Description

BOM construction system and method for automating ship production

[0001] The present invention relates to a BOM construction system and method for ship production automation, and more particularly, to a BOM construction system and method for ship production automation that enables flexible production response by allowing design data to be reflected in production and transmitted to a production site.

[0002] Typically, in the shipbuilding industry, ships are designed using 3D CAD, and design data is provided to ship production sites through 2D drawings.

[0003] As a result, the production department cannot access 3D models of products produced during the design phase (excluding 2D paper drawings), product specifications such as material and thickness (BOM (Bill of Materials), welding data, processing data, and painting data), and must instead operate production equipment (e.g., welding) or proceed with production manually. Furthermore, the design department has difficulty monitoring how product production is being carried out on the production floor.

[0004] Therefore, a method is required to improve productivity by creating an effective BOM structure for design data and then delivering it to production managers.

[0005] Additionally, most domestic shipyards use Aveva Marine (AM) as their design 3D CAD tool. To transfer design data to production, a Product Lifecycle Management (PLM) system is required. However, most shipyards lack a reference for a PLM system that integrates design and production.

[0006] Some existing shipyards have attempted to achieve design / production consistency using a product called AVEVA NET, but because CAD and AVEVA NET do not use the same database but separate databases, the design-production data is disconnected, and as a result, digital manufacturing (DM) implementation has not been fully achieved.

[0007] Therefore, a new type of digital manufacturing system is required that enables flexible production response by unifying the DB so that design data can be directly utilized in production, and design data including design revision information can be reflected in production data and immediately transmitted to the production site.

[0008] The technology underlying the present invention is disclosed in Korean Patent No. 10-1091407 (announced on December 7, 2011).

[0009] The purpose of the present invention is to provide a BOM construction system and method for automating ship production that can implement digital manufacturing by building PLM by integrating design and production data.

[0010] The present invention provides a BOM construction system for ship production automation, comprising: a CAD-EBOM generation unit for generating EBOM (Engineering BOM) data in a CAD area based on a design model structure by modeling panel-specific members of each block for ship design in a CAD area; a PLM-EBOM generation unit for generating EBOM data in a PLM area based on an assembly unit structure by reflecting the production assembly order of each block in the EBOM data in the CAD area; an MBOM generation unit for generating MBOM (Manufacturing BOM) data by combining production information including work process information and welding information of each block with the EBOM data in the PLM area; and a BOP generation unit for generating BOP (Bill Of Process) data by combining the MBOM data corresponding to product information of each block with PBOM (Plant BOM) data, which is factory information for each block.

[0011] In addition, the ship design and production automation system may further include a CPS (Cyber ​​Physical System) simulation unit that performs CPS simulation using the generated BOP data.

[0012] In addition, the PLM-EBOM generation unit can generate EBOM data of the PLM area by rearranging the EBOM data of the CAD area according to the production assembly order of each block.

[0013] In addition, the MBOM generation unit can generate the MBOM data by combining and reconstructing production information including work process information and welding information for each assembly unit for each block within the EBOM data of the PLM area.

[0014] In addition, the MBOM generation unit can generate the MBOM data in block units and manage the top tree of the MBOM data in block units rather than line units.

[0015] In addition, the BOP generation unit can extract factory information that can be allocated to each block and detailed assembly unit that constitutes the block from the PBOM DB that hierarchizes each workstation, which is a component within the factory, and 3D model the process equipment of the factory and workstation for each factory, and then combine it with the MBOM data to generate the BOP data.

[0016] And, the present invention relates to a BOM construction method performed by a BOM construction system for ship production automation, comprising: a step of generating EBOM (Engineering BOM) data in a CAD area based on a design model structure by modeling members for each panel of each block for ship design in a CAD area; a step of generating EBOM data in a PLM area based on an assembly unit structure by reflecting the production assembly order of each block in the EBOM data in the CAD area; a step of generating MBOM (Manufacturing BOM) data by combining production information including work process information and welding information of each block with the EBOM data in the PLM area; and a step of generating BOP (Bill Of Process) data by combining the MBOM data corresponding to the product information of the block with PBOM (Plant BOM) data, which is factory information for each work of each block.

[0017] In addition, the BOM construction method may further include a step of performing a CPS (Cyber ​​Physical System) simulation using the generated BOP data.

[0018] According to the present invention, a BOM construction platform for ship production automation can be provided that can implement digital manufacturing by integrating CAD, PLM, and DM solutions and unifying production and design.

[0030] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings so that those skilled in the art can easily practice the present invention. However, the present invention may be implemented in various different forms and is not limited to the embodiments described herein. In addition, in the drawings, parts irrelevant to the description have been omitted to clearly explain the present invention, and similar parts have been designated with similar reference numerals throughout the specification.

[0031] Throughout the specification, when a part is said to be "connected" to another part, this includes not only the cases where the parts are "directly connected" but also the cases where the parts are "electrically connected" with other elements intervening. Furthermore, when a part is said to "include" a component, this does not exclude other components, but rather includes other components, unless otherwise stated.

[0032] The present invention relates to a BOM construction system for ship production automation, and can implement digital manufacturing (DM) by building PLM by integrating and coherentizing design and production data.

[0033] Shipbuilding operations are generally broadly divided into hull and outfitting operations. The automated system according to the embodiment of the present invention can be applied to hull assembly automation, but it can also be expanded to automate other areas, such as painting, in addition to welding for assembly.

[0034] Figure 1 is a drawing illustrating a typical automated hull assembly process. As illustrated in Figure 1, the hull assembly process can be broadly divided into the hull design, steel selection / preprocessing, processing, subassembly / panel (plate assembly), and mid-assembly / major assembly stages.

[0035] Hull design refers to the process of designing the structure, walls, etc. of a ship using 3D CAD. In addition to the 3D model, the design target may also include product specifications such as location, COG, material, and thickness. Steel selection and preprocessing are the processes of selecting and preprocessing the steel ordered for hull production, while processing refers to the process of cutting the received steel into appropriate sizes. Subassembly / panel (plate assembly) is the assembly process of the smallest assembly unit that creates a block part. Panel (plate assembly) refers to the assembly of the main component that becomes the main plate base, and subassembly refers to the assembly of sub-components. Subassembly / major assembly refers to the process of assembling the subassembly hull parts into blocks.

[0036] Currently, during the production process, welding is either performed manually with a welding machine during assembly or manually controlled by human operators using automated welding equipment such as autocarriages, plate joint welding equipment, and longi-welding equipment. This hinders the effective utilization of design information. Furthermore, during design, it's difficult to monitor real-time production progress without visiting the factory in person.

[0037] In the following embodiments of the present invention, a BOM construction platform for ship production automation is proposed that uses an optimal BOM structure that allows design data to reach production facilities / equipment and automates BOM stages across multiple processes at once.

[0038] According to the proposed platform, it is possible to build a manufacturing innovation platform that can effectively transfer and apply design data to the production assembly process (e.g., welding robot, welding equipment), create a process that automatically produces according to the specifications of the set parts (automation realization), enable pre-simulation before production (CPS realization), and virtually check the progress status right away by linking the current factory's production process in real time (process and virtual factory simulation realization).

[0039] FIG. 2 is a drawing explaining the configuration of a BOM construction system for ship production automation according to an embodiment of the present invention, and FIG. 3 is a drawing explaining a BOM construction process for ship production automation according to an embodiment of the present invention.

[0040] As shown in Fig. 2, a BOM construction system (100) according to an embodiment of the present invention includes a CAD-EBOM generation unit (110), a PLM-EBOM generation unit (120), an MBOM generation unit (130), a BOP generation unit (140), and may further include a CPS simulation unit (150). Here, the operation of each unit (110 to 150) and the data flow between each unit may be performed by a control unit (not shown).

[0041] This BOM construction system (100) may be implemented as a computer device that is physically configured and includes a processor, memory, a user interface input / output device and a storage device, a network input / output unit, etc., or may be implemented by an application program running on a computer device or a user terminal.

[0042] First, the CAD-EBOM generation unit (110) can model the panel-specific members of each block for ship design in the CAD area (e.g., AM CAD) and generate EBOM (Engineering BOM) data (10) in the CAD area based on the design model structure.

[0043] In addition, the PLM-EBOM generation unit (120) can generate EBOM data (20) of the PLM area based on the assembly unit structure by reflecting the production assembly order of each block in the EBOM data (10) of the generated CAD area.

[0044] The MBOM generation unit (130) can generate MBOM (Manufacturing BOM) data (30) by combining the work process information and welding information of each block with the EBOM data (20) of the generated PLM area.

[0045] Next, the BOP generation unit (140) can generate BOP (Bill Of Process) data (40) by combining MBOM data (30) corresponding to product information of each block and PBOM (Plant BOM) data (35) which is factory information for each task of each preset block.

[0046] Finally, the CPS simulation unit (150) can perform a CPS (Cyber ​​Physical System) simulation using the finally generated BOP data (40) to obtain simulation data (50).

[0047] At this time, as shown in Fig. 3, among the data of each process, two EBOM data (10, 20) implemented in the CAD area and the PLM area correspond to product information, PBOM data (35) corresponds to factory information, and BOP data (40) corresponds to data combining product information and factory information.

[0048] In addition, the generated data of each process is largely divided into three areas, namely, CAD area (A), PLM area (B), and DM area (C). It can be seen that No. 10 corresponds to data of CAD area (A), No. 20 to 40 correspond to data of PLM area, and the remaining No. 50 corresponds to data of DM area (C).

[0049] According to the present invention, digital manufacturing can be implemented by integrating CAD, PLM (Product Lifecycle Management) and DM (Digital Manufacturing) solutions and making production and design consistent.

[0050] Figure 4 is a drawing that further explains each process of Figure 3. As shown in Figure 4, according to the present invention, in the shipbuilding industry, a BOM for production can be created from design data, an MBOM can be created from an EBOM, and a BOP can be sequentially configured by combining the MBOM and the PBOM, after which a simulation can be performed.

[0051] Below, the proposed system is described in more detail using the automation of the keel assembly as a representative example.

[0052] First, the CAD-EBOM generation unit (110) can generate EBOM (10) data in the CAD area based on the design model structure by modeling the panel-specific members of each block for ship design in the CAD area.

[0053] An EBOM is a BOM structure designed and modeled in the design department. Typically, designers model a ship's profile as a collection of components called panels. Each component can be a single part, consisting of plates, sub-assemblies, and reinforcements.

[0054] Figure 5 is a drawing showing an example of modeling a slit panel using AM CAD.

[0055] As shown in Figure 5, the designer models the hull panel by unit called Panel, and the Panel can be separated into sub-structures such as PLATE, STIFF (Stiffener, Reinforcement). When modeling is performed in this way, ① hierarchical data consisting of BLOCK - PANEL - sub-sub-material, ② material properties (e.g. weight, position, COG, material, thickness, etc.), and ③ 3D shape data can be created. The CAD program used at this time is not only AM CAD, but also Siemens' NX, Dassault's CATIA, etc.

[0056] Here, the hierarchy (tree structure) from BLOCK - PANEL - sub-assembly is determined by the design and corresponds to the tree structure used by the designer. However, the hierarchy obtained during the design phase does not reflect the actual assembly order during the production phase.

[0057] Therefore, the tree structure of ① in Fig. 5 needs to be reconstructed from a production perspective in order to effectively transfer design data to the production process.

[0058] To this end, the PLM-EBOM generation unit (120) can generate EBOM data (20) of the PLM area based on the assembly unit structure by reflecting the production assembly order of each block in the EBOM data (10) of the CAD area.

[0059] Specifically, the PLM-EBOM generation unit (120) can generate EBOM data (20) of the PLM area by rearranging EBOM data (10) of the CAD area according to the production assembly order of each block.

[0060] Figure 6 is a drawing exemplarily showing the process of creating an EBOM in the PLM area by reflecting the production assembly sequence in the EBOM data in the CAD area.

[0061] As previously explained, since the assembly order in production is not reflected in the CAD level EBOM (10), the PLM-EBOM generation unit (120) can reorganize the CAD EBOM data (10) of the CAD area to match the production assembly order, as shown in FIG. 6, and reconstruct it into a structure that reflects the production assembly order.

[0062] The left picture of Fig. 6 exemplarily shows a tree structure representing the production assembly order of blocks. It can be seen that large assemblies, medium assemblies, and small assemblies are hierarchically connected under the B15 block. The right picture of Fig. 6 shows the production assembly order and the EBOM data (20) of the PLM area reconstructed using the EBOM (10) of the CAD level. Here, by attaching the EBOM data of the CAD area to the production assembly order, the EBOM data (20) of the PLM area reflecting the production assembly order can be generated as shown in the right picture of Fig. 6.

[0063] Accordingly, it can be simply expressed as 'EBOM (20) in the PLM domain = EBOM (10) in the CAD domain + production assembly sequence'. In this way, if the EBOM tree was configured by panel unit at the CAD level of the previous stage, the EBOM tree can be configured by production assembly sequence unit at the PLM level.

[0064] Next, the MBOM generation unit (130) can generate MBOM data (30) by combining the work process information and welding information of each block with the EBOM data (20) of the PLM area. At this time, the embodiment of the present invention has an MBOM structure in which the top tree of the MBOM data is changed to a block rather than a line unit.

[0065] MBOM (Manufacturing BOM) is a production parts specification, and data such as processing method and sequence, economic feasibility, etc. can be organized in conjunction with production form, plan, etc.

[0066] Figure 7 is a diagram exemplarily showing a process of generating MBOM data by combining work process information and welding information with EBOM data in the PLM area. The left figure of Figure 7 shows an example of an EBOM (20) in the PLM area, and the right figure shows an example of an MBOM (30) implemented by combining work process and welding information with the EBOM (20) in the left figure.

[0067] Also, in Fig. 7, UA represents Unit ASS'Y, PA represents Panel ASS'Y, MA represents Mid ASS'Y, TA represents T-Bar ASS'Y, SA represents Sub ASS'Y, SP represents Small Piece (C.Plate, Stiffener type), and LP represents Longi. Piece (Longi. type).

[0068] In an embodiment of the present invention, the MBOM (30) may represent a reconstructed product that combines the work process information indicating which process is currently being worked on in the EBOM (combination between the production assembly sequence and the EBOM of the CAD area) (20) of the PLM area, the upper process and process flow of the EBOM process, and production information such as welding information.

[0069] Accordingly, it can be simply expressed as 'MBOM = EBOM in CAD + assembly sequence + work process information + welding information'.

[0070] Here, the purpose of constructing the MBOM (30) is to subdivide the BOM by process to provide flexibility for expansion beyond assembly to painting, decoration, etc. In addition, as previously explained, the field work unit and the design work unit are different, and by utilizing this MBOM (30), design information can be easily accessed from the perspective of the production assembly unit during production.

[0071] As shown in the bottom of Fig. 7, the work process information includes panel assembly (PA) / sub-assembly (SA) / mid-assembly (MA) / unit assembly (UA) included in the assembly process. When the final assembly is completed, one unit block is completed. Welding information includes welding length, trajectory, and length (+current, voltage).

[0072] If the work process information of each block and the detailed welding information for each process are attached to the EBOM (20) in the PLM area shown in the left figure of Fig. 7, the MBOM (30) can be completed as shown in the right figure.

[0073] In this way, the MBOM generation unit (130) can generate MBOM data (30) by combining and reconstructing work process information and welding information for each assembly unit for each block within the EBOM data (20) of the PLM area. In addition, the MBOM generation unit (130) can generate MBOM data (30) in block units and manage the top tree of the MBOM data (30) in block units rather than line units.

[0074] Figure 8 is a drawing conceptually showing the MBOM structure proposed in the present invention.

[0075] As shown on the left side of Figure 8, shipyards have traditionally structured MBOM data, which comprises the product structure, into a single hierarchical tree, from the ship's deck down to individual components, and structured it from a design perspective rather than a production process perspective. The existing MBOM structure required production workers to open and close the entire ship's deck to find design information relevant to their work process, resulting in significant slowdowns. Furthermore, because it wasn't a production-focused MBOM, production workers required separate design knowledge to find relevant information.

[0076] In contrast, as shown on the right side of Figure 8, the proposed MBOM data is implemented as an MBOM structure that changes the top-level tree from a line unit to a block unit, allowing management of the top-level tree by block unit rather than by line unit, which is the entire ship. Furthermore, unlike the existing MBOM structure, member affiliation can be further subdivided by process.

[0077] Here, the MBOM data (30) generated in this way represents product information, and the PBOM data (35) represents factory information. The following describes the process of generating BOP data (40) by combining the MBOM data (30) and PBOM data (35).

[0078] Figure 9 is a diagram showing an example of PBOM data constructed for each factory.

[0079] As shown in Fig. 9, PBOM data (35) may include factory hierarchy information constructed for each factory, and 3D modeling information for the factory and each facility within the factory. For example, the Yongyeon factory may have a shipyard, a plate factory, etc., and the shipyard may be composed of four BAYs, and each BAY may be composed of a grain mill / flat mill / curved forming factory / curved assembly factory / flat assembly factory, etc. In addition, facilities such as cranes and robots may exist in the corresponding process line.

[0080] Such PBOM data (35) can be built and stored in a PBOM DB (not shown). Accordingly, components of the factory, including the factory, process lines, platforms, cranes / gantry equipment, plastic / collaborative / slit welding robots, welders, carriages, welding materials, transport equipment, and painting equipment, can be managed virtually in a hierarchical manner.

[0081] FIG. 10 is a diagram exemplarily showing a process of creating a BOP by combining an MBOM and a PBOM in an embodiment of the present invention. The left figure of FIG. 10 illustrates internal information of a PBOM DB including block-specific workshop information, and the right figure illustrates the process of creating a BOP by combining PBOM result data, which extracts factory information allocated to each block and each detailed assembly unit constituting the block from the DB on the left, with a previously created MBOM.

[0082] As shown in Fig. 10, the BOP generation unit (140) hierarchizes the work sites, which are each component within the factory, and 3D models the process equipment of the factory and the work site to build factory information. Then, it searches for a factory that can extract and allocate process information to each block from the PBOM DB, and then combines it with the previously generated MBOM data (30) to generate BOP data (40).

[0083] For example, in a shipyard, there are multiple factories including Factory 1, Factory 2, and external factories, so there are factories assigned according to the detailed processes of each block. The BOP generation unit (140) can extract factory information that can be assigned to each block from the PBOM DB, and ultimately create a BOP (40) that combines product information (MBOM, 30) and factory information (PBOM, 35).

[0084] As a result, it can be simply expressed as 'BOP = Product Information (MBOM) + Work plant information for each detailed process that constitutes a block, such as a small or medium-sized batch, + PBOM of the relevant plant.'

[0085] The reason why the basic structure of MBOM (30) and BOP (40) is implemented in this manner in the embodiment of the present invention is explained as follows.

[0086] In traditional machinery manufacturing, the BOP (Board of Production) refers to a production plan that fully details the product, process, and plant to be produced. This plan is fully determined during the design phase. However, in the shipbuilding industry, separate departments exist to develop product design and production plans. Furthermore,

[0087] In the shipbuilding industry, there is a gap of at least one month between design and production, so changes to the factory or line for production after design occur almost daily.

[0088] For example, in the case of a built-up process, if there is only one factory, this part will not change, but in the case of a panel process (bonding of main boards, long joint bonding), there are multiple possible factories, and the factory can change at any time depending on the situation.

[0089] Therefore, when determining the transmission / LOT in the design, it is reasonable to decide which process to proceed with when the production plant is not completely determined, and the BOP should be flexibly changed to match changes in the production plan, and the responsible entity for control should also be different.

[0090] Therefore, in the embodiment of the present invention, the process and factory decisions are not determined in a single BOM structure, but the process is determined at the MBOM stage, and the factory or line is determined at the BOP stage, thereby enabling flexible response to changes in the production site.

[0091] Finally, the CPS simulation unit (150) can perform a simulation through CPS (50) using the generated BOP data.

[0092] CPS (50) refers to a system in which virtual design / production information and S / W simulation technology are combined with physical machine components, real-time data is shared, and monitoring and control are performed in cyberspace.

[0093] In the shipbuilding industry, designs are typically created using 3D CAD and data is then transmitted to the shipbuilding site via 2D drawings. Consequently, production often struggles to access design data beyond the 2D paper drawings (e.g., 3D product models, bills of materials (BOMs), PORs (product specifications such as material / thickness), and welding data). Consequently, accurate design data is difficult for the production site to access, and the design department struggles to understand how production is conducted.

[0094] According to an embodiment of the present invention, by generating an effective BOM structure based on such design data and then transferring it to the production site, productivity can be improved, and design / production can be integrated and made consistent through the construction of a CPS.

[0095] According to this, in production sites, product production becomes possible using design data, and automated equipment such as robots can be operated with minimal human intervention.

[0096] Design departments can use 3D simulations to preview production processes in a virtual factory. For example, during the design stage, a virtual 3D factory, virtual welding robots, and virtual components can be used to simulate assembly virtually.

[0097] Additionally, from a design perspective, virtual factory simulation becomes possible, allowing the current factory production status to be viewed in a virtual environment.

[0098] In the planning part, when reviewing a new factory, a virtual factory / equipment (e.g., crane, robot) is built and simulated in advance, enabling effective economic analysis when introducing the factory.

[0099] Figure 11 is a diagram illustrating the concept of a design / production integrated platform for consistency according to an embodiment of the present invention. The left figure of Figure 11 illustrates a conventional design / production platform, and the right figure illustrates a design / production integrated platform for consistency according to an embodiment of the present invention.

[0100] In the existing design / production platform, the CAD at the design level and the AVEVA NET at the production level do not use the same DB but use separate DBs, so the design-production data was disconnected, and as a result, it was difficult to implement DM as the design data progressed in one direction.

[0101] By building a BOM platform for CPS-based ship production automation according to an embodiment of the present invention, a CAD-PLM-DM solution is integrated into a single DB (One-DB) using a product (e.g., Siemens, Dassault), so that the DB is unified and design data (e.g., 3D Model, processing data, welding data, 3D Model location, COG, design product specification BOM (material, thickness, etc. design information)) can be directly utilized in production. Here, when using Siemens as an integrated solution product, CAD can be implemented with NX, PLM with Teamcenter, and DM with Tecnometix, and when using Dassault, CAD can be implemented with CATIA, PLM with ENOVIA, and DM with DELMIA.

[0102] Furthermore, according to the BOM construction system for automated ship production according to an embodiment of the present invention, design revision information is transmitted to the production level, enabling flexible production response. This facilitates DM implementation, as design data and its modifications are seamlessly transmitted to the production site.

[0103] According to the present invention as described above, digital manufacturing can be implemented by integrating CAD, PLM, and DM solutions and making production and design consistent.

[0104] In addition, according to the present invention, the DB of design and production data is unified, so that the design data can be directly utilized in production, and conversely, data produced in production can be continuously fed back to the design department.

[0105] While the present invention has been described with reference to the embodiments illustrated in the drawings, these are merely exemplary, and those skilled in the art will understand that various modifications and equivalent alternative embodiments are possible. Therefore, the true scope of technical protection of the present invention should be determined by the technical spirit of the appended claims.
