Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
As shown in fig. 1, an embodiment of the present application provides a shelf storage position adjusting method, which is applied to a warehouse management system, where a plurality of shelves and a plurality of shelf storage positions are configured in the warehouse, and the method includes:
s101, determining a plurality of sorting coefficients corresponding to the plurality of shelf storage positions at least according to a plurality of distance distances from the plurality of shelf storage positions to be taken out of a warehouse, and sorting the plurality of shelf storage positions according to the sorting coefficients, wherein the smaller the sorting coefficient is, the higher the corresponding shelf storage position is;

and S103, generating an adjusting task and adjusting away the shelf to be adjusted.
Illustratively, the ranking values of the shelves and the storage positions are calculated firstly.
Wherein, the shelf ordering: the click rate of all the commodities on the goods taking rack is averaged, namely the click rate of the goods shelf is sorted according to the click rate. Storage position sorting: and weighting the workstations according to the ex-warehouse rate of the historical workstations, and then obtaining the distance between the storage position and the workstations, and sorting the distance cost. In fact, the storage positions around the workstations with more frequent warehouse-out are ranked the highest, and the storage positions farther away from the workstations are ranked the lowest.
The specified shelf average click rate of the adjustment task is converted into a total proportion (sorting/total) and R is used0And (4) showing.
Setting an initial ratio P0(e.g. 20%) increase Pa(e.g., 10%) the search bin is ordered at P0Shelf in the inner storage position, if R of shelf0Ratio P0Large, select shelf a ranked the most backward.
If not, order P0＝P0+PaRe-executing the above steps until P0Stop 1.
And directly generating a shelf adjusting task according to the selected shelf A, wherein the state is new.
The lower goods shelves of the heat value in the goods shelves storage position that the rank is close to in this embodiment are transferred away to can make the goods shelves storage position that the rank is close to idle down to receive back the storehouse goods shelves, improve the efficiency of getting back the storehouse of goods shelves. In addition, the shelf storage position which is close to the front of the given-out rank can be used for accommodating other shelves with higher heat in the warehouse, so that the shelves with higher heat can be more efficiently taken out of the warehouse, and the storage position which is located at present is close to the front, so that the carrying distance of the shelves which are taken out of the warehouse is reduced, and the number of required carrying vehicles and the energy consumption are reduced.
In some embodiments, a predetermined condition is satisfied before the shelf slot adjustment method is performed, the predetermined condition including:
the interval between the current time point and the next wave starting time is greater than a set time threshold; and/or
The vacancy rate of a plurality of vehicles for carrying the goods shelf is lower than the set vacancy rate; and/or
The average electric quantity of a plurality of vehicles for carrying the goods shelf is larger than the set electric quantity threshold value.
This implementation is through the restriction of presetting the condition for can not influence normal warehouse operation to the adjustment of goods shelves storage position.
In this embodiment, the automatic adjustment process is considered to reduce the pressure on the normal operation, and is automatically created when at least one of the following rules is satisfied:
1. not currently near the point in time of the wave (every warehouse will be configured with all the wave times).
As shown in fig. 2, configured according to the wave-schedule and the proximity time length.
Wherein the JIT order taking time is all customer orders received before this time; JIT end time refers to production ex-warehouse before all orders before JIT take an order must end time again; JIT start time refers to the time at which the order for this wave is to be produced.
Illustratively, the set time threshold may be 10 minutes. Near the wave time point, the wave pressure is considered, the sudden batch ordering is prevented, the goods shelf adjustment is not made, and the ex-warehouse efficiency is ensured.
2. Vehicle idle rate
Recording total number of trolleys per minute
Number q of idle trolleysisAnd calculating the idle rate of the trolley for five continuous minutes:
wherein alpha is1Configurable 0.5, no five minute idle rate exceeds a1An auto-adjustment task may be triggered.
3. Average electric quantity of all the trolleys.
Monitoring the electric quantity conditions of all trolleys: and the sum of all trolley electric quantity/the total trolley number is the average trolley electric quantity d.
d>α2
Wherein alpha is2The configuration can be 50, and the average power is higher than 50, which indicates that the power is generally in a normal range, and the average power is lower than 50, which indicates that the power is lower throughout the day and needs to be charged, so that the shelf adjustment task can not be generated.
4. While only one adjustment task is allowed to be done.
The method avoids occupying too many vehicles, the automatic tasks need to be controlled to be generated one at a time, and a new one is generated after the tasks are finished.
The scheduling system calls a BPC (order center) system to inquire whether an unfinished adjusting task exists currently or not, and if not, a new task is generated.
In some embodiments, the shelves in the warehouse are moved from the corresponding shelf storage positions to the corresponding working platforms to complete the delivery of the goods on the shelves;
the determining a plurality of ranking coefficients corresponding to the plurality of shelf locations based at least on the plurality of distance traveled out of the plurality of shelf locations and ranking the plurality of shelf locations based on the ranking coefficients comprises:
respectively determining a plurality of distance distances from the plurality of shelf storage positions to the corresponding workbench;
determining corresponding workbench weights according to the ex-warehouse frequency of the corresponding workbench respectively;
determining a plurality of ranking coefficients corresponding to the plurality of shelf reservoirs based on the plurality of range distances and the respective table weights; illustratively, each of the plurality of trip distances is multiplied by the corresponding respective table weight to obtain a plurality of ranking coefficients corresponding to the plurality of shelf slots, respectively;
and correspondingly sequencing the shelf storage positions according to the sequence of the sequencing coefficients from small to large.
In the embodiment, the sorting coefficient of the storage positions of the goods shelves is determined by two factors, namely the distance and the ex-warehouse frequency of the workbench, so that the reasonable sorting of the storage positions of the goods shelves is realized. The high ex-warehouse rate frequency of the workbench indicates that the workbench is high in working efficiency, so that the workbench can bear more ex-warehouse shelves, and the sorting coefficient determined by the embodiment of the application based on two factors, namely the distance and the ex-warehouse frequency of the workbench, not only realizes sorting of storage positions of the shelves, but also realizes reasonable allocation of resources. Furthermore, the problem that the distance between the same storage position of the shelf and two different working tables is the same can be solved.
In some embodiments, the determining a plurality of heat value of a plurality of shelves on the top-ranked shelf storage locations, and determining the shelf corresponding to the minimum value of the plurality of heat value as the shelf to be adjusted includes:
determining a plurality of shelves on a top plurality of shelf bays;
performing, for each shelf of the determined plurality of shelves: determining the average click times of the commodities on the shelf as the heat value of the shelf;
and determining the shelf corresponding to the minimum value in the plurality of determined heat value as the shelf to be adjusted.
In some embodiments, the minimum value should also be less than a preset heat value. The minimum value (relative value) among the plurality of heat values does not necessarily represent that the rack corresponding to the minimum value has a low heat value (absolute heat value) because there is a possibility that the plurality of heat values are all relatively large, for example, the heat values 100, 99, and 98 are all large, and although 98 is the smallest among the three heat values (relative heat value is smallest), 98 itself is actually large (absolute heat value is actually large). In this embodiment, by limiting the minimum value to be smaller than the preset heat value, the shelf with the larger absolute heat value can be prevented from being determined as the shelf to be adjusted, and unnecessary carrying of the shelf and resource consumption caused thereby are avoided.
In some embodiments, the generating an adjustment task to tune away the shelf to be adjusted comprises:
determining a target storage position for receiving the shelf to be adjusted, and preferentially selecting the shelf storage position in an empty state as the target storage position;
when the target storage position is in an empty state, generating an adjusting task for transporting the goods shelf to be adjusted to the target storage position;
and when the target storage position is in an occupied state, generating an adjusting task for exchanging and carrying the shelf to be adjusted and the shelf occupying the target storage position.
In this embodiment, the scheduling calculation adjustment scheme is that which storage location the selected shelf should go to, and if there is a shelf on the storage location, which shelf needs to be adjusted, and finally an adjustment task is obtained (i.e., adjustment of the shelf a and the shelf B or adjustment of the shelf a and the storage location L).
In this embodiment, the empty storage rack is preferentially selected as the target storage rack, so that the number of transport vehicles to be moved can be reduced as much as possible when the adjustment is performed, on one hand, the resources and energy of the transport vehicles can be saved, and on the other hand, the adjustment efficiency is improved.
In some embodiments, the determining a destination bay for receiving the shelf to be adjusted comprises: the method comprises the steps of empty state shelf storage position searching:
determining that the ratio of the sorting value of the shelf to be adjusted to the total number of the plurality of shelves participating in sorting is a first ratio;
searching empty shelf storage positions in the sequencing of the plurality of shelf storage positions according to the first ratio;
and (3) searching storage positions of occupied state shelves:
when the control state shelf storage position is not found, determining a plurality of heat values of a plurality of shelves on a plurality of shelf storage positions which are sequenced;
and determining the shelf storage position corresponding to the maximum value in the plurality of heat values of the plurality of shelves on the plurality of shelf storage positions which are sequenced in the past as the occupied state shelf storage position.
For example, for the empty state shelf storage location searching step, the following nearest empty storage location selection algorithm may be employed:
1. setting an acceptable shelf search range Ps(e.g., 10%);
2. the specified shelf average click rate of the adjustment task is converted into a total proportion (sorting/total) and R is used0And (4) showing.
3. In the sequence in the interval [ max (0, R)0-Ps)，min(1，R0+Ps)]The empty bin with the rank closest to the selected shelf average click rate rank is found in the bins in the inner.
4. And if the storage position is available, generating an adjustment task from the designated shelf to the empty storage position.
5. If not, returning no empty storage bit.
For example, for the occupancy shelf bin search step, the following backward swap shelf selection algorithm may be employed:
1. setting an initial ratio P0(e.g., 20%) acceptable ratio range Pr(e.g. 10%) increase Pa(e.g., 10%);
2. rank in P in the survey library0+PrThe goods shelves on the outer storage positions are sorted in P from small to large if the average click quantity is sorted0And selecting the shelf with the top rank from the shelves in the interior.
3. And checking the state of the selected shelf, and if the state is not the shelf-on-shelf state, not selecting the shelf as the opposite shelf. If the adjustment task is not on the shelf, the adjustment task cannot be performed on the road or other tasks. For the shelf state, a table is used for continuously maintaining various states of the shelf.
4. Dijkstra path costs for the selected shelf and the designated shelf are verified, and if the path costs are not good or are below a set threshold (e.g., 100, below a certain value, indicating that the physical locations are close together and not necessary for replacement), the shelf is not selected as the counter shelf.
As shown in fig. 3, which is a flowchart of an embodiment of the shelf storage position adjustment method of the present application, the related subject matter includes: scheduling module, console, workstation and operation platform/BPC. The scheduling module, namely an intelligent scheduling module, exemplarily serves as an algorithm module, calculates the optimal selection or combination of various tasks, and generates corresponding carrying tasks; the console, illustratively a trolley management module, is responsible for processing the feedback and issuing of the trolley carrying task; the working stations are divided into a manual picking working station and an automatic picking working station; the operations platform/BPC, illustratively an order center, is used to receive order information for peripheral systems and to manage task life cycles generated within the system.

b. if so, the scheduling module calculates the shelf needing to be adjusted, otherwise, the operation is finished;
c. the operation platform/BPC establishes a shelf adjustment task (the state is newly added);
d. the workstation receives the task (activation);
e. the scheduling module calculates a destination storage position to generate a carrying task;
f. the console, the workstation and the operation platform/BPC coordinate to complete the adjustment task and the transportation task.
Fig. 4 is a flowchart illustrating an embodiment of a task executed in the shelf storage position adjustment method according to the present application.
The console receives the carrying task, if the carrying task is similar to a common carrying task, the goods taking frame is sent to the target storage position.
If the two carrying tasks are carried out, consistency needs to be ensured, and carrying is carried out after the carrying tasks are successfully carried out;
if a certain vehicle is abnormal and cannot take a journey at the same time, the manual handling of the vehicle is finished or the vehicle changing is executed, and then the task is recovered to continue to finish the carrying task.
In some embodiments, the task completion is adjusted when one or both of the transfer tasks under the task are successful.
The embodiment of the application also comprises the following steps of managing the life cycle state of the adjustment task:
scheduling to generate a task, wherein the task is in a new state;
scheduling to generate a carrying task, and updating the task state into working;
after the console finishes transporting, the task state is changed into finished;
when the scheduling calculation and carrying tasks do not have proper target storage positions, the work station is called to inform the task cancellation, and the task state is updated to be cancelled.
