Turning now to the drawings, the detailed description set forth below in connection with the appended drawings is intended as a description of various configurations and is not intended to represent the only configurations in which the concepts described herein may be practiced. The detailed description includes specific details for the purpose of providing a thorough understanding of various concepts with like numerals denote like components throughout the several views. However, it will be apparent to those skilled in the art that these concepts may be practiced without these specific details.

Goods replenishment and distribution center stocking scheme are essential components of high volume distribution and fulfillment operations. Generally, a distribution center receives multiple stock keeping units (SKUs) of diverse types of products. Goods from multiple SKUs are replenished into containers and stocked within the distribution center with a goal to maximize storage and picking efficiency.

A distribution center may have a regular inflow of SKUs containing goods of different types, sizes, manufacturers, and the like. These goods may need to be replenished into containers (such as totes) for stocking within the distribution center, and/or for further handling, (such as sorting, shipping, etc.) in a material handling environment. Thus, an operator may need to identify an appropriate container based on size, type, etc. of the goods in an SKU for replenishment. This process is generally time consuming and inefficient. Automating the replenishment process can reduce time, manpower, and costs.

The methods and systems for replenishing containers with goods from SKUs arriving at a replenishment area in a distribution center, described herein in accordance with one or more embodiments of the present disclosure, automatically identify the right container(s) for storing goods from each SKU, delivery the identified container(s) to the operator for replenishment, and return the container(s) to storage and/or to further handling stations.

FIG. 1 illustrates a perspective view of a distribution center (DC) 100, in accordance with one or more embodiments of the present disclosure. The DC 100 may receive goods in bulk from various manufacturers, suppliers, stores, shipping stations, and the like, and may store and/or handle received goods until the goods are further picked and/or shipped. The received goods may be transferred into totes and/or containers of appropriate size, shape, material, etc. for storage and/or further processing. In accordance with the present disclosure, the DC 100 may have a replenishment area 105 for replenishing one or more containers 110 with goods arriving at the replenishment area 105 in multiple stock keeping units (SKUs) 115. The term “replenishment area” as used herein may refer to an area, system, workstation, and the like in the DC 100 for transferring goods from the multiple SKUs 115 into one or more containers 110. The replenishment area 105 may have a collaborative system of multiple material handling devices and systems, such as, but not limited to, infeed conveyors, outfeed conveyors, goods to operator workstations, devices, staging units, and the like. Transferring goods from an SKU into the containers 110 may be automated, for example, may be done by a robotic tool, and/or may be a manual process carried out by an operator, such as operator 125, as shown in FIG. 1

Further, an SKU 115 may include goods of a similar type, size, shape, and/or any other common characteristic. Each SKU 115 may have a corresponding SKU identifier (not shown) associated with the SKU 115. SKU identifier is an unique identifier that may be used to identify a particular SKU 115, such as, but not limited to, a barcode label, RFID tag, etc. The SKU identifier is associated with information related the SKU 115, such as, item number, number of goods in the SKU, type of goods, manufacturer or supplier details, SKU size, SKU weight, and the like. In an embodiment of the present disclosure, the SKU identifier is associated with a first predefined threshold value of a SKU 115. The first predefined threshold value may indicate a maximum capacity of goods contained in the SKU 115. For example, the first predefined threshold value may indicate a cubic measure of the goods contained in the SKU 115. In some embodiments, the SKU identifier may be scanned and/or read at the replenishment area 105 to obtain the information coded in the SKU identifier, such as the first predefined threshold value. In some embodiments, information related the SKU 115 is stored in a database and identifiable based on the SKU identifier.

In an embodiment, one or more SKUs 115 may be grouped together and stacked on a pallet 120, as shown in FIG. 1. The SKUs 115 may be grouped based on a common characteristic, such as type of goods. Additionally or alternatively, mixed SKUs 115 may be grouped randomly and placed on the pallet 120. Further, the SKUs 115 may be grouped and stacked on the pallet 120 by the manufacturer and/or the supplier of the SKUs 115, and/or the SKUs 115 may be grouped and stacked on the pallet 120 at the DC 100 for ease of handling. In an embodiment of the present disclosure, each pallet 120 may further include a pallet identifier (not shown). Pallet identifier may refer to a unique identifier that may be used to identify a particular pallet 120, such as, but not limited to, a barcode label, RFID tag, etc. The pallet identifier may include pallet manifest information identifying number of SKUs on the pallet 120, SKU identifiers of SKUs on the pallet 120, type of goods, manufacturer or supplier details, pallet size, pallet weight, and the like. In an embodiment of the present disclosure, the pallet identifier may include first predefined threshold values for each SKU 115 placed on the pallet 120. Thus, the pallet identifier may indicate a maximum capacity of goods contained in each individual SKU 115 placed on the pallet 120. In another embodiment, the pallet identifier may indicate a collective maximum capacity of goods placed on the pallet 120 by determining a sum of first predefined threshold values for each SKU 115 placed on the pallet 120. The pallet identifier may be scanned and/or read at the replenishment area 105 to obtain the information coded in the pallet identifier. In some embodiments, information related the pallet 120 is stored in a database and identifiable based on the pallet identifier. In some embodiments, by scanning pallet identifier at the replenishment area 105, the information related the pallet 120 is updated to indicate that location of the pallet 120 is at the replenishment area 105.

In accordance with the present disclosure, with reference to FIG. 1, the replenishment area 105 further includes a gravity flow rack 130 for staging and/or conveying one or more containers 110. In the disclosed embodiment, the replenishment area 105 may include a first replenishment zone 135 having a first set of containers 145 and a second replenishment zone 140 having a second set of containers 150, as shown in FIG. 1. The two replenishment zones will be described later with reference to FIG. 2 and FIG. 3. The gravity flow rack 130 may be placed between the first replenishment zone 135 and the second replenishment zone 140, such that the gravity flow rack 130 may convey replenished containers 110 from the first replenishment zone 135 to the second replenishment zone 140, and convey empty containers 110 back from the second replenishment zone 140 to the first replenishment zone 135. The gravity flow rack 130 may also function as a staging area for the empty and/or filled containers 110 until the containers 110 are handled by the operator 125 and/or a robotic tool.

The replenishment area 105 may further include one or more devices 155, as shown in FIG. 1. The devices 155 may refer to any portable and/or fixed device communicably coupled to a central controller (not shown) for assisting the operator 125 in the replenishment process. The device 155 may include, but is not limited to, scanners, imagers, displays, computers, communication devices, headsets, and the like. In an embodiment, one or more devices 155 may scan the SKU identifiers and/or the pallet identifiers to obtain a first set of data including the first predefined threshold values for each SKU 115 arriving at the replenishment area 105. The one or more devices 155 may transmit the first set of data to the central controller for further processing. The one or more devices 155 may further receive data, commands, workflows, etc. from the central controller and/or any other device communicably coupled to the one or more devices 155.

Thus, in accordance with an embodiment of the present disclosure, pallets 120 having one or more SKUs 115 may arrive at the replenishment area 105 of the DC 100. The operator 125 may scan the pallet identifier and/or each SKU identifier using the device 155. The device 155 may obtain the first set of data from the pallet identifier and/or SKU identifiers, and may transmit the first set of data to the central controller. The central controller may identify one or more containers 110 for replenishing goods from an SKU 115 and/or the pallet 120 based on the first set of data, as will be described later with reference to FIGS. 2 and 3. The operator 125 or a robotic tool may pick the identified one or more containers 110 from the first set of containers 145 on the gravity flow rack 130 for replenishing the one or more containers 110 with the goods in the SKU 115 and/or the pallet 120. Once replenished, the one or more containers 110 may be placed on the gravity flow rack 130 and may be conveyed from the first replenishment zone 135 to the second replenishment zone 140 through the gravity flow rack 130. Further, an operator or a robotic tool in the second replenishment zone 140 may replenish a second set of containers 150 with goods in the one or more containers 110 on the gravity flow rack 130 received from the first replenishment zone 135. Empty container(s) are placed on the gravity flow rack 130 for transferring back to the first replenishment zone 135 for receiving goods from a next SKU 115 and/or pallet 120.

In some embodiments of the present invention, a controller (such as the central controller described below) determines the best pallet to choose for replenishment. For example, the controller may receive a priority table that indicates the priorities for replenishing the pallets. Based on the priority table, the controller may determine the pallet for replenishment. In some embodiments, the controller may retrieve a special rule based on the particular material handling environment that the replenishment took place.

In an embodiment, the second set of containers 150 may include shuttle totes for storing goods in an Automated Storage and Retrieval System (ASRS) in the DC 100. Once filled, the second set of containers 150 may be pushed onto a take away conveyor 160, as shown in FIG. 1. The take away conveyor 160 may convey the replenished second set of containers 150 to a storage location and/or to downstream material handling systems for further processing and/or handling.

FIG. 2 illustrates a perspective view of the first replenishment zone 135 of the distribution center (DC) 100, in accordance with one or more embodiments of the present disclosure. The replenishment process in the first replenishment zone 135 includes replenishing one or more containers 110 from the first set of containers 145 placed on the gravity flow rack 130 with goods from the one or more SKUs 115 arriving at the replenishment area 105. The first set of containers 145 may include containers 110 of different types, size, shape, and the like. In an embodiment, as shown in FIG. 2, the first set of containers 145 includes containers of three different sizes: 145a, 145b, 145c. Containers 145a may be moderate size containers, whereas containers 145b may be smaller than containers 145a, and containers 145c may be larger than containers 145a. Further, each of the containers 110 has an associated container identifier (not shown). As described above, the container identifier may refer to a unique identifier that may be used to identify a particular container of containers 110, such as, but not limited to, a serial number, a barcode label, RFID tag, etc. The container identifier may include information regarding the container 110, such as, but not limited to, type, size, capacity, weight, shape, and the like.

In an embodiment of the present disclosure, each container identifier may include a second predefined threshold value for a corresponding container of containers 110. The second predefined threshold value may indicate a capacity of the container. In an embodiment, the second predefined threshold value may indicate a maximum capacity of the container. For example, the second predefined threshold values for each of the three containers 145a, 145b, and 145c may be x cubic unit, y cubic unit, and z cubic unit, such that x>y and y<z. In another embodiment, the second predefined threshold value may indicate a current capacity of the container, for example, when the container is partially occupied. The container identifier for a container may be scanned before each replenishment operation for the container so that the central controller and/or any other device in the DC 100 may track occupied volume of the container 110, and thus, may calculate a current capacity based on the maximum capacity of the container 110 and the occupied volume.

For maximizing the storage capacity and overall efficiency of the DC 100, it is important to pick appropriate sized container(s) 110 from the first set of containers 145 for storing goods from the SKUs 115. For example, an SKU 115 may have x1 cubic unit of goods, as identified by the first predefined threshold value associated with the SKU 115, as described above. For example, x1 cubic unit may equal to the sum of x and y cubic units corresponding to containers 145a and 145b. However, if an operator 125 selects the containers 110 for replenishment based on visual inspection of the goods in an SKU and the containers 145, the operator 125 may not select the most appropriate and optimal container(s) 110 from the first set of containers 145.

Thus, in accordance with the present disclosure, the containers are identified based on the first predefined threshold value and the second predefined threshold value by the central controller. That is, the operator 125 scans a SKU identifier associated with an SKU 115 being handled or a pallet identifier associated with the pallet that SKU 115 is on. In response, the central controller receives a first set of data having a first predefined threshold value of the SKU 115. The first predefined threshold value indicates the maximum capacity of goods in the SKU 115, for example, x1 cubic unit, as described above.

The central controller may then access a database of a second set of data. The second set of data may refer to data associated with the one or more containers 110 in the replenishment area 105. In an embodiment, the second set of data may include container identifiers, such as serial numbers, for each container 110 being used in the replenishment process. The container identifiers may further include the second predefined threshold values for each container 110, indicative of a capacity of the container 110, for example x cubic unit for container 145a. The central controller correlates the first predefined threshold value of the SKU 115 with the second predefined threshold values for the containers 110. Thus, the central controller may determine that the operator 125 may need one of each containers 145a and 145b having x and y cubic unit capacity to accommodate goods from the SKU 115 having x1 cubic unit of goods, wherein x1 equals to the sum of x and y cubic units.

Further, the central controller may generate a first ordered sequence of container identifiers based on the above determination. For example, the central controller may generate an ordered sequence of a serial number of a container 145a followed by a serial number of a container 145b for the SKU 115. The ordered sequence of container identifiers may be transmitted to the replenishment area 105 and may be displayed on a display of device 155, as shown in FIG. 2. The operator 125 may follow the ordered sequence displayed on the display of device 155, and may pick the identified containers 145a and 145b from the gravity flow rack 130 for replenishing with goods from the SKU 115. In an embodiment, the identified containers 145a and 145b may be presented to the operator 125 in the ordered sequence, for example, on a goods-to-operator workstation. In another embodiment, the gravity flow rack 130 may include a pick-to-light system such that pick-to-light system displays an ordered sequence of indicators (such as light) at the locations of the identified containers 145a and 145b corresponding to the first ordered sequence of container identifiers.

Further, the operator 125 or a robotic tool may verify container identifiers associated with each picked container (145a and 145b, for example) by scanning the container identifier (such as a barcode label) placed on the container. The central controller and/or a device 155 at the replenishment area 105 may verify that the operator 125 or the robotic tool has picked the right containers by matching the container identifier from the barcode label to the container identifier information stored in a database associated with the central controller and/or the device 155.

Further, the central controller and/or the device 155 may further marry and/or associate the container identifiers of the containers 145a and 145b to the SKU 115 for goods tracking purposes. For example, subsequent to replenishing the goods from a SKU to a container, the central controller and/or the device 155 may associate the container identifier with the SKU identifier so that the central controller and/or the device 155 can track, in real time, goods in the container.

After picking the containers 145a and 145b from the gravity flow rack 130 and replenishing the containers 145a and 145b with goods from the SKU 115, the operator 125 or a robotic tool may then place the replenished containers 145a and 145b on the gravity flow rack 130 for transferring the filled or partially filled containers 145a and 145b to the second replenishment zone 140, as will be described with reference to FIG. 3. In an embodiment, partially filled containers 145 may be retained on the gravity flow rack 130 for further indication of association to a next SKU 115. In this regard, the central controller may determine a related SKU to the SKU 115 which was destocked into the container 110 by matching one or more characteristics of the SKUs, such as, but not limited to, type of goods, batch of goods, and the like. The central controller may then assign the container identifier of the partially filled container 110 to the one or more related SKUs based on the second predefined threshold value of the container. Thus, the storage capacity of the container 110 may be fully utilized.

The gravity flow rack 130, in accordance with the present disclosure, includes a multilevel staging area 205 for containers 110. The multilevel staging area 205 includes a plurality of conveying sections 210. In an embodiment, each conveying section 210 may have strip belts 215 for conveying containers 110 between the first replenishment zone 135 and the second replenishment zone 140. In another embodiment, the conveying sections 210 may be inclined towards the second replenishment zone 140, such that replenished containers 145a and 145b may be pushed on the conveying sections 210 by the operator 125 or a robotic tool, and the containers 145a and 145b may be conveyed to the second replenishment zone 140 because of gravity. In an embodiment, the conveying sections 210 may have a combination of the strip belts 215 and the incline. The gravity flow rack 130 may further include a central gravity conveyor section 220, as shown in FIG. 2. The central gravity conveyor section 220 may be inclined towards the first replenishment zone 135, such that empty containers 110 may be transferred from the second replenishment zone 140 to the first replenishment zone 135 on the central gravity conveyor section 220, as will be described with reference to FIG. 3.

FIG. 3 illustrates a perspective view of the second replenishment zone 140 of the distribution center (DC) 100, in accordance with one or more embodiments of the present disclosure. The replenishment process in the second replenishment zone 140 includes replenishing one or more containers from the second set of containers 150 with goods from the replenished first set of containers 145 arriving at the second replenishment zone 140 through the gravity flow rack 130. In accordance with the present disclosure, the central controller may further generate a second ordered sequence of container identifiers indicative of an ordered sequence of the second set of containers 150 to be replenished with the goods from the first set of containers 145. In an embodiment, the second set of containers 150 may be shuttle totes having multiple compartments of different size. The shuttle totes may be partially filled or empty, and may be used to store goods in a storage facility, such as an ASRS system, in the DC 100. Various embodiments of the present invention maximize and optimize the storage capacity of shuttle totes so that a shuttle tote may be sent to the ASRS only when the shuttle tote is completely filled. This reduces the time and resources spent in transferring half-filled shuttle totes to the storage location and retrieving the half-filled shuttle totes for further replenishment.

The second set of data accessible to the central controller may further include container identifiers for the second set of containers 150. As described above, the container identifiers for the second set of containers 150 may include a third predefined threshold value for each of the second set of containers 150. The third predefined threshold value may be indicative of a capacity of each of the second set of containers 150. In an embodiment, the third predefined threshold value may indicate a maximum capacity of each of the second set of containers 150. In another embodiment, the third predefined threshold value may indicate a current capacity of each of the second set of containers 150. The central controller may correlate the third predefined threshold values of the second set of containers 150, for example, shuttle totes, to the second predefined threshold values of the one or more first set of containers 145 that are replenished and have arrived at the second replenishment zone 140. Based on the correlation, the central controller may generate a second ordered sequence of container identifiers for the second set of containers 150. In response, the second set of containers 150 may be queued according to the ordered sequence of container identifiers, as shown in FIG. 3. The operator 125 or a robotic tool may replenish one or more containers from the second set of containers 150 available for replenishment with goods from the first set of containers 145 based on the second ordered sequence of container identifiers. For example, the central controller may provide a visual and/or an audio indication to the operator 125 identifying container identifiers for one or more of the first set of containers 145 to be picked for replenishing the container from the second set of containers 150 available for replenishment. In an embodiment, the central controller may further indicate one or more compartments in the second set of containers 150 to be replenished with goods from the one or more of the first set of containers 145.

Further, as described above, the operator 125 may scan container identifiers associated with each of the first set of containers 145 picked by the operator 125 and a container identifier, such as a barcode label, associated with the container from the second set of containers 150 available for replenishment. The central controller and/or a device 155 at the replenishment area 105 may verify that the operator 125 has picked the right containers by matching the container identifiers from the barcode label to the container identifier stored in a database associated with the central controller and/or the device 155. Further, the central controller and/or the device 155 may further marry and/or associate the container identifiers of the one or more containers from the second set of containers 150 receiving goods from the SKU 115 via one or more first set of containers 145, for goods tracking purposes.

For example, the central controller may maintain a log of flow of goods from the SKU 115 to the one or more first set of containers 145. When the goods are transferred from the one or more first set of containers 145 to one or more second set of containers 150, the log may be updated to associate the SKU 115 identifier with the container identifier(s) of the one or more second set of containers 150. After the goods are transferred, the one or more first set of containers 145 may be disassociated from the SKU 115 by the central controller and may be available to be associated with a next SKU by the central controller. Thus, the goods are tracked within the DC 100 throughout the replenishment process.

In some embodiments, the operator 125 or a robotic tool may scan the container identifier corresponding to one of the second set of containers (i.e. shuttle totes) and the container identifier(s) corresponding to one or more first set of containers based on the second ordered sequence of container identifiers. This enables the central controller to determine any error condition that may have occurred, such as, for example, the shuttle tote is not empty, the shuttle tote size does not fit the goods to be replenished, etc. The error condition can be dynamic and configurable, and may change and adapt as needs require.

As mentioned above, after replenishment, the operator 125 may place the empty containers from the first set of containers 145 on the central gravity conveyor section 220. The central gravity conveyor section 220 may be inclined towards the first replenishment zone 135, such that empty containers 110 may be transferred from the second replenishment zone 140 to the first replenishment zone 135 to receive goods from a next SKU 115. Further, when a container 110 from the second set of containers 150 is replenished with goods from the one or more first set of containers 145, the operator 125 or a robotic tool may push the container 110 onto the take away conveyor 160, as shown in FIG. 3. The take away conveyor 160 may convey the container 110 to a storage location and/or to downstream material handling systems for further processing and/or handling.

Thus, the replenishment process is automated and optimized by automatically identifying appropriate containers from a wide variety of containers available for replenishment, and presenting the containers in an ordered sequence to an operator or a robotic tool for replenishment.

FIG. 5 illustrates an example method 500 for replenishing containers 110 with goods from stock keeping units (SKUs) 115, in accordance with one or more embodiments of the present disclosure. The method 500 may include receiving, by the central controller 415 and/or any other associated device, a first set of data associated with a plurality of SKUs 115 arriving at the replenishment area 105, at block 505. The first set of data may include a plurality of first predefined threshold values, each indicative of a maximum capacity of goods in a corresponding SKU 115. As described above, in an embodiment, the first set of data may be obtained by scanning and/or reading, by a device 155, SKU identifiers associated with each of the plurality of SKUs 115. SKU identifier may refer to a unique identifier that may be used to identify a particular SKU 115, such as, but not limited to, a barcode label, RFID tag, etc. The device 155 may be communicably coupled to the central controller 415, and may transmit the first set of data to the central controller 415. Based on the received first set of data, the central controller 415 may determine first predefined threshold values for each of the plurality of SKUs 115. The first predefined threshold values may indicate a maximum capacity of goods contained in each SKU 115. For example, the first predefined threshold value may indicate a cubic measure of the goods contained in the SKU 115.

The method 500 may further include associating the first set of data to a second set of data having one or more container identifiers with each container identifier having a second predefined threshold value, at block 510. As described above, each container 110 may have an associated container identifier. The container identifier may refer to a unique identifier that may be used to identify a particular container 110, such as, but not limited to, a serial number, a barcode label, RFID tag, etc. The container identifier may include information regarding the container 110, such as, but not limited to, type, size, capacity, weight, shape, and the like. In an embodiment of the present disclosure, each container identifier may include a second predefined threshold value for a corresponding container 110. Further, each second predefined threshold value may be indicative of a capacity of a corresponding container 110. For example, the second predefined threshold value may indicate a current and/or a maximum capacity of the container 110. In an embodiment, the central controller 415 may receive the second set of data from the memory 425 and/or from a remote database accessible to the central controller 415. The central controller 415 may associate the first set of data to the second set of data by correlating the first predefined threshold values to the second predefined threshold values. For example, the central controller 415 may determine that the first predefined threshold value indicative of a maximum capacity of goods associated with an SKU 115 is X cubic unit. The central controller 415 may access a database of second set of data to match and/or correlate the first predefined threshold value of X cubic unit to one or more second predefined threshold values associated with one or more container identifiers in the second set of data. For example, the central controller 415 may search for a container identifier having second predefined threshold value equal to or slightly more than X cubic unit. In an embodiment, if there are no container identifier having second predefined threshold value equal to or slightly more than the first predefined threshold value, the central controller 415 may correlate the first predefined threshold value to multiple container identifiers such that the sum of the second predefined threshold values of the one or more containers is more than or equal to the first predefined threshold value.

The method 500 may further include generating an ordered sequence of container identifiers based on the association of the first set of data with the second set of data, at block 515. For example, in accordance with the present disclosure, the ordered sequence of container identifiers may be indicative of the containers to be retrieved to the replenishment area 105 for receiving goods from the plurality of SKUs 115. Based on the association described above, the central controller 415 may identify one or more containers corresponding to the one or more container identifiers associated with the first predefined threshold value by the central controller 415. For example, the central controller 415 may determine that two containers having x and y cubic unit capacity should be replenished with the goods from the SKU 115 having a=x+y cubic unit of goods. Based on the determination, the central controller 415 may generate an ordered sequence of container identifiers indicative of the containers to be retrieved to the replenishment area 105 for receiving goods from the SKU 115. For example, the central controller may generate an ordered sequence indicating a container with x cubic unit capacity followed by a container with y cubic unit capacity should be used to replenish goods from an SKU 115 having a=x+y cubic unit of goods.

In some embodiments, the central controller 415 may transmit the ordered sequence of container identifiers to the replenishment area 105, for example, by displaying the ordered sequence on a display of device 155. The operator 125 may follow the ordered sequence displayed on the display of device 155 and may pick the identified containers 110 for replenishing with goods from an SKU 115. In some embodiments, the central controller 415 may transmit the ordered sequence of container identifiers to a container presenting means, such as a goods-to-operator workstation, for presenting the identified containers 110 to the operator 125 and/or a robotic tool in the ordered sequence. Thus, the operator 125 and/or a robotic tool may replenish identified containers with goods from one or more SKUs 115 arriving at the replenishment area 105.

In some embodiments, the central controller 415 may determine one or more related SKUs from the plurality of SKUs based on matching at least one characteristic of the plurality of SKUs. For example, the central controller 415 may determine that two SKUs have the same size. Based on the matching of at least one characteristic, the central controller 415 may assign the same container identifier to the one or more related SKUs to indicate that they have the same second predefined threshold value.

FIG. 6 illustrates an example method 600 for replenishing containers 110 with goods from stock keeping units (SKUs) 115, in accordance with one or more embodiments of the present disclosure. The method 600 relates to generating an ordered sequence of container identifiers for a plurality of SKUs 115 arriving at the replenishment area 105. The method 600 includes determining a first predefined threshold value for an SKU 115, at block 605. As described above, the central controller 415 and/or any other associated device may receive a first set of data having a first predefined threshold value for the SKU 115, for example, from a device 155 reading and/or scanning a SKU identifier associated with the SKU 115 at the replenishment area 105. The first predefined threshold value may be indicative of a maximum capacity of goods in the corresponding SKU 115. Further, the method 600 includes identifying one or more containers 110 such that a sum of the second predefined threshold values of the one or more containers 110 is more than or equal to the first predefined threshold value of the SKU 115, at block 610. As described above, each container 110 may have an associated container identifier. The container identifier may refer to a unique identifier that may be used to identify a particular container 110, such as, but not limited to, a serial number, a barcode label, RFID tag, etc. Each container identifier may include a second predefined threshold value for a corresponding container 110. Further, each second predefined threshold value may be indicative of a capacity of a corresponding container 110. For example, the second predefined threshold value may indicate a current and/or a maximum capacity of the container 110. Thus, the central controller 415 may identify one or more containers 110 such that a sum of the second predefined threshold values of the one or more containers 110 is more than or equal to the first predefined threshold value of the SKU 115. The method 600 further includes determining container identifiers associated with each of the one or more containers 110 as an ordered sequence of containers for the SKU 115, at block 615. For example, the central controller 415 may generate an ordered sequence of container identifiers having a segment indicating Container A, followed by Container B, followed by Container C for the SKU 115.

At block 620, the method 600 determines whether there are any SKUs 115 that has not been handled. If so, the method 600 proceeds to block 605 and repeats the above steps for each SKU 115. Thus, the overall ordered sequence of container identifiers for a plurality of SKUs 115 may be a combination of determined ordered sequence corresponding to each SKU 115. For example, the overall ordered sequence for the plurality of SKUs 115 may include Container A, followed by Container B, followed by Container C, followed by Container X, . . . , followed by Container Z. Further, if there are no more SKUs 115 for handling at block 620, the method 600 proceeds to block 625 and ends.
