The present application is a continuation of U.S. patent application Ser. No. 16/733,821, filed on Jan. 27, 2020 and entitled MULTI-LINE SYSTEM AND METHOD FOR RETRIEVING AND FULFILLING ITEMS IN A CUSTOMER ORDER, which is a continuation-in-part patent application of U.S. patent application Ser. No. 16/727,676, filed on Dec. 26, 2019 and entitled SYSTEM AND METHOD FOR PERFORMING BULK PICK OF ITEMS OF A CUSTOMER ORDER, which in turn is a continuation-in-part patent application of U.S. patent application Ser. No. 16/514,897, entitled SYSTEM AND METHOD FOR PERFORMING BULK PICK OF ITEMS OF A CUSTOMER ORDER, filed on Jul. 17, 2019, which claims priority to provisional patent application Ser. No. 62/700,619, filed on Jul. 19, 2018, and entitled SYSTEM AND METHOD FOR PERFORMING BULK PICK OF ITEMS OF A CUSTOMER ORDER. The contents of all of the foregoing are incorporated herein by reference.
BACKGROUND OF THE INVENTIONVendors, particularly in home shopping industries involving telephone ordering, mail ordering, or e-commerce, often need to fulfill and package customer orders to be shipped to customers. The customer order may include one or more product items, as well as promotional literature. In some circumstances, product fulfillment and packaging may be done manually with a worker picking items corresponding to the customer order from a fulfillment center or warehouse and then inserting orders into packages. In order to increase efficiency over conventional manual picking and packaging techniques, automated picking stations and packing machines have been introduced. However, such picking processes are designed to have a person simply pick an item from a selected location and then transfer the item to a packing station for packaging, without regard to optimizing the pick route or picking and packaging process.
Further, conventional item picking and packaging systems require large capital investments, and still are not fully adapted to optimize the item picking and packaging process.
SUMMARY OF THE INVENTIONThe present invention is directed to an order fulfillment system that receives and processes customer orders, and then determines whether the specific items in the collected customer orders warrant the creation and execution of a bulk pick or a pick tour to be executed by a pick agent. If the system determines that a series of pick tours are required, the pick tour subsystem receives information from the order collection unit, determines the location of the items in the warehouse based on a warehouse map, instructs the pick agent how to manage or setup a mobile pick cart, generates a value sorted tree map, and then generates a pick tour plan. The pick tour plan is then converted into a pick tour to be performed by the pick tour agent. In the pick tour, the location of the items in the warehouse are proved to the pick agent and the pick tour agent is instructed to select the items at specific locations in a predefined sequence.
The customer order fulfillment system of the present invention includes an order collection unit for collecting information associated with a plurality of customer orders from a plurality of customers and generating customer order data that includes data associated with each of the plurality of customer orders and the plurality of customers, wherein each of the plurality of customer order includes one or more items associated therewith; an order generating unit for receiving the customer order data from the order collection unit and generating in response thereto consolidated order fulfillment data; and a pick tour generating subsystem for receiving the consolidated order fulfillment data from the order generating unit and in response thereto generating pick instructions associated with a pick tour plan or a pick tour from the consolidated order fulfillment data. Further, the order fulfillment system includes a bulk pick order fulfillment unit for receiving the consolidated order fulfillment data from the order generating unit and grouping together similar ones of the items associated with the plurality of customer orders to form a plurality of bulk picks, wherein one or more of the plurality of bulk picks can form part of one or more bulk pick tours, and an automated fulfillment system for receiving the consolidated order fulfillment data from the order generating unit and for automatically selecting one or more of the items in the customer order from one or more carousels. The automated fulfillment system is configured for receiving the pick tour plan or the pick tour and for automatically selecting the items in the customer order set forth in the pick tour plan or the pick tour from the one or more carousels, and/or is configured for receiving one or more of the plurality of bulk picks for automatically selecting one or more of the items in the customer order from the one or more carousels.
The pick tour generating subsystem comprises a map unit for storing a map having map data associated therewith that corresponds to a location for each of the items in a warehouse; a cart building unit for generating information associated with a mobile cart for use by a pick agent, wherein the mobile cart has a plurality of totes associated therewith and wherein each of the plurality of totes includes identification information; a graph generating unit for generating a value sorted tree graph by employing a value sorted tree mapping technique based on the map data and the consolidated order fulfillment data, and wherein the value sorted tree graph includes data associating one or more of the items from the plurality of customer orders with a selected location in the warehouse; and a pick tour generator for generating a pick tour plan based on the value ordered tree graph and the map data, wherein the pick tour plan correlates items of the customer orders at multiple selected locations in the warehouse with one or more of the plurality of totes in the mobile cart. The cart building unit determines the number of the totes for the mobile cart and the identification information associated with each of the plurality of totes based on the pick tour plan.
According to another aspect of the invention, one or more of the plurality of totes includes a plurality of sub-compartments where each of the plurality of sub-compartments includes identification information. The totes can be arranged on the mobile cart according to the requirements of the pick tour plan and optionally according to the sequence of the locations of the items in the warehouse.
According to another aspect of the invention, the value sorted tree graph is an associative array data type having values associated therewith, wherein the value sorted tree graph sorts the values in a selected order. The values correspond to the locations in the warehouse or to a number of the items at the locations in the warehouse. Further, the locations within the warehouse include one or more bays associated with each location in the warehouse, and the pick tour plan comprises plan data correlating the location of the bay with selected ones of the items at the locations of the bays to be placed in specific totes in the mobile cart.
According to still another aspect of the invention, the pick tour plan is generated by the pick tour generator by mapping the consolidated order fulfillment data generated by the order generating unit with the warehouse configuration stored in the map unit via the graph generating unit. The pick tour generator converts the pick tour plan into a pick tour that sets forth an ordered list of pick tasks. Further, each of the pick tasks includes a selected one of the following: the location of the bay, identification information associated with the location of the bay, shipping information associated with one or more of the customer orders, a quantity of the items, identification information associated with each of the items, one or more of the items to be picked from the bay, and the tote on the mobile cart in which to place the picked items. The pick tour generator generates the pick tour based on a similarity in the customer orders and the location of the items in the warehouse.
According to yet another aspect of the invention, the system further includes a bulk pick order fulfillment unit for receiving the consolidated order fulfillment data from the order generating unit and grouping together similar ones of the items associated with the plurality of customer orders to form a plurality of bulk picks, wherein one or more of the plurality of bulk picks can form part of one or more bulk pick tours, The bulk pick order fulfillment unit groups the items in the consolidated order fulfillment data into shipments according to one or more predetermined logical parameters. Still further, the bulk pick order fulfillment unit includes processing hardware that is configured to map the one or more items in each of the plurality of customer orders to product identification data, generate one or more bulk picks having associated therewith one or more bulk pick recipes from the data associated with the customer orders, wherein each of the bulk pick recipes includes a selected quantity of the one or more items from the plurality of customer orders and a selected quantity of one or more additional items, and generate a bulk pick ticket associated with each of the bulk picks.
The bulk pick ticket includes information about the one or more items in the bulk pick recipe, and location information associated with the location of the one or more items in the warehouse. The bulk pick order fulfillment unit generates a connected graph of groupings of the items from the customer orders and the one or more additional items, wherein the items from the customer orders and the additional items form nodes of the connected graph.
According to another aspect of the invention, the system can also include a packing and shipping sub-system for packing and shipping the items from the customer orders, as well as a controller for scheduling one or more selected time periods for performing the bulk pick tour or the pick tour.
The present invention is also directed to a method for retrieving items from a customer order from a warehouse so as to fulfill a customer order, comprising collecting information associated with a plurality of customer orders from a plurality of customers and generating customer order data that includes data associated with each of the plurality of customer orders and the plurality of customers, wherein each of the plurality of customer order includes one or more items associated therewith; generating in response to the customer order data consolidated order fulfillment data; and receiving the consolidated order fulfillment data and generating pick tour instructions associated with a pick tour from the consolidated order fulfillment data by a pick tour generating subsystem.
The method also includes receiving the consolidated order fulfillment data from the order generating unit and grouping together similar ones of the items associated with the plurality of customer orders to form a plurality of bulk picks with the bulk pick order fulfillment unit , wherein one or more of the plurality of bulk picks can form part of one or more bulk pick tours, and receiving the consolidated order fulfillment data from the order generating unit and for automatically selecting one or more of the items in the customer order from one or more carousels with the automated fulfillment system. The automated fulfillment system is configured for receiving the pick tour plan or the pick tour and for automatically selecting the items in the customer order set forth in the pick tour plan or the pick tour from the one or more carousels, and is configured for receiving one or more of the plurality of bulk picks for automatically selecting one or more of the items in the customer order from the one or more carousels.
According to another aspect of the invention, the method includes generating the pick tour plan by mapping the consolidated order fulfillment data generated by the order generating unit with the warehouse configuration stored in the map unit via the graph generating unit. The method can also include converting with the pick tour generator the pick tour plan into a pick tour that sets forth an ordered list of pick tasks.
According to still another aspect of the invention, the method also includes a bulk pick order fulfillment unit for receiving the consolidated order fulfillment data from the order generating unit and grouping together similar ones of the items associated with the plurality of customer orders to form a plurality of bulk picks, wherein one or more of the plurality of bulk picks can form part of one or more bulk pick tours. The method can also include grouping the items in the consolidated order fulfillment data into shipments according to one or more predetermined logical parameters.
These and other features and advantages of the present invention will be more fully understood by reference to the following detailed description in conjunction with the attached drawings in which like reference numerals refer to like elements throughout the different views. The drawings illustrate principals of the invention and, although not to scale, show relative dimensions.
Exemplary embodiments of the present invention address these and other problems associated with the picking of items corresponding to a customer order by employing an order fulfillment system for picking the items and then packaging and shipping the items to the customer.
The present invention is directed to a time based customer ordering and customer order consolidation system suitable for use in an automated or partially automated order fulfillment environment. The customer order can include one or more items that the customer has selected or purchased, and can if desired include additional items, such as warranty information, sales or promotional literature and related brochures, item instructions and the like.
As shown in
The order generating unit 14 can be monitored by a separate computing system and/or a warehouse supervisor via the computing system to determine the order fulfillment actions that need to be taken. The order generating unit 14 is adapted or configured to prepare a set of order fulfillment instructions or data for fulfilling the incoming customer orders in a time based manner. The fulfillment order instructions can be based on a set of logical rules and ordering priorities for releasing one or more customer orders to be fulfilled by the order fulfillment system 10.
The consolidated order fulfillment instructions or data generated by the order generating unit 14 can be transmitted to an automated fulfillment system 16, such as an automated product picking system, as shown for example in
Alternatively, the order generating unit 14 can transmit the order fulfillment instructions to a bulk pick order fulfillment unit 18. For example, according to one practice, the order generating unit 14 can be configured to group together a set of customer orders that share similar features, items or traits, into a larger bulk pick order, and the bulk pick order data can be transmitted to the bulk pick order fulfillment unit 18. Alternatively, the bulk pick order fulfillment unit 18 can generate the bulk pick data. The bulk pick orders (e.g., a bulk pick order wave) are groupings of customer orders that may be picked or fulfilled in a warehouse in aggregate as opposed to fulfilling each customer order independently. As such, warehouse data can include the configuration of the warehouse, which can include for example rows of storage racks with associated storage bins, and data associated with specific items located in specific bins at specific warehouse locations, can be stored in the database 24 or elsewhere in the system 10 and is accessible by the order generating unit 14, the bulk pick order fulfillment unit 18 and the pick tour generating unit 20. The bulk pick orders forming the bulk pick wave are selected so as to optimize the fulfillment process by selecting orders that have certain features, items or traits in common. The bulk pick order fulfillment unit 18 can generate data associated with a bulk pick that can form part of a bulk pick tour or wave, and which can be fulfilled by the automated product picking system 16, by one or more mobile operators or pick agents that manually pick one or more items corresponding to the bulk pick tour, or by both. As used herein, the term “bulk pick,” “bulk pick tour,” or “bulk pick wave,” is intended to mean a plurality of similar or identical items that are grouped or bulked together and which can be selected based on the warehouse data from a selected warehouse location. The bulk picks or grouped items when assigned to the automated fulfillment system and/or to a pick tour agent for retrieval form the bulk pick tours. The bulk picks or bulk pick tours can then be assigned to the pick agents and/or to the automated fulfillment unit separately, concurrently or in series to form a bulk pick wave.
Additionally or alternatively, the order generating unit 14 can interface with a pick tour generating unit 20, which receives the order fulfillment instructions from the order generating unit 14. The pick tour generating unit 20 can generate pick tour instructions for a single item or a multi-item order. The pick tour instructions can be forwarded to the automated product picking system and/or to a pick tour mobile operator for performing a pick tour. The pick tour generating unit 20 generates pick tour instructions based on the consolidated customer order information received from the order generating unit 14. The pick tour instructions leverage the similarity in customer orders and item locations within the warehouse so as to minimize the amount of time it takes to pick the one or more items that comprise the customer order. The pick tour instructions can generate or be converted into a pick tour that can be assigned to pick agents or mobile operators. The pick agents can utilize a mobile cart that has selected compartments associated therewith to manually pick or select the items that correspond to the customer orders from the warehouse. The pick agent can employ a handheld scanning device, such as for example the conventional handheld scanners sold by Intermec, that can guide the pick agent to the selected location of the item and assist the pick agent in selecting the correct item. The handheld device also serves to allow the order fulfillment system 10 to track and verify the location of the pick agent, and to perform product and location verification in real time. As used herein, the term “pick tour” is intended to mean a series of instruction that include one or more pick tasks that when aggregated or consolidated together form a tour. The tour is in essence a series of instructions sent to the pick agent to pick, select or retrieve one or more items associated with one or more customer orders from selected locations within the warehouse. Alternatively, the pick tour can be performed by the automated fulfillment system 16, which receives the aggregated list of items (or tour) from the pick tour generating unit and retrieves the items from selected locations within the automated fulfillment system.
Once the customer order have been picked and fully assembled, the contents of the order can be assembled into totes or compartments of totes, which are then placed on a conveyor belt and sent to a packing and shipping subsystem 22. A packaging and shipping subsystem suitable for use with the present invention includes the packing station disclosed in U.S. Publ. No. 2014/0360141, to the assignee hereof, the contents of which are herein incorporated by reference. In transit, the order fulfillment system 10 can also include structure for automatically printing a customer invoice and/or packing slips for insertion within the corresponding compartment within the tote. The illustrated packing and shipping subsystem 22 receives the totes and packages the contents of each compartment of the tote for shipping to the customer.
As shown, the illustrated order fulfillment system 10 can also include a general database 24 for storing information concerning the customer orders as well as selected information corresponding to each of the illustrated units and subsystems. Specifically, the database 24 can store customer information, including customer name, address, financial payment details, order history and the like. The database 24 can also store information regarding the items that are stored in the warehouse as well as the warehouse information. The item information can include details of each item, including item type, description, price, quantity and the like. The database can also be configured to store information regarding the programs and associated segments or plays that are broadcast, as well as the sequence of items that are displayed and discussed during the program.
The order generating unit 14 of the present invention is configured to collect data associated with the customer orders and prepare a set of order fulfillment instructions for fulfilling the incoming customer orders in a time based manner. The order fulfillment instructions can be based on a set of logical rules and ordering priorities for releasing one or more customer orders to be fulfilled by the order fulfillment system 10. The order generating unit 14, based on the number of customer orders, and the overlap or similarity between the items in the orders, can send instructions to the bulk pick order fulfillment unit 18 to execute a bulk pick of selected items. The order generating unit 14 or the bulk pick order fulfillment unit 18 can schedule the bulk pick at a time of day that is convenient based on the total number of customer orders being handled, the time of day, the number of pick agents assigned to the warehouse floor, and the like.
The order generating unit 14 can generate a color coded or non-color coded tree map that can be displayed to the supervisors on a suitable display device as a visual representation of the relative amount of work that can potentially be fulfilled via a bulk pick order by the bulk pick order fulfillment unit 18 under a set of configurable operating parameters. An example of such a tree map is shown in
The bulk pick order fulfillment unit 18 employs processing hardware for implementing heuristics and rule based schedules that determine the optimal way to group items in the customer orders into shipments. The logical parameters include consideration of the payment status of the customer or of the customer orders, destination addresses, and services such as sizing and appraisals that may have been applied to the items of the customer order. The bulk pick order fulfillment unit 18 also considers the shipping option selected by the customer and the guaranteed or estimated shipping dates that were communicated to the customer, as well as other factors, including grouping of items based on specific product brand, sales of items, and different sales channels.
Consolidating customer orders into shipments using the foregoing time-based process has multiple benefits and advantages. One advantage is that the process reduces the amount of shipment packaging materials needed, reduces the number of promotional inserts needed, and reduces the overall postage cost of shipping the packages. Additionally, customers may be incentivized to purchase additional items by reduced shipping and handling rates for additional items purchased within a selected time period, such as for example a twenty four hour time period.
The bulk pick order fulfillment unit 18 can also generate one or more bulk pick recipes from the data associated with the connected graph, step 32. As used herein, the term “recipe” or “bulk pick recipe” is intended to mean a collection of selected items from the customer orders and the additional items that are correlated or grouped together. As shown in
When the bulk pick order fulfillment unit 18 generates one or more bulk pick recipes that include ingredients (or the recipe itself) outside of one or more of the predetermined parameters, the unit 18 does not generate a bulk pick employing these recipes. The bulk picks and corresponding bulk pick recipes can be utilized by the system 10, such as by the pick tour generating unit 20 or the automated fulfillment system 16 so that the ingredients within the recipe are selected either by pick agents via a mobile tour or by the automated system. Further, the bulk pick order fulfillment unit 18 partitions or separates the bulk picks from each other according to the bulk pick group count parameter and the maximum item count per bulk pick parameter.
The bulk pick order fulfillment unit 18 then generates a bulk pick sheet or ticket that corresponds to each of the bulk picks 42, 44, 46, step 34. The bulk pick ticket is sent to either a mobile pick agent and/or to the automated fulfillment system 16 to retrieve the items, step 36. If the bulk pick ticket is sent to the automated system 16, processing hardware and corresponding software associated with the system 10 or the automated system 16 can perform the retrieval of the items based on the information contained within the bulk pick ticket.
The items identified by the bulk pick process of the bulk pick order fulfillment unit 18 and as set forth in the bulk pick ticket 80 can be picked according to the following process. One of ordinary skill in the art will readily recognize that the process can include additional steps or can omit one or more of the following steps without departing from the spirit and scope of the present invention.
As shown in
The bulk picking of items in customer orders by the bulk pick order fulfillment unit 18 offers additional benefits and advantages. For example, a bulk pick is more efficient than a shipment pick performed by pick agents in situations where there are many customers that ordered the same set of items. This is because the pick agent only needs to visit a location once per item, and can pick multiple ones of the same item at the same time. Although the pick agent can employ a mobile cart for picking multiple single item shipments, or multiple multi-item shipments on a cart while performing non-bulk picks, a barcode scan is required on each item and tote compartment to perform an association to ensure item movement tracking accuracy. The bulk pick process can handle much larger quantities or items per pick, and does not require a barcode scan.
By way of example, consider a situation where one hundred customers ordered the same item. A pick agent can be directed to pick one hundred of the same item from a stock location and then take the entire group to a bulk processing station where the weight of the item and inserts is acquired once, customer invoices are printed, and then the agent assembles the individual shipments like stuffing envelopes. In addition to single item bulk picks, the system 10 supports multi-item picks and also takes into account any promotional, product oriented, or customer oriented inserts such that each of the recipes is unique. An example of a multi-item bulk pick is an ensemble scenario where one hundred customers ordered a ring, and fifty of those customers also ordered the matching bracelet, and another twenty five customers ordered just the bracelet. This would yield a bulk pick with two items: one hundred rings, and seventy five bracelets. This example bulk pick is then assembled into separate customer orders from a total of three recipes: fifty of just the ring, fifty of the ring and bracelet, and twenty-five of just the bracelet. In addition, customer oriented inserts yield more variations of these recipes, but ultimately there is a single pick of just two items that was able to fulfill all of these permutations.
The ability to pick single item shipments and multi-line shipments in parallel via bulk pick reduces the amount of distance and time that it takes to pick the customer shipments. An additional benefit of using the bulk pick process and system is being able to utilize less sophisticated machinery to perform the final packaging step of processing the shipment.
The illustrated pick tour generating unit 20 in
As shown in
The order fulfillment system 10 of the present invention employs a cart building unit 128 that stores, transmits and receives data associated with a mobile cart, and specifically includes a container or tote data for use by the pick agent as how to best arrange totes or containers on a mobile cart employed by the pick agent. The tote data can correspond to data associated with specific totes as well as to sub-compartments within the totes. The totes and associated sub-compartments are arranged and scheduled consistent with the pick orders sent to the pick agent. Similar to the warehouse map unit 120 and the graph generating unit 124, the cart building unit 128 can be a separate element or can form part of the pick tour generating unit 20. The totes on the mobile cart can be uniquely identified by identification (ID) information, which can include any type of suitable data, including for example alphanumeric data. The ID information can be encoded in a barcode that can be placed on the front or back of the tote that is scanned while on a cart or on a suitable transport system (e.g., a conveyor belt) within the warehouse. The tote can include one or more sub-compartments, such as for example four sub-compartments or quadrants. In addition to the barcodes on the exterior of the tote, each sub-compartment of the tote can also include unique identification information, such as a barcode. The ID information associated with each sub-compartment is used and scanned by the pick agent. The sub-compartments can house one or more selected items associated with a shipment. The ID information can be exchanged with the cart building unit 128 and/or with the pick tour generating unit 20.
The pick tour generating unit 20 can for example perform a mapping between the customer orders or shipments and warehouse locations in the form of a map, such as a shipment-bay graph. This mapping or graphing can be performed by the graph generating unit 124. The graph generating unit 124 can be a separate element or can form part of the pick tour generating unit 20. The graphing can be performed in a manner so as to optimize the time and distance that a pick agent needs to travel when picking or selecting certain items. The items correspond to one or more portions of one or more customer orders. The graphing can also be optimized so as to avoid potential collisions between pick agents and to consider the location of any selected transport system, such as conveyor belts, so as to ensure that the pick agent has relatively easy and speedy access to the transport system. The graph generating unit 124 also generates the graph employing shipments or customer orders that include more than one item located at more than one location.
The illustrated graph generating unit 124 can employ a value sorted tree map technique when generating the map or graph. An example of the value sorted tree map 130 is shown for example in
An example of the value sorted tree map 130 compared to traditional mapping techniques is shown in
The value sorted tree map 130 of the present invention ensures that the values or node links remain in a sorted order during access, insertion, and deletion which removes the need to sort all of the value nodes when deciding which node to process next in the graph. For example, as shown in
When creating the value sorted tree map 130, the incoming customer orders or shipments are analyzed by the order generating unit 14 to determine if the order is to be handled by the automated shipment system 16, by the pick agent as part of a pick tour plan or a pick tour, or a combination of both. When the system 10 with the assistance of the supervisor determines that the order or part of the order is to be handled by the pick agent, the pick tour generating unit 20 determines if the order includes items located at multiple different locations in the warehouse. The system can easily determine the warehouse bay from the warehouse location. If the bay node exists, then the quantity of the pick from the bay can be incremented. If the shipment node does not already exist in the map, the pick tour generating unit 20 creates a new graph or bay node in the map. The system then adds a link from the shipment node to the bay node in the graph and the pick tour generating unit 20 tracks the quantity of the shipment in the bay/node structure. The resultant graph or map is then value sorted by the first bay location and/or bay count, and then the subsequent bay location. The map is then sorted by location. The graph is processed in such a manner that optimizes the assignment of orders into an N number of the sub-compartments or the compartments of the mobile cart. Further, the system 10, such as through the pick tour generating unit 20 and/or the graph generating unit 124, analyzes the customer order and shipment information and inserts the shipment data into the graph and creates a new graph node for the shipment if the bay node does not exist. For each item of the shipment determine a corresponding warehouse location, and then determine a warehouse bay from the location. The system then adds a link in the graph between the bay node and the shipment node. The shipment graph is then value sorted by the first bay location, bay count, and then subsequent bay location.
The pick tour generating unit 20 then constructs a pick tour plan or a pick tour having pick instructions associated therewith. The pick tour plan and the pick tour essentially provide a schedule or list of tasks for the pick agent to follow. The pick tour plan is constructed or generated so as to optimize the path distance through the warehouse as well as the number of pick tasks that a pick agent can execute when eventually performing the pick tour. Factors that the order fulfillment system 10 considers when optimizing or constructing the pick tour plan can include but are not limited to avoiding impediments or obstacles within the warehouse, such as for example walls and machinery, preferred human walking paths, opportunistic drop-off points like the central conveyor belt and location stock density as well as travel distance and quantities of products picked. Permissions required of the pick agent are also considered as picking expensive items, oversized items, or fragile items may require different levels of authorization or skill sets to perform. For example, a new pick agent may not have permission to execute a tour that contains important or expensive items.
Further, the cart building unit 128 employs the pick tour plan to help construct the pick cart by determining the number of totes and sub-compartments, and associating therewith the appropriate identification information. The pick tour plans are preferably constructed or generated so as to include trips by the pick agents to generally the same number of bays as well as the same number of picks or items, while concomitantly minimizing the overall or total walking distance by the pick agent. The pick plans are constructed by mapping the shipments or customer orders collected by the order generating unit 14 with the warehouse configuration data stored in the warehouse map unit 120 by the graph generating unit 124. The shipments that include more than one location pick are placed in the graph. The shipments that are directed to a single piece or warehouse location can be later added to the below pick tour. The pick plan includes a list or set of pick tasks that are segmented or partitioned into selected warehouse locations, thus creating different pick tasks for each warehouse zone.
As shown in
When compartmentalized totes on the mobile cart are used, the slots 153 represent sub-compartments of the totes and are typically not re-used because the tote itself is used as the container of the product instead of a bag. Once all picks for all sub-compartments of the tote have been completed, the tote is then transported by automated conveyance or by moving the mobile cart to a destination for unloading the totes for further processing.
As shown in
Once the pick tour plan 156 is generated and transmitted to the mobile device of the pick agent, the pick tour 174 can be started by the pick agent. According to the present invention, the pick tour 174 includes shipments or orders that correspond to items at multiple locations in the warehouse. The pick tour generating unit 20 can add a task to an existing pick tour that corresponds to an item located in a convenient or “opportunistic” location along the existing pre-defined pick tour path of the pick agent. The pick tour generating unit 20 can sort the additional individual piece pick tasks by location and then compares the piece pick tasks to the current pick tours or the pick tours as of yet to be assigned. The additional piece pick task typically includes one or more items disposed at a single location that is opportunistically located along the walking path of existing pick tour. The opportunistic piece pick task added to a pre-existing pick tour is a pick task that meets selected heuristic calculations regarding the closeness of the location of the item to the pick agent, the remaining pick cart capacity, the additional time added to the existing pick tour, and overall collision or contention reduction with other piece pick tours. Other factors can include whether the pick agent has already visited the warehouse location as part of the current pick tour, and whether the item location is along or sufficiently near the path of the current pick tour. The closeness of the piece pick location can be calculated in terms of time and/or distance to the current pick agent and current pick tour path, and the pick tour generating unit 20 can define an overall maximum distance or time to be added to the current pick tour in order to add one or more selected piece pick tasks to the tour. Thus, the pick tour generating unit 20 contemplates adding one or more additional piece pick tasks to the tour provided that the maximum or overall distance and time added to the pick tour is at or below the maximum amounts.
The display 136 also includes a bottom region that includes a sub-region 148 that allows the pick agent to pause or cancel the pick tour, a display sub-region showing the number of tasks completed and the number of total tasks (sub-region 150), as well as a display sub-region that allows exception information to be entered or can be used as a visual indicator of the network connection status (sub-region 152).
Once the last item for a shipment is picked and placed in a slot or sub-compartment of the tote, the pick agent is instructed that the sub-compartment is now closed and the shipment has been fully assembled. This information can be conveyed to the pick agent through the mobile handheld device. The completed totes may then be taken off of the mobile cart and placed on a central conveyor belt or otherwise delivered to the next step in the packing and shipping process. Alternatively, the contents of the sub-compartment are then placed in shipping bags by the pick agent, and then the bags and/or the tote(s) are then placed on a central conveyor belt and are sent to the packing and shipping subsystem 22.
Once this information is determined, the pick tour generator 20 initially generates a pick tour plan 156, step 166. The pick tour plan 156 is constructed or generated so as to optimize the path distance through the warehouse as well as the number of pick tasks that a pick agent can execute when eventually performing the pick tour. The pick tour plan 156 includes location information of the customer items, including warehouse location and corresponding bay, as well as container and sub-compartment information of the mobile cart. The pick tour plan is then converted into a pick tour 174 by the pick tour generator 20, step 168. The pick tour 174 can include any information required by the pick our agent to conduct the pick tour, including the location information of the items to be picked, identification information of the items, and the quantity of the items to be picked. During the pick tour, the pick tour generator 20 can add a pick task to the current pick tour of the agent if the agent is located in a selected proximity to the item, step 170. This opportunistic piece pick enables orders to be processed by the order fulfillment system 10 as expeditiously as possible.
As shown in
Similar to the above in connection with the bulk pick order fulfillment unit 18, and as shown in
The automated fulfillment system 16 can receive bulk pick instructions from the bulk pick order fulfillment unit 18 and perform an automated picking of items to fulfill a customer order, step 184. As described above, the order generating unit 14 can be configured to group together a set of customer orders that share similar features into a larger bulk pick order, and then the bulk pick order data can be transmitted to the bulk pick order fulfillment unit 18. The bulk pick orders (e.g., a bulk order wave) are groupings of customer orders that may be picked or fulfilled in a warehouse in aggregate. The bulk pick orders are selected to optimize the fulfillment process by selecting orders that have certain features in common. The bulk pick order fulfillment unit 18 generates bulk pick tour data corresponding to one or more bulk pick tours that can be fulfilled by the automated fulfillment system 16.
The automated fulfillment system 16 can pick the selected bulk pick items and then place them in one or more totes or container elements. The totes are then conveyed by the conveyor system to the packing and shipping subsystem, step 186.
For items within the customer order that are not located in the automated fulfillment system 16, the system 10 via the bulk pick order fulfillment unit 18 can generate a bulk pick recipe and a bulk pick sheet for dissemination to a pick agent, as described above.
With reference to
The automated fulfillment system 16 then picks the selected items listed in the pick tour 174 and the places the items in one or more tubs, totes or containers, step 194. The tubs or totes are then conveyed by the conveyor system to the packing and shipping subsystem, step 196.
For items within the customer order that are not located in the automated fulfillment system 16, the system 10 via the pick tour generating unit 20 can generate a pick tour plan 156 or a pick tour 174 for dissemination to a pick agent, as described above.
Further, the order fulfillment system 10 allows for one or more items picked through either the bulk wave process or the pick tour process to be added to items picked by the automated fulfillment system 16 prior to transfer to the packing and shipping subsystem 22. This enables the system 10 to be able to add one or more items not located in the automated fulfillment system to be added to an order that is primarily filled by the automated fulfillment system. For example, as shown in
Following below and referenced above are more detailed descriptions of various concepts and associated hardware of the units of the order fulfillment system 10 of the present invention.

The wireless links may also include any cellular network standards used to communicate among mobile devices, including standards that qualify as 1G, 2G, 3G, 4G, or 5G. The network standards may qualify as one or more generations of mobile telecommunication standards by fulfilling a specification or standards such as the specifications maintained by the International Telecommunication Union. The 3G standards, for example, may correspond to the International Mobile Telecommunications-2000 (IMT-2000) specification, and the 4G standards may correspond to the International Mobile Telecommunications Advanced (IMT-Advanced) specification. Examples of cellular network standards include AMPS, GSM, GPRS, UMTS, LTE, LTE Advanced, Mobile WiMAX, and WiMAX-Advanced. Cellular network standards may use various channel access methods e.g. FDMA, TDMA, CDMA, or SDMA. In some embodiments, different types of data may be transmitted via different links and standards. In other embodiments, the same types of data may be transmitted via different links and standards.
The network 514 may be any type and/or form of network. The geographical scope of the network 514 may vary widely and the network 514 can be a body area network (BAN), a personal area network (PAN), a local-area network (LAN), e.g. Intranet, a metropolitan area network (MAN), a wide area network (WAN), or the Internet. The topology of the network 514 may be of any form and may include, e.g., any of the following: point-to-point, bus, star, ring, mesh, or tree. The network 514 may be an overlay network, which is virtual and sits on top of one or more layers of other networks 514′. The network 514 may be of any such network topology as known to those ordinarily skilled in the art capable of supporting the operations described herein. The network 514 may utilize different techniques and layers or stacks of protocols, including, e.g., the Ethernet protocol, the internet protocol suite (TCP/IP), the ATM (Asynchronous Transfer Mode) technique, the SONET (Synchronous Optical Networking) protocol, or the SDH (Synchronous Digital Hierarchy) protocol.

In some embodiments, the network system may include multiple, logically-grouped servers 516. In one of these embodiments, the logical group of servers may be referred to as a server farm 518 or a machine farm 518. In another of these embodiments, the servers 516 may be geographically dispersed. In other embodiments, a machine farm 518 may be administered as a single entity. In still other embodiments, the machine farm 518 includes a plurality of machine farms 518. The servers 516 within each machine farm 518 can be heterogeneous, and one or more of the servers 516 or machines 516 can operate according to one type of operating system platform (e.g., WINDOWS NT, manufactured by Microsoft Corp. of Redmond, Wash.), while one or more of the other servers 516 can operate according to another type of operating system platform (e.g., Unix, Linux, or Mac OS X).
In one embodiment, servers 516 in the machine farm 518 may be stored in high-density rack systems, along with associated storage systems, and located in an enterprise data center. In this embodiment, consolidating the servers 516 in this way may improve system manageability, data security, the physical security of the system, and system performance by locating servers 516 and high performance storage systems on localized high performance networks. Centralizing the servers 516 and storage systems and coupling them with advanced system management tools allows more efficient use of server resources.
The servers 516 of each machine farm 518 do not need to be physically proximate to another server 516 in the same machine farm 518. Thus, the group of servers 516 logically grouped as a machine farm 518 may be interconnected using a wide-area network (WAN) connection or a metropolitan-area network (MAN) connection. For example, a machine farm 518 may include servers 516 physically located in different continents or different regions of a continent, country, state, city, campus, or room. Data transmission speeds between servers 516 in the machine farm 518 can be increased if the servers 516 are connected using a local-area network (LAN) connection or some form of direct connection. Additionally, a heterogeneous machine farm 518 may include one or more servers 516 operating according to a type of operating system, while one or more other servers 516 execute one or more types of hypervisors rather than operating systems. In these embodiments, hypervisors may be used to emulate virtual hardware, partition physical hardware, virtualized physical hardware, and execute virtual machines that provide access to computing environments, allowing multiple operating systems to run concurrently on a host computer. Native hypervisors may run directly on the host computer. Hypervisors may include VMware ESX/ESXi, manufactured by VMWare, Inc., of Palo Alto, Calif; the Xen hypervisor, an open source product whose development is overseen by Citrix Systems, Inc.; the HYPER-V hypervisors provided by Microsoft or others. Hosted hypervisors may run within an operating system on a second software level. Examples of hosted hypervisors may include VMware Workstation and VIRTUALBOX.
Management of the machine farm 518 may be de-centralized. For example, one or more servers 516 may comprise components, subsystems and modules to support one or more management services for the machine farm 518. In one of these embodiments, one or more servers 516 provide functionality for management of dynamic data, including techniques for handling failover, data replication, and increasing the robustness of the machine farm 518. Each server 516 may communicate with a persistent store and, in some embodiments, with a dynamic store.
Server 516 may be a file server, application server, web server, proxy server, appliance, network appliance, gateway, gateway server, virtualization server, deployment server, SSL VPN server, or firewall, or any other suitable computing device, such as computing device 600. In one embodiment, the server 516 may be referred to as a remote machine or a node. In another embodiment, a plurality of nodes may be in the path between any two communicating servers.
