Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart of a transportation path determining method according to an embodiment of the present invention, which is applicable to determining a transportation path of a transportation vehicle when an article is returned to a warehouse or when an article is put into a warehouse. The method may be performed by a transportation path determination apparatus, which may be implemented by software and/or hardware, integrated in a device with data processing function, such as a computer, and the like. As shown in fig. 1, the method specifically includes the following steps:
and S110, determining each target article storage container to be warehoused or warehoused in the transport vehicle.
The article storage container is a transportable container for storing articles in the warehouse, so that the articles in the warehouse can be transported to a workstation for picking and other operations by transporting the article storage container. For example, the item storage container may be, but is not limited to, a bin. The target article storage container may refer to an article storage container that is transported out of the warehouse and needs to be returned to the warehouse for shelving. The target article storage container may be an article storage container that is transported at the warehousing workstation and needs to be warehoused and shelved. The number of the target item storage containers may be at least two. The transport vehicle may refer to an unmanned transport vehicle that can transport a plurality of article storage containers at a time. For example, the transport vehicle may be, but is not limited to, a multi-level bin unmanned vehicle AGV such that the unmanned vehicle AGV may simultaneously transport multiple bins.
Specifically, in the operation of delivering the articles out of the warehouse, a plurality of article storage containers can be positioned in the warehouse according to the current article requirements of the delivery workstation, the transport vehicle is controlled to sequentially take out the article storage containers from a plurality of positions and transport the article storage containers to the delivery workstation together for carrying out article picking operation, when the article picking operation is completed in the delivery workstation, the article storage containers need to be transported back to the warehouse again, and at the moment, each article storage container transported by the transport vehicle can be determined as a target article storage container to be delivered back to the warehouse; the sorted non-empty storage containers may also be determined as target storage containers to be returned to the warehouse to ensure that the sorted empty storage containers are not returned to the warehouse. In the warehousing operation of the articles, the transport vehicle may directly go to the warehousing workstation to transport the loaded article storage containers to be warehoused and shelved (the empty article storage containers sorted in the scene are not returned to the warehouse any more), or the transport vehicle may transport the article storage containers in the warehouse to the warehousing workstation to carry out article loading, so that the loaded article storage containers need to be transported back to the warehouse.
And S120, grouping the target article storage containers according to the target article information corresponding to the target articles stored in the target article storage containers, and determining a container group and a target channel corresponding to the container group.
The target items stored in the target item storage container may be one or more items. The target item information may include, but is not limited to: target item name information and target item popularity information. The target item popularity information may refer to popularity of the target item, such as frequency of warehouse-out of the target item or frequency of purchase of the user. The container group may be a set of at least one target item storage container. The group of containers may be one or more. The target aisle may refer to an aisle in the warehouse where shelves for storing individual target item storage containers in the group of containers are located.
Specifically, all the target article storage containers may be grouped according to the target article information in each target article storage container, each target article storage container meeting the preset grouping condition is divided into one group, so as to obtain each container group, and the target channel corresponding to each container group is determined in the form of the container group. For example, according to the name information of the target items in each target item storage container, the target item storage containers that are simultaneously present in the same historical order may be divided into one group, or the target item storage containers belonging to the same item category may be divided into one group, for example, the target item storage containers in which the stored target items are snacks may be divided into one group, so that the adjacent target item storage containers are stored in the same channel, so that the distribution of the item storage containers is reasonable, the subsequent delivery is facilitated, and the delivery efficiency is improved.
And S130, determining a target transportation path corresponding to the transport vehicle according to the target channel and the current position of the transport vehicle.
The current position of the transport vehicle may refer to a current position of the transport vehicle. For example, at an initial time, the current location of the transporter may be the location of an outbound workstation or the location of an inbound workstation. The target transport path may refer to a travel path in which the transport vehicle travels from the current position to the target aisle corresponding to each container group.
Specifically, path planning may be performed based on the channel position of the target channel corresponding to each container group and the current position of the transport vehicle, and the planned shortest path is determined as the target transport path, so that the transport vehicle may transport each target article storage container in each container group to the corresponding target channel for returning to the warehouse or putting on shelf in the warehouse based on the target transport path, thereby quickly completing the operation of returning articles to the warehouse or putting on shelf in the warehouse by using fewer channels, further reducing the transport distance, and improving the transport efficiency during the warehouse entry or the warehouse return.
According to the technical scheme, the target object storage containers to be warehoused or warehoused in the transport vehicle are determined, the target object storage containers are grouped according to the target object information corresponding to the target objects stored in the target object storage containers, the container group and the target channel corresponding to the container group are determined, the target channel corresponding to the container group is obtained in the form of the container group, the target transport path corresponding to the transport vehicle is determined according to the target channel and the current position of the transport vehicle, the transport vehicle can transport the target object storage containers in the container group to the target channel to be warehoused or warehoused, all the target object storage containers can be distributed to fewer channels, the transport distance is reduced, and the transport efficiency during warehousing or warehousing is improved.
On the basis of the above technical solution, S120 may include: grouping the target article storage containers according to the target article heat degree information corresponding to the target articles stored in the target article storage containers, and determining container groups and container group heat degrees corresponding to the container groups; and determining a target channel corresponding to the container group according to the heat of the container group.
The container group heat may refer to a comprehensive heat of the target items stored in the respective target item storage containers in the container group. The container group popularity may be used to characterize the popularity of the container group, such as the ex-warehouse frequency of the container group. When the container group corresponding to the container group is higher in popularity, the better the popularity of the container group is, the higher the frequency of purchasing the target articles in the container group by the user is, so that the ex-warehouse frequency of the container group is also higher.
Specifically, the target item storage containers belonging to the same heat range may be divided into one container group according to the target item heat information corresponding to the target item stored in each target item storage container, so that the heat of each container group and the container group corresponding to each container group may be obtained. Based on the container group heat, a lane in the warehouse that matches the container group heat may be determined as the target lane. For example, the higher the heat of the container group is, the closer the distance between the target channel and the delivery workstation is, so as to ensure that the articles with high heat are stored in the channel close to the delivery workstation, and the articles with low heat are stored in the channel far away from the delivery workstation, so that the target article storage containers are reasonably distributed based on the heat, the subsequent delivery is facilitated, and the delivery efficiency is further improved.
On the basis of the above technical solution, S130 may include: in the target channel, determining a target storage position corresponding to each target article storage container in the container group; determining a target storage sequence according to each target storage position and the current position of the transport vehicle; and according to the target storage sequence, determining the target transportation path corresponding to the transport vehicle.
The target storage position may refer to a shelf position for storing the target storage container in two rows of shelves on the left and right of the target aisle. The target storage sequence may refer to a sequence of arrival of all target storage positions corresponding to all target article storage containers, so that the transport vehicle may store each target article storage container according to the target storage sequence.
Specifically, for each container group, according to whether an article storage container is stored at each storage position in the target passage corresponding to the container group at the current time, an empty storage position where no article storage container is currently stored in the target passage may be determined. The number of empty storage locations in the target aisle is greater than or equal to the number of containers of the target item storage containers in the group of containers. If the number of the positions is larger than the number of the containers, the number of the empty storage positions, which is the nearest to the current position of the transport vehicle, can be selected from the empty storage positions, so that the carrying distance is further shortened, and the transport efficiency during warehousing or warehousing is improved. When the number of empty storage positions of the containers in the target passage is obtained, an empty storage position can be randomly allocated to each target article storage container to serve as a corresponding target storage position; the target article storage containers are arranged in a descending order to obtain a target article storage container sequence based on the container heat degree of each target article storage container, the empty storage positions are arranged in an ascending order based on the distance between each empty storage position and the ex-warehouse workstation to obtain an empty storage position sequence, and the target article storage container sequence and the empty storage position sequence are in one-to-one correspondence, so that the target storage position corresponding to each target article storage container in the container group is determined, the target article storage containers with higher container heat degrees are stored at the empty storage positions which are closer to the ex-warehouse workstation to facilitate subsequent ex-warehouse, and the ex-warehouse efficiency is further improved. When the target storage positions corresponding to each target article storage container are determined, the sequential shelving sequence corresponding to the shortest carrying distance, namely the target storage sequence, can be determined according to the target storage positions and the current position of the transport vehicle, and based on the target storage sequence, the shortest path between the current position of the transport vehicle and the first target storage position and the shortest path between two adjacent target storage positions can be determined by means of the preset shortest path, so that the optimal target transport path corresponding to the transport vehicle can be obtained, the carrying distance is further shortened, and the transport efficiency during warehousing or warehousing is improved. The preset shortest path mode may be, but is not limited to, Dijkstra mode or a star (a-star) mode.
Illustratively, a preset shortest path mode can be utilized, and based on historical road network congestion information and warehouse road network connectivity, a driving path corresponding to the shortest driving time between two positions is determined, so that a target transportation path corresponding to the shortest driving time can be obtained, the transportation time is further shortened, and the transportation efficiency is improved.
It should be noted that the storage position corresponding to each article storage container in the warehouse is dynamically changed, so that the flexibility of article delivery from the warehouse can be improved, and the condition that all transport vehicles go to the position to cause road condition congestion during fixed storage is avoided.
Illustratively, determining the target storage order based on the respective target storage locations and the current location of the transporter may include: determining the shortest path between each target storage position and each two positions in the current position of the transport vehicle based on a preset shortest path mode; based on the shortest paths, a target deposit order is determined.
Specifically, the shortest path between each two locations may be determined according to connectivity of the warehouse road network based on a preset shortest path manner. Based on each shortest path, a target storage sequence corresponding to each target storage position may be determined in a traversal enumeration manner or by using a TSP (tracking Salesman publishing, a travel business Problem) model. For example, a matching manner may be selected based on the number of target storage locations, so as to determine the target storage sequence more quickly, thereby improving the transportation path determination efficiency. For example, if the number of the target storage locations is less than or equal to the preset number (for example, the preset number may be 4), the total transportation distance corresponding to each storage order may be calculated based on the transportation distance corresponding to each shortest path by directly adopting a traversal enumeration manner, and the storage order corresponding to the minimum total transportation distance may be determined as the target storage order. If the number of the target storage positions is larger than the preset number, the TSP model can be directly adopted to more quickly determine the target storage sequence. For example, a distance matrix is determined based on the corresponding travel distance for the shortest path between each two locations. The transport vehicle does not need to return to the starting point after loading the last target article storage container, so that the distance from each target storage position in the determined distance matrix to the current position of the transport vehicle is updated to 0, the updated distance matrix is input into a preset TSP model, the output storage sequence output by the TSP model is obtained, the output storage sequence is adjusted, the current position of the transport vehicle in the output storage sequence is used as the initial point, and the adjusted output storage sequence is determined as the target storage sequence. For example, if the current position of the transportation vehicle is W, and the five target storage positions are A, B, C, D and E, respectively, the output storage sequence of the TSP model output is: AEDWCB, then the initial point in the output deposit order is A, need be through the mode of circulation this moment, will adjust initial point for transport vechicle current position W, and the deposit order after the adjustment promptly is CBAED, deposits the order as the target to can utilize the TSP model to determine the target faster and deposit the order, and then improved the transport route and confirm efficiency.
Example two
Fig. 2 is a flowchart of a transportation route determining method according to a second embodiment of the present invention, and in this embodiment, optimization is performed on "grouping each target item storage container according to target item heat information corresponding to a target item stored in the target item storage container, and determining a container group and a container group heat corresponding to the container group" according to the second embodiment of the present invention. On the basis, the target channel corresponding to the container group can be further determined according to the heat of the container group, and optimization can be further carried out. Wherein explanations of the same or corresponding terms as those of the above embodiments are omitted.
Referring to fig. 2, the method for determining a transportation route provided by this embodiment specifically includes the following steps:
s210, determining each target article storage container to be warehoused or warehoused in the transport vehicle.
S220, determining the target container heat degree corresponding to each target article storage container according to the target article heat degree information corresponding to the target articles stored in the target article storage container.
The target container heat may refer to a comprehensive heat of the target item stored in the target item storage container. The target container heat may be used to characterize the frequency of the target item storage container being out of stock. When the target container is hot, the user is indicated to purchase the target item in the target item storage container more frequently, so that the target item storage container is taken out of the warehouse more frequently.
Specifically, an average ex-warehouse order amount and an average ex-warehouse interval number of each article in the warehouse within a preset time may be determined in advance based on the historical order information, and an article heat corresponding to each article in the warehouse may be determined based on the average ex-warehouse order amount and/or the average ex-warehouse interval number of the articles. For example, the average delivery order amount or the average number of delivery rooms for the article may be directly determined as the article popularity corresponding to the article, or the average delivery order amount and the average number of delivery rooms may be weighted and summed, and the result of the summation may be determined as the article popularity corresponding to the article. For each target item storage container, the target container heat corresponding to the target item storage container may be determined according to the target item heat corresponding to the target item stored in the target item storage container. For example, if only one kind of target item is stored in the target item storage container, the target item heat corresponding to the one kind of target item is determined as the target container heat corresponding to the target item storage container. And if at least two target articles are stored in the target article storage container, comparing the target article heat corresponding to each target article, and determining the maximum target article heat as the target container heat corresponding to the target article storage container.
Illustratively, S220 may include: acquiring the storage quantity and the target article heat corresponding to each target article stored in a target article storage container; and determining the target container heat corresponding to the target article storage container according to the storage quantity corresponding to the target articles and the target article heat.
Specifically, the target item heat corresponding to each target item stored in the target item storage container may be obtained according to an item heat corresponding to each item in the warehouse obtained in advance, and the storage quantity of each target item in the target item storage container may be obtained. A target container heat corresponding to the target item storage container may be determined based on the following formula:
Figure BDA0002500748310000121
wherein HiThe target container heat corresponding to the ith target article storage container is indicated; i issRefers to a collection of target items stored in a target item storage container; s is a set of target items IsAny one of the target articles of (1); q. q.ssThe storage quantity of the target objects s is defined; h issIs the target item heat corresponding to the target item s. Through based on target article heat and deposit quantity, can determine more reasonable target container heat to when avoiding only confirming target container heat based on article heat, place the condition in the position apart from leaving warehouse workstation nearest with the high target article storage container that nevertheless deposit quantity of article heat, make the container distribute more rationally, further improve the efficiency of leaving warehouse.
And S230, grouping the target article storage containers according to the heat of the target containers to determine a container group.
Specifically, a plurality of heat ranges may be set based on a preset heat interval, and target item storage containers in the same heat range may be divided into one group, so that each container group may be obtained.
Illustratively, S230 may include: determining a target container heat degree range corresponding to each target article storage container according to the target container heat degree and preset range control parameters; and dividing each target article storage container with the overlapped part of the target container heat range into one group as a container group.
Wherein the target container heat range may refer to a dynamic allowable heat range of the target item storage container.
Specifically, the target container heat range F corresponding to the target article storage containeriIt can be determined that:F ＝[Hi·(1-α),Hi/(1-α)]or Fi＝[Hi·(1-α),Hi·(1+α)]Wherein the preset range control parameter alpha epsilon (0, 1). And comparing the target container heat degree ranges corresponding to each target article storage container, determining whether an overlapping part exists between every two target container heat degree ranges, and when the overlapping part exists, indicating that the difference between the target container heat degree ranges is not large, so that each target article storage container with the overlapping part can be divided into one group to be used as a container group. For example, if there is an overlapping portion of the target-article storage container a and the target-article storage container B, an overlapping portion of the target-article storage container B and the target-article storage container C, and an overlapping portion of the target-article storage container D and the target-article storage container E, ABC may be divided into one group and DE may be divided into one group, thereby obtaining two container groups. By dividing the target container heat range corresponding to each target article storage container, each container group can be determined quickly and accurately.
S240, determining the heat of the container group corresponding to the container group according to the heat of the target container corresponding to each target article storage container in the container group.
Specifically, the maximum target container heat in the container group may be determined as the container group heat corresponding to the container group; alternatively, the target container heat corresponding to each target article storage container in the container group may be averaged, and the obtained average value may be determined as the container group heat corresponding to the container group.
And S250, determining the heat proportion corresponding to the container group according to the heat of the container group and the heat of the existing container corresponding to the existing article storage container in the warehouse.
Wherein, the heat proportion can be used for measuring the heat of the container group in all the existing container heats. For example, if the heat level of a container group is equal to the maximum heat level of an existing container, it indicates that the heat level of the container group is the highest.
Specifically, the existing container heat corresponding to each existing article storage container in the warehouse may be determined in the same manner as the determination of the target container heat, and the heat proportion of the container group heat to all existing container heat may be determined by comparing the container group heat to each existing container heat. For example, among all the existing container heats, the number of the existing container heats greater than or equal to the container group heat is determined, and the ratio of the number to the total number of the existing container heats is determined as the heat proportion.
And S260, determining a target channel corresponding to the container group according to the heat proportion and a preset channel sequence, wherein the preset channel sequence is obtained by sequencing based on the carrying distance between each channel in the warehouse and the ex-warehouse workstation.
Wherein, the preset channel sequence can be used for representing the distance between each channel and the ex-warehouse workstation. Specifically, the channels may be arranged in an ascending order based on the conveying distance between each channel and the ex-warehouse workstation, so as to obtain a preset channel sequence. From predetermineeing the passageway sequence, can select the passageway with the heat proportion assorted, as the target channel, for example with carrying apart from the passageway that the proportion equals with the heat proportion as the target channel to in carrying the high container group of heat to the target channel that is close to the work station of leaving warehouse, guaranteed the principle that the good products are close to the work station of leaving warehouse and deposit, avoid article to deposit the confusion, be convenient for follow-up leaving warehouse, and then improved the efficiency of leaving warehouse.
Illustratively, the sorting based on the carrying distance between each channel in the warehouse and the ex-warehouse workstation to obtain the preset channel sequence may include: acquiring a first carrying distance between each row of shelves in each channel in the warehouse and the ex-warehouse workstation; determining a second carrying distance corresponding to each channel according to the first carrying distance and the historical road condition congestion information corresponding to each row of shelves; and sequencing all channels in the warehouse based on the second carrying distance to obtain a preset channel sequence.
Wherein, the ex-warehouse work station can be one or more. Each aisle may include two rows of shelves, and each row of shelves may include multiple columns of shelves for holding article storage containers. The first handling distance may refer to the actual distance between each column of shelves in each aisle and the outbound workstation. The second transportation distance may be an estimated distance corresponding to transportation time obtained by weighting the first transportation distance using the traffic congestion information of the historical road conditions.
Specifically, the carrying distance weight value corresponding to each row of shelves may be determined based on the historical traffic congestion information corresponding to each row of shelves. The carry distance weight value is a value greater than 1. If the historical road conditions of a certain row of shelves are more congested, the heavier the weight value of the corresponding carrying distance of the row of shelves is. For example, the second conveying distance corresponding to each channel may be determined by the following formula:
Figure BDA0002500748310000141
wherein L isaIs a second handling distance corresponding to channel a in the warehouse; maRefers to the collection of each row of shelves in the channel a; m is MaAny of the columns of shelves; k is the set of ex-warehouse workstations; k is any ex-warehouse workstation in K; l ismkIs the first transport distance between the mth row of shelves and the ex-warehouse workstation k; r ismkIs the weight value of the conveying distance corresponding to the mth row of goods shelves; i MaI is the total number of rows of shelves in channel a; and | K | is the total number of ex-warehouse workstations. By congestion signalling based on historical road conditionsAnd adjusting the first conveying distance between each row of shelves in each channel and the ex-warehouse workstation to obtain a second conveying distance which is in direct proportion to the conveying time, for example, the shorter the second conveying distance is, the less the required conveying time is, so that each channel is arranged in an ascending order based on the second conveying distance to obtain a preset channel sequence for representing the conveying time, the articles with higher heat can be ex-warehouse faster, the article distribution is further optimized, and the ex-warehouse efficiency is improved.
Illustratively, S260 may include: determining a seed channel corresponding to the volume group according to the heat proportion and a preset channel sequence; and determining a target passage corresponding to the container group according to the first number of the empty storage positions in the seed passage and the second number of the target article storage containers contained in the container group. The empty storage position may refer to a storage position in which no article storage container is stored in the seed passage.
Specifically, the heat proportion and the total number of channels may be multiplied and rounded to obtain a channel ordinal number, and a channel corresponding to the channel ordinal number in the preset channel sequence may be determined as a seed channel, so that a seed channel matched with the heat proportion may be obtained. A target aisle containing a seed aisle may be determined by comparing a first number of empty storage locations in the seed aisle to a second number of target item storage containers contained in the group of containers.

Specifically, if it is detected that the first number of empty storage positions in the seed channel is greater than or equal to the second number of target article storage containers included in the container group, it indicates that all the target article storage containers in the container group can be stored in the seed channel at the same time, and at this time, the seed channel may be directly determined as the target channel corresponding to the container group. If the first number of the empty storage positions in the seed channel is smaller than the second number of the target object storage containers contained in the container group, the first number indicates that all the target object storage containers in the container group cannot be stored in the seed channel at the same time, so that the method can be stopped when the seed channel is used as the center and is gradually expanded to the adjacent channels in the periphery until the total number of the empty storage positions in the seed channel and the expanded adjacent channels is larger than or equal to the second number, at this time, the seed channel and the expanded adjacent channels can be determined as the target channels corresponding to the container group, so that all the target object storage containers in the container group can be stored in the seed channel and the adjacent channels in the periphery, the carrying distance is further reduced, and the transportation efficiency during warehousing or returning is improved.
And S270, determining a target transportation path corresponding to the transport vehicle according to the target channel and the current position of the transport vehicle.
According to the technical scheme, the target channel is determined according to the target article heat information corresponding to the target articles stored in the target article storage container and the preset channel sequence, the principle that good articles are stored close to the ex-warehouse workstation can be guaranteed while the transportation efficiency is improved, article storage disorder is avoided, article distribution is more reasonable, subsequent ex-warehouse is facilitated, and ex-warehouse efficiency is improved.
