Description

Technical Field

[0001] This invention relates to the field of cost estimation for the development of technical data deliverables in the automotive aftermarket, and in particular to a method and system for cost estimation of automotive aftermarket technical data deliverables. Background Technology

[0002] In the automotive aftermarket, the cost assessment of technical data deliverables, such as repair manuals, user manuals, and circuit diagrams, is a key basis for enterprises to conduct business pricing, budget control, cost accounting, resource optimization, and performance evaluation, directly affecting the enterprise's operation and management and efficiency.

[0003] Currently, traditional development cost estimation methods in the industry mainly rely on manual experience. The typical process is as follows: cost estimators manually search for and analyze similar previously developed deliverables based on client-provided reference materials such as Bill of Materials (BOM) and configuration lists. By comparing the differences between the two in terms of development standards, development materials, and development roadmaps, the cost data of the most similar historical deliverables is referenced and adjusted accordingly to estimate the development cost of the target deliverable, thus laying the foundation for accurate pricing by the business team. This traditional manual estimation method has the following significant drawbacks:

[0004] 1. Heavy workload and low efficiency: Due to the large number of historical deliverables, manual screening, analysis and identification of historical projects that can be used for reference, as well as detailed comparison of differences, are time-consuming, labor-intensive and arduous.

[0005] 2. The accuracy of results is highly dependent on personal experience: The accuracy of cost estimation heavily relies on the assessor's technical skills, project experience, and judgment of information completeness. Any slight differences in development standards, scope, and data can have a significant impact on costs. The lack of unified, objective quantitative standards leads to large fluctuations in assessment results from different personnel or under different circumstances, making it difficult to guarantee reliability.

[0006] 3. High management costs: In the absence of structured historical cost data, preliminary cost estimates based primarily on personal experience typically require multiple rounds of internal verification, review, and adjustment before being confirmed as relatively reasonable. This iterative communication and revision process generates significant hidden management costs.

[0007] In summary, existing technologies suffer from low automation, high reliance on human experience, and lengthy and costly calculation processes. Therefore, the industry urgently needs an automated, intelligent, and standardized method and system for calculating development costs to improve the efficiency of business quotations, ensure their accuracy, and reduce the burden on internal management. Summary of the Invention

[0008] The purpose of this invention is to overcome the shortcomings of the prior art and provide a method and system for calculating the development cost of automotive aftermarket technical data deliverables. This method transforms scattered cost influencing factors and work hour data into a structured, interconnected knowledge base. Based on the interconnected development roadmap element library, a structured cost database is constructed. Using the constructed cost database, intelligent cost calculation is performed on new projects, achieving automated and intelligent calculation of development costs. This reduces the difficulty of cost calculation and improves calculation efficiency, while also laying the foundation for accurate business quotations.

[0009] To achieve the above objectives, the present invention provides the following technical solution:

[0010] In a first aspect, the present invention provides a method for calculating the development cost of automotive aftermarket technical data deliverables, comprising the following steps:

[0013] By combining the quota man-hour information of the corresponding cost feature combination retrieved from the development cost quota database, the development cost of the target deliverable is automatically calculated.

[0014] As a further aspect of the present invention, the cost account database is used to store the names of each cost account and their corresponding hierarchical relationships according to the type of deliverable, as well as the brand information applicable to the cost account. The construction steps of the cost account database include:

[0018] Based on the correspondence between development stages and work categories, establish the hierarchical relationship between the primary cost accounts, secondary cost accounts, and tertiary cost accounts, and mark the brand information applicable to the cost accounts;

[0019] Among them, the correspondence between secondary cost items and development stages, and between tertiary cost items and work categories, are all one-to-many relationships.

[0020] As a further aspect of the present invention, the cost feature database is associated with the cost item database and is used to store information on third-level cost items and their included task unit categories, as well as cost feature information affecting the task unit categories; the construction steps of the cost feature database include:

[0021] Based on the work step information in the associated development route element library, create the corresponding task unit category under the third-level cost account;

[0022] Based on the brand, deliverable category, development stage, task category, development route element factors and element characteristics information in the development route element library, cost element factors and element characteristics that affect the development cost of the task unit category are created.

[0023] As a further aspect of the present invention, the development cost quota database is associated with the cost characteristic database and is used to store task unit categories under the three-level cost accounts, different combinations of cost element factors and element characteristics, as well as corresponding job positions and quota working hours information; the construction steps of the development cost quota database include:

[0024] Combine the cost element factors and element characteristics of the task unit categories under the third-level cost account and set cost characteristic combination codes;

[0025] Estimate the cost by manually measuring or by using similar task unit categories under the same historical deliverables. Input the job level and quota hours information of different task units into the development cost quota database and mark the source of the quota hours information.

[0026] As a further aspect of the present invention, before calculating the development cost of the target deliverable, a development task assessment is also included, which comprises the following steps:

[0027] Build a development task database to store the development roadmap of historically developed deliverables and the development tasks and quantities contained under the task unit categories;

[0028] The system receives reference materials from the business quotation stage of the target deliverable and recommends historical development tasks and quantities similar to the target deliverable from the development task database based on pre-set development task recommendation rules for development cost calculation.

[0029] As a further aspect of the present invention, the preset development task recommendation rule is a multi-level matching rule, including:

[0030] First-level matching: Based on the reference materials of the target deliverable, calculate the similarity with the development standard elements of historical deliverables, and output the historical reference deliverables with a similarity higher than the set threshold.

[0031] Second-level matching: Based on the set of feature elements of the development route determined for the target deliverable, the similarity is calculated with the set of feature elements of historical reference deliverables output by the first-level matching, and a preset number of reference models are output.

[0032] Third-level matching: Based on the vehicle configuration information of the target deliverable, the similarity is calculated with the configuration information of the reference vehicle output by the second-level matching, and the development route and development task information of the historical vehicle with the highest similarity are output.

[0033] As a further aspect of the present invention, the development task evaluation also includes the following steps:

[0034] The development stage and task category information in the development roadmap of the created target deliverable are compared with the development roadmap and development task information of the historical vehicle models output by the third-level matching.

[0035] For those that can be matched, the corresponding development tasks and their quantities are retrieved from the development task database; for those that cannot be matched, the development quantity is estimated manually.

[0036] As a further aspect of the present invention, calculating the development cost of the target deliverable includes the following steps:

[0037] Based on the development roadmap of the target deliverables, automatically retrieve the corresponding cost item information from the cost item database;

[0038] Based on the cost item information and development roadmap element characteristic information, a combination of system recommendation and manual confirmation is used to determine cost element factors and element characteristic combinations for each task unit category.

[0039] Based on the determined task unit category and its cost element factors and element characteristics combination, the corresponding standard operation position and quota working hour information are automatically retrieved from the development cost quota database.

[0040] Based on the number of development tasks determined by each task unit category, the system automatically calculates the development cost.

[0041] Secondly, the present invention also provides a system for calculating the development cost of automotive aftermarket technical data deliverables, including a cost database and a cost calculation module; the cost database includes:

[0042] A cost account database is used to store cost account information with hierarchical relationships according to the type of deliverable.

[0043] The cost characteristic database stores the task unit categories under cost items, as well as their corresponding cost element factors and element characteristics;

[0044] Develop a cost quota database to store standard operating positions and quota working hours information for task unit categories corresponding to different cost element factors and element characteristic combinations;

[0045] The cost calculation module is configured as follows:

[0046] Receive development roadmap information associated with the target deliverables;

[0047] The system automatically constructs corresponding cost item information and cost item hierarchy in the cost database; and automatically recommends cost feature information for each task unit category under the third-level item in the cost feature database.

[0048] By combining the quota man-hour information of the corresponding cost feature combination retrieved from the development cost quota database, the development cost of the target deliverable is automatically calculated.

[0049] As a further aspect of the present invention, the automotive aftermarket technical data deliverable development cost calculation system further includes:

[0050] A development task database is used to store the development path and development task information of historically developed deliverables;

[0051] A development repository is used to store various reference materials throughout the entire lifecycle of deliverable development.

[0052] The cost calculation module is further configured to: based on the received reference materials, and through preset similarity calculation and matching rules, recommend development tasks and quantities similar to the target deliverable from the development task database for cost calculation.

[0053] As a further aspect of the present invention, the cost accounts stored in the cost account database have a three-level hierarchical structure, including:

[0054] Primary cost categories are pre-defined based on activity costs, administrative costs, outsourcing costs, or auxiliary costs.

[0055] Secondary cost items are set up based on development stage information in the development route element library;

[0056] The three-level cost accounts are set up based on the work category information in the development route element library;

[0057] Among them, there is a one-to-many relationship between the secondary cost items and the development stage, and between the tertiary cost items and the operation category items.

[0058] As a further aspect of the present invention, the task unit category is created based on the work step information in the development route element library; the cost element factors and element characteristics are created based on the brand, deliverable category, development stage, work category, development route element factors and element characteristic information in the development route element library.

[0059] As a further aspect of the present invention, the cost calculation module is configured to recommend historical development tasks and their quantities from the development task database using the following multi-level matching rules:

[0060] First-level matching: Based on the reference materials of the target deliverable, calculate the similarity with the development standard elements of historical deliverables, and output the historical reference deliverables with a similarity higher than the set threshold.

[0061] Second-level matching: Based on the feature set of development route elements determined for the target deliverable, a similarity calculation is performed with the feature set of historical reference deliverables output by the first-level matching, and a reference vehicle model is output.

[0062] Third-level matching: Based on the vehicle configuration information of the target deliverable, the similarity is calculated with the configuration information of the reference vehicle output by the second-level matching, and the development route and development task information of the historical vehicle with the highest similarity are output.

[0063] As a further aspect of the present invention, the cost calculation module is further configured as follows:

[0064] The development stage and task category information in the development roadmap of the created target deliverable are compared with the development roadmap and development task information of the historical vehicle models output by the third-level matching.

[0065] For matching tasks, the corresponding development tasks and quantities are retrieved from the development task database; for unmatched tasks, a manual input interface is provided to receive the estimated development quantity.

[0066] Compared with existing technologies, the present invention provides a method and system for calculating the development cost of automotive aftermarket technical data deliverables. By constructing a structured cost database and integrating intelligent matching and recommendation rules, it achieves automation, standardization, and intelligence in development cost calculation. Compared with traditional methods that rely on manual experience, it has the following advantages:

[0067] 1. This invention utilizes a three-level intelligent recommendation rule in the task evaluation module. The system can automatically and quickly filter out the most similar reference deliverables and their development tasks from massive amounts of historical data, replacing the enormous workload of manual searching, comparison, and analysis, and greatly shortening the cost evaluation cycle. Based on the specific development path of the deliverable, the system automatically constructs cost items, determines cost feature combinations, and calls the corresponding standard time quotas for calculation, avoiding the subjectivity and arbitrariness of manual estimation, significantly improving calculation efficiency and accuracy, and reducing work difficulty and human error.

[0068] 2. This invention systematically collects, classifies, and structures scattered historical cost data, time quotas, and experience judgments through a cost database. By establishing a multi-level cost model based on deliverable type, development stage, work category, task unit, and cost characteristics, it achieves hierarchical decomposition and refined accounting of development costs, realizing the structured accumulation and refined management of cost data.

[0069] In summary, this invention systematically solves the problems of low efficiency, poor accuracy, reliance on individuals, and extensive management inherent in traditional manual calculation methods, providing an efficient, accurate, and reliable solution for calculating the development costs of automotive aftermarket technical data deliverables.

[0070] These or other aspects of the invention will become more apparent from the following description of embodiments. It should be understood that the foregoing general description and the following detailed description are exemplary and explanatory only, and are not intended to limit the invention. Attached Figure Description

[0071] To more clearly illustrate the technical solutions in the embodiments of the present invention, the accompanying drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. In the drawings:

[0072] Figure 1 This is a flowchart illustrating a method for calculating the development cost of automotive aftermarket technical data deliverables according to the present invention.

[0073] Figure 2 This is a flowchart of the construction and calculation phase in a method for calculating the development cost of automotive aftermarket technical data deliverables according to the present invention. Detailed Implementation

[0074] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0075] Unless otherwise expressly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "comprises" shall be understood to include the stated elements or components without excluding other elements or other components.

[0076] like Figure 1 and Figure 2 As shown, one embodiment of the present invention provides a method for calculating the development cost of automotive aftermarket technical data deliverables, including the following steps:

[0077] Step S10: Construct a structured cost database, which includes a cost item database, a cost characteristic database, and a development cost quota database.

[0078] In this embodiment, a structured cost database is constructed based on the associated development roadmap element library. The cost item database stores the names and corresponding hierarchical relationships of each cost item according to deliverable type, as well as the brand information applicable to each cost item. The construction steps of the cost item database include:

[0079] Step S101: Pre-set primary cost categories according to the statistical scope of activity cost, management cost, outsourced cost, and auxiliary cost;

[0080] Step S102: Set up secondary cost items based on the development stage information in the associated development route element library;

[0081] Step S103: Set up three-level cost accounts based on the work category information in the development route element library;

[0082] Step S104: Establish the hierarchical relationship between the first-level cost account, second-level cost account, and third-level cost account according to the correspondence between development stage and work category, and mark the brand information applicable to the cost account;

[0083] In this embodiment, a cost account database is created according to the type of deliverable to store the name of each cost account, its corresponding hierarchical relationship, and the brand information applicable to each cost account. Specifically, information is extracted from the development route element library for each deliverable type, including development stage, work category, work steps, development route element factors, and element characteristics. First-level cost accounts are preset in the cost account database according to definitions such as activity cost, management cost, outsourcing cost, and auxiliary cost. Second-level cost accounts are set based on the development stage information in the development route element library. Third-level cost accounts are set based on the work category information in the development route element library. A hierarchical relationship between first-, second-, and third-level accounts is established according to the correspondence between development stages and work categories, and the brand information applicable to each cost account is marked.

[0084] Among them, the correspondence between secondary cost items and development stages, and between tertiary cost items and work categories, is a one-to-many relationship, that is, one secondary cost item corresponds to one or more development stages, and the same applies to tertiary items.

[0085] For example, if the deliverable type is user manual and the next level category is activity cost, and the development stage in the development route element library is content development and the activity category is classical Chinese development, then the corresponding second-level category can be set as content development; the third-level category can be set as classical Chinese development.

[0086] In this embodiment, the cost feature database is associated with the cost item database and is used to store information on third-level cost items and their included task unit categories, as well as cost feature information affecting the task unit categories; the construction steps of the cost feature database include:

[0087] Step S111: Based on the work step information in the associated development route element library, create the corresponding task unit category under the third-level cost account;

[0088] Step S112: Based on the brand, deliverable category, development stage, task category, development route element factors and element characteristics information in the development route element library, create cost element factors and element characteristics that affect the development cost of the task unit category.

[0089] In this embodiment, the constructed cost feature database is used to store three-level cost items and their included task unit category information, as well as cost feature information affecting the task unit categories. Specifically, the work step information corresponding to the work category items in the development route element library is extracted. Based on the work step information, corresponding task unit category information is created for each three-level cost item. Based on the brand, deliverable category, development stage, work category, development route element factors, and element feature information in the development route element library, developers create cost element factors and element features affecting the development cost of the task unit categories in the cost feature database, thus completing the construction of the cost feature database.

[0090] For example, when developing a third-level subject using classical Chinese, the factors affecting development costs can be created as: development method, content format, etc. The corresponding feature can be set as:

[0091] When the cost factor is the development method, the factor characteristics can be set as: manual development or system-assisted development;

[0092] When cost element factors are in content form, element characteristics can be set as: text, image, and text.

[0093] When selecting cost element factors based on task unit category information, one or more can be selected; however, only one cost element feature can be selected from the corresponding cost element factors.

[0094] In this embodiment, the development cost quota database is associated with the cost characteristic database and is used to store task unit categories under the three-level cost accounts, different combinations of cost element factors and element characteristics, as well as corresponding job positions and quota working hours information; the construction steps of the development cost quota database include:

[0095] Step S121: Combine the cost element factors and element characteristics of the task unit categories under the third-level cost account and set cost characteristic combination codes;

[0096] Step S122: Estimate the cost by manual measurement or based on similar task unit categories under the same historical deliverables, input the job level and quota working hours information of different task units into the development cost quota database, and mark the source of quota working hours information.

[0097] In this embodiment, the created development cost quota database is used to store task unit categories under the third-level cost account, with different combinations of cost element factors and element characteristics, as well as corresponding job levels and quota working hours. Specifically, the cost element factors and element characteristics of task unit categories under the third-level cost account are combined and a cost characteristic combination code is set, meaning that different cost characteristic combinations have unique codes. By using manual measurement or estimation based on similar task unit categories under the same historical deliverables, the job level and quota working hours information of different task units are input into the development cost quota database, and the source of the quota working hours information is marked through measurement or estimation.

[0098] Step S20: Receive the development roadmap information associated with the target deliverable, automatically construct the corresponding cost item information and cost item hierarchy in the cost database; automatically recommend the cost feature information of each task unit category under the third-level item in the cost feature database; and automatically calculate the development cost of the target deliverable by combining the quota man-hour information of the corresponding cost feature combination retrieved from the development cost quota database.

[0099] Before calculating the development cost of the target deliverable in this step, a development task assessment is also included, which includes the following steps:

[0100] Step S201: Construct a development task database to store the development path of historically developed deliverables and the development tasks and quantity information contained under the task unit category;

[0101] Step S202: Receive reference materials from the business quotation stage of the target deliverable, and recommend historical development tasks and quantities similar to the target deliverable from the development task database according to the preset development task recommendation rules for development cost calculation.

[0102] During the development task evaluation, a development resource database is created to store various reference materials throughout the entire lifecycle of deliverable development, such as: Bill of Materials (BOM), vehicle configuration tables, vehicle electrical schematics, wiring harness diagrams, and DTC lists. The constructed development task database stores the development roadmap for developed deliverables, and the development tasks contained within each task unit category, i.e., task unit names and development quantities.

[0103] This includes creating a cost calculation module to calculate development costs based on deliverable reference materials. Within this module, development task recommendation rules are created to recommend development tasks similar to historical deliverables. These pre-defined development task recommendation rules are multi-level matching rules, including:

[0104] First-level matching: Based on the reference materials of the target deliverable, calculate the similarity with the development standard elements of historical deliverables, and output the historical reference deliverables with a similarity higher than the set threshold.

[0105] Second-level matching: Based on the set of feature elements of the development route determined for the target deliverable, the similarity is calculated with the set of feature elements of historical reference deliverables output by the first-level matching, and a preset number of reference models are output.

[0106] Third-level matching: Based on the vehicle configuration information of the target deliverable, the similarity is calculated with the configuration information of the reference vehicle output by the second-level matching, and the development route and development task information of the historical vehicle with the highest similarity are output.

[0107] In other words, the specific recommendation rules are as follows:

[0108] A. Based on the received reference materials, search for and calculate the similarity of standard elements in the development route element library, and output a quantitative (tentatively set at 20) historical reference deliverables that are greater than the set threshold (similarity greater than 60%).

[0109] B. Based on the received reference materials, select the development route element factors and element features of the target deliverable in the development route element library. Calculate the similarity between the selected element factors and element features and the reference deliverable from step A, and output a preset number of reference vehicle models.

[0110] C. Based on the configuration information of the new project vehicle model, calculate the similarity with the configuration information of the historical reference vehicle model output in step B, and output the development roadmap and development task information of the vehicle model with the highest similarity.

[0111] The similarity calculation methods for standard elements, development route element feature sets, and vehicle configurations are as follows, taking the calculation of standard element similarity as an example (the others are similar):

[0112] Standard feature similarity = Number of development standard feature features that are the same between the target deliverable and historical deliverables / Total number of development standard feature features of the target deliverable * 100%.

[0113] In this embodiment, the development task evaluation further includes the following steps:

[0114] The development stage and task category information in the development roadmap of the created target deliverable are compared with the development roadmap and development task information of the historical vehicle models output by the third-level matching.

[0115] For those that can be matched, the corresponding development tasks and their quantities are retrieved from the development task database; for those that cannot be matched, the development quantity is estimated manually.

[0116] In this embodiment, calculating the development cost of the target deliverable includes the following steps:

[0117] Step S211: Based on the development roadmap of the target deliverable, automatically retrieve the corresponding cost item information from the cost item database;

[0118] Step S212: Based on the cost item information and development route element characteristic information, a combination of system recommendation and manual confirmation is used to determine the cost element factors and element characteristic combinations for each task unit category.

[0119] Step S213: Based on the determined task unit category and its cost element factors and element feature combination, automatically retrieve the corresponding standard operation position and quota working hour information from the development cost quota database, wherein the operation position is matched with the corresponding labor cost.

[0120] Step S214: Based on the number of development tasks determined by each task unit category, automatically calculate the development cost.

[0121] In this step, when calculating development costs, the development cost = the corresponding human resource cost for operational positions * the number of development tasks * the standard working hours.

[0122] When calculating the development cost of the target deliverable, the set of development stage and task category information from the target deliverable development routes already created in the development route element library is compared with the deliverables already recommended in C. For those that match, the corresponding development tasks are retrieved from the development task database; for those that do not match, the number of task units to be developed is estimated manually.

[0123] When automatically calculating development costs, the cost calculation module automatically retrieves the corresponding cost item information from the cost item database based on the target deliverable development route already created in the development route element library. Based on the cost item information and development route element feature information, and using a combination of system recommendations and manual selection, the cost calculation module automatically receives the cost element factors and element feature combinations for each task unit category under the target deliverable's third-level cost item, output from the cost feature database.

[0124] Based on the cost element factors and element characteristics corresponding to the task unit category, the cost calculation module automatically retrieves the corresponding task unit category, standard operation position of the task unit category, and quota working hours information from the development cost quota database.

[0125] Based on the development tasks created in the development task assessment, as well as information such as the corresponding task unit category, job positions, and quota work hours, the cost calculation module automatically calculates the development cost of the target deliverable.

[0126] The automotive aftermarket technical data deliverable development cost calculation method of this invention, through the three-level intelligent recommendation rules of the development task evaluation module, can automatically and quickly filter out the most similar reference deliverables and their development tasks from massive historical data, replacing the huge workload of manual searching, comparison and analysis, and greatly shortening the cost evaluation cycle; according to the specific development route of the deliverable, it automatically constructs cost items, determines cost feature combinations and calls the corresponding standard time quotas for calculation, avoiding the subjectivity and arbitrariness of manual estimation, greatly improving the calculation efficiency and accuracy, and reducing the difficulty of work and human error.

[0127] This invention systematically collects, classifies, and structures scattered historical cost data, time quotas, and experience judgments through a cost database. By establishing a multi-level cost model based on deliverable type, development stage, work category, task unit, and cost characteristics, it achieves step-by-step decomposition and refined accounting of development costs, realizing the structured accumulation and refined management of cost data.

[0128] See Figure 1 and Figure 2 As shown, another embodiment of the present invention also provides a system for calculating the development cost of automotive aftermarket technical data deliverables. This system includes a cost database and a cost calculation module; the cost database includes:

[0129] A cost account database is used to store cost account information with hierarchical relationships according to the type of deliverable.

[0130] The cost characteristic database stores the task unit categories under cost items, as well as their corresponding cost element factors and element characteristics;

[0131] Develop a cost quota database to store standard operating positions and quota working hours information for task unit categories corresponding to different cost element factors and element characteristic combinations;

[0132] The cost calculation module is configured as follows:

[0133] Receive development roadmap information associated with the target deliverables;

[0134] The system automatically constructs corresponding cost item information and cost item hierarchy in the cost database; and automatically recommends cost feature information for each task unit category under the third-level item in the cost feature database.

[0135] By combining the quota man-hour information of the corresponding cost feature combination retrieved from the development cost quota database, the development cost of the target deliverable is automatically calculated.

[0136] In this embodiment, the automotive aftermarket technical data deliverable development cost calculation system further includes:

[0137] A development task database is used to store the development path and development task information of historically developed deliverables;

[0138] A development repository is used to store various reference materials throughout the entire lifecycle of deliverable development.

[0139] The cost calculation module is further configured to: based on the received reference materials, and through preset similarity calculation and matching rules, recommend development tasks and quantities similar to the target deliverable from the development task database for cost calculation.

[0140] The cost accounts stored in the cost account database have a three-level hierarchical structure, including:

[0141] Primary cost categories are pre-defined based on activity costs, administrative costs, outsourcing costs, or auxiliary costs.

[0142] Secondary cost items are set up based on development stage information in the development route element library;

[0143] The three-level cost accounts are set up based on the task category information in the development route element library.

[0144] Among them, there is a one-to-many relationship between the secondary cost items and the development stage, and between the tertiary cost items and the operation category items.

[0145] The task unit category is created based on the work step information in the development route element library; the cost element factors and element characteristics are created based on the brand, deliverable category, development stage, work category, development route element factors and element characteristic information in the development route element library.

[0146] In this embodiment, the cost calculation module is configured to recommend historical development tasks and their quantities from the development task database using the following multi-level matching rules:

[0147] First-level matching: Based on the reference materials of the target deliverable, calculate the similarity with the development standard elements of historical deliverables, and output the historical reference deliverables with a similarity higher than the set threshold.

[0148] Second-level matching: Based on the feature set of development route elements determined for the target deliverable, a similarity calculation is performed with the feature set of historical reference deliverables output by the first-level matching, and a reference vehicle model is output.

[0149] Third-level matching: Based on the vehicle configuration information of the target deliverable, the similarity is calculated with the configuration information of the reference vehicle output by the second-level matching, and the development route and development task information of the historical vehicle with the highest similarity are output.

[0150] In this embodiment, the cost calculation module is further configured as follows:

[0151] The development stage and task category information in the development roadmap of the created target deliverable are compared with the development roadmap and development task information of the historical vehicle models output by the third-level matching.
