Description

Technical Field

[0001] The present invention belongs to the technical field of aero-engine technical standard management, and particularly relates to a method and system for evaluating the standard access of an aero-engine R & D system. Background Art

[0002] There are many existing aero-engine standards, including both foreign and domestic standards. During the development process of aero-engine models, the selection of standards for a model is essentially a screening and access to the existing standard resources. Only the standards that meet the conditions of being currently valid and in line with the requirements of model development can be included in the model selection standard catalog, and after being verified by multiple models, they are incorporated into the R & D system as the standard selection recommendations for subsequent model applications.

[0003] Affected by the technical content relied on during standard compilation and the standard compilation team (including standard compilers and standard review experts), the currently released standards have uneven levels. Moreover, affected by the unsmooth transmission of standard information and different technical content platforms relied on by the standards, there are multiple similar standards for the same matter that are simultaneously valid, and analysis and selection are required during actual use. The existing standard technical level is difficult to fully meet the requirements of R & D system construction.

[0004] For existing standard projects, due to the limitation of the technical content relied on during standard compilation, when the corresponding technical basis changes, the corresponding standard projects are no longer applicable. For example, for the change management requirements based on the original paper management mode, redrafting or base map changes are required, but in the case of widespread use of the PDM system for electronic data management, this requirement is actually rarely used.

[0005] For the standard projects that are being compiled or have been released, the main technical content relies on relevant standard materials or the latest technological development direction, and the leading standard projects formulated, that is, the standard projects that have not been fully verified and applied, need to analyze and confirm the applicability of the above standard projects during R & D system construction.

[0006] Due to historical reasons such as standard management reform, there are situations where the existing standard projects have duplicate numbers, similar or contradictory contents, such as GJB 4187 - 2001 "Requirements for Aero-Engine Ice-Ingestion Test" and GJB 5032 - 2001 "Requirements for Aero-Engine Ice-Ingestion Test", GJB 4879 - 2003 "Requirements for High-Altitude Simulation Test of Aero-Turbojet and Turbo-Fan Engines" and GJB 5028 - 2001 "Requirements for High-Altitude Simulation Test of Aero-Turbojet and Turbo-Fan Engines", etc. For the above standards, during R & D system construction, their applicability needs to be analyzed and confirmed.

[0007] However, in the process of forming a selection standard catalog for existing aero-engine models, mostly rough screening is carried out, and the applicability of the standards cannot be evaluated finely. There are also information barriers in the standard application situations among various models, which is not conducive to the construction and application of the aero-engine R & D system standards. Summary of the Invention

[0008] In view of the above problems, the present invention provides a standard access evaluation method and system for an aero-engine R & D system, adopting the following technical solutions:

[0009] A standard access evaluation method for an aero-engine R & D system includes the following steps:

[0010] Collect aero-engine standards;

[0011] Determine the model standard requirements according to the R & D requirements and technical solutions of the aero-engine model;

[0012] Screen the collected aero-engine standards according to the model standard requirements and the first evaluation indicators to obtain a model selection standard catalog;

[0013] During the process of aero-engine model development activities, apply the corresponding standards in the model selection standard catalog and collect the feedback data of the standard application;

[0014] Preprocess the feedback data of the standard application, output a standard application feedback report, re-evaluate the standards according to the second evaluation indicators and the standard application feedback report, determine the standard access result, and output a model adoption standard catalog;

[0015] Integrate and process the model adoption standard catalog, obtain the standard collection adopted by each model, and output the aero-engine R & D system standard catalog;

[0016] During the set time, conduct a review and evaluation of the standards in the R & D system catalog using the third evaluation indicators, and update the R & D system standard catalog according to the evaluation results.

[0017] Furthermore, the first evaluation indicators include necessity, compliance, and coordination. Compliance includes procedural compliance, intellectual property compliance, and version effectiveness. Coordination includes coordination with current laws and regulations and coordination with standards;

[0018] Among them, necessity is used to evaluate the importance of the standard and determine whether the standard enters the model selection standard catalog. Procedural compliance is used to evaluate whether the standard source channel meets the requirements. Intellectual property compliance is used to evaluate whether the implementation of the standard will infringe on the rights of the intellectual property owner. Version effectiveness is used to evaluate whether the standard version is valid;

[0019] The coordination with current laws and regulations is used to evaluate whether the standards comply with laws and regulations, and the coordination with standards is used to evaluate whether there are any contradictions or incompatibilities between the standards and other standards in the aircraft engine system.

[0020] Furthermore, the feedback data of the standard application is preprocessed, including the following steps:

[0021] By summarizing and processing the feedback data on standard application, screening effective opinions, merging similar opinions, classifying the feedback data on standard application, and outputting a standard application feedback report.

[0022] Further, the standard is evaluated according to the second evaluation index and the standard application feedback report, the standard access result is determined, and the output model adopts the standard catalog, including the following steps:

[0023] Determine the score of each sub-indicator in the second evaluation indicator. According to the standard application feedback report, determine the score of each sub-indicator of the standard in the second evaluation indicator. Sum the scores of the standard in each sub-indicator to obtain the standard access evaluation score. If the standard access evaluation score is greater than the threshold score value, determine the standard access and include the standard in the model adoption standard catalog.

[0024] Furthermore, the sub-indicators of the second evaluation indicator include maturity, advancement, practicality and cost-effectiveness.

[0025] Furthermore, maturity includes standard maturity and standard implementation conditions. Standard maturity is used to evaluate whether the standard has been verified by engineering application and the effectiveness of application verification. Standard implementation conditions are used to evaluate the technical reserves and industrial infrastructure conditions required for standard implementation.

[0026] Furthermore, the practicality of product standards includes completeness, rationality and sufficiency. Completeness is used to evaluate whether the product requirements contained in the standard are complete, rationality is used to evaluate whether the requirements and indicators of the standard are reasonable, and sufficiency is used to evaluate whether the verification requirements of the product requirements are complete;

[0027] The practicality of requirement standards includes clarity, feasibility and continuity. Clarity is used to evaluate whether the requirements are clear and unambiguous, feasibility is used to evaluate whether the requirements are feasible and verifiable, and continuity is used to evaluate whether the requirements fully cover the upper-level requirements.

[0028] The practicality of method standards includes method feasibility and detail. Method feasibility is used to evaluate whether the specified methods, processes, procedures, etc. are applicable, and detail is used to evaluate whether the standards are accurate and complete in compiling methods, processes, and procedures.

[0029] Further, the third evaluation index includes necessity, compliance, coordination, maturity, advancement, practicability, and cost-effectiveness.

[0030] The present invention also provides an aviation engine R & D system standard access evaluation system, including:

[0039] Determining the scores of each sub-index in the second evaluation index, determining the scores of the standards in each sub-index in the second evaluation index according to the feedback report on the application of the standards, summing up the scores of the standards in each sub-index to obtain the access evaluation score of the standards. If the access evaluation score of the standards is greater than the threshold score value, it is determined that the standards are accessible, and the standards are incorporated into the model adoption standard catalog.

[0040] The beneficial effects of the present invention:

According to the model standard requirements and the first evaluation index, the present invention screens the collected aero-engine standards to obtain a model selection standard catalog, and completes the Class I standard access evaluation; according to the second evaluation index and the standard application feedback report, the standards are re-evaluated to determine the standard access result, and the model adoption standard catalog is output to complete the Class II standard access evaluation; within the set time, the third evaluation index is used to conduct a review evaluation on the standards in the R & D system catalog, and the R & D system standard catalog is updated according to the evaluation results to complete the Class III standard access evaluation; the present invention realizes the selection standard evaluation by category (3 categories) and in stages, which can effectively ensure the standard access effect in each stage of the aero-engine R & D system.

[0049] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the protection scope of the present invention.

[0050] It should be noted that the terms "first", "second", etc. in this application are used to distinguish similar objects and do not necessarily describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances for the embodiments of the present application described herein.

[0051] The present invention provides a method and system for evaluating the standard access of an aero-engine R & D system, clarifies the model selection catalog of aero-engines, the adopted standards, and the timing of evaluating the standard access of the R & D system selection criteria, proposes standard access evaluation indicators, and can ensure the integrity, rationality, and operability of the aero-engine R & D system standards, and ensure the supporting role of the standards in the construction and application process of the R & D system.

[0052] As Figure 1 and Figure 3 shown, a method for evaluating the standard access of an aero-engine R & D system includes the following steps:

[0053] S1. Collect aero-engine standards and output a detailed list of aero-engine standards, specifically including: collecting aero-engine standards within the target area, including foreign standards, national standards, industry standards, and enterprise standards.

[0054] This step collects the mastered aero-engine standards within the target area to provide data support for model development and R & D system construction.

[0055] S2. Determine the model standard requirements according to the R & D requirements and technical solutions of the aero-engine model, and output a model standard requirements analysis report.

[0056] This step aims to meet the standard requirements for the entire process of R & D of model products, and sort out the standard requirements according to the main line of the R & D process, including design, materials, manufacturing, testing, service support, project management, etc. The model standard requirements include the requirements for the R & D process activities themselves and their associated standard requirements.

[0057] S3. Screen the collected aero-engine standards according to the model standard requirements and the first evaluation indicators to obtain a model selection standard catalog and complete the evaluation of Class I standard access.

[0058] The preliminary selection of access standards in this step can replace the standard applicability analysis work in the model standardization work. By combining the model standard requirements, the scope of the model selection standards is initially locked, and the necessity, compliance and coordination of the standards are evaluated according to the standard access evaluation index system. After obtaining the model selection standard catalog, it can be used for standard selection and implementation in the model development process.

[0059] The collected aircraft engine standards are screened according to the model standard requirements and the first evaluation index to obtain a model selection standard catalog, including the following steps: preliminarily screening the collected aircraft engine standards according to the model standard requirements to obtain a standard set; based on the first evaluation index, screening out standards that meet the first evaluation index from the standard set to obtain a model selection standard catalog.

[0060] Generally speaking, if the standard in the standard set meets the first evaluation indicator, the standard will be selected into the model selection standard catalog. If the standard cannot meet the first evaluation indicator, there is no need for subsequent evaluation, and the standard evaluation conclusion should be that it is not allowed to enter and will not be selected into the model selection standard catalog. In special circumstances, if the standard does not meet the first evaluation indicator but is of great value to the model development, it can be included in the system as an exception, but the standard status such as "limited use" or "reference" needs to be indicated.

[0061] For example, the first evaluation index includes necessity, compliance and coordination, all of which are switch-type indicators.

[0062] Among them, necessity is used to evaluate the importance of the standard and determine whether the standard should be included in the model selection standard catalog. If the scope and applicable objects of the standard are consistent with the needs and the standard is irreplaceable, or the scope and applicable objects of the standard are consistent with the needs and there are similar standards, but the existing similar standards cannot meet the usage requirements under the set conditions, then it is determined that the standard meets the necessity; if the existing standards can completely replace the evaluation standards, or the scope and applicable objects of the standards do not meet the needs, then it is determined that the standard does not meet the necessity.

[0063] For example, compliance includes procedural compliance, intellectual property compliance and version validity. Procedural compliance is used to evaluate whether the source of the standard channel meets the requirements. If the standard is an officially released standard, it is determined that the procedural compliance is met. If the standard has not completed the entire release process, it is determined that the procedural compliance is not met.

[0064] Intellectual property compliance is used to evaluate whether the implementation of the standard will infringe the rights of the intellectual property owner. If the standard does not involve trade secrets, patents and software copyrights, or does not infringe on the right to use patents and software copyrights that have been obtained, then it is determined that intellectual property compliance is met; if the implementation of the standard involves the risk of infringing patents or software copyrights, then it is determined that intellectual property compliance is not met.

[0065] The version validity is used to evaluate whether the standard version is valid. If the standard is the current latest valid version, or the standard is an old version that is clearly not adopted in the model, or the standard whose invalidation is not clearly stated, or the standard that has been invalidated but there is no alternative version yet, then it is determined to meet the version validity; if the standard is a version that has been clearly invalidated and there is an alternative standard, then it is determined not to meet the version validity.

[0066] The coordination includes the coordination with current laws and regulations and the coordination with standards. Among them, the coordination with current laws and regulations is used to evaluate whether the standard complies with laws and regulations, and the coordination with standards is used to evaluate whether there are contradictions or incompatibilities between the standard and other standards within the aero-engine system.

[0067] If the standard complies with current laws and regulations, it is determined to meet the coordination with current laws and regulations; if it violates current laws and regulations, it is determined not to meet the coordination with current laws and regulations.

[0068] If the standard can be used in conjunction with top-level, upper-level, and lower-level standards, and there are no obvious contradictions or incompatibilities with other standards, it is determined to meet the coordination with standards; if there are inconsistencies or contradictions in requirements, indicators, etc. between the standard and some standards within the system, it is determined not to meet the coordination with standards.

[0069] S4. During the process of model development activities of aero-engines, apply the corresponding standards in the model selection standard catalog, collect the feedback data on the application of the standards, and output the standard feedback opinion record form, specifically as follows:

[0070] According to the model selection standard catalog, implement the corresponding standards in model development, complete the practical operation and application of the standards, collect the feedback data on the application of the standards, record the opinions and suggestions of the standard users (i.e., the front-line R & D personnel in the model development of aero-engines), and output the standard feedback opinion record form.

[0071] S5. Preprocess the feedback data on the application of the standards, output the standard application feedback report, re-evaluate the standards based on the second evaluation index and the standard application feedback report, determine the standard access result, output the model adoption standard catalog, and complete the Class II standard access evaluation.

[0072] Among them, the preprocessing of the feedback data on the application of the standards includes the following steps: through the summary processing of the feedback data on the application of the standards, screening out valid opinions, merging similar opinions, classifying the feedback data on the application of the standards, and outputting the standard application feedback report to provide data support for the evaluation of the access standards application.

[0073] The standard application feedback data is reported by each model development unit. Due to the large amount of information, there may be problems such as confusion and duplication in opinions. Effective opinions should be screened out, and the opinions with clear expressions, clear logic, and clear standard positions should be selected as effective opinions; the effective opinions should be merged, and the same or similar opinions should be integrated to reduce duplicate opinions; the feedback opinions are usually mainly related to the practicality of the standard. It is still necessary to classify the effective and integrated opinions according to the types such as the accuracy, operability, and integrity of the standard, and classify the standard feedback problems to form a standard application feedback report.

[0074] Evaluate the standard according to the second evaluation index and the standard application feedback report, determine the standard access result, and output the standard catalog adopted by the model, including the following steps:

[0075] Determine the scores of each sub-index in the second evaluation index. According to the standard application feedback report, determine the scores of the standard in each sub-index of the second evaluation index, sum up the scores of the standard in each sub-index to obtain the access evaluation score of the standard. If the access evaluation score of the standard is greater than the threshold score value, determine that the standard is approved and include the standard in the standard catalog adopted by the model.

[0076] For example, the sub-indexes of the second evaluation index include maturity, advancement, practicality, and cost-effectiveness. Among them, the key factors affecting whether the standard is easy to use are maturity and practicality. High scores in these two indicators indicate strong implementability and guiding value of the standard. Therefore, the weights of these two indicators, maturity and practicality, should be appropriately increased in the second evaluation index.

[0077] For example, the total score of the second evaluation index is 100 points, the scores of maturity and practicality are 30 points, and the scores of advancement and cost-effectiveness are 20 points. The full score of the access evaluation score of the standard is 100. 100 - 90 points is excellent, 90 - 70 points is qualified, less than 70 points is unqualified, and the threshold score value is 70.

[0078] For example, maturity includes standard maturity and standard implementation conditions. Standard maturity is used to evaluate whether the standard has been verified by engineering applications and the effect of the application verification. For example, determining the scores of standard maturity includes:

[0079] If all the clauses of the standard have passed engineering application verification and all the standard clauses are clear after verification, and there are no disagreement items in the implementation process of aero-engine development, the score is 16 - 20 points.

[0080] If more than 90% (including 90%) of the clauses of the standard have passed engineering application verification, and after verification, the number of disagreement items of some standard requirements in the implementation process of aero-engine development is less than the set value, the score is 11 - 15 points.

[0081] If more than 50% (inclusive) but less than 89% of the standard clauses are verified through engineering applications, and the number of controversial items during the implementation process of aero-engine development is less than the set value, the score will be 6 - 10 points.

[0082] If more than 50% of the standard clauses have not been verified through engineering applications, or the number of controversial items during the implementation process of aero-engine development is greater than the set value, the score will be 1 - 5 points.

[0083] The standard implementation conditions are used to evaluate the technical reserves and industrial infrastructure conditions required for standard implementation. For example, the score determination for standard implementation conditions includes:

[0084] If all the technical reserves and industrial infrastructure conditions (such as equipment, materials, processes, basic components, standard parts, etc.) required for standard clause implementation are fully available, the score will be 7 - 10 points.

[0085] If the key clauses of the standard have relevant technical reserves and industrial infrastructure conditions (such as equipment, materials, processes, basic components, standard parts, etc.), the score will be 4 - 6 points.

[0086] If the basic reserves and industrial infrastructure conditions (such as equipment, materials, processes, basic components, standard parts, etc.) of some key clauses of the standard do not meet the requirements, the score will be 0 - 3 points.

[0087] Advancement is used to evaluate the level of technical requirements and indicators of the standard. For example, the score determination for the advancement of the standard includes:

[0088] If more than 95% of the technical requirements or indicators reach the level of existing valid similar standards, or there are no similar standards, and the technical requirements or indicators can meet the development needs of advanced main battle equipment, the score will be 15 - 20 points.

[0089] If more than 50% of the technical requirements or indicators reach the level of existing valid similar standards, or there are no similar standards for reference, and the technical requirements or indicators can meet the development needs of domestic advanced main battle equipment, the score will be 10 - 14 points.

[0090] If more than 50% of the technical requirements or indicators are lower than the level of existing valid similar standards, or there are no similar standards for reference, and the technical requirements or indicators cannot meet the development needs of advanced main battle equipment, the score will be 5 - 9 points. If the level of technical requirements or indicators can only meet the needs of old - model equipment, the score will be 0 - 4 points.

[0091] The practicality of product - type standards includes integrity, rationality, and sufficiency. Integrity is used to evaluate whether the product requirements included in the standard are complete. The score determination for the integrity of the standard includes:

[0092] If the standard fully covers the product requirements and can provide comprehensive constraints for product development, the score is 7 - 10 points. If there are less than 5% of the missing items in the product requirements of the standard and it can provide constraints for the key areas of product development, the score is 4 - 6 points. If there are obvious missing items in the standard and it cannot effectively control product development, the score is 0 - 3 points.

[0093] The rationality is used to evaluate whether the requirements and indicators of the standard are reasonable. The scores for determining the rationality of the standard include:

[0094] If during the implementation process of aero-engine development, 100% of the requirements and indicators of the standard are reasonable, the score is 7 - 10 points; if more than 90% of the requirements and indicators are reasonable, the score is 4 - 6 points. If there are multiple unreasonable requirements or indicators, the score is 0 - 3 points.

[0095] The sufficiency is used to evaluate whether the verification requirements for product requirements in the standard are complete. The sufficiency of the standard is determined as follows: If the requirements of the standard are related to the verification of the aero-engine as a whole, components, and systems, and the verification methods and requirements are reasonable, the score is 7 - 10 points. If the requirements of the standard are related to some of the content in the verification of the aero-engine as a whole, components, and systems, and the verification methods and requirements are reasonable, the score is 4 - 6 points. If the requirements of the standard are not related to the verification of the aero-engine as a whole, components, and systems, and the verification methods and requirements are reasonable, the score is 0 - 3 points.

[0096] The practicability of requirement-based standards includes clarity, requirement feasibility, and inheritance. Clarity is used to evaluate whether the proposed requirements are clear and unambiguous. The scores for determining the clarity of the standard include:

[0097] If the requirements proposed by the standard are clear and unambiguous, the score is 7 - 10 points. If more than 90% of the requirements of the standard are clear and unambiguous, the score is 4 - 6 points. If there are multiple (more than 10%) unclear or ambiguous requirements in the standard, the score is 0 - 3 points.

[0098] Requirement feasibility is used to evaluate whether the proposed requirements are feasible and verifiable. The scores for determining requirement feasibility include: If the requirements proposed by the standard are feasible and can all be verified, the score is 7 - 10 points. If 90% of the requirements proposed by the standard are feasible and can be verified, the score is 4 - 6 points. If there are multiple (more than 10%) requirements in the standard that cannot be implemented or cannot be directly verified, the score is 0 - 3 points.

[0099] Inheritance is used to evaluate whether the proposed requirements fully cover the upper-level requirements and whether they are coordinated. The scores for determining the inheritance of the standard include:

[0100] If the requirements proposed by the standard can completely cover the main upper-level requirements and the content is coordinated, the score is 7-10 points. If the requirements proposed by the standard can basically cover (more than 90%) the key upper-level requirements and the content is basically coordinated, the score is 4-6 points. If there are missing upper-level requirements in the standard, or there are contradictions or disharmonies with the upper-level requirements, the score is 0-3 points.

[0101] The practicability of method-type standards includes method feasibility and detail. Method feasibility is used to evaluate whether the specified methods, processes, procedures, etc. can be applied. The scores for determining the method feasibility of the standard include:

[0102] If the methods, processes, and procedures proposed by the standard are clearly expressed, logically reasonable, and can be fully applied in the model, the score is 10-15 points. If the methods, processes, and procedures proposed by the standard are clearly expressed, logically reasonable, and the key content can be applied in the model, the score is 5-9 points. If the methods, processes, and procedures proposed by the standard cannot be directly applied in the model, the score is 0-4 points.

[0103] Detail is used to evaluate whether the preparation of the methods, processes, and procedures in the standard is accurate and complete. The scores for determining the detail of the standard include:

[0104] If the methods, processes, and procedures proposed by the standard can provide accurate, detailed, and practical guiding information for model application, the score is 10-15 points. If the methods, processes, and procedures proposed by the standard can partially provide accurate, detailed, and practical guiding information for model application, the score is 5-9 points. If the methods, processes, and procedures proposed by the standard cannot provide guiding information, or the content is incomplete and difficult to be directly applied in the model, the score is 0-4 points.

[0105] The practicability of operation-type standards includes operability. Operability is used to evaluate whether the standard can be directly used for actual operations. The scores for determining the operability of the standard include:

[0106] If the rules and processes proposed by the standard are clearly expressed, the content is accurate, and it is operable and can be directly applied in the model, the score is 20-30 points. If the rules and processes proposed by the standard are clearly expressed, the content is accurate, and some content is operable and can be directly applied in the model, the score is 10-19 points. If the rules and processes proposed by the standard are not operable and cannot be directly applied in the model, the score is 0-9 points.

[0107] The cost-effectiveness ratio is used to evaluate the relationship between the economic / social benefits generated after the implementation and implementation of the standard and the increase in time / economic costs. The scores for determining the cost-effectiveness ratio of the standard include:

[0108] If the standard's economic value reaches the first set value, has social value, and does not increase costs, the score is 12 - 20 points. If the standard's economic value is less than the first set value, has social value, and the cost increase is less than the second set value, the score is 5 - 11 points. If the standard's economic value is less than the first set value, has social value, and the cost increase is greater than or equal to the second set value, the score is 0 - 4 points.

[0109] S6. Integrate and process the standards for each model using a standard catalog, obtain the standard set adopted by each model, and output the standard catalog of the aero - engine R & D system.

[0110] The formation of the R & D system standard catalog output in this step has undergone two evaluations, and can basically control the standard quality. Therefore, this process generally does not require additional review. By merging the standard catalogs adopted by each model of the aero - engine, the R & D system standard catalog can be formed.

[0114] This step conducts a review and evaluation of the standard application feedback report of the standards in the R & D system catalog. Newly released standards are considered for inclusion in the R & D system; standards that do not meet the requirements of the third evaluation index are deleted from the R & D system standard catalog or revised suggestions are given.

[0115] The aero - engine R & D system standard access evaluation method in the embodiments of the present invention divides the aero - engine R & D system standard access evaluation into 3 categories. The evaluation purposes, evaluation timings, and applicable evaluation indexes of the 3 - category evaluations are shown in Table 1. The 3 - category standard access evaluations correspond to different stages of the access evaluation, and the evaluation timings also reflect the work requirements of different stages, such as Figure 2 shown.

Model X; the Class III evaluation essentially provides support for the final confirmation and release of the R & D system standard, including step S7, which is summarized as the access standard release stage.

[0120] The embodiment of the present invention can realize the evaluation of the selection standard by category (3 categories) and in stages, which can effectively ensure the standard access effect in each stage of the aero-engine R & D system.

[0121] The first evaluation index, the second evaluation index, the third evaluation index and the evaluation form of the embodiment of the present invention can evaluate whether the standard accesses the aero-engine R & D system from multiple dimensions of qualitative and quantitative.

[0122] As shown in Table 2, the first evaluation index of the embodiment of the present invention is a switch-type index, the second evaluation index is a scoring-type index. The switch index includes necessity, compliance, and coordination, and the scoring index includes maturity, advancement, practicality, and cost-effectiveness. These indexes obtain the scores of each index through the scoring details.
