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 method for adjusting storage locations of shelves, which is applied to a warehouse management system, where a plurality of shelves and a plurality of storage locations of shelves are configured, 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, and sorting the plurality of shelf storage positions according to the sorting coefficients, wherein the sorting coefficients are smaller and the sorting of the corresponding shelf storage positions is earlier;

s103, generating an adjustment task to adjust the goods shelf to be adjusted away.
Illustratively, the ranking value of the shelves, storage locations is calculated first.
Wherein, the goods shelves are ordered: all commodities on the shelf are taken, the click rate of the commodities is averaged, namely the click rate of the shelf is sorted according to the click rate. And (5) sequencing storage bits: and weighting the workstations according to the ex-warehouse rate of the historical workstations, and then obtaining the distances from the storage locations to the workstations, and sequencing the distance cost. It is the fact that the more frequent the work station is out of stock, the highest rank of the storage around the work station, and the lowest rank of the storage further from the work station.
The average click rate of the assigned shelves of the adjustment tasks is ranked and calculated to be the total proportion (ranking/total number) and R is used 0 And (3) representing.
Setting an initial proportion P 0 (e.g., 20%), increase P a (e.g., 10%), find storage ranks at P 0 Goods shelves on storage locations in, if R of the goods shelves 0 Ratio P 0 And (3) large, selecting the goods shelf A with the rearmost ranking.
Without making P 0 ＝P 0 +P a Re-executing the above steps until P 0 Stop =1.
And directly generating a shelf adjustment task according to the selected shelf A, wherein the state is newly built.
In the embodiment, the goods shelves with lower heat values in the goods shelf storage positions with the front ranks are adjusted away, so that the goods shelves with the front ranks can be idle to receive the storage goods shelves, and the storage returning efficiency of the goods shelves is improved. In addition, the shelf storage position with the front arranged position can be used for accommodating other shelves with higher heat in a warehouse, so that the shelves with higher heat can be used for effectively carrying out warehouse delivery, and the carrying distance of warehouse delivery is reduced due to the front arranged position of the shelf with the higher heat, and the quantity and energy consumption of required carrying vehicles are reduced.
In some embodiments, a preset condition is required to be met before the shelf storage adjustment method is performed, the preset condition including:
the interval between the current time point and the next wave starting time is larger than a set time threshold; and/or
The idle rate of the plurality of vehicles for carrying the racks is lower than the set idle rate; and/or
The average electrical quantity of the plurality of vehicles for transporting the racks is greater than the set electrical quantity threshold.
The implementation is limited by preset conditions, so that the adjustment of the storage position of the goods shelf can not influence the normal warehouse operation.
In this embodiment, the automatic adjustment procedure 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 time point of the wave (each warehouse will be configured with all wave times).
As shown in fig. 2, according to the wave number table and the length of the adjacent time.
Wherein the JIT cut time is all customer orders received before this time; JIT end time refers to the time before orders prior to JIT cut must all be closed again before they are produced out of stock; the JIT start time refers to the order at which production of this wave is restarted at the start time.
Illustratively, the set time threshold may be 10 minutes. Near the time point of the wave frequency, taking the wave frequency pressure and preventing sudden batch ordering into consideration, the shelf adjustment is not performed, and the delivery efficiency is ensured.
2. Idle rate of trolley
Record the total number of carts per minute
Number q of idle carts is And calculating the idle rate of the trolley for five continuous minutes:
wherein alpha is 1 Configurable to 0.5, no five minute idle rate exceeds alpha 1 An automatic adjustment task may be triggered.
3. Average electric quantity of all trolleys.
Monitoring the electric quantity conditions of all trolleys: total car charge/total car charge = average car charge d.
d>α 2
Wherein alpha is 2 It can be configured as 50, if the average electricity quantity is higher than 50, the electricity quantity is generally in a normal range, and if the average electricity quantity is lower than 50, the electricity quantity is lower than the whole day and needs to be charged, and the shelf adjustment task is not regenerated.
4. While only one adjustment task is allowed to do.
The automatic task needs to be controlled to generate one at a time, and a new one is generated after the task is finished.
The scheduling system calls a BPC (order center for receiving order information of the peripheral system and managing a task life cycle generated inside the system) system to inquire whether an unfinished adjustment task exists currently, and if not, a new task is generated.
In some embodiments, shelves in the warehouse begin from respective shelf locations to respective workstations to complete the delivery of the items on the shelves;
the determining a plurality of ranking coefficients corresponding to the plurality of shelf locations based at least on a plurality of range distances from the plurality of shelf locations, and ranking the plurality of shelf locations based on the ranking coefficients comprises:
Respectively determining a plurality of distance from the storage positions of the plurality of shelves to the corresponding workbench;
determining corresponding workbench weights according to the ex-warehouse frequencies of the corresponding workbench respectively;
determining a plurality of ranking coefficients corresponding to the plurality of shelf locations according to the plurality of range distances and the corresponding table weights; illustratively, multiplying each of the plurality of range distances by a corresponding respective table weight to obtain a plurality of ranking coefficients corresponding to the plurality of shelf locations;
and sequencing the plurality of shelf storage positions according to the sequence from small to large of the plurality of sequencing coefficients.
In the embodiment, the sorting coefficient of the storage positions of the goods shelves is determined through two factors of the distance and the delivery frequency of the workbench, so that reasonable sorting of the storage positions of the goods shelves is realized. The high frequency of the delivery rate of the workbench indicates that the workbench is high in working efficiency, so that the workbench can bear delivery of more shelves, and therefore the sequencing coefficient is determined based on two factors of the distance of the journey and the delivery rate of the workbench, sequencing of storage positions of the shelves is achieved, and reasonable configuration of resources is achieved. Further, the situation that the same storage position of the goods shelf is the same distance from two different work tables can be solved.
In some embodiments, the determining a plurality of heat values of the plurality of shelves on the plurality of shelves storage locations ordered in front and determining a shelf corresponding to a minimum value of the plurality of heat values as the shelf to be adjusted includes:
determining a plurality of shelves on a top plurality of shelf locations;
performing, for each of the determined plurality of shelves: determining the average clicking times of the goods on the goods shelf as the heat value of the goods shelf;
and determining the shelf corresponding to the minimum value in the determined heat values 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) of the plurality of heat values does not necessarily represent a low heat level (absolute heat level) of the shelf to which the minimum value corresponds, because it is possible that the plurality of heat values are all relatively large, for example, heat values 100, 99, 98, and although 98 of the three heat values is the smallest (relative heat level is the smallest), 98 itself is actually large (absolute heat level is actually large). In this embodiment, by limiting the minimum value to be smaller than the preset heat value, it is possible to avoid determining the shelf with a larger absolute heat value as the shelf to be adjusted, and unnecessary shelf transportation and resource consumption caused thereby are avoided.
In some embodiments, the generating an adjustment task to adjust the rack to be adjusted away includes:
determining a target storage position for receiving the goods shelf to be adjusted, and preferentially selecting the goods shelf storage position in the empty state as the target storage position;
when the target storage position is in an empty state, generating an adjustment task for carrying the goods shelf to be adjusted to the target storage position;
and when the target storage position is in an occupied state, generating an adjustment task for carrying the goods shelves to be adjusted and the goods shelves occupying the target storage position in an exchange manner.
In this embodiment, the scheduling calculates the adjustment scheme, that is, 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 with, and finally the adjustment task (that is, the adjustment pair of the shelf a and the shelf B or the adjustment pair of the shelf a and the storage location L) is obtained.
In this embodiment, the storage position of the shelf in the empty state is preferentially selected as the target storage position, so that the number of transport vehicles needing to be mobilized can be reduced as much as possible during adjustment, on one hand, the resources and energy sources of the transport vehicles can be saved, and on the other hand, the adjustment efficiency is improved.
In some embodiments, the determining a destination storage location for receiving the rack to be adjusted comprises: searching storage positions of the empty state shelf:
Determining a ratio between the sorting value of the shelves to be adjusted and the total number of the plurality of shelves participating in sorting as a first ratio;
searching for empty state shelf storage positions in the sorting of the plurality of shelf storage positions according to the first ratio;
and (3) searching storage positions of the occupied state shelf:
when the control state shelf storage position is not found, determining a plurality of heat values of a plurality of shelves arranged on the plurality of shelf storage positions;
and determining the shelf storage position corresponding to the maximum value in the heat values of the plurality of shelves arranged on the plurality of shelf storage positions at the back as the occupied state shelf storage position.
Illustratively, for the empty state shelf storage location lookup step, the following closest empty storage location selection algorithm may be employed:
1. setting acceptable shelf search range P s (e.g., 10%);
2. designated shelf average point to adjust tasksThe click rate ranking is converted into the total proportion (ranking/total) and R is used 0 And (3) representing.
3. In the order of section [ max (0, R) 0 -P s )，min(1，R 0 +P s )]The empty bins ranked closest to the average click rate of the selected shelf are found among the bins within.
4. And if the empty storage position exists, generating an adjustment task for designating the goods shelf to the empty storage position.
5. If not, returning to the empty storage position.
For the occupancy state shelf location lookup step, the following backward swap shelf selection algorithm may be employed:
1. setting an initial proportion P 0 (e.g., 20%) acceptable ratio range P r (e.g., 10%) increase P a (e.g., 10%);
2. examine in-library ordering at P 0 +P r Shelves on outer bins, if there is an average click-through ordering from small to large on P 0 And selecting the shelf with the highest ranking.
3. Checking the state of the selected shelf, and if the state is not already on the shelf, not selecting the shelf as the opposite shelf. If not already on the shelf, it is stated that no adjustment task can be done on the road or in other tasks. For the shelf state, there are tables that are dedicated to constantly maintaining various states of the shelf.
4. Dijkstra path costs for a selected shelf and a designated shelf are checked, and if the path costs are not good or are below a set threshold (e.g., 100, below a certain value, indicating that physical locations are close together and no change is necessary), then the shelf is not selected as the opposite shelf.
As shown in fig. 3, which is a flowchart of an embodiment of a shelf storage adjustment method of the present application, the related subject matter includes: scheduling module, console, workstation and operation platform/BPC. The scheduling module, namely intelligent scheduling, is an algorithm module for example, calculates optimal selection or combination of various tasks and generates corresponding carrying tasks; the control console is illustratively a trolley management module and is responsible for processing feedback and issuing of trolley carrying tasks; work stations, illustratively, work areas for ex-warehouse picking, are divided into manual picking stations and automatic picking stations; an operator platform/BPC, illustratively an order center, is used to receive order information for the peripheral systems, and to manage internally generated task lifecycles for the systems.
The method for adjusting the storage position of the goods shelf shown in fig. 3 comprises the following steps:
a. the scheduling module starts to execute the timing task and judges whether the automatic generation condition is met;
b. if yes, the production scheduling module calculates a goods shelf to be adjusted, otherwise, the process is finished;

FIG. 4 is a flow chart of one embodiment of performing tasks in the shelf storage adjustment method of the present application.
And the control console receives the transport task, if the transport task is a transport task, the control console is similar to the common transport task, and the goods taking rack is sent to the target storage position.
If the two handling tasks are two, consistency needs to be ensured, and the handling is successfully executed;
if the abnormal condition of a certain car can not take the journey at the same time, the car is manually processed or the car is replaced, and then the recovery task is continued to finish the carrying task.
In some embodiments, the adjustment task is completed when one or both of the handling tasks under the task are successful.
The embodiment of the application also comprises the steps of managing the life cycle state of the adjustment task:
the row is generated into a task, and the task state is newly built;
the row generates a carrying task, and the task state is updated to be in work;
after the console is carried out, the task state is changed to be finished;
when the transport tasks are calculated in scheduling mode, no proper destination storage position exists, the workstation is called to inform the task cancellation, and the task state is updated to cancelled.
