It is obvious, however, that one or more embodiments may be implemented without these specific details. In addition, in the following descriptions, descriptions of well-known structures and technologies are omitted to avoid unnecessarily obscuring the concept of the present disclosure.

As shown in
Some trigger conditions may be set for the ex-warehouse container, and the ex-warehouse container may be delivered when the trigger conditions are met. These trigger conditions may be, for example, that the number of orders of multi-item orders in the ex-warehouse container is greater than 10, the number of orders of single-item orders is larger than 20, a slot in the ex-warehouse container is full, the number of items of a multi-item order is greater than 20, or a certain time limit is reached, etc.
However, this method tends to cause buffer locations in front of the workstation to be full, occupying the main road and causing congestion, and fewer items may be picked by moving the shelf each time, and the picking efficiency is low.
In this regard, the embodiments of the present disclosure provide a method of order scheduling, including determining a target buffer location from a plurality of shelf buffer locations of a workstation, acquiring shelf information of a plurality of shelves, wherein the shelf information includes item information of items carried on each shelf of the plurality of shelves, acquiring a plurality of orders to be processed, including at least one unactivated order and at least one activated but uncompleted order, determining a next shelf to be moved to the workstation based on the shelf information and the orders to be processed, outputting control information to move the shelf to the target buffer location; and determining a part of orders to be processed from the plurality of orders to be processed as orders to be picked based on items carried on shelves moved to the plurality of shelf buffer locations.
The embodiments of the present disclosure focus on a shelf, and subvert a picking method that focuses on an order. When a shelf buffer location of a workstation is in an idle state, a shelf is recommended. For example, a shelf on which more items may be picked out may be selected and moved to the workstation, which may effectively increase a number of the items picked from each shelf, thereby improving the picking efficiency. Different from a traditional order scheduling algorithm, in the embodiments of the present invention, the ex-warehouse container is basically not used as a constraint condition for scheduling orders. In this way, if necessary, the ex-warehouse container may be closed at any time to free up a new ex-warehouse container for a new order.
In the embodiments of the present disclosure, a trigger condition set for the ex-warehouse container may be, for example, that there is no open order in the container.
It should be understood that the number of orders, shelves, workstations and ex-warehouse containers in
As shown in
In operation S210, a target buffer location is determined from a plurality of shelf buffer locations of a workstation.
According to the embodiments of the present disclosure, status information of the plurality of shelf buffer locations may be acquired, and a shelf buffer location in an idle state is determined from the plurality of shelf buffer locations as the target buffer location according to the status information.
In operation S220, shelf information of a plurality of shelves is acquired, and the shelf information includes item information of items carried on each shelf of the plurality of shelves.
In operation S230, a plurality of orders to be processed are acquired, including at least one unactivated order and at least one activated but uncompleted order.
According to the embodiments of the present disclosure, an activated but uncompleted order may also be referred to as an open order, or an opened order. Different from the related art, the method of the embodiments of the present disclosure does not pre-occupy the ex-warehouse container according to a pre-defined collection order, and allows a plurality of open orders to exist on one workstation at the same time. Therefore, the method of the embodiments of the present disclosure may take a plurality of unactivated orders and activated but uncompleted orders into account, so as to realize more efficient picking.
In operation S240, a next shelf to be moved to the workstation is determined based on the shelf information and the orders to be processed.
Since there is no pre-occupying of ex-warehouse containers, there is more freedom in selecting shelf and scheduling order. For example, a shelf on which more items may be picked out may be selected, which may effectively improve the picking efficiency.
For example, for shelf A, shelf B, and shelf C, the number of pickable items in shelf A is 5, the number of pickable items in shelf B is 7, and the number of pickable items in shelf C is 2, and it may be determined that shelf B is the next shelf to be moved to the workstation.
As shown in
In operation S310, for each shelf of the plurality of shelves, a number of pickable items carried on the shelf is determined as a first score for the shelf, wherein the pickable items include items in the plurality of orders to be processed, or items in the at least one activated but uncompleted order.
Generally, items to be picked for the orders to be processed are the pickable items. However, there may be exceptions. For example, the workstation may hold a limited number of ex-warehouse containers. When the number of the activated but uncompleted orders reaches a certain number, if the ex-warehouse containers are filled after completing these activated but uncompleted orders, then it is impossible to activate a new order. In this case, the pickable items are items required by the activated but uncompleted orders, and do not include items required by the unactivated orders.
For example, for shelf A, shelf B, and shelf C described above, a first score for shelf A is 5, a first score for shelf B is 7, and a first score for shelf C is 2. In order to integrate with a second score and make it easier to control contribution of the two scores to a final result, the first score may be determined after normalizing the number. In this case, the first score for shelf A is 5/14, the first score for shelf B is 1/2, and the first score for shelf C is 1/7.
According to the embodiments of the present disclosure, an inverted index of the items included in the order may be established, a corresponding order may be found according to a list of items included in the shelf, and then whether it is an order to be picked may be determined according to the method of S260 described below with reference to
In operation S320, for each shelf of the plurality of shelves, a degree of urgency of the items carried on the shelf is determined as a second score for the shelf.
According to the embodiments of the present disclosure, the degree of urgency of the items may be determined based on a length of time to an order delivery deadline. Different degrees of urgency may be determined for different lengths of time to the delivery deadline of the order. As the remaining time shortens, the degree of urgency of the item increases. For example, a reciprocal of the remaining time may be set as the degree of urgency, and when the time to the order delivery deadline is 3 hours, 2 hours, 1 hour, 30 minutes, the degree of urgency may be determined as ⅓, ½, 1, 2. The results described above may also be normalized according to the longest time and the shortest time to the order delivery deadline, and the normalized results may be regarded as the degree of urgency.
According to the embodiments of the present disclosure, the degree of urgency of the items may be determined based on a completion degree of the activated but uncompleted order. For example, an order has been activated, that is, the order is in a state of being activated but not completed. The order requires a total of 5 items to be picked. Currently, 3 items have been picked, and the completion degree is 60%. If 4 items have been picked, the completion degree is 80%. The degree of urgency may be determined based on the completion degree. Simply, the completion degree may be directly used as the degree of urgency.
According to the embodiments of the present disclosure, the two degrees of urgency described above may be used independently to determine the second score, or may be used in combination to jointly determine the second score. For example, in a case that a length of time to a delivery deadline of an activated but uncompleted order is 1 hour, and a completion degree of the activated but uncompleted order is 80%, the degrees of urgency determined in the two ways may be normalized respectively, weighted and summed to acquire a second score.
In operation S330, the next shelf to be moved to the workstation is determined from the plurality of shelves based on the first score and the second score. For example, a final score may be determined by selecting the way of adding, weighted summing or multiplying the two scores. Based on the final score for each shelf, an optimal shelf is determined as the next shelf to be moved to the workstation.
According to the embodiments of the present disclosure, the determining a next shelf to be moved to the workstation based on the shelf information and the orders to be processed further includes monitoring the order delivery deadline, and prioritizing an urgent order in a case that the delivery deadline of the urgent order is smaller than a first threshold.
According to the embodiments of the present disclosure, the orders to be processed may include a time limited order different from an ordinary order, and the time limited order has a higher time limit requirement than the ordinary order. The method of the embodiments of the present disclosure may monitor a processing status of the time limited order independently, and after a certain time is reached, the time limited order may be forcibly processed, regardless of how many items required by other orders may be obtained from the shelf, so as to ensure that the time limited order is completed within a specified time limit.
Referring back to
According to the embodiments of the present disclosure, outputting control information to move the shelf to the target buffer location includes sending the control information to a transfer robot to control the transfer robot to move the shelf to the workstation. The transfer robot may be, for example, an automated guided vehicle (AGV), and the AGV may be controlled to move the shelf to the target buffer location in the workstation.
According to the embodiments of the present disclosure, the outputting control information to move the shelf to the target buffer location includes sending the control information to the shelf to control the shelf to move to the target buffer location. In the embodiments of the present disclosure, a smart shelf may be used, and a bottom of the smart shelf may be provided with universal wheels, and may also include a communication device, a processor, and a driving device. When receiving control information through the communication device, the processor may parse the control information and generate a control signal to move the shelf to the target buffer location in the workstation through the driving device.
In operation S260, a part of orders to be processed is determined from the plurality of orders to be processed as orders to be picked based on items carried on shelves moved to the plurality of shelf buffer locations.
According to the embodiments of the present disclosure, the orders to be picked may be a collection order, which is used to characterize which orders are about to enter a picking process.
According to the embodiments of the present disclosure, the activated but uncompleted order in the orders to be processed may be regarded as the order to be picked.
According to the embodiments of the present disclosure, the order to be picked may be determined from the unactivated orders in various manners, which will be described separately below. It should be noted that the following manners may be used individually or in combination, which is not limited in the present disclosure.
For example, a ratio of each order to be processed in the plurality of orders to be processed satisfied by the shelves currently in the plurality of shelf buffer locations is determined as a coverage ratio, and one or more orders to be processed with the coverage ratio higher than a second threshold are determined as the orders to be picked. For example, the second threshold may be preset to 50%. When there is an order in the unactivated orders whose completion degree may exceed 50% by picking the items on the shelves currently docked at the workstation, in other words, when the items on the shelves docked at the workstation cover 50% of the order, the order may be determined as an order to be picked.
For another example, one or more complex orders in the plurality of orders to be processed may be regarded as the orders to be picked, the complex order is an order with a number of categories of the items contained greater than a third threshold. For example, the third threshold may be set to 3. When an order contains more than 3 categories of items, at least 3 shelves are required to meet a picking requirement of the order, and the order is determined as a complex order. If the current shelves may meet some of the items in the complex order, the complex order may be regarded as the order to be picked.
For another example, a part of orders to be processed from the plurality of orders to be processed may be determined as orders to be picked based on the length of time to the order delivery deadline. For example, in the case where an order is 3 hours, 2 hours, 1 hour, 30 minutes, etc. to the order delivery deadline, different degrees of urgency may be determined, and as the remaining time becomes shorter, the degree of urgency increases. A weight value may be determined according to the degree of urgency, so as to determine whether the order is determined as an order to be picked, or the order may be forcibly determined as an order to be picked when the time is less than a preset value.
According to the embodiments of the present disclosure, the method described above or other methods may be used to determine the weight value respectively, make a comprehensive evaluation, and then determine whether to determine the order as an order to be picked.
An original mode determines a shelf that needs to be transported to a workstation and a shelf buffer location corresponding to the shelf according to a pre-generated collection order. The shelf and shelf buffer location are occupied prematurely, which may cause buffer locations in front of a workstation to be full, occupying a main road and causing congestion, resulting in a low picking efficiency. The method of the embodiments of the present disclosure no longer schedules a shelf according to the pre-generated collection order, but comprehensively considers the unactivated order, the activated but uncompleted order and the shelf information to determine a shelf to be scheduled to the workstation buffer locations, and then determines an order to be picked, which may avoid pre-occupying resources such as shelves and shelf buffer locations or pre-occupy the resources at a late point, and improve a problem of low picking efficiency in the original mode.
In addition, the method of the embodiments of the present disclosure comprehensively considers the unactivated order, the activated but uncompleted order and the shelf information to jointly determine a shelf to be scheduled, which may increase an average number of picking pieces of the shelf and improve the picking efficiency. A main idea of the method of the embodiments of the present disclosure is to avoid pre-occupying any scheduling input or pre-occupy any scheduling input at a late point, including the order, the shelf, the ex-warehouse container, and the buffer location, which avoids a failure of expected scheduling order optimization caused by various anomalies, and at the same time, making late decisions is also conducive to accumulating more orders and optimizing other inputs in a timely manner.
According to the embodiments of the present disclosure, after the shelf is moved to the workstation, there may be a computer system or a display communicatively connected to a computer system on the workstation, which is used to prompt the staff which items to pick. It is also possible to set up a robotic arm instead of manual picking, so that the robotic arm may be directly controlled to perform picking without a display. The following describes a process of determining the item to be picked with reference to the embodiment shown in
As shown in
In operation S410, at least one ex-warehouse container corresponding to the order to be picked is determined, and the items are picked by using the at least one ex-warehouse container.
According to the embodiments of the present disclosure, at least one ex-warehouse container may be allocated according to the type and number of the items in the order to be picked, and is used to load the items in the order to be picked during an ex-warehouse process.
According to the embodiments of the present disclosure, information of one or more items in the order to be picked may be displayed on a display, so that the staff may pick the items according to the information of the items, or the robotic arm may be controlled to grab one or more items indicated by the order to be picked into the ex-warehouse container.
According to the embodiments of the present disclosure, the ex-warehouse container is scheduled only after the order to be picked is determined, so that pre-occupancy of the ex-warehouse container may be avoided, thereby making the scheduling of the ex-warehouse container more flexible.
Based on the same inventive concept, the embodiments of the present disclosure further provide an apparatus of order scheduling, and the apparatus of order scheduling of the embodiments of the present disclosure will be described below with reference to

According to the embodiments of the present disclosure, the system, device, apparatus, module, unit, etc. described above may be implemented by the computer program module.
The present disclosure further provides a computer-readable medium. The computer-readable medium may be included in the device/apparatus/system described in the above-mentioned embodiments, and may also exist alone without being assembled into the device/apparatus/system. The computer-readable medium described above carries one or more programs, and when the one or more programs are executed, the method according to the embodiments of the present disclosure may be implemented.
According to the embodiments of the present disclosure, the computer-readable medium may be a computer-readable signal medium or a computer-readable storage medium, or any combination thereof. The computer-readable storage medium may be, for example, but not limited to, an electrical, magnetic, optical, electromagnetic, infrared, or semiconductor system, apparatus or device, or any combination of the above. More specific examples of the computer readable storage media may include, but are not limited to, an electrical connection with one or more wires, a portable computer disk, a hard disk, a random access memory (RAM), a read only memory (ROM), an erasable programmable read only memory (EPROM or flash memory), an optical fiber, a portable compact disk read only memory (CD-ROM), an optical storage device, a magnetic storage device, or any suitable combination of the above. In the present disclosure, the computer-readable storage medium may be any tangible medium that contains or stores a program that may be used by or in conjunction with an instruction execution system, apparatus, or device. In the present disclosure, the computer-readable signal medium may include a data signal propagated in a baseband or as part of a carrier wave, which carries computer-readable program code. Such a propagated data signal may take a variety of forms, including but not limited to, an electromagnetic signal, an optical signal, or any suitable combination of the above. The computer-readable signal medium may also be any computer-readable medium other than the computer-readable storage medium, and the computer-readable medium may transmit, propagate, or transport a program that may be used by or in conjunction with the instruction execution system, apparatus, or device. Program code contained on the computer readable medium may be transmitted using any suitable medium including, but not limited to, a wireless, wired, optical fiber cable, radio frequency signal, etc., or any suitable combination of the above.
For example, according to the embodiments of the present disclosure, the computer-readable medium may include one or more memories other than the ROM 602 and/or the RAM 603 and/or the ROM 602 and the RAM 603 described above.
The flowchart and block diagrams in the drawings illustrate the architecture, functionality, and operation of possible implementations of systems, methods and computer program products according to various embodiments of the present disclosure. In this regard, each block in the flowchart or block diagrams may represent a module, program segment, or part of code, which contains one or more executable instructions for implementing the specified logical function. It should also be noted that, in some alternative implementations, the functions noted in the blocks may occur out of the order noted in the drawings. For example, two blocks shown in succession may, in fact, be executed substantially concurrently, or the two blocks may sometimes be executed in a reverse order, depending upon the functionality involved. It should also noted that each block of the block diagrams or flowchart illustrations, and combinations of the blocks in the block diagrams or flowchart illustrations, may be implemented by using a special purpose hardware-based system that performs the specified functions or operations, or may be implemented using a combination of a special purpose hardware and computer instructions.
