Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present disclosure with reference to the accompanying drawings in the embodiments of the present disclosure. Apparently, the described embodiments are only some of the embodiments of the present disclosure, not all of them. The following description of at least one exemplary embodiment is merely illustrative in nature and in no way intended as any limitation of the disclosure, its application or uses. Based on the embodiments in the present disclosure, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present disclosure.

The present disclosure provides an inventory scheduling method, which is applicable to the scenario where the shelves in the unmanned warehouse are multi-deep shelves. It will be described below in conjunction with FIG. 2 .

Fig. 2 is a flowchart of some embodiments of the inventory scheduling method of the present disclosure. As shown in FIG. 1, the method of this embodiment includes: steps S202-S206.

In step S202, the storage aisle and the storage shelf layer in the storage aisle are determined for the container to be stored.

After the inbound goods are determined, the intelligent production scheduling system can generate warehousing tasks for the inbound goods, and recommend the box type of the container according to the information of the goods. For example, small goods and large goods correspond to different box types. After the box type is determined, the intelligent production scheduling system will send the task to the storage workstation, and at the same time, the goods and the corresponding type of container will also be delivered to the storage workstation, and the robot or staff will pack the goods delivered to the workstation. And verify the storage quantity, etc. After the goods are loaded, the boxes to be put into storage are put on the conveyor line, and the weight and height of the boxes to be put into storage can be inspected on the conveyor line to see if they are qualified. Further, it is possible to carry out information identification on the cargo box to be stored, for example, use a BCR (Bar Code Reader) to scan the barcode on the cargo box, etc. The barcode can include information such as cargo identification and quantity. Then, the intelligent production scheduling system initiates the task of aisle and shelf layer to be recommended according to the information of the container to be stored, and further recommends the relevant empty storage space in the determined shelf layer as the final storage space for the container to be stored. The intelligent production scheduling system sends the warehousing tasks to the corresponding various hardware devices, such as shuttle robots, elevators, etc. After receiving the recommended storage space from the intelligent production scheduling system, various hardware equipment will cooperate with the storage boxes to be stored sent to the appropriate storage location.

In some embodiments, the storage aisle is determined for the cargo boxes to be stored according to the distribution of the cargo boxes in each aisle, the load situation and the distance from the aisle to the entrance of the shelf area.

Since the information of the goods stored in each container can be obtained, the container associated with the container to be put into storage in each lane can be determined. The container associated with the container to be put into storage is, for example, a container in which the same or related goods are stored in the container to be put into storage. The relevance of goods can be determined according to the probability that goods are shipped together, for example. For example, by counting the ratio of any two goods appearing in the same order in the preset number of orders, when the ratio is greater than a threshold, it is determined that the two goods are associated.

The first weight of the lane can be set for the lane according to the distribution of the boxes associated with the boxes to be put into storage in each lane. The fewer boxes associated with the boxes to be put into storage, the greater the first weight of the aisle. The second weight of the roadway can be set for the roadway according to the load situation of each roadway, and the load situation includes the number of containers already in the storage position and allocated to the roadway. The greater the load, the greater the second weight of the roadway. The third weight of the lane can be set for the lane according to the distance from the lane to the entrance of the shelf area. The greater the distance from the aisle to the entrance of the shelf area, the greater the third weight of the aisle. Add the above three weights corresponding to the roadway, and use the roadway with the largest final result as the storage roadway.

It can be seen from the above embodiments that, under the same other conditions, the more containers are associated with the containers to be stored, the lower the probability that the lane will be selected as the storage lane. In this way, the associated cargo boxes can be dispersed as much as possible, and it is avoided that the cargo boxes cannot be unloaded in time because the cargo boxes are piled up in a lane, or the lane where the cargo boxes are located is full of outbound tasks. Under other conditions being the same, the smaller the load of the roadway, the higher the probability of the roadway being selected as the storage roadway. In this way, the goods can be avoided as far as possible from being stored in one lane, and cannot be released in time. Under the same other conditions, the greater the distance from the laneway to the entrance of the shelf area, the higher the probability of the laneway being selected as the storage laneway. Since the conveyor line generally enters the storage from the shelf area and passes through each lane in turn, if most of the cargo boxes to be stored are stored in the lane with the closest distance to the entrance of the shelf area, the cargo boxes to be stored will be piled up in this lane. And other cargo boxes cannot be transported to the roadway with a long distance. Therefore, it is possible to improve the efficiency of storage by prioritizing the storage of the boxes to be stored in the aisle with a long distance.

The multiple weights corresponding to the above roadways can be set to different values according to actual needs. For example, the distance from the aisle to the entrance of the shelf area is used as a higher priority selection condition, and the value range of the third weight of the aisle can be set larger than that of the other two weights.

In some embodiments, the storage aisle is determined for the boxes to be stored according to the distribution of the boxes in the shelf layer, the load situation and the height of the shelf layer.

The first weight of the shelf layer can be set for the shelf layer according to the distribution of the boxes associated with the boxes to be put into storage in each shelf layer. The fewer boxes associated with the boxes to be put into storage, the greater the first weight of the shelf layer. The second weight of the shelf layer can be set for the shelf layer according to the load situation of each shelf layer, and the load situation includes the number of containers already in the storage space and allocated to the shelf layer. The greater the load, the greater the second weight of the shelf layer. The third weight of the shelf layer can be set for the shelf layer according to the height of the shelf layer. The smaller the height, the greater the third weight of the shelf layer. Add the above three weights corresponding to the shelf layer, and use the shelf layer with the largest final result as the storage shelf layer.

It can be seen from the above embodiments that, under the same other conditions, the more boxes are associated with the boxes to be put into storage, the lower the probability that a shelf layer is selected as a shelf layer to be put into storage. In this way, the associated cargo boxes can be dispersed as much as possible, so as to prevent the cargo boxes from being out of the warehouse in time because the cargo boxes are piled up on a shelf layer, or the shelf layer where the cargo boxes are located is full of outbound tasks. Under other conditions being the same, the smaller the load on the shelf layer, the higher the probability that the shelf layer will be selected as the storage shelf layer. In this way, the goods can be avoided as far as possible from being stored on one shelf layer and cannot be released in time. When other conditions are the same, the smaller the height of the shelf layer, the higher the probability of the shelf layer being selected as the storage shelf layer. Try to store the goods on the lower shelf layer to improve the efficiency of storage and delivery.

The multiple weights corresponding to the above shelf layers can be set to different values according to actual needs. For example, the box distribution of the shelf layer is used as a higher-priority selection condition, and the value range of the first weight of the shelf layer can be set to be larger than that of the other two weights.

In step S204, the available storage space of the storage shelf layer is obtained.

The free storage space of each shelf layer is stored in the intelligent production scheduling system, and the available storage space can be determined according to the free storage space. It is also possible to set a reserved storage space in the shelf layer to move the container with a deep front diameter, and determine the reserved storage space according to the reserved ratio (for example, 10%) and the distribution of free storage spaces on the incoming shelf layer , the storage space after the reserved storage space is removed from the available storage space, that is, the free storage space.

In some embodiments, the distribution position of the reserved storage space in the case of uniform distribution is determined according to the reserved ratio; when the distribution position has already stored the container, the free storage space closest to the distribution position is determined as the reserved storage position . For example, the reserved quantity of reserved storage spaces=reserved ratio*total quantity of storage spaces on the shelf layer, interval distance=total quantity of storage spaces on the shelf layer/reserved quantity, the distribution position of each reserved storage space can be determined. When the distribution location is already occupied, the intelligent production scheduling system automatically determines the nearest free storage location at the distribution location as the reserved storage location, and the system will automatically update it when the container at the distribution location is out of the warehouse or removed Reserved for storage.

In step S206, according to the diameter depth of the available storage space and the distance from the available storage space to the storage entrance, according to the method of preferentially selecting the available storage space with a large diameter and a short distance to the storage entrance, the available storage space is selected from the available storage space. Select an inbound storage location for the inbound container, so that the incoming container can be stored in the inbound storage location.

In some embodiments, different weights can be set for different diameters and depths of the available storage locations, and the available storage location with the smallest sum of the distance to the storage port and the corresponding weight is selected as the storage location for the container to be stored. Available storage slots with smaller diameters are given greater weight. The distance of the available storage space is the distance from the available storage space to the storage entrance in the direction of the running track of the shuttle robot. As shown in Figure 1, the distance from the front diameter depth and rear diameter depth storage position to the storage port of the same column is the same.

Further, the sum of the distance of the available storage space and the corresponding weight may be used as the storage cost of the available storage space. The weights corresponding to the available storage positions with different diameters and depths can be adjusted according to actual application or test experience. For example, take the diameter depth as the highest priority reference condition, preferably consider the diameter depth of the available storage space, that is, choose the rear diameter depth storage position first; in the case of the same diameter depth, then refer to the distance from the storage entrance to select the storage position (For example, among the available storage positions with the same diameter and depth, the one with the closest distance to the storage port is preferred). In this case, the same value can be set for the weight of the available storage space with a small diameter, and the storage cost of the available storage space with a small diameter is greater than the storage cost of any large diameter. For example, the storage cost of the front-diameter deep storage location = n+ the distance to the storage entrance, the storage cost of the rear-diameter deep storage location = the distance to the storage entrance, setting n makes the storage cost of any front-diameter deep storage location greater than The storage cost of any back-diameter deep storage location.

In the above-mentioned embodiment, the rear diameter deep storage position can be preferably selected for warehousing, and there is no need to repeatedly move the container with the front diameter deep storage position. The cargo box is also convenient for getting out of the warehouse.

Further, the increased distance of movement of the cargo box at the front diameter deep storage position can also be used as the weight of the front diameter deep storage position, and the weight of the rear diameter deep storage position is set to zero. In this case, it is mainly considered that placing the container in the deep front diameter storage position increases the distance that the corresponding deep rear diameter container needs to be moved when it leaves the warehouse. The increased distance of container movement for the deep front-diameter storage can be the sum of twice the distance from the deep front-diameter storage to the nearest reserved storage and the distance offset value, which can be the sum of lifting and The product of the sum of the time for actions such as putting down the cargo box and the average speed of the shuttle robot. For example, the storage cost of the front-diameter deep storage position = the increased distance of the container movement + the distance to the storage port, the storage cost of the rear-diameter deep storage position = the distance to the storage port, and containers with different front-diameter deep storage positions The distance increased by movement is not a fixed value.

In the above-mentioned embodiment, for the situation that there are both storage locations with short distance and small diameter depth and storage locations with long distance and large diameter depth, the storage location with short distance and small diameter depth may be selected preferentially, for example, the distance between The near front-diameter deep storage position is because even if there is a possibility of moving the container, the front-diameter deep storage position is more efficient than the rear-diameter deep storage position with a higher storage and output efficiency.

It should be noted that the implementation of the method in step S206 is not limited to determining the storage cost of each available storage location by setting weights corresponding to different diameters and adding them to the distance to the storage entrance. Multiply with the distance of the storage entrance, or directly set the selection priority, etc., as long as the same selection principle as the above-mentioned embodiment can be realized.

In the method of the above-mentioned embodiment, according to the diameter depth of the available storage space in the storage shelf layer and the distance from the available storage position to the storage entrance, the available storage space with a large diameter and a short distance to the storage entrance is preferentially selected for the storage boxes to be stored. The storage position improves the efficiency of storage in the case of multi-deep shelves.

In the present disclosure, other factors may be referred to when selecting storage locations for containers to be stored, so as to further improve storage efficiency. The following describes other embodiments of the inventory scheduling method of the present disclosure in conjunction with FIG. 3 .

Fig. 3 is a flow chart of another embodiment of the inventory scheduling method of the present disclosure. As shown in FIG. 3, the method of this embodiment includes: steps S302-S306.

In step S302, the storage aisle and the storage shelf layer in the storage aisle are determined for the container to be stored.

In step S304, the available storage space of the storage shelf layer is obtained.

In step S306, according to the distribution of the boxes on the storage shelf layer, the diameter depth of the available storage space, and the distance from the available storage space to the storage entrance, according to the front diameter depth corresponding to the box associated with the box to be stored The priority of the available storage space, the available storage space with a large diameter and a short distance to the storage entrance is reduced in descending order, and the storage space is selected for the storage box to be stored from the available storage space.

The container associated with the container to be put into storage can be determined with reference to the method in the foregoing embodiment, that is, the container with the same or associated goods stored in the container to be put into storage. Compared with the available storage space with a large diameter and a short distance to the storage port, the selection priority of the available storage space with the front diameter corresponding to the associated container is higher. That is, if there is a container associated with the container to be put into storage, and the associated container has been stored in the rear diameter deep storage position, then directly select the front diameter deep storage position corresponding to the associated container, and the Inbound containers are stored correspondingly to associated containers. If there are multiple boxes associated with the box to be put into storage, the front diameter deep storage location corresponding to the box with the highest correlation degree is selected as the storage location. If multiple boxes associated with the boxes to be put into storage have the same degree of association, then the front-diameter deep storage location corresponding to the associated box with the closest distance to the storage entrance is selected as the storage location.

In the above-mentioned embodiment, the associated containers are stored in the same row of storage positions. Since the associated containers have a high probability of being out of the warehouse at the same time or only one of them needs to be out of the warehouse to meet the outbound task, the corresponding storage It is more convenient to go out of the warehouse, and it will not bring about the problem that too many front-diameter deep storage positions need to move the container. It can also make other cargo boxes stored in the rear-diameter deep storage position that is convenient for the storage, which improves the overall delivery. Inventory and storage efficiency.

In some embodiments, the above-mentioned method for selecting a storage location for storage may be implemented in the following manner. According to the location of the associated cargo box and the diameter depth of each storage location, the available storage locations are divided into the front diameter deep storage location corresponding to the rear diameter deep storage location where the associated cargo box is located, other front diameter deep storage locations, and rear diameter depth Storage location: According to the weights corresponding to different types of available storage locations and the distance from each available storage location to the storage entrance, select the storage location for the container to be stored from the available storage locations.

Further, the weights corresponding to the front-diameter deep storage positions, rear-diameter deep storage positions, and other front-diameter deep storage positions corresponding to the rear-diameter deep storage positions where the associated cargo boxes are located are sequentially reduced; the distance to the storage port and the corresponding weight The available storage space with the smallest sum is selected as the storage space for the container to be stored.

In the above-mentioned embodiment, the front-diameter deep storage position corresponding to the rear-diameter deep storage position where the associated container is located is preferentially selected. Further, the selection method of other front-diameter deep storage positions and rear-diameter deep storage positions can refer to the previous embodiments according to the diameter. The method of selecting the storage location based on the depth and the distance from the storage entrance.

The embodiments in Fig. 2 and Fig. 3 can be applied in combination with each other further according to the ratio of available storage positions. In some embodiments, when the ratio of the available storage slots to the total storage slots in the incoming shelf layer is lower than the preset value, according to the distribution of goods on the incoming shelf layer, the diameter and depth of the available storage slots, and the available The distance from the storage location to the storage entrance, select the storage location for the storage box from the available storage location; when the ratio of the available storage location to the total storage location in the storage shelf layer exceeds the preset value , according to the diameter and depth of the available storage space and the distance from the available storage space to the storage port, select the storage space for the container to be stored from the available storage space.

When the ratio of the available storage space to the total storage space is lower than the preset value, the filling rate of the shelf layer is already high, and the corresponding storage of the associated container can be prioritized. Further reference is made to the diameter and depth of the storage space. Select the storage location for the distance from the storage entrance. When the ratio of the available storage spaces to the total number of storage spaces exceeds the preset value, the filling rate of the shelf layer is low, and there are more available storage spaces. The distance to select the storage location.

In the method of the above-mentioned embodiment, according to the proportion of the available storage space, different determination methods are adopted for the warehouse-in storage space. When the proportion of the available storage space is low, the corresponding storage of the associated container is given priority, and when the proportion of the available storage space is high Under the circumstances, the storage location is selected according to the diameter depth and the distance to the storage entrance, adapting to different storage scenarios, comprehensively considering various factors, and improving the efficiency of storage and delivery as a whole.
