Description
Technical Field
The present disclosure relates to the field of warehousing technologies, and in particular, to an inventory management system and an inventory management method.
Background
Along with the rapid development of information technology, the storage logistics industry can carry goods, goods shelves and the like through intelligent carrying equipment, and human resources are greatly saved.
In practical application, goods in the warehouse are stored in each goods shelf, and after the goods are put into the warehouse, the goods need to be put into the goods shelf and transported to a certain position in the warehouse through the transporting equipment. In the prior art, the position of a shelf in a warehouse is related to the delivery probability of each goods in the shelf, and the greater the sum of the delivery probabilities of each goods in the shelf, the closer the shelf is to a workstation, and the higher the efficiency of a transporting device transporting the goods in the shelf to the workstation. The ex-warehouse probability mentioned here can be used to indicate the possibility of goods ex-warehouse. For example, if a cargo such as mineral water is delivered in a large amount per day, the delivery probability of the cargo is high, whereas for a cargo such as medical equipment, the delivery probability of the cargo is low compared to mineral water because the delivery probability of the cargo is low compared to mineral water.
However, in the prior art, if the stock of a certain goods with a high ex-warehouse probability is large, all the stocks of the goods may be placed at a position close to the workstation, and the goods may occupy most of the area of the warehouse in the area close to the workstation, so that the goods with a low ex-warehouse probability are likely to be placed at a position far from the workstation. If a certain goods with a low ex-warehouse probability needs to be ex-warehouse, the carrying equipment needs to travel a long distance in the process of carrying the goods, and therefore the overall efficiency of carrying the goods in the warehouse by the carrying equipment is low.
Therefore, how to improve the carrying efficiency of the carrying equipment is an urgent problem to be solved.

It is to be understood that the embodiments described are only a few embodiments of the present disclosure, and not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present specification without any creative effort belong to the protection scope of the present specification.
The technical solutions provided by the embodiments of the present description are described in detail below with reference to the accompanying drawings.
The present specification provides an inventory management system, which includes at least one control center, a plurality of inventory receptacles and at least one handling device, wherein the inventory receptacles can store goods and be stored in a warehouse, and the control center can control the handling devices to handle the inventory receptacles to the positions of the inventory receptacles in the warehouse, as shown in fig. 1.
Fig. 1 is a schematic diagram of an inventory management system provided in the present specification.
As can be seen from fig. 1, the inventory management system includes a plurality of inventory containers (e.g., shelves, containers, etc.), when there is a cargo to be delivered, the control center may notify the transporting device to transport the inventory container to a work area corresponding to the warehouse, and accordingly, after the transporting device reaches the location of the inventory container to be transported, the inventory container may be transported from the original location to the work area, and then the cargo to be delivered will be taken out from the inventory container. The work area corresponding to the warehouse mentioned herein refers to an area where a worker performs a task of delivering goods, and the worker can perform a preparation work of delivering goods (for example, taking goods to be delivered from a shelf) in the work area. The work area may be located inside the warehouse as shown in fig. 1 or outside the warehouse.
In practical applications, the goods to be delivered from the stock container can be taken out by the conveying device and conveyed to the working area, without changing the position of the stock container.
The specific form of the control center in fig. 1 may be various, for example, the control center may be a terminal device such as a computer, or may be a server with higher computing power. Further, there may be one control center for controlling the transport facility, or there may be a plurality of control centers, that is, a plurality of control centers cooperate to control a plurality of transport facilities to adjust the position of the stock container.
The specific form of the conveying device for conveying the inventory container can be various, for example, one conveying device is used for jacking the inventory container after reaching the bottom of the inventory container, so that the inventory container is conveyed; a holding fork is arranged on a carrying device, the carrying device can stretch out the holding fork after reaching the position of an inventory container, and then the whole inventory container is dragged to other positions through the holding fork. Also, the present specification does not limit the specific form of the carrying apparatus.
The inventory management system is briefly described above, and the inventory management system provided in the present specification will be described in detail below with the control center as an executive body.
Fig. 2 is a schematic flow chart of an inventory management method in this specification, which specifically includes the following steps:
s201: for each inventory receptacle, a current location of the inventory receptacle in the warehouse is determined as a first inventory location.
S202: and determining the position of the inventory container in the warehouse, which needs to be adjusted, as a second inventory position according to the inventory information currently corresponding to each cargo stored on the inventory container.
In this specification, a warehouse may store a plurality of inventory containers, and the inventory containers may store a plurality of goods, and the inventory containers may be shelves, containers, and the like, capable of storing goods. After the goods are put into the stock container in the warehouse, the control center needs to determine the position where the stock container should be stored in the warehouse and transport the stock container to the position through the transporting equipment.
Based on this, the control center may determine, for each inventory receptacle, a current position of the inventory receptacle in the warehouse as a first inventory position, and determine, according to inventory information currently corresponding to each item stored on the inventory receptacle, a position to which the inventory receptacle needs to be adjusted in the warehouse as a second inventory position. The second inventory location mentioned here is a location in the warehouse where the inventory container should be stored, and the inventory information currently corresponding to the goods may include warehousing information, ex-warehouse information, and the like of the goods, such as warehousing sequence, average ex-warehouse quantity, ex-warehouse sequence, and the like corresponding to the goods.
Further, the control center may determine the heat degree of the basic goods corresponding to each of the goods stored in the stock container, and determine the current delivery priority corresponding to each of the goods stored in the stock container according to the current corresponding stock information of the goods. And determining the heat degree of the current goods corresponding to the goods according to the heat degree of the basic goods and the current delivery priority. Then, the container heat degree corresponding to the inventory container may be determined according to the current cargo heat degree corresponding to each cargo on the inventory container, and the second inventory location may be determined according to the container heat degree. Wherein, the higher the container heat degree corresponding to the inventory container, the closer the distance between the second inventory position and the working area corresponding to the warehouse.
The current delivery priority mentioned here may be used to indicate the priority of delivering the goods in the same goods, and goods with high current delivery priority may be delivered preferentially. The basic goods heat degree corresponding to the goods mentioned here can be determined by the goods corresponding ex-warehouse probability, and the goods ex-warehouse probability is used for representing the possibility of goods ex-warehouse. The ex-warehouse probability of the goods and the basic goods heat of the goods have a positive correlation, that is, if the ex-warehouse probability of the goods is higher, the basic goods heat of the goods is also higher, and if the ex-warehouse probability of the goods is lower, the basic goods heat of the goods is also lower. Of course, the basic goods heat can also be determined by other data, such as the average delivery quantity of the goods, and the positive correlation between the average delivery quantity of the goods and the basic goods heat of the goods can also exist, and the basic goods heat can be specifically set according to actual requirements.
In this specification, the control center may determine the current ex-warehouse priority in various ways. For example, the control center may determine, according to the inventory information currently corresponding to the goods, an inventory section into which the warehousing order corresponding to the goods falls from inventory sections pre-divided for the goods, as a target section, and determine, according to the target section, a current ex-warehouse priority corresponding to the goods, where the ex-warehouse priorities corresponding to different inventory sections are different. It can be seen that this approach requires that each inventory section of the good be pre-divided. The stock interval mentioned here can be set according to actual needs.
Assuming that 1000 identical goods exist, goods from the 1 st warehouse to the 100 th warehouse may be divided into a first stock section, goods from the 101 st warehouse to the 500 th warehouse may be divided into a second stock section, and goods from the 501 st warehouse to the 1000 th warehouse may be divided into a third stock section. The three different stock intervals are corresponding to different delivery priorities, the current delivery priority of the goods in one stock interval is the delivery priority of the stock interval, the current delivery priority of the goods in the first stock interval is the highest, the current delivery priority of the goods in the second stock interval is the next to the current delivery priority of the goods in the third stock interval, and the current delivery priority of the goods in the third stock interval is the lowest. If the current delivery priority of the 50 th item of goods delivered in storage needs to be determined, the control center may determine that the delivery sequence (i.e., 50) of the goods falls into the first storage interval, and therefore, the current delivery priority of the goods is the delivery priority corresponding to the goods in the first storage interval.
In this way, the current ex-warehouse priority of the goods is determined according to the warehousing sequence of the goods, because the goods can be sequentially ex-warehouse according to the warehousing sequence, that is, the goods which are warehoused first are ex-warehouse first, and then the goods which are warehoused are ex-warehouse later. In practical application, if the delivery sequence of the goods is not consistent with the warehousing sequence of the goods (for example, the control center specifies that the delivery sequence of the goods is the production date sequence of the goods, and the goods are not warehoused according to the production date sequence), the current delivery priority of the goods can also be determined according to the delivery sequence of the goods (that is, the warehousing sequence is changed into the delivery sequence).
Besides the above modes, the control center can also determine the current ex-warehouse priority in other modes. For example, the control center may directly determine the current delivery priority of the goods according to the warehousing order of the goods, and assume that there are still 1000 goods, the current delivery priority of the 1 st warehoused goods is the highest, the current delivery priority of the 2 nd warehoused goods is lower, the current delivery priority of the 3 rd warehoused goods is lower, and so on, the current delivery priority of the 1000 th warehoused goods is the lowest. As can be seen from these two examples, the current ex-warehouse priority of the goods may be related to the warehousing order of the goods, i.e., if the goods are warehoused earlier, the current ex-warehouse priority of the goods is higher.
It should be noted that each stock section mentioned above may be set according to actual requirements, and of course, the control center may also divide each stock section in other manners, specifically, the control center may divide each stock section corresponding to the goods according to the average delivery amount corresponding to the goods, that is, the amount of the goods contained in each stock section may be a multiple of the average delivery amount corresponding to the goods. For example, assuming that the goods are mineral water, the control center may determine that the average delivery amount of mineral water is 1000 boxes/day, the quantity of goods in the first stock section may be twice the average delivery amount, i.e., 1000 boxes, the quantity of goods in the second stock section may be twice the average delivery amount, i.e., 2000 boxes, and the quantity of goods in the third stock section may be three times the average delivery amount, i.e., 3000 boxes. Wherein, the multiple of the goods volume in each stock interval compared with the average delivery volume can be set according to the actual requirement.
After the control center determines the heat degree of the basic goods corresponding to the goods and the current ex-warehouse priority, the heat degree of the current goods corresponding to the goods can be determined. The higher the heat degree of the basic goods is, the higher the heat degree of the current goods is, the higher the priority of the current delivery is, and the higher the heat degree of the current goods is. As can be seen, not all of the base shipments with higher heat may have higher current cargo heat, and of these base shipments with higher heat, the shipments with lower current shipment priority may be located further from the work area. For the goods with low heat of the basic goods, the goods are likely to be placed at a position closer to the working area due to the influence of the current delivery priority.
The specific way of determining the heat degree of the current goods corresponding to the goods by the control center can be various. The control center can query the heat weight of the goods corresponding to the current ex-warehouse priority, and determine the heat of the current goods corresponding to the goods according to the queried heat weight and the heat of the basic goods corresponding to the goods. That is to say, in this way, a heat weight is set for each delivery priority of each inventory section, the higher the delivery priority is, the higher the value of the heat weight is, the control center can query the heat weight of the current delivery priority of the goods, and determine the heat of the current goods according to the heat weight and the heat of the basic goods. Of course, in addition to this manner, the control center may also use the sum of the current ex-warehouse priority corresponding to the goods and the base goods heat as the current goods heat corresponding to the goods.
The control center may then determine a container heat corresponding to the inventory container and determine the second inventory location based on the container heat. The control center may use the sum of the heat degrees of the current goods corresponding to the respective goods on the stock container as the container heat degree. Of course, the control center may use the average value of the current heat of the cargo corresponding to each cargo as the container heat. The specific manner in which the control center determines the heat of the container is not limited herein.
S203: and sending a conveying instruction to the conveying equipment according to the first stock position and the second stock position so as to enable the conveying equipment to convey the stock container from the first stock position to the second stock position according to the conveying instruction.
The control center can send a carrying instruction to the carrying equipment according to the first stock position and the determined second stock position. After receiving the conveying instruction sent by the control center, the conveying equipment can convey the inventory container from the first inventory position to the second inventory position according to the conveying instruction.
In practical applications, the control center may directly rank the inventory receptacles from high to low based on their receptacle heat levels. After sorting the inventory receptacles, the control center may determine a second inventory location for each inventory receptacle according to the order in which the inventory receptacles are sorted. That is, the higher ranked inventory receptacles may be placed closer to the work area corresponding to the warehouse, and the lower ranked inventory receptacles may be placed farther from the work area corresponding to the warehouse. Of course, in addition to this, the control center may divide the warehouse into several areas and determine the area where the inventory receptacles should be located according to their receptacle heat, as shown in fig. 3.
Fig. 3 is a schematic diagram of a warehouse zoning area provided in the present specification.
In fig. 3, the dotted rectangle indicates a plurality of areas for storing the inventory receptacles divided in the warehouse, and it can be seen that area 1 is closest to the work area, area 2 is farther from the work area than area 1, and area 3 is farthest from the work area. The heat intervals for the area 1, the area 2, and the area 3 may be set in advance. For example, the preset heat level interval for the area 1 is [10,7], the preset heat level interval for the area 2 is [6,4], and the preset heat level interval for the area 3 is [3,1 ].
If the control center determines that the container heat degree corresponding to the inventory container a is 8, the container heat degree corresponding to the inventory container a falls within the heat degree interval of the area 1, so the control center may determine that the position of the inventory container a should be located in the area 1, and control the conveying device to convey the inventory container a to the area 1. The container heat corresponding to the stock container B is 5, and the container heat corresponding to the stock container B falls within the heat range of the area 2, so that the control center can determine that the position of the stock container B is located within the area 2, and control the conveying device to convey the stock container B to the area 2. The container heat corresponding to the inventory container C is 2, and it can be determined that the container heat corresponding to the inventory container C falls within the heat range of the area 3, so the control center can determine that the position of the inventory container C is located in the area 3, and control the conveying device to convey the inventory container C to the area 3.
It should be noted that the current cargo heat of the cargo is not constant, and the current cargo heat of the cargo can be changed along with the continuous consumption of the cargo. For the same goods, after the goods in the stock section with the highest delivery priority are gradually consumed, the control center can improve the current goods heat degree of the goods in the stock section with the lower delivery priority, so that the goods with the improved goods heat degree can be supplemented to a position close to the working area, the distance for carrying the goods by the carrying equipment can be reduced when the goods are subsequently delivered out, and the carrying efficiency of the carrying equipment is improved.
Specifically, if the control center determines that the number of the goods is not less than the first set number for each kind of goods, the current delivery priority corresponding to the remaining goods may be adjusted to obtain the adjusted delivery priority corresponding to the goods. Then, the control center may determine, for each inventory receptacle, if it is determined that the goods are stored in the inventory receptacle, the receptacle heat corresponding to the inventory receptacle again according to the adjusted delivery priority corresponding to the goods. The first set number can be set according to actual requirements.
That is, for a kind of goods, if a large number of such goods are delivered, the stock section where the remaining goods are located should be adjusted to the stock section corresponding to the goods that have been delivered, which inevitably causes the current delivery priority of the remaining goods to change. Therefore, the control center needs to adjust the current delivery priority of the remaining goods. It is emphasized that the first set amount mentioned here is set only for the delivery of one kind of goods. The first set amount set for different kinds of goods may be different.
The control center needs to query the heat weight of each kind of goods stored in the inventory container, which corresponds to the adjusted delivery priority of the goods, and re-determines the heat of the current goods corresponding to the goods according to the heat weight of the adjusted delivery priority and the heat of the basic goods corresponding to the goods, and then re-determines the heat of the containers corresponding to the inventory container according to the re-determined heat of the current goods corresponding to the goods and the heat of the current goods corresponding to other goods stored in the inventory container. That is, after the delivery priority of the goods is increased, the control center needs to determine the current goods heat of the goods according to the changed delivery priority by the method for determining the goods heat, and then determines the container heat of the whole inventory container.
Then, the control center may determine, according to the determined container heat corresponding to the inventory container, a position to which the inventory container needs to be adjusted in the warehouse as a third inventory position, where the third inventory position is a position to which the inventory container is adjusted after a period of time elapses after the goods in the inventory container are warehoused, and is not a position of the inventory container when the goods are just warehoused. Thus, the control center can send a conveying instruction to the conveying device which does not perform the conveying task according to the third stock position and the first stock position (i.e., the position of the stock container in the warehouse), so that the conveying device conveys the stock container from the first stock position to the third stock position. That is, after the container heat of the entire stock container is raised, the control center needs to specify a new position of the stock container according to the container heat of the stock container and transport the stock container to the new position by the transport device, as shown in fig. 4A and 4B.
Fig. 4A and 4B are schematic diagrams illustrating changing the position of an inventory receptacle provided herein.
In fig. 4A, the inventory containers G, H, I, J, K all have the same item a, and the item a stored in the inventory container J, K has the highest current delivery priority, so the control center determines that the item a stored in the inventory container J, K has a high heat value. The control center determines that the container heat degree is high based on the goods heat degrees of all the goods in the two inventory containers, and therefore the inventory container J, K is placed in an area closer to the work area. While item a on inventory container H, I is of lower current outbound priority than item a on inventory container J, K and the control center determines that the container heat of inventory container H, I is low and therefore both inventory containers are placed in the in-warehouse area that is further from the work area. While the current shipment priority of the goods a stored on the stock container G, which is placed in the area farthest from the work area, is the lowest.
Fig. 4B shows the respective stock containers in the warehouse after a large number of goods a are taken out of the warehouse for a while. Here, the goods a stored in the stock container H, I, J, K are all delivered, and therefore, the current delivery priority of the remaining goods a stored in the stock container G is increased, which results in that the current cargo heat of all the goods a stored in the stock container G is increased, and further the container heat of the stock container G is increased, and the position of the stock container G redetermined by the control center is located in the area closest to the work area, and therefore, the stock container G is moved to the position in fig. 4B, which is the position of the stock container K before, and it can be seen that this position is very close to the work area. The control center determines again that the container heat levels of the four inventory containers are all reduced to some extent according to the current cargo heat levels of the remaining cargo in the inventory container H, I, J, K, so that the positions of the four inventory containers in the warehouse are all adjusted to some extent, and it can be seen that the distances from the four inventory containers to the working area are all longer than before.
It should be noted that the control center may cause the conveying apparatus to perform the task of conveying the inventory receptacles in this specification at the time of a logistics valley (i.e., when the conveying apparatus does not need to convey too many cargos). Specifically, the control center can determine the current ex-warehouse priority corresponding to the goods when the goods with the quantity not exceeding the second set quantity are ex-warehouse, and then determine the current goods heat of the goods according to the current ex-warehouse priority corresponding to the goods, so that the container heat of the inventory container is determined to determine the container position of the inventory container, and a carrying instruction for carrying the inventory container is sent to the carrying equipment. The second set number can be set according to actual conditions. The second set amount is set for the delivery amount of all the goods.
If there are only a few items (not exceeding the second set number) in the warehouse, then it is indicated that the handling equipment in the warehouse may have to perform fewer handling tasks. In this case, the control center can determine the container heat of the stock container again at any time and adjust the container position of the stock container.
In addition to the above manner, after the control center redetermines the heat degree of the current goods corresponding to the goods, the control center can also replenish the remaining goods to the inventory containers closer to the working area one by one through the carrying equipment without directly carrying the whole inventory containers through the carrying equipment. After determining the current cargo heat degree of the cargo, the control center can inform the carrying equipment to carry the remaining cargo to the inventory container matched with the determined current cargo heat degree.
For example, assuming that the container heat corresponding to the stock container is an average value of the cargo heat of the cargo on the stock container, the control center may determine the stock container whose container heat is not much different from the newly determined current cargo heat of the cargo, and notify the carrying apparatus to carry the cargo to the stock container.
In this specification, the control center may control the location of inventory receptacles in two dimensions, the base cargo heat of the cargo and the ex-warehouse priority. The dimension of increasing the delivery priority can ensure that the goods with lower heat of the basic goods can be placed at a position close to the working area, and for the goods with higher heat of the basic goods, if part of the goods can not be delivered in a short time, the goods can be placed at a position far away from the working area. This mode can carry out reasonable division to the goods position that the goods was located, and the goods that are out of stock sooner can be distributed to the goods position that is nearer apart from the work area, and the goods that are out of stock sooner can be distributed to the goods far away apart from the work area. Compared with the prior art, the method can improve the conveying efficiency of the conveying equipment to a certain extent.
