Detailed Description
Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings, in which various details of the embodiments of the present invention are included to facilitate understanding, and are to be considered merely exemplary. 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.
In the process of warehouse-out order processing of a warehouse-in-warehouse, an order with a shortage (the order with the shortage refers to an article with the shortage in the order) is likely to appear in the picking stage, the secondary sorting stage and the rechecking and packaging stage, and the order with the shortage is separated from the processing flow of a normal order in the prior art by adopting the following modes: one is to generate the order of the shortage alone and select the work order, carry out the order of this order separately, this kind of processing the processing efficiency of order mode of the shortage is lower; the other is that when the order is in shortage, a rollback repositioning mode is adopted to pick the order, so that the processing efficiency is low; and the other is to aggregate or accumulate the shortage orders to a certain number (such as 20-30 sheets) and then centralize the batch to complete the picking of the shortage articles. Therefore, the processing flow of the prior art on the shortage order is separated from the picking flow which is being executed, so that the processing efficiency on the shortage order is low and the processing time is long. Therefore, it is desirable to provide an order processing method that combines efficiency and aging.
FIG. 1 is a schematic diagram of the main flow of an order processing method according to an embodiment of the present invention, as shown in FIG. 1, the order processing method includes:
Step S101: in response to receiving an ullage request for an order, determining a supplemental pick location and preempting available inventory for the order according to an item identification of items absent from the order indicated by the ullage request;
in the embodiment of the invention, the order may be a pick-up order or one or more orders in the pick-up order, where the pick-up order includes an order number corresponding to the one or more orders, an item identifier of an item to be picked and a corresponding item number included in each order. The picking task can be generated according to the picking work order, and the picking task can be a combination of identification of the objects to be picked, the number of the objects to be picked, position information (namely, the position of a warehouse) of the objects to be picked and the like which are issued to a terminal by a server in the form of a bill or the picking work order, and the picking task is executed by a picker to finish picking of the objects to be picked. The picker is not particularly limited and may be a person or intelligent picking device. The order details are shown in Table 1 as a pick sheet comprising 6 orders (order numbers WO1, WO2, WO3, WO4, WO5 and WO6, respectively) with each order specifying the item that is scheduled to be taken and the corresponding number of scheduled to be taken (i.e., the number to be picked), such as order WO1 scheduled to pick 2 SKUs 1, order WO2 scheduled to pick 2 SKUs 1 and 1 SKU3, where SKU1, SKU2, SKU3 and SKU4 are item identifications for different items.
TABLE 1
In the embodiment of the invention, the bin can be the position of the article in the channel in which the warehouse is located, the warehouse comprises a plurality of channels, each channel comprises a plurality of bins, the articles with different article identifications can be stored in one bin or a plurality of bins, and the articles with the same article identifications can also be stored in one or a plurality of bins.
The information of each library bit comprises the identification of the library bit, the identification of the stored article in the library bit and the stock quantity of the stored article, and each library bit corresponds to an identification code, such as a bar code or a two-dimensional code, through which the information of the library bit can be obtained. The identification of the bin corresponds to the position of the bin, and the identification of the bin may be a picking path sequence number, for example, a picking path in which the picking path sequence numbers of the bins of the whole warehouse are all included is a maximum picking path, an initialized picking path of each picking task is a maximum picking path, and the picking task is executed according to the picking path sequence number.
In the embodiment of the invention, the missing items are missing items indicated in the missing amount request of the order, namely, the missing items in the missing amount order, the complementary picking positions are positions where the stock positions capable of supplementing the number of the missing items are located, the available stock is the available stock for the missing items in the picking positions, namely, the item identification and the item number of the missing items in the picking positions are pre-occupied according to the number of the missing items in the missing amount request and the stock quantity of the missing items in the picking positions, so that the missing items can be picked in the picking positions later. I.e., picking location refers to the location of one or more bins at which items missing from the order are located; preempting available inventory is indicating items missing from an order, pre-empting inventory at one or more inventory levels such that the pre-occupied inventory is no longer occupied by other orders.
In embodiments of the present invention, the shortage of orders may occur at any one of the pick-up stage, the secondary sort stage, and the review package stage. When the items in the order form are in the shortage, a shortage request is generated, the shortage request indicates the item identification of the items which are in shortage in the order form, and also indicates the quantity of the items which are in shortage, and the shortage request can be a request sent to a server by a terminal device. The terminal device may be an RF scanning terminal, and during picking, the RF scanning terminal may obtain and/or update information about a bin by scanning an identification code of the bin, e.g., after picking an item in a bin, update an inventory of the item in the bin.
In an embodiment of the present invention, in step S101, one implementation of determining a supplemental pick location for the order includes:
locating one or more bins with item identifications and providing information of the one or more bins;
in response to receiving a selection of information for one or more target library bits, a determination is made that the location of the one or more target library bits is a supplemental selected location.
One or more bins with item identifications of items missing in the order are located based on the item identifications of items missing as indicated by the demand request, and the inventory level of item identifications of items missing in the one or more bins can be known. When the stock quantity of one stock position is larger than the quantity of the articles lacking in the shortage request, selecting the stock position as a target stock position, and taking the position of the target stock position as a supplementary picking position; when the stock quantity of the missing items in the plurality of stock positions is larger than the quantity of the missing items in the missing quantity request, one of the plurality of stock positions can be randomly selected as a target stock position, and the position of the target stock position is used as a supplementary picking position, so that the missing items of the missing quantity order can be picked at the picking position.
When the stock quantity of any one of the one or more stock positions with the missing item identification is smaller than the quantity of the missing items in the missing quantity request, selecting at least two stock positions with the sum of the stock quantity being larger than the quantity of the missing items as target stock positions, and taking the positions of the at least two target stock positions as supplementary picking positions so as to pick the missing items in the order at the picking positions; when the sum of the stock quantity of one or more stock positions with the missing item identification is smaller than the quantity of the missing items, the stock positions can be used as target stock positions, the positions of the target stock positions are determined to be complementary picking positions, the missing items are picked from the picking positions, the picking flow of the remaining missing items can be directly transferred to the next stage, and if the picking cannot be completed in the picking stage, the flow can be transferred to the secondary sorting stage or the rechecking packaging stage for processing.
When one or more stock positions are selected as target stock positions, the articles corresponding to the article identifications of the absent articles in the target stock positions are subjected to available stock preemption, namely the stock quantity of the available stock preemption is locked, so that the available stock available for preemption of the target stock positions is reduced, and after the articles in the target stock positions, which are subjected to available stock preemption, are selected, the stock quantity of the target stock positions is updated.
In an embodiment of the present invention, as shown in FIG. 2, in step S101, another implementation of determining supplemental pick locations for the order includes the steps of:
step S201: locating one or more bins having the item identification;
step S202: selecting at least one target bin from one or more bins according to the quantity of the items missing from the order and the inventory quantity of the items missing from the order, which are further indicated by the demand request;
step S203: and determining that the position of one or more target stock positions is the supplementary picking position.
In the embodiment of the invention, one or more stock positions with article identifications are positioned, at least one target stock position is selected according to the article identifications of the missing articles indicated by the shortage request, the number of the missing articles and the stock quantity of the one or more stock positions, specifically, if the stock quantity of the missing articles in one stock position is larger than the number of the missing articles in the shortage request, the stock position is selected as the target stock position, and the position of the target stock position is determined to be a supplementary picking position; if the stock quantity of the articles lacking in the plurality of stock positions is larger than the quantity of the articles lacking in the shortage request, one of the plurality of stock positions can be randomly selected as a target stock position, the position of the target stock position is used as a supplementary picking position, and the position of the target stock position can be selected as the supplementary picking position nearby according to the identification of the stock position.
In another embodiment, one or more stock locations with item identifications are located, when the stock quantity of items missing in any one of the one or more stock locations is less than the quantity of items missing in the shortage request, at least two stock locations with a sum of stock quantity greater than the quantity of items missing in the shortage request can be selected as target stock locations, and the positions of the at least two target stock locations are determined to be complementary picking positions; if the sum of the stock amounts of the missing items in all the stock positions is smaller than the number of the missing items in the missing request, the plurality of stock positions can be used as target stock positions, the positions of the target stock positions are determined to be complementary picking positions, the missing items are picked from the picking positions, the picking flow of the remaining missing items is transferred to the next stage, and the missing order flow can also be directly transferred to the next stage, for example, the picking stage can not be completed, and then the picking flow is transferred to the secondary sorting stage or the rechecking packaging stage for processing.
In the embodiment of the invention, the position of the target bin is positioned on the picking path after the position of the current picking bin, so that the distance of the picked item can be reduced, and the picking efficiency is improved.
The method has the advantages that the supplementary picking position is determined for the order according to the demand of the shortage of the order, and the available inventory is preempted, so that the shortage order is added or embedded into the picking task which is being executed or is about to be executed later, the picking of the articles which are lacking in the shortage order is completed, the processing efficiency of the shortage order is improved, the processing time is shortened, and the shortage order is not independently generated into the picking work order for processing, so that the processing efficiency is low.
Step S102: adding the location of the supplemental pick and the pre-empted available inventory to a pick order being performed or to be performed;
in an embodiment of the present invention, an implementation manner of step S102 includes: for the case where the order is in the pick stage, the pick location and the pre-emptive available inventory are added to the pick task currently being performed in which the order is located.
When the order is in the picking stage, a picker picks the to-be-picked object according to the original picking task of the order, when the stock quantity of the stock position of the to-be-picked object in the original picking task is insufficient, an shortage request is generated, the to-be-picked object is the object lacking in the order, the supplementary picking position and the pre-occupied available stock are determined according to the object identification and the object quantity of the lacking object indicated by the shortage request, and if the picking position is located behind the position of the stock position of the to-be-picked object in the original picking task, the supplementary picking position and the pre-occupied available stock are added into the original picking task. If the picking position is located before the position of the warehouse of the object to be picked in the original picking task, the picking position and the pre-occupied available inventory are added to the other picking tasks
In an embodiment of the present invention, another implementation manner of step S102 includes: for the case where the order is in the sort stage or review stage,
searching a first target picking task with a corresponding bin position of the picking position in the picking tasks which are being executed or are to be executed;
if found, the picking location and the pre-empted available inventory are added to the first targeted picking order.
In a sorting stage or a compounding stage, when an order has an article with an unfilled quantity, an unfilled quantity request is generated, a supplementary picking position and an available inventory are determined according to the identification of the article with the unfilled quantity indicated by the unfilled quantity request, whether a bin corresponding to the picking position exists in a picking task which is being executed or is to be executed is searched, if the bin corresponding to the picking position exists in the picking task, namely, the article with the unfilled quantity and the inventory quantity of the article with the unfilled quantity are stored in the bin to be picked of the picking task, the picking task is used as a first target picking task, the picking position and the available inventory with the unfilled quantity are added into the first target picking task, so that the first target picking task executes the picking of the article with the unfilled quantity, the subsequent pairing with the order is facilitated, and the processing of the order with the unfilled quantity is completed.
According to the picking path of the picking task, setting a picking sequence for the bin through which the picking path passes; if the first target picking task cannot be found, judging whether the picking position corresponding to the bin is located behind the current picking bin of the picking task according to the picking sequence of the picking tasks, and if so, adding the picking position and the pre-occupied available inventory to the picking task. That is, if there is no bin corresponding to the picking position in the picking task being performed or to be performed, that is, the picking position is a non-to-be-picked bin of the picking task being performed or to be performed, it is determined whether the bin corresponding to the picking position is located after the current picking bin of the picking task being performed, if so, the picking position and the pre-occupied available inventory are added to the picking task, and if not, the picking position and the pre-occupied available inventory are added to the picking task to be performed.
In the embodiment of the invention, when the bin corresponding to the picking position is positioned behind the current picking bin of a plurality of picking tasks,
for each picking path, calculating the distance between each to-be-picked bin remaining in the picking path and the bin corresponding to the picking position;
Determining a second target picking task of the to-be-picked bin with the smallest bin distance corresponding to the picking position;
the pick location and the pre-empted available inventory are added to the second target pick order.
In the embodiment of the invention, each picking task corresponds to an initialized picking path, the positions of the to-be-picked bins in the picking tasks are traversed according to a certain sequence to pick the objects in the picking tasks, when the sequence numbers of the bins corresponding to the picking positions are located behind the sequence numbers of the current picking bins of the plurality of picking tasks, the difference value between the sequence numbers of each remaining to-be-picked bin and the sequence numbers of the bins corresponding to the picking positions is calculated, the picking task with the smallest difference value of the to-be-picked bins is taken as a second target picking task, and then the picking positions and the pre-occupied available inventory are added to the second target picking task, so that the second target picking task picks the missing objects, and the picking of the objects missing in the missing objects of the missing quantity order is completed rapidly.
In the embodiment of the invention, after a bin corresponding to a picking position is located at a current picking bin of a plurality of picking tasks, calculating a distance between a next bin to be picked of each picking task and a bin corresponding to the picking position for each picking path, namely calculating an absolute value of a difference value between a sequence number of the next bin to be picked of each picking task and a sequence number of the bin corresponding to the picking position, determining that the picking task where the next bin to be picked with the smallest bin distance to be picked is located is a third target picking task, and adding the picking position and the pre-occupied available inventory to the third target picking task to enable the third target picking task to pick missing objects. The next to-be-picked place can determine that the picking task is being executed or is about to be executed, if the next to-be-picked place does not exist, the corresponding picking task may have completed picking, and the picking task cannot be used as a third target picking task or the picking position and the pre-occupied available inventory cannot be added to the picking task.
In the embodiment of the invention, when the order picking task is executed by the order picker, in order to avoid the condition that a plurality of order pickers start to pick from the same position to cause congestion, the order picker can start to pick from any bin in the order picking task, sequentially pick the next bin with the sequence number, return to pick from the bin with the smallest sequence number after the maximum sequence number is reached, and sequentially pick according to the sequence number until the object in the order picking task is finished, thereby avoiding congestion. In this case, the picking position is located in the remaining picking path of the picking order, and then the picking position is added to the picking order, so that the picking order performs the picking of the missing items, for example, the order numbers of the stock positions required to be picked by the picking order are 1, 5, 12, 25, 32, 45 and 50, and in general, the order numbers of the pickers can be sequentially picked, i.e., 1→5→12→25→32→45, so that the items are picked, and this case is easy to cause congestion, and in order of 25→32→45→1→5→12, the pickers can pick, in order to avoid congestion, if the picking position is located in the remaining picking path of the picking order, the picking position is added to the picking order.
In the embodiment of the present invention, step S102 further includes: adding the identity of the order to the picking order being or about to be performed; therefore, the picking task picks the missing articles according to the pre-occupied available inventory at the picking position, and the picking task can distribute the picked missing articles to the corresponding orders according to the identification (such as order numbers) of the orders when the production mode is sorting while sorting or secondary sorting.
Step S103: the order is processed in succession by picking orders being executed or about to be executed to supplement items missing from the order.
In the embodiment of the invention, after the supplementary picking position and the pre-occupied available inventory are added to the picking task which is being executed or is about to be executed, the picking task which is being executed or is about to be executed continues to pick the missing article so as to complete the processing of the order with the missing amount, and compared with the mode of adding or embedding the picking of the missing article in the order to the picking task which is being executed or is about to be executed to pick, the mode of singly picking the missing article of the missing amount order or gathering the batch picking after the missing amount order is accumulated to a certain amount, the processing efficiency of the missing amount order is improved, and the processing time of the missing amount order is shortened.
In the embodiment of the invention, aiming at the condition that the order is in a sorting stage, when the order has the shortage of the articles, the order is distributed to a reserved sorting grid, and further, after the sorting task of the shortage of the articles comprising the order is completed, the sorting platform where the reserved sorting grid is located is distributed for the articles comprising the sorting task. In the secondary sorting stage, sorting is carried out at a sorting table according to a picking work order, different orders are distributed to different sorting lattices, picked articles are sowed to different orders, when the orders have the shortage articles, the orders with the shortage articles are distributed to reserved sorting lattices so as to be distinguished from the orders without the shortage, the orders are paired with the shortage articles at the later stage, after the sorting task of the shortage articles comprising the orders is completed, the sorting task is carried out at the sorting table where the shortage orders are located, and the shortage articles are distributed to reserved sorting lattices, so that the orders complete the processing of the shortage articles.
The order processing process is described in detail below by taking the pick stage, the secondary sort stage, and the review package stage as examples. The execution flow for the plurality of picking tasks is specifically shown in fig. 3, for example, in the embodiment shown in fig. 3, a plurality of picking tasks are included, and when each of the plurality of picking tasks is used as a target picking task to execute steps S301 to S312, other picking tasks except the target picking task execute steps S313 to S318. That is, each of the plurality of picking orders performs steps S301 to S311 when it is a target picking order, and performs steps S312 to S316 when it is another picking order.
Step S301: in the picking stage, picking according to the target picking task;
step S302: judging whether the target picking task has an absent article, if so, executing step S303; otherwise, step S305 is performed;
step S303: judging whether the residual picking path of the target picking task meets the picking position of the ullage object and the requirement of occupying available inventory, if so, executing step S304; otherwise, step S305 is performed;
the need for the remaining pick paths to meet the pick locations of the ullage items and to preempt available inventory is: the remaining picking paths have the same stock positions as the item identifications of the ullage items and the stock quantity is larger than the item quantity of the ullage items;
step S304: adding the picking position of the ullage item and the pre-occupied available inventory to the target picking task;
step S305: the objects sorted by the target sorting tasks enter a secondary sorting stage, and the sorted objects are sown into sorting lattices where each order is located in the secondary sorting bench;
step S306: judging whether an order for the lacking article exists in the sorting grid, if so, executing step S307; otherwise, step S311 is performed;
step S307: placing an order for the missing item (a shortage order) in a reserved sort grid;
Step S308: determining a pick location for the missing item and preempting the available inventory;
step S309: judging whether a bin matched with the picking position of the lacking article exists after the current picking bin in other picking tasks, if so, executing step S310; otherwise, ending the current flow;
the presence of a bin after the current pick bin that matches the pick location of the missing item refers to: the current picking bin is followed by a bin that has the same item identification as the missing item, which may be a bin to be picked or a bin not to be picked in the remaining picking paths of other picking tasks;
step S310: adding the pick locations of the missing items and the pre-empted available inventory to other pick tasks and performing step 315;
step S311: the order after the secondary sorting enters a rechecking and packaging stage, and the goods are rechecked and packaged in a packaging table;
step S312: judging whether an order for the lacking article exists in the composite packaging process, and if so, executing a step S307; otherwise, ending the current flow;
step S313: other picking tasks enter a picking stage, and picking is carried out according to the other picking tasks;
step S314: judging whether a newly added picking position exists or not and preempting available inventory exists, if so, executing step S315; otherwise, step S316 is performed;
Step S315: generating new picking paths for other picking tasks according to the residual picking paths of the other picking tasks and the newly added picking positions;
step S316: picking items according to the new picking path and performing step S318;
step S317: picking items according to the remaining picking paths;
step S318: and (3) sequentially carrying out secondary sorting stage and rechecking packaging stage on the articles sorted by other sorting tasks, supplementing the reserved sorting grids with the missing articles, and ending the current flow.
Supplementing the reserved sorting lattices with the missing articles refers to other sorting tasks sowing the articles to the sorting lattice where each order is located at the secondary sorting bench, supplementing the missing articles to the reserved sorting lattice where the order of the missing articles is located, and completing pairing with the order of the missing articles.
