invention.

In Fig. 4A, the same kind of goods a are stored on the storage containers G, H, I, J, and K, and the current delivery priority of the goods a stored on the storage containers J and K is the highest, so the control center determines that the storage containers J, The heat of cargo a stored on K is relatively high. The temperature of the container determined by the control center according to the heat of all the goods in the two storage containers is relatively high, so the storage containers J and K are placed in an area closer to the working area. However, the current outbound priority of the goods a on the inventory containers H and I is lower than that of the goods a on the inventory containers J and K, and the control center determines that the container heat of the inventory containers H and I is relatively low, so the two Inventory containers are placed in areas within the warehouse that are farther from the work area. The current outbound priority of the goods a stored on the inventory container G is the lowest, and the inventory container G is placed in the area farthest from the working area.

Fig. 4B shows the situation of each inventory container in the warehouse after a period of time after a large amount of goods a is out of the warehouse. Among them, the goods a stored on the inventory containers H, I, J, and K are all out of the warehouse, so the current outbound priority of the remaining goods a stored on the inventory container G is increased, resulting in all goods a on the inventory container G The current heat of the goods is increased, which in turn increases the container heat of the inventory container G, and the position of the inventory container G re-determined by the control center is located in the area closest to the working area. Therefore, the inventory container G is transported to Figure 4B The position, which was previously the position of the inventory container K, can be seen that this position is very close to the working area. And the control center re-determines that the container heat of these four inventory containers has dropped to a certain extent according to the current goods heat of the remaining goods in the inventory containers H, I, J, and K, so the positions of these four inventory containers in the warehouse All have been adjusted to a certain extent. It can be seen that the distance between the four inventory containers and the working area is farther than before.

It should be noted that the control center can make the handling equipment perform the task of moving the inventory container in the embodiment of the present invention when the logistics is low (that is, when the handling equipment does not need to carry too many goods). Specifically, the control center can determine the current outbound priority of the outbound goods when the outbound goods do not exceed the second set quantity, and then determine the current heat of the outbound goods according to the current outbound priority of the goods, so as to determine the outbound inventory The container temperature of the container is used to determine the container position of the inventory container, and a handling instruction to move the inventory container is sent to the handling equipment. Wherein, the second set quantity can be set according to actual conditions. The second set quantity is set for the outbound quantities of all goods.

If there are only fewer goods (not exceeding the second set quantity) out of the warehouse, it means that the handling equipment in the warehouse may need to perform fewer handling tasks. In this case, the control center can re-determine the container heat of the storage container at any time, and adjust the container position where the storage container should be located.

In addition to the above methods, after the control center re-determines the current cargo heat corresponding to the cargo, it can also replenish the remaining cargo to the inventory container that is closer to the work area through the handling equipment one by one, without directly transporting the entire cargo through the handling equipment. Stock container. Wherein, the control center may, after determining the current temperature of the goods, notify the handling equipment to move the remaining goods into the inventory container that matches the determined current temperature of the goods.

For example, assuming that the container heat corresponding to the inventory container is the average value of the cargo heat of the goods on the inventory container, the control center can determine the inventory container whose container heat is not much different from the re-determined current cargo heat of the goods, and The handling equipment is notified to move the goods to the inventory container.

In the embodiment of the present invention, the control center can control the position of the inventory container according to the two dimensions of the basic goods heat and the priority of the goods out of the warehouse. Adding the dimension of delivery priority can make the goods with low heat of the basic goods be placed closer to the work area, and for the goods with high heat of the basic goods, if some of the goods are in a short time If it is not out of the warehouse, it may be placed far away from the working area. This method can reasonably divide the cargo space where the goods are located. The goods that leave the warehouse quickly can be allocated to the cargo space that is closer to the working area, and the goods that leave the warehouse slowly can be allocated to goods that are farther away from the working area. . Therefore, compared with the prior art, the method can improve the handling efficiency of the handling equipment to a certain extent.
