Description

Technical Field

[0001] This invention belongs to the field of aviation equipment inspection technology, specifically relating to a method and system for constructing the disassembled structure of aircraft target products. Background Technology

[0002] This section provides background information relating to this application, but such information does not necessarily constitute prior art.

[0003] Modern aircraft development is an extremely complex systems engineering project, characterized by its complex product composition, complex application technologies, huge financial investment, long development cycle, wide range of professional fields involved, massive process data, and global collaborative development.

[0004] Aircraft development is typically divided into multiple development phases in the horizontal time dimension and into various levels of system components in the vertical spatial dimension. In the horizontal aircraft development process, aircraft projects revolve around product requirements capture, functional definition, architecture design and trade-offs, product implementation and integration, requirements-based product verification, and product delivery and customer support. The relevant systems engineering processes ultimately revolve around the development and implementation of each level of the product in the vertical dimension. Summary of the Invention

[0005] This section provides a general overview of the application, rather than a full disclosure of the entire scope or all features of the application.

[0006] The purpose of this invention is to provide a method and system for constructing the decomposed structure of an aircraft target product. Due to the complexity and technical expertise of aircraft development, in order to reduce the difficulty of developing the target product (also known as the project product), shorten the development cycle, improve development efficiency, and reduce project risks, it is an urgent problem to be solved in the project development process to decompose the complex target product into smaller, easier-to-manage product units.

[0007] The technical solution of this invention is implemented as follows: In a first aspect, this application provides a method for constructing the decomposed structure of an aircraft target product, the method comprising: Based on the demand information of the target aircraft product, the key characteristic parameters of the target aircraft product to be decomposed are determined. The key characteristic parameters are used to determine the development type and development mode of the target aircraft product. The aircraft development type and development mode are determined based on the key characteristic parameters of the target aircraft product to be decomposed. The aircraft target product is developed according to the development type and the development mode at various levels to obtain product data of the aircraft target product. The development of the aircraft target product at various levels includes determining whether an enabling product is needed for each level of the target product based on actual needs.

[0008] The target products in this application include two categories: the final product of the project and its various sub-products, and the project enabling products required for the final product and its various sub-products. The final product refers to the aircraft itself delivered to the end customer to perform its mission. Project enabling products refer to lifecycle support products (such as R&D design, manufacturing, testing and verification, transportation and deployment, user training, operation and maintenance, and retirement-related products) that facilitate the development and use of the final product and its various sub-products throughout their lifecycle. By including enabling products, the project scope is more complete, the project objectives are clearer, and the target aircraft itself and its decomposed product units can more reliably achieve their lifecycle processes, including manufacturing, testing and verification, and transportation and deployment. This leads to more efficient acquisition of accurate, comprehensive, and reliable product data for the target aircraft, reducing delays and rework caused by certain products failing to achieve their lifecycle processes, thereby improving development efficiency while reducing project costs and schedule risks. Since the final product and its enabling products are interdependent, they need to be considered as a whole in the project. Therefore, the decomposition structure of the target aircraft product in this application is a collection of the product decomposition structure of the final product of the project and the product decomposition structure of the related enabling products.

[0009] The term “development at each level” as used in this article refers to developing each level of the target aircraft product vertically, thereby obtaining product data for each level of the target aircraft product.

[0010] The term "product data" as used in this application refers to the product data items for each target product, including but not limited to product number, product name, product manager, product definition information, product verification information, and product usage and maintenance information.

[0011] The method for constructing the decomposed structure of an aircraft target product in this application develops the aircraft target product at various levels according to the development type and development mode to obtain product data of the aircraft target product. The development of the aircraft target product at various levels includes determining whether an enabling product is needed for each level of the target product based on actual needs.

[0012] The method for constructing the decomposition structure of aircraft target products according to this application can decompose complex aircraft target products into smaller, more manageable product units, thereby reducing the difficulty of developing target products, shortening the development cycle, improving development efficiency, and reducing project risks. On the other hand, this method includes determining whether enabling products are needed for target products at each level based on actual needs. By including enabling products, the project scope becomes more complete and the project objectives become clearer. This further enables the target aircraft product itself and its decomposed product units to more reliably complete their life cycle processes, such as manufacturing, testing and verification, and transportation and deployment. This allows for more efficient acquisition of accurate, comprehensive, and reliable product data for the target aircraft product, reducing delays and rework caused by certain products failing to complete their life cycle processes, such as manufacturing, testing and verification, and transportation and deployment.

Detailed Implementation

[0049] The present application will now be described in detail with reference to the accompanying drawings and exemplary embodiments thereof. It should be noted that the following detailed description is for illustrative purposes only and is not intended to limit the scope of the application. Furthermore, the same reference numerals are used to denote the same parts in the various drawings.

[0050] It should also be noted that, for clarity, not all features of the actual specific embodiments are described and shown in the specification and drawings. In addition, in order to avoid unnecessary details from obscuring the technical solutions of interest in this application, only the arrangement structure closely related to the technical content of this application is described and shown in the specification and drawings, while other details that are not closely related to the technical content of this application and are known to those skilled in the art are omitted.

[0051] Product Breakdown Structure (PBS) (also referred to as the target product breakdown structure in this paper) is a hierarchical structure of products to be generated from the target product deliverables, used to break down complex target products into manageable, smaller product units.

[0052] It is worth noting that in the field of aircraft development (such as civil aircraft development), the concepts of Product Breakdown Structure (PBS) and Product Structure (PS) are often confused. Product Structure (PS) refers to the detailed list and structure of the components required for a product, often also called the Bill of Materials (BOM). Broadly speaking, it also includes the collection of all associated data information. By organizing related data information hierarchically and structurally, it provides data assurance for different business domains. In the aircraft development process, product data is typically constructed and organized based on different business perspectives, revolving around the data management process throughout the entire aircraft product lifecycle. This forms xBOM views for different business units (such as design, manufacturing, and service), meeting the needs of different business domains for managing, viewing, and using product data and information. For example, the Engineering Bill of Materials (EBOM) describes the compositional relationships of a product from a functional and physical perspective, reflecting all structural and system components involved in product assembly in the engineering view. It serves as the business carrier for transmitting design data downstream and is the foundation for manufacturing, support, and other processes.

[0053] Since the Product Breakdown Structure (PBS) is a hierarchical breakdown of the products required for a project in project management, it can be said that the PBS is a Product Structure (PS) from a project management perspective. However, the Bill of Materials (BOM) is usually mainly used to present a hierarchical view of the aircraft itself across different business units. The inventors of this application realized that in aircraft projects, the PBS should also cover other enabling products besides the aircraft itself to ensure the integrity of the project scope, promote comprehensive planning in work breakdown, cost breakdown, resource breakdown, etc., and avoid rework and delays due to omissions. Therefore, the final product (aircraft) in the PBS will be gradually transformed into a Product Structure (PS) during the development process and managed in the Product Lifecycle Management (PLM) system. In addition, in project management, the PBS is usually decomposed to the supplier work package / equipment level, while the Product Structure (PS) needs to be decomposed to the part level.

[0054] Currently, there is little research on Product Breakdown Structure (PBS) construction methods, or the concepts of Product Breakdown Structure (PBS) are often confused with Product Structure (PS), and generally, the enabling products of the project are not covered, resulting in incomplete project objectives and scope, which to some extent increases the project development risk.

[0055] To overcome the shortcomings of existing technologies, the purpose of this application is to provide a method and system for constructing the decomposed structure of aircraft target products, aiming to achieve the following objectives during the aircraft model development process: a) Clearly define all products to be delivered in the aircraft project, and establish clear objectives and scope for the project; b) Provides reference for formulating procurement strategies, manufacturing and assembly strategies, subcontracting cooperation strategies, etc., and can be used in conjunction with procurement strategies, manufacturing and assembly strategies, subcontracting cooperation strategies, etc., to facilitate the establishment of product manufacturing and assembly solutions; c) Display the target products in a visual, hierarchical, and categorized manner to more clearly present the relationship between the target products and their components; d) Within the model range, establish a collaborative research and development working environment to achieve parallel collaboration in engineering design, process manufacturing, project management, supply chain management, and logistics management; e) Facilitates requirement capture based on each product level, and enables layer-by-layer integration and verification of each product level; f) Facilitates the identification of the activities, resources, and dependencies required to obtain the target product at each level of the Product Breakdown Structure (PBS), and promotes the construction of Work Breakdown Structure (WBS), Cost Breakdown Structure (CBS), Resource Breakdown Structure (RBS), etc. g) Facilitates inspection to ensure the integrity of the work packages in the work breakdown structure (WBS), i.e., covering all target products of the product breakdown structure (PBS); h) Used in conjunction with Work Breakdown Structure (WBS), product development process, and milestones to facilitate the development of project development plans.

[0056] Next, exemplary embodiments of the method and system for constructing the breakdown structure of an aircraft target product according to this application will be described in detail with reference to the accompanying drawings.

[0057] Example 1 Figure 1A and Figure 1B This is a flowchart illustrating a method for constructing an exploded structure of an aircraft target product according to an embodiment of this application.

[0058] This invention provides a method for constructing the decomposed structure of an aircraft target product, comprising the following steps: like Figure 1A As shown, in step S10, the key characteristic parameters of the aircraft target product to be decomposed are determined based on the demand information of the aircraft target product. The key characteristic parameters are used to determine the development type and development mode of the aircraft target product.

[0059] In some implementations, the demand information for the target aircraft product includes, but is not limited to, target users, market positioning, mission objectives (e.g., air passenger transport, air cargo transport, weather modification, emergency communications, forest fire fighting, agricultural and forestry plant protection, etc.), and the key characteristic parameters of the target aircraft product include, but are not limited to, payload, range, operating speed, operating altitude, takeoff and landing field length, etc.

[0060] In step S20, the aircraft development type and development mode are determined based on the key characteristic parameters of the target aircraft product to be decomposed.

[0061] In some exemplary embodiments, the aircraft development type may include entirely new development, improved development, modified development, or modified / upgraded development, and the development mode may include a development mode based on independent component product units, a development mode based on large system integration, or a model-based systems engineering development mode.

[0062] In step S30, the aircraft target product is developed according to the development type and the development mode at various levels to obtain product data of the aircraft target product.

[0063] In the embodiments of this application, the development of the target aircraft product according to various levels S30 may include determining whether an enabling product is needed for each level of target product based on actual needs.

[0064] The method for constructing the decomposed structure of an aircraft target product in this application develops the aircraft target product at various levels according to the development type and development mode to obtain product data of the aircraft target product. The development of the aircraft target product at various levels includes determining whether an enabling product is needed for each level of the target product based on actual needs.

[0065] The method of this application for constructing the decomposed structure of aircraft target products is adopted; On the one hand, it can break down complex aircraft target products into smaller, more manageable product units, thereby reducing the difficulty of developing target products, shortening the development cycle, improving development efficiency, and reducing project risks. On the other hand, this method includes determining whether enabling products are needed for target products at each level based on actual needs. These enabling products are lifecycle support products necessary to promote the development and use of the target product during its lifecycle (such as products related to R&D design, manufacturing, testing and verification, transportation and deployment, user training, use and maintenance, and retirement). By including enabling products, the project scope becomes more complete and the project objectives become clearer. This further enables the aircraft target product itself and its decomposed product units to more reliably realize its lifecycle processes such as manufacturing, testing and verification, and transportation and deployment. As a result, accurate, comprehensive, and reliable product data of the aircraft target product is obtained more efficiently, reducing delays and rework caused by certain products being unable to realize their lifecycle processes such as manufacturing, testing and verification, and transportation and deployment. This further improves development efficiency while reducing project costs and schedule risks.

[0066] In some exemplary implementations, such as Figure 1B As shown, the development of the target aircraft product according to various levels S30 may include developing the first-level target aircraft product according to the development type and development mode S300, that is, in Figure 1B The first-level aircraft target product development is carried out when m=1 as shown. The first-level aircraft target product development S300 may include determining whether an enabling product is needed for the first-level aircraft target product based on actual requirements S360.

[0067] In some exemplary implementations, such as Figure 1B As shown, the development of the first-level aircraft target product S300 may also include determining the multiple aircraft target sub-products included in the first-level target product according to the aircraft hierarchical classification rules and the aircraft architecture S310.

[0068] Continue as Figure 1B As shown, in some exemplary embodiments, the development of the first-level aircraft target product S300 may further include: after performing step S310, judging and evaluating each of the plurality of aircraft target sub-products S320 to obtain product data for each of the plurality of aircraft target sub-products.

[0069] refer to Figure 2A In some exemplary embodiments, determining each of the plurality of aircraft target sub-products in S320 may include: determining whether one or more of the plurality of aircraft target sub-products are equipment-level products in S321.

[0070] In some exemplary embodiments, reference continues to be made. Figure 2AIf the aircraft target sub-product among the plurality of aircraft target sub-products is an equipment-level product (i.e., the judgment result of S321 is yes), then the product data of the aircraft target sub-product is determined.

[0071] In some exemplary embodiments, if the aircraft target sub-product among the plurality of aircraft target sub-products is not an equipment-level product (i.e., the determination result of S321 is no), then the aircraft target sub-product among the plurality of aircraft target sub-products is evaluated to determine whether development is required for the aircraft target sub-product among the plurality of aircraft target sub-products (S322). Figure 2A As shown.

[0072] In some exemplary implementations, such as Figure 2A As shown, when an aircraft target sub-product among the plurality of aircraft target sub-products is determined to require development (i.e., the determination result of S322 is yes), development S300 is performed on the aircraft target sub-product among the plurality of aircraft target sub-products to obtain product data for the aircraft target sub-product. For example... Figure 2A As shown, in step S300, the development of the target product at level m+1 is carried out. In this case, m+1=2, that is, the target sub-product is the second-level target product.

[0073] In some exemplary implementations, return to reference Figure 1B The development of the target sub-product among the plurality of target sub-products S300 may include: determining, based on actual needs, whether an enabling product is required for one or more target products in the second level of target products S360.

[0074] In some exemplary implementations, such as Figure 2A As shown, if a second-level target product among one or more second-level target products is determined to be unnecessary to develop (i.e., the judgment result of S322 is no), the product data S330 of the second-level target product can be determined.

[0075] In some exemplary implementations, such as Figure 2B As shown, when it is determined that an enabling product is required for the first-level aircraft target product, the process S380 for constructing product data for determining the enabling product may include the following steps: In step S381, the key characteristic parameters of the enabling product to be decomposed are determined according to the requirements of the enabling product. The key characteristic parameters of the enabling product are used to determine the development type of the enabling product. In step S382, the development type of the enabling product is determined based on the key characteristic parameters of the enabling product to be decomposed; In step S383, the enabling product is developed according to various levels based on the development type of the enabling product, so as to obtain product data of the enabling product.

[0076] Example 2 This invention provides a system for constructing the decomposed structure of an aircraft target product, with reference to... Figures 3 to 5 The system for constructing the breakdown structure of aircraft target products may include: a development information determination module 100 and a hierarchical development module 200.

[0077] The development information determination module 100 can be configured to: determine the key characteristic parameters of the aircraft target product to be decomposed based on the demand information of the aircraft target product, wherein the key characteristic parameters are used to determine the development type and development mode of the aircraft target product; and determine the aircraft development type and development mode based on the key characteristic parameters of the aircraft target product to be decomposed.

[0078] The hierarchical development module 200 can be configured to: develop the aircraft target product according to each level based on the development type and the development mode, so as to obtain product data of the aircraft target product, wherein the development of the aircraft target product according to each level includes determining whether an enabling product is needed for each level of target product based on actual needs.

[0079] The system for constructing the breakdown structure of aircraft target products in this application includes: a development information determination module and a hierarchical development module.

[0080] This hierarchical development module develops aircraft target products according to various levels based on development type and development mode to obtain product data for the aircraft target products. Among them, developing aircraft target products according to various levels includes determining whether enabling products are needed for each level of target product based on actual needs.

[0081] The system for constructing the decomposed structure of aircraft target products according to this application can decompose complex aircraft target products into smaller, more manageable product units, thereby reducing the difficulty of developing target products, shortening the development cycle, improving development efficiency, and reducing project risks. On the other hand, this method includes determining whether enabling products are needed for target products at each level based on actual needs. By including enabling products, the project scope becomes more complete and the project objectives become clearer. This further enables the target aircraft product itself and its decomposed product units to more reliably complete their life cycle processes, such as manufacturing, testing and verification, and transportation and deployment. This allows for more efficient acquisition of accurate, comprehensive, and reliable product data for the target aircraft product, reducing delays and rework caused by certain products failing to complete their life cycle processes, such as manufacturing, testing and verification, and transportation and deployment. This further improves development efficiency while reducing project costs and schedule risks.

[0091] Continue to refer to Figure 4 In some exemplary embodiments, the evaluation module 16 of the first-level aircraft target product development module 1 can be configured to: if the aircraft target sub-product among the plurality of aircraft target sub-products is not an equipment-level product (i.e., if the result of the judgment by the judgment module 15 is no), then evaluate the aircraft target sub-product among the plurality of aircraft target sub-products to determine whether it is necessary to develop the aircraft target sub-product among the plurality of aircraft target sub-products.

[0092] refer to Figure 5 In some exemplary embodiments, the hierarchical development module 200 may further include a second-level target product development module 2. The second-level target product development module may be configured to: when an aircraft target sub-product among the plurality of aircraft target sub-products is determined to require development (i.e., when the evaluation result by the evaluation module 16 of the first-level aircraft target product development module 1 is yes, reference may also be made to...) Figure 2AThe flowchart shows the process of developing the aircraft target sub-product among the multiple aircraft target sub-products to obtain product data for the aircraft target sub-product, wherein the aircraft target sub-product is a second-level target product.

[0093] In some exemplary implementations, such as Figure 5 As shown, the second-level target product development module 2 may include an enabling product determination module 21 for the second-level target product. The enabling product determination module 21 for the second-level target product may be configured to determine whether an enabling product is required for one or more target products in the second-level target product based on actual needs.

[0094] Continue to refer to Figure 5 In some exemplary embodiments, the second-level aircraft target product development module 2 may further include a second-level enabling product development information determination module 22 and a second-level aircraft target product development module 23.

[0095] The development information determination module 22 for the second-level enabling product can also be configured to: when it is determined that an enabling product is required for the second-level aircraft target product (i.e., when the determination result of the enabling product determination module 21 for the second-level target product is yes), determine the key characteristic parameters of the enabling product to be decomposed based on the requirements of the enabling product, wherein the key characteristic parameters of the enabling product are used to determine the development type of the enabling product; and determine the development type of the enabling product based on the key characteristic parameters of the enabling product to be decomposed.

The development process of the enabling product is similar to the development process of the aircraft target product.

[0097] In some exemplary embodiments, the second-level target product development module 2 may further include a second-level target product product data determination module 27. The second-level target product product data determination module 27 may be configured to determine the product data of the second-level target product when one or more second-level target products are determined to be unnecessary to develop.

[0102] In some exemplary embodiments, the hierarchical development module 200 may further include an Nth-level target product development module N, where N≥3. The Nth-level target product development module may be configured to: develop the aircraft target sub-product among the plurality of aircraft target sub-products when the aircraft target sub-product among the plurality of aircraft target sub-products is determined to require development (i.e., when N=3, and the evaluation result by the evaluation module 26 of the second-level aircraft target product development module 2 is yes), to obtain product data of the aircraft target sub-product, wherein the aircraft target sub-product is a Nth-level target product.

[0103] In some exemplary embodiments, the Nth-level target product development module N may include an enabling product determination module (not shown) for the Nth-level target product. This enabling product determination module can be configured to determine, based on actual needs, whether an enabling product is required for one or more target products in the Nth-level target product hierarchy. Although the Nth-level target product development module is not shown in the accompanying drawings, those skilled in the art will understand that it has a similar configuration and function to the first-level and second-level target product development modules, and will not be described in detail herein.

[0104] Example 3 like Figures 6 to 8 As shown, an alternative implementation of a method for constructing the decomposed structure of an aircraft target product is illustrated, the method comprising the following steps: Process 1, Aircraft Product Process 600; Process 2, Enabling Product Process 660; Step 3: Build the project PBS 700; And process four, assess the correctness and completeness of the project's PBS.

[0105] Process 1: Aircraft Product Process 600 includes four activities: aircraft capability requirements analysis 610, determining aircraft development type and development model 620, aircraft single-level product development 630, and building aircraft product PBS 640.

[0106] The following describes the specific activities of the aircraft product process 600.

[0107] a) Activity 1: Aircraft Capability Needs Analysis 610. In this activity, by analyzing the limitations of existing aircraft equipment in terms of initial design positioning, airworthiness certification and design standards, and inherent defects, the aircraft capability needs are proposed, and the positioning and characteristic requirements of the aircraft are clarified.

[0108] b) Activity Two: Determine the aircraft development type and development model 620. For example, the aircraft development type is one of the following: entirely new development, improved development, modified development, or retrofit development; the aircraft development model is one of the following: a development model based on independent component product units, a development model based on large system integration, or a model-based systems engineering development model.

[0109] c) Activity Three: Single-Level Development of the Target Product (630). The initial target product is an aircraft. Aircraft development levels include, for example, aircraft level, system level, subsystem level, and equipment level. This step refers to conducting development work on a single target product at a single level according to the systems engineering process, completing the structural decomposition of the single target product. The systems engineering process typically includes common steps such as requirements analysis, functional analysis, architecture design, and requirements verification.

[0110] d) Activity Four: Constructing the Aircraft Product PBS 640. This activity includes three steps: updating the target aircraft product PBS 641, defining the product data of the target sub-products 642, and evaluating whether the target sub-products should be subcontracted to suppliers 643.

[0111] in: Since Activity 3 completed the architectural design of a single product and performed structural decomposition on that single product, the aircraft PBS level increases by one level after each completion of Activity 3. At this point, it is necessary to update the aircraft target product PBS 641 and obtain the target sub-products of the added level. Define the product data for each target sub-product 642 to obtain the aircraft product PBS.

[0112] Next, assess whether the target sub-products need to be subcontracted to suppliers 643: If subcontracting is not required, conduct product development activities (i.e., Activity 3) for each target product, and further construct the aircraft product PBS; if subcontracting is required, the target sub-product decomposition activity stops and the current state is maintained. For example, if the initial (first level) target product is an aircraft, after its development, the PBS level increases by 1 level (i.e., the current PBS is level 2); update the aircraft product decomposition structure 641 to obtain second-level target sub-products, such as System A, System B, System C, etc., define product data for System A, System B, System C, etc. 642 to obtain the current state of the aircraft product decomposition structure, and update it to the target product decomposition structure (as described in Process 3 below).

[0113] Next, for each of systems A, B, C, etc., it is evaluated whether it is subcontracted to a supplier 643. For example, if system C is subcontracted to a supplier, and systems A and B are not subcontracted to suppliers, then system C remains in its current state, and each of systems A and B is developed. The PBS level is increased by 1 level (i.e., the current PBS is three levels); the aircraft product breakdown structure 641 is updated to obtain the third-level target sub-products. For example, the target sub-products A1 and A2 corresponding to system A are obtained, and the target sub-products B1, B2, B3, and B4 corresponding to system B are obtained. Product data is defined for the target sub-products A1, A2, B1, B2, B3, B4, etc. 642 to obtain the current state of the aircraft product breakdown structure (as described in process three below) and it is updated to the target product breakdown structure.

[0114] Then, for each of the target products A1, A2, B1, B2, B3, B4, etc., it is evaluated whether it should be subcontracted to the supplier 643, as described above, and this process is repeated recursively.

[0115] In addition, regardless of whether subcontracting is done to suppliers, the current aircraft product breakdown structure will be updated to the breakdown structure of the project target product (as described in process three below).

[0116] In Process Two, the Enable Product Process 660 is conducted concurrently with the aircraft product development activities. Similar to the aircraft product process, the Enable Product Process also includes four activities: enabling product capability needs analysis, determining the type of enabling product development (in some implementations, this may also involve determining the type and mode of enabling product development), enabling product development, and constructing the enabling product PBS. The enabling product development can be completed by referring to the development process in the corresponding field.

[0117] In process three, the project PBS 700 is constructed based on the aircraft product PBS and enabling product PBS to form a breakdown structure of the aircraft project's target product. In some implementations, such as Figure 1B As shown, the decomposition structure of the aircraft target product is formed based on the product data of each of the multiple aircraft target sub-products and the product data of the enabling product.

[0118] Step four is to assess the correctness and completeness of the project's Product Breakdown Structure (PBS). The constructed PBS should meet all the needs arising in the project, including enabling needs arising in aircraft product development (such as manufacturing, testing and verification, transportation and deployment, training, use and maintenance, etc.), to ensure that the project's ultimate goals are achieved.

[0119] Preferably, in constructing the decomposition structure of the target product, various professional fields in the aircraft development life cycle should be considered, such as engineering design, process manufacturing, testing and verification, supply chain, marketing and sales, customer service, and information technology, to ensure the completeness and correctness of the decomposition structure of the target product.

[0120] As mentioned in Activity 4, not all target products need to be broken down to the equipment level; it depends on the subcontracting situation.

[0121] An aircraft project may use products from other aircraft projects, and these products should be identified. For example, in a modification and development project, products from a prototype may be reused; or there may be off-the-shelf products to be procured from suppliers, products that originated in those suppliers' projects. Although these products are generated outside the aircraft project, the project needs to use them, and delays or non-compliance with these products can have a significant impact on the target product. Identifying products from other projects can be achieved by defining new product data items.

[0122] Preferably, when constructing the product breakdown structure, different shapes, colors, or styles can be used to represent different product types. For example, a square can be used to represent most products in the product breakdown structure, while other shapes (such as circles or triangles) can be used to distinguish externally sourced products. Different colors can be used to represent products from different business domains, or products produced at different stages of development, etc. Figures 9 to 11 (As shown).

[0123] Preferably, when defining target products, each target product is assigned a unique identifier (this identifier belongs to the product data of the target product). More preferably, the uniqueness of each target product identifier is maintained during subsequent updates, use, and maintenance to ensure the accurate positioning of all target products in the product breakdown structure.

[0124] For certain derivative models, although most of the target products in the product breakdown structure (BBS) may be the same, it is still necessary to re-examine these seemingly identical target products when constructing the BBS for the derivative model, that is, to redefine the product data of the target products. From a project management perspective, each project is unique, and derivative projects may have new requirements for those target products. When constructing the BBS for derivative models, the target products can be listed in detail first, and if they can be reused after evaluation, they can be specifically marked.

[0125] Example 4 Figure 7 This is an example diagram illustrating the hierarchy of the decomposition structure of a target product according to an embodiment of this application, which employs a product decomposition structure construction method based on ATA2200.

[0126] The first level is the aircraft level, which includes the final product of the aircraft project (the aircraft itself) and the enabling products required by it (such as manufacturing and assembly products, testing and verification products, customer service products, maintenance and repair products, etc.).

[0127] The second level is the system level, which includes multiple target sub-products obtained by decomposing the first-level aircraft target product (i.e., second-level target products), such as flight control system, navigation system, communication system, power plant, fuel system, air conditioning system, hydraulic system and other systems, as well as structures such as fuselage, wings, tail, nacelle and other structures; in addition, it also includes enabling products (not shown) required for the second-level target products.

[0128] The third level is the subsystem level, which includes multiple target sub-products (i.e., third-level target products) obtained by evaluating and decomposing the target products of the second level one by one. For example, the target sub-products obtained by decomposing the fuel system in the second-level target product include, for example, the fuel storage subsystem, the fuel distribution subsystem, and the fuel measurement subsystem; in addition, it also includes the enabling products (not shown) required for the third-level target products.

[0129] The fourth level is the equipment level, which includes multiple target sub-products (i.e., fourth-level target products) obtained by evaluating and decomposing the target products of the third level one by one. For example, the target sub-products obtained by decomposing the fuel measurement subsystem in the third-level target product include fuel measurement computer, fuel quantity sensor, fuel level signaler, refueling control board, etc. In addition, it also includes the enabling products (not shown) required for the fourth-level target products.

[0130] Example 5 Figure 8 This is an example diagram illustrating the hierarchical breakdown structure of a target product according to another embodiment of this application, which adopts a development model based on independent segment product units. Each independent segment product unit includes a collection of systems and structures that can be designed, manufactured, assembled, tested, verified, and delivered as an independent target product.

[0131] The first level is the aircraft level, which includes the final product of the aircraft project (the aircraft itself) and the enabling products required by it (such as manufacturing and assembly products, testing and verification products, etc.).

[0132] The second level is the independent segment level, which includes multiple target sub-products obtained by decomposing the first-level aircraft target product (i.e., second-level target products). The second-level target products are independent segment product units, such as the nose, forward fuselage, mid-fuselage, mid-rear fuselage, rear fuselage, center wing, left wing, right wing, horizontal stabilizer, vertical stabilizer, left nacelle, right nacelle, nose landing gear, left main landing gear, right main landing gear, etc. In addition, it also includes enabling products (not shown) required for the second-level target products.

[0133] The third level is the system level, which includes multiple target sub-products obtained by decomposing the independent segment product units in the second-level target product (i.e., third-level target products). For example, multiple target sub-products obtained by decomposing the nose section, such as the nose structure and the systems included therein (the systems referred to here are the system parts located in the independent segment product unit, and...). Figure 7 (This may not be complete compared to the corresponding system described herein); in addition, it also includes the enabling products (not shown) required for the third-level target product.

[0134] The fourth level is the subsystem level, which includes multiple target sub-products (i.e., fourth-level target products) obtained by evaluating and decomposing the target products of the three levels one by one; in addition, it also includes the enabling products (not shown) required for the fourth-level target products.

[0135] The fifth level is the equipment level, which includes multiple target sub-products (i.e., fifth-level target products) obtained by evaluating and decomposing the target products of the fourth level one by one; in addition, it also includes the enabling products (not shown) required for the fifth-level target products.

[0136] Example 6 Figure 9 This is an example diagram illustrating the decomposition structure of a target product according to an embodiment of this application. In this embodiment, based on the demand information of the aircraft target product and the determined key characteristic parameters of the aircraft, the project is determined to be a completely new development type, based on a large system integration development model. According to the aircraft target product decomposition structure construction method provided in this application, the obtained decomposition structure of the aircraft target product includes aircraft level, large system level, system level, subsystem level, and equipment level. The target products at each level are as follows: Figure 9 As shown (not fully shown, and the enabling product is not shown).

[0137] Example 7 Figure 10 This is an example diagram illustrating the exploded structure of a target product according to another embodiment of this application. In this embodiment, based on the demand information for the aircraft target product and the determined key characteristic parameters of the aircraft, the project is determined to be... Figure 9 Based on the aircraft project shown, a modified development of a mission system was added. According to the decomposition structure construction method for the aircraft target product provided in this application, the hierarchy of the decomposition structure of the aircraft target product was obtained (the hierarchy is related to...). Figure 9 (The hierarchy described herein is consistent) and the target products at each level (not fully shown, and enabling products are not shown) are as follows: Figure 9 As shown.

[0138] Figure 10 The exploded structure of the target aircraft product shown is in Figure 9Based on the decomposed structure of the aircraft target product shown, the method and system of this application for constructing the decomposed structure of the aircraft target product can present different visual features for unchanging target products, changed target products, deleted target products, and newly added target products. Different visual features may include, but are not limited to, highlighting, color changing, and background transformation.

[0139] like Figure 10 As shown, the method and system for constructing the decomposition structure of aircraft target products according to this application can present unchanging target products in gray, changed target products in red, deleted target products with strikethrough lines, and newly added target products in green.

[0140] Alternatively, the method and system for constructing the decomposition structure of aircraft target products according to this application can differentiate between unchanging target products, changed target products, deleted target products, and newly added target products by defining new product data items.

[0141] Alternatively, the method and system of this application for constructing the decomposition structure of aircraft target products can filter, select, and structure the target products into four categories: unchanging target products, changed target products, deleted target products, and newly added target products, using visual features and specific product data items.

[0142] Alternatively, the method and system of this application for constructing the decomposed structure of aircraft target products can filter, select, and structure various categorizable target products (e.g., categorized by different business domains, different development stages, etc.) through visual features, specific product data items, etc.

[0143] The method and system for constructing the decomposition structure of aircraft target products according to this application can display the target products in a visual, hierarchical, and categorized form, making it easier to present the relationship between the target products and their components more clearly.

[0144] Example 8 Figure 11 This is an example diagram illustrating the decomposition structure of a target product according to another embodiment of this application. This embodiment is an exemplary implementation of an unmanned aerial vehicle (UAV) system, where the final product includes a UAV and a control center, which together constitute the UAV system. According to the decomposition structure construction method for aircraft target products provided in this application, the resulting hierarchy of the aircraft target product decomposition structure (device level not shown) and the target products at each level (not fully shown, and enabling products not shown) are as follows: Figure 9 As shown.
