AI Technical Summary
In existing warehousing and picking systems, the flow of goods from multiple subsystems is difficult to synchronize, resulting in asynchronous flow of goods at picking stations. This leads to excessive occupancy of merging and packaging stations and blockage of upstream conveyor lines. Furthermore, it is difficult to predict the waiting time for goods to arrive at the picking station.
Orders are obtained through an order computer and goods are allocated. The goods are transported to temporary storage and picking stations using the first and second transportation systems. The control device defines the target sequence of goods and calculates the start time of transportation to ensure synchronized transportation and sorting processes.
Even under challenging conditions, it prevents asynchronous flow of goods at picking stations, improves system coordination and efficiency, reduces the occupancy of merging and packaging stations, and ensures smooth upstream transport lines.

Abstract
Description
Technical Field
[0001] This invention relates to a method for picking goods into an order loading aid in a warehousing and picking system. Furthermore, the invention relates to a warehousing and picking system for implementing the method, the warehousing and picking system having a first subsystem, a second subsystem, a first transport system, a second transport system, a first picking station, a second picking station, a temporary storage unit, a sorting device, an order computer, and a control device. Background Technology
[0002] Such methods and such warehousing and picking systems are largely known from the prior art. For example, US 10,427,873 B1 discloses a picking system and a picking method in which a package pattern is generated for an order, defining the package sequence. Furthermore, goods that can be transported in bags are distinguished from those that cannot. The former are removed and bagged at the picking station. The bagged goods and the non-bagged goods are transported simultaneously to the consolidation and packaging station. There, both types of goods are transferred to a single shipping unit.
[0003] A disadvantage of known picking systems and methods is that unfortunate timing, along with unpredictable or difficult-to-assess events along their transport routes, can lead to asynchrony in the flow of goods, triggering the transport of goods to the consolidation and packaging stations. This results in excessively long occupancy of the consolidation and packaging stations and, therefore, inevitably, also causes congestion on the upstream transport routes.
[0004] In particular, this relates to warehousing and picking systems involving goods from multiple subsystems that can only operate with difficulty in coordination, for example, subsystems comprising different manufacturers. Furthermore, it relates to warehousing and picking systems where it may be difficult to predetermine the waiting time from the request for goods to their actual arrival at the picking station. In particular, this relates to warehousing and picking systems where goods are manufactured only in part in relation to the order. Summary of the Invention
[0005] Therefore, the objective of this invention is to provide an improved method for picking goods into order loading aids and an improved warehousing and picking system. In particular, asynchrony in the flow of goods at the picking station should be avoided even under difficult conditions.
[0006] The objective of this invention is achieved by a method for picking goods into an order loading aid in a warehousing and picking system, the method comprising the following steps:
[0007] a) Obtain multiple orders through the order computer of the warehousing and picking system and determine the goods included in the respective orders;
[0008] b) For each of the acquired orders, a first order portion is determined by the order computer, the first order portion having a first part of the goods included in the corresponding order, the goods of the first order portion being provided in a first subsystem of the warehousing and picking system;

[0011] e) The first transport system of the warehousing and picking system transports the order loading auxiliary equipment from the first picking station to the temporary storage of the warehousing and picking system;
[0012] f) Temporarily store order loading auxiliary devices in the temporary register;
[0013] g) Using the first transport system, the order loading auxiliary device is moved from the temporary storage and delivered to the second picking station of the warehousing and picking system;
[0014] h) Define a target order for goods using an (electronic) control device, and provide the goods of the second order portion of the order at the second picking station according to the target order for goods, wherein the target order for goods predetermines the target order for the order, and the order is processed at the second picking station according to the target order for the order;
[0015] i) The goods of the second order portion of the order are transported to the sorting unit of the warehousing and picking system by means of a second transportation system;
[0016] j) Sorting the goods of the second order portion of the order in the sorting device according to the order of goods;
[0017] k) Using a second transport system, the goods of the second order portion are transported from the sorting device in the order of the goods and the goods of the second order portion of the order are transported to the second picking station;
[0018] l) At the second picking station, the goods loading configuration of the corresponding second order portion of the order is provided to the corresponding order loading auxiliary device;
[0019] - wherein the control device operates the first transport system and the first transport system transports the order loading auxiliary devices according to a predetermined order target sequence in order to implement the arrival according to step g), and
[0020] Before sorting the goods of the second order portion of the order according to the order of goods targets, the control device calculates the start time for the departure according to step g) and manipulates the first transportation system to trigger the departure according to step g) at the start time.
[0021] Furthermore, the objective of this invention is achieved by a warehousing and picking system for picking goods into order loading aids, the warehousing and picking system comprising:
[0022] - First subsystem, in which goods can be provided;
[0023] - Second subsystem, in which goods can be provided;
[0024] - Order Calculator
[0025] i) Used to acquire multiple orders and identify the goods included in the corresponding orders.
[0026] ii) For each of the acquired orders, a first order portion is determined, the first order portion having a first portion of goods included in the corresponding order, the goods of the first order portion being provided in a first subsystem of the warehousing and picking system.
[0027] iii) For each of the acquired orders, a second order portion is determined, the second order portion having a second part of the goods included in the corresponding order, the goods of the second order portion being provided in a second subsystem of the warehousing and picking system;
[0028] - First picking station, used for loading goods of the corresponding first order portion of the order to the corresponding order loading auxiliary device;
[0029] - A second picking station, configured to load goods of the corresponding second order portion of the order to the corresponding order loading auxiliary device;
[0030] - A temporary storage unit used to temporarily store (cache) order loading auxiliary components;
[0031] - A first transport system for transporting order loading auxiliary devices from a first picking station to a temporary storage unit and for removing order loading auxiliary devices from the temporary storage unit and transporting order loading auxiliary devices to a second picking station;
[0032] - An (electronic) control device for defining a target order of goods, and providing goods of a second order portion of the order at a second picking station of the warehousing and picking system according to the target order of goods, wherein the target order of goods predetermines a target order of orders, and the orders are processed at the second picking station according to the target order of orders;
[0033] - A sorting device for sorting the goods of the second order portion of the order according to the order of goods;
[0034] - A second transportation system for transporting the goods of the second order portion of the order to the sorting device and for removing the goods of the second order portion from the sorting device and transporting the goods of the second order portion of the order to the second picking station according to the order of goods.
[0035] The control device is further configured to,
[0036] - Operate the first transport system to transport order loading auxiliary devices according to the predetermined order target sequence, and
[0037] Before sorting the goods of the second order portion of the order according to the order of goods, calculate the start time for transporting the order loading auxiliary device from the buffer and manipulate the first transportation system so as to trigger the transport of the order loading auxiliary device from the buffer at the start time.
[0038] The proposed measures prevent asynchronous flow of goods at the picking station, even under difficult conditions. These measures are therefore particularly suitable for warehousing and picking systems involving goods from multiple subsystems that can only operate with difficulty in coordination, such as subsystems from different manufacturers. Furthermore, the proposed measures are particularly suitable for warehousing and picking systems where it may be difficult to predict the waiting time from the request for goods to their actual arrival at the picking station.
[0039] The control device is configured to calculate the start time and manipulate the first transport system such that the transport is triggered or initiated at the start time. For this purpose, the control device can manipulate the transport system before the start time, wherein the transport begins at the start time. Alternatively, the control device can manipulate the transport system at the start time to directly initiate the transport.
[0040] Preferably, the control device calculates the start time so that the order loading auxiliary device is provided substantially simultaneously (synchronously) at the second picking station along with the goods via the first transport system and the second transport system. Here, the control device can consider the transport time required to move the order loading auxiliary device from the buffer to the second picking station. Furthermore, the control device can consider the transport time required to move the goods of the second order portion to the second picking station. The corresponding transport time can also be calculated by the control device.
[0041] The first subsystem of the warehousing and picking system can in particular be formed by or include a warehouse, in which goods for a first order are provided and removed from or are capable of being removed in relation to the order. The first subsystem is therefore particularly suitable for providing goods that are self-deliverable (i.e., goods that require no further processing).
[0042] The second subsystem of the warehousing and picking system can be formed or included, in particular, by a production site in which the goods of the second order are manufactured in relation to the order. That is, the production site is configured in this case for manufacturing the goods of the second order in relation to the order. The production site can, in particular, be set up for manufacturing books, footwear, or clothing. Generally, the production site may also involve personalizing pre-made goods (value-added services). For example, clothing or footwear can be printed or embroidered. It is also conceivable to print and bind books in relation to the order.
[0043] Advantageously, the order loading aid is configured differently from a suspended bag. Specifically, the order loading aid can be configured as a container, carton, shipping packaging (shipping carton, shipping bag), etc. Accordingly, the first transport system in this case includes a transport technology different from suspended transport technology. The transport technology can be configured, for example, as a stationary (fixed to the ground) transport technology, particularly as a roller transport technology or a belt transport technology. Alternatively, the first transport technology can be configured as a mobile transport technology, for example including Automated Guided Vehicles (AGVs) or Autonomous Mobile Robots (AMRs).
[0044] The second transport system preferably includes overhead conveying technology for the suspended transport of hanging bags in which the goods of the second order are transported. Preferably, one item of the second order is transported in each hanging bag. If multiple items are transported simultaneously in one transport carrier or one hanging bag, it mainly involves goods of the same type. In particular, the hanging bags can be configured according to patent applications WO 2019 / 195871 A1 or WO 2020 / 150762 A1 and used in the manner described therein in the methods and warehousing and picking systems disclosed herein. While it is advantageous to transport the goods of the second order in hanging bags, it is also conceivable to use other loading aids for the goods of the second order.
[0045] At the first picking station, the goods provided at the first picking station can be used to load order loading aids.
[0046] The first picking station may be configured as an automated picking station, in particular including a picking robot.
[0047] Alternatively, the first picking station may be configured as a manual picking station. A manual picking station may include input and / or output devices. Preferably, the input and / or output devices have an output device, such as a screen, for outputting picking instructions, on which the operator receives the picking instructions. Furthermore, the input and / or output devices may have an input device, such as a keyboard or buttons, for inputting a receipt command, through which the operator can acknowledge (confirm) the picking process. The input and output devices may be provided, for example, via a touchscreen.
[0048] At the second picking station, the order loading aids can be loaded using goods provided at the second picking station via the second transportation system.
[0049] If goods are provided in hanging bags at the second picking station, loading of the order loading aid may include transferring the goods from the hanging bags to the order loading aid.
[0050] The second picking station may be configured as an automated picking station, particularly including a picking robot.
[0051] Alternatively, the second picking station may be configured as a manual picking station. A manual picking station may include input and / or output devices. Preferably, the input and / or output devices have output devices, such as a screen, for outputting picking instructions, which the operator receives on the output device. When goods are provided in hanging bags at the second picking station, the picking instructions may include instructions for removing goods from the hanging bags and / or instructions for placing goods in the order loading aid. Furthermore, the input and / or output devices may have input devices, such as a keyboard or buttons, for inputting acceptance commands, which the operator can use to acknowledge (confirm) the picking process. The input and output devices may be provided, for example, via a touchscreen.
[0052] The temporary register includes buffer bits where order loading auxiliary devices can be temporarily stored.
[0053] If the second transport system includes overhead conveyor technology, the sorting device can be advantageously configured as an array sorter.
[0054] Other advantageous embodiments and further extensions of the invention are derived from the description taken in conjunction with the accompanying drawings.
[0055] Advantageously, the second order portion is assigned to one of multiple second picking stations, and this assignment is considered as a pre-determined allocation for the first order portion. Thus, synchronization of order loading aids and goods for the second order portion is achieved even when multiple second picking stations are present. Here, the aforementioned allocation can...
[0056] - Randomly selected
[0057] - Based on the shipping loading aids already provided at the second picking station, the goods included in the corresponding order (with or without the second order loading aids) are transferred into the shipping loading aids.
[0058] - Based on order priority, multiple collected orders are processed at a second picking station in a predetermined order or at a predetermined time (step 1).
[0059] - Based on the structural form of the second picking station, wherein, in particular, the following second picking station is selected, which is preferably suitable for implementing step l), and / or
[0060] -Based on the load level of the second picking station, the goods of the first order portion and the goods of the second order portion of multiple orders are preferably evenly distributed to each existing second picking station.
[0061] If the allocation is based on the level of workload, it can be ensured that the individual warehouse workers (pickers) at the second picking station are not overburdened and are not unilaterally overloaded by the division of the first and second order sections.
[0062] Random allocation causes a uniform load level at the second picking station over a sufficiently long period of time, without the need to measure or control the maintenance of this uniform load level.
[0063] It is also conceivable to use a single shipping loading device to load goods from multiple orders (each with or without order loading devices). For example, a single pallet (shipping loading device) could be loaded with order loading devices from multiple orders, and these orders could be shipped together sequentially.
[0064] In the case of an allocation based on a second picking station structure, one could consider, for example, whether a picking robot at a specific second picking station is better suited for picking the goods in the second order than other picking robots at other second picking stations.
[0065] When allocation is based on order priority, a designated second picking station can be opened for expedited orders or operated at a lower load level. If such an expedited order arrives, the goods for that order can be processed or picked at such a second picking station.
[0066] Furthermore, it is advantageous that when step d) ends, that is, when the order loading auxiliary device for the first order portion is finished at the first picking station, an order for providing the goods for the second order portion is issued. This ensures that when the goods for the second order portion are provided, particularly when the goods for the second order portion are produced, the goods for the first order portion are provided in any case. This avoids overloading the sorting device with high safety, as the transport of the goods for the second order portion will not be delayed because the goods for the first order portion or the order loading auxiliary device have not yet been provided.
[0067] Advantageously, before the goods of the second order portion are transported to the second picking station, after being removed or produced, they are transported to the pre-sorting stage of the sorting device and pre-sorted there, and then transported to the final sorting stage of the sorting device. The final sorting stage is here specifically configured as an array sorting device. The sorting of the goods of the second order portion is achieved in a particularly efficient manner through the proposed measures. However, the two-stage sorting is not mandatory. The goods of the second order portion, after being removed or produced, especially in cases bypassing the pre-sorting stage, can be transported directly to the final sorting stage or directly to the array sorting device and sorted there.
[0068] It is also particularly advantageous that when step d) ends (i.e., when the order loading aid is loaded with the goods of the first order portion at the first picking station) and the goods of the second order portion are stocked in the pre-sorting stage or alternatively in the final sorting stage, the delivery of the order loading aid along with the goods of the first order portion to the second picking station is triggered. This achieves synchronization of the delivery of the order loading aid and the goods of the second order portion with high security.
[0069] Finally, and advantageously, the goods in the second order portion are transported to a buffer within the warehousing and picking system, located between the second subsystem and the pre-sorting stage, after being removed or produced. This buffer compensates for fluctuations in the flow of goods on the second transport system. This also results in an improved, more uniform load distribution on the sorting equipment. Attached Figure Description
[0070] To better understand the invention, it is illustrated in more detail with the aid of the following figures. In the figures:
[0071] Figure 1 An exemplary warehousing and picking system for picking goods is illustrated in a strongly simplified diagram. Detailed Implementation
[0072] Figure 1 An exemplary and schematic warehousing and picking system 1 for picking goods 2a, 2b into an order loading auxiliary device 3 is shown. The warehousing and picking system 1 includes a first subsystem 4 capable of providing goods 2a and a second subsystem 5 capable of providing goods 2b.
[0073] In addition, the warehousing and picking system 1 includes an order computer 6, which is further configured to acquire multiple orders and determine the goods 2a, 2b included in the respective orders.
[0074] Furthermore, the warehousing and picking system 1 has a first picking station 7 for loading order loading auxiliary devices 3 with goods 2a, a second picking station 8 for loading order loading auxiliary devices 3 with goods 2b, and a temporary storage unit 9 for temporarily storing order loading auxiliary devices 3. Additionally, the warehousing and picking system 1 includes a first transportation system 10, which is used to transport the order loading auxiliary devices 3 from the first picking station 7 to the temporary storage unit 9, and to remove the order loading auxiliary devices 3 from the temporary storage unit 9 and transport the order loading auxiliary devices 3 to the second picking station 8. In this example, the first transportation system 10 is also configured to transport goods 2a to the first picking station 7.
[0075] Furthermore, the warehousing and picking system 1 has a sorting device 11 for sorting goods 2b and a second transport system 12 for transporting goods 2b to and from the sorting device 11 and to the second picking station 8. In this example, the sorting device 11 includes a pre-sorting stage 13 and an adjacent final sorting stage 14, the final sorting stage being specifically configured as an array sorting device. However, it is also conceivable to construct the sorting device 11 differently, and for example, omit the pre-sorting stage 13. Additionally, an optional buffer 15 is located prior to the pre-sorting stage 13.
[0076] Finally, the warehousing and picking system 1 includes a control device 16, which is further configured to define a target order of goods and provide goods 2b at the second picking station 8 in the target order of goods.
[0077] As by Figure 1 As can be seen, the first transport system 10 connects to the first subsystem 4, the first picking station 7, the temporary storage unit 9, and the second picking station 8. The second transport system 12 connects to the second subsystem 5, the buffer 15, the pre-sorting stage 13, the final sorting stage 14, and the second picking station 8. Unlabeled transport technology is also derived from the second picking station 8.
[0078] In this example, the first subsystem 4 of the warehousing and picking system 1 is formed or includes a warehouse for providing goods 2a of the first order portion. The provided goods 2a can be moved out of the warehouse in relation to the order.
[0079] In this example, the second subsystem 5 of the warehousing and picking system 1 is advantageously formed or includes a production site. The production site is set up for manufacturing or completing goods 2b in relation to a second order. In particular, the production site may be set up for manufacturing or customizing books, footwear, or clothing.
[0080] In this example, the second transport system 12 includes a suspension conveying technique for transporting suspended bags 17, in which goods 2b of the second order portion are transported. Preferably, one item 2b of the second order portion is transported in each of the suspended bags 17. It is also conceivable that goods 2b are transported by coat hooks (and therefore without suspended bags 17), wherein, in this case, transporting exactly one item 2b with one coat hook is preferred. If multiple items 2b are transported simultaneously with one transport carrier or one suspended bag 17, it mainly involves goods 2b of the same type. In particular, the suspended bags 17 can be configured according to patent applications WO 2019 / 195871 A1 or WO 2020 / 150762 A1, and used in the manner described therein in the methods disclosed herein and the warehousing and picking system 1 disclosed herein. Although it is advantageous to transport goods 2b of the second order portion in suspended bags 17, it is also conceivable to use other loading aids for goods 2b of the second order portion.
[0081] In this example, the order loading auxiliary device 3 differs from the suspended bag 17. Specifically, the order loading auxiliary device 3 can be configured as a container, carton, shipping packaging (shipping carton, shipping bag), etc. Correspondingly, the first transport system 10 in this example also includes a transport technology different from the suspended transport technology. In particular, the first transport system 10 can be configured as a container transport technology, for example, a transport technology fixed to the ground for horizontally transporting goods 2a. Specifically, the first transport system 10 can therefore have a roller conveyor or a belt conveyor.
[0082] Now, Figure 1 The functions of the warehousing and picking system 1 shown are as follows.
[0083] The method for picking goods 2a and 2b into the order loading auxiliary device 3 in the warehousing and picking system 1 includes the following steps:
[0084] a) Obtain multiple orders through the order computer 6 and determine the goods 2a and 2b included in the corresponding orders;
[0085] b) For each of the acquired orders, the order computer 6 determines a first order portion, the first order portion having a first part of goods 2a included in the corresponding order, the goods of the first order portion being provided in the first subsystem 4;
[0086] c) For each of the acquired orders, the order computer 6 determines a second order portion, the second order portion having a second part of goods 2b included in the corresponding order, the goods of the second order portion being provided in the second subsystem 5;
[0087] d) At the first picking station 7, the goods 2a of the corresponding first order portion of the order are loaded onto the corresponding order loading auxiliary device 3;
[0088] e) The order loading auxiliary device 3 is transported from the first picking station 7 to the temporary storage device 9 by means of the first transport system 10;
[0089] f) Temporarily store the order loading auxiliary device 3 in the temporary storage 9;
[0090] g) The order loading auxiliary device 3 is transported from the temporary storage device 9 and delivered to the second picking station 8 by means of the first transport system 10;
[0091] h) The target order of goods is defined by the control device 16, and the goods 2b of the second order portion of the order are provided at the second picking station 8 according to the target order of goods, wherein the target order of goods predetermines the target order of the order, and the order is processed at the second picking station 8 according to the target order of the order;
[0092] i) The goods 2b of the second order portion of the order are transported to the sorting device 11 by means of the second transport system 12;
[0093] j) In the sorting device 11, the goods 2b of the second order portion of the order are sorted according to the order of goods;
[0094] k) Using the second transport system 12, the goods 2b of the second order portion are transported from the sorting device 11 according to the order of goods and delivered to the second picking station 8; and
[0095] l) At the second picking station 8, the goods 2b of the corresponding second order portion of the order are loaded and assigned to the corresponding order loading auxiliary device 3.
[0096] The first transport system 10 transports the order loading auxiliary device 3 in accordance with the predetermined order target sequence via the control device 16, so as to implement the delivery according to step g).
[0097] Furthermore, before sorting the goods 2b of the second order portion of the order according to the order of goods targets, the control device 16 calculates the start time for the transport according to step g) and manipulates the first transport system 10 to trigger the transport according to step g) at the start time.
[0098] If an order arrives at the warehousing and picking system 1, it is thus determined which goods 2a are provided in the first subsystem 4 (warehouse) and which goods 2b are provided in the second subsystem 5 (production site). Goods 2a are then transported from the first subsystem 4 to the temporary storage unit 9 and stored there.
[0099] Similarly, goods 2b are conveyed from the second subsystem 5 to the buffer 15. The buffer 15 is used to compensate for fluctuations in the flow of goods on the second transport system 12 and does not need to be forcibly set up. From there, goods 2b arrives at the pre-sorting stage 13 and then at the final sorting stage 14. In the sorting device 11, goods 2b are sorted according to the target order of the goods, which is defined by the control device 16.
[0100] The cargo target sequence is predetermined, specifying the order in which goods 2b will be provided at the second picking station 8. The cargo target sequence also determines the order target sequence, in which the orders will be processed at the second picking station 8 according to the stated order target sequence.
[0101] At the second picking station 8, the order loading auxiliary device 3 is loaded with the goods 2b of the corresponding second order portion. For this purpose, the order loading auxiliary device 3 must be transported from the temporary storage device 9 in advance.
[0102] To synchronize the arrival of the order loading auxiliary device 3 and the goods 2b of the second order portion at the second picking station 8, the control device 16 calculates the start time for transporting the order loading auxiliary device 3 from the temporary storage 9. Furthermore, the control device 16 manipulates the first transport system 10 to trigger the aforementioned transport at the start time. This calculation of the start time is performed before the goods 2b of the second order portion are sorted according to the desired order. By means of the proposed measures, it is ensured that the order loading auxiliary device 3 arrives at the second picking station 8 at the desired time and in the desired order.
[0103] By synchronously and predictively calculating the start time and order target sequence, imbalances in the picking process are avoided, particularly congestion of goods in the first subsystem 4 and the second subsystem 5, as well as overload of the temporary storage 9, buffer 15, pre-sorting stage 13, and final sorting stage 14 (and thus the sorting device 11). Advantageously, this takes into account, in particular, the uncertainty in the time schedule for producing goods 2b. That is, although the time for providing the second order portion of goods 2b cannot be accurately predicted in advance, congestion and overload are avoided (compared to the relatively accurately known time required for providing the first order portion of goods 2a).
[0104] Advantageously, when step d) ends, that is, when the order loading auxiliary device 3 for the first order portion of goods 2a is loaded at the first picking station 7, an order for providing the second order portion of goods 2b is issued. This ensures that when the second order portion of goods 2b is provided, in particular, produced, the first order portion of goods 2a is prepared in any case. This avoids overloading of the sorting device 11 with high safety, because the transport of the second order portion of goods 2b will not be delayed because the first order portion of goods 2a has not yet been provided, or the order status auxiliary device 3 has not been installed.
[0105] Of particular advantage is that when step d) ends (i.e., when the order loading auxiliary device 3 is loaded with the goods 2a of the first order portion at the first picking station 7) and the goods 2b of the second order portion are stored in the pre-sorting stage 13 or alternatively in the final sorting stage 14, the order loading auxiliary device 3, along with the goods 2a of the first order portion, is triggered to arrive at the second picking station 8. This achieves synchronization of the arrival of the order loading auxiliary device 3 and the goods 2b of the second order portion with high security.
[0106] In one embodiment of the described method, the second order portion is assigned to one of a plurality of second picking stations 8, wherein the assignment is considered as a pre-determined allocation for the first order portion. This achieves synchronization between the order loading auxiliary device 3 and the arrival of the goods 2b of the second order portion, even in the presence of multiple second picking stations 8.
[0107] The following are some additional examples of cargo target order and order target order. In particular, when multiple orders each have multiple goods 2b in a second order portion, the order target order and cargo target order can deviate from each other. In one example, there are orders 1, 2, and 3, which involve goods 2b of cargo types A, B, C, and D.
[0108]
[0109] An exemplary pair of goods target order and order target order could be as follows: Goods target order = ABCABC DC, Order target order = 123. For the same goods target order = ABC ABC DC, but also possible order target order = 213, the pair of goods target order = DC ABC ABC would result in order target order = 312 or 321.
