[0002] In nuclear power plant construction, the quality of nuclear-grade equipment directly affects the safe and stable operation of the reactor. The Quality Planning (QCP) is a core quality control document in the equipment manufacturing process, its core content being the establishment of reasonable control points for each manufacturing process. Whether the control points are set scientifically, reasonably, and comprehensively directly determines the effectiveness of quality supervision and the accuracy of resource allocation. Currently, control point work mainly relies on the supervision engineer's understanding of domestic and international standards and regulations, such as the American Society of Mechanical Engineers (ASME) and the National Standards of the People's Republic of China (GB), as well as management procedures. Due to the vast and frequently updated standard system, different engineers have different understandings of the same process, leading to room for optimization in the setting of control points for similar equipment in different projects, and even in different packages within the same project. Furthermore, the current method of setting control points mostly involves manual database queries, which is time-consuming, labor-intensive, and prone to errors, reducing the efficiency of control point management.

Optionally, the step of confirming the historical information of the control points based on the structured control point data, wherein the historical control point information includes the historical control point type corresponding to the structured control point data, includes: determining whether the standard control point type has a mandatory description; if the determination is negative, then obtaining historical biased control points and historical abnormal control points based on the historical control point information; confirming the weight of the historical biased control points based on the historical biased control points; confirming the weight of the historical abnormal control points based on the historical abnormal control points; and confirming the historical control point type based on the weight of the historical biased control points and the weight of the historical abnormal control points.

It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0018] This application refers to Figure 1 A manufacturing process control point selection method 10 (hereinafter referred to as "control point method 10") is proposed, which can intelligently select and set control points for manufacturing processes, further improving the effectiveness of reactor quality supervision. Flowcharts are used in this application to illustrate the operations performed by the system according to embodiments of this application. It should be understood that preceding or following operations are not necessarily performed precisely in sequence. Instead, various steps can be processed in reverse order or simultaneously. At the same time, other operations may be added to these processes, or one or more steps may be removed from these processes.

[0019] Specifically, refer to Figure 1The control point selection method 10 mainly includes steps S1-S4. Step S1 may include acquiring raw control point data and converting it into structured control point data. Step S2 may include confirming standardized control point information based on the structured control point data. Standardized control point information includes the standard control point type corresponding to the structured control point data. For example, standardized control point information can be obtained from a standard database, which mainly includes domestic and international standards and regulations, such as ASME and GB, for manufacturing processes. Step S3 may include confirming historical control point information based on the structured control point data. Historical control point information includes the historical control point type corresponding to the structured control point data. Historical control point information can be obtained from a historical database, which stores relevant information for all control point types corresponding to the manufacturing process. Step S4 may include confirming the control point selection decision based on the standard control point type and the historical control point type. By integrating standardized information from comprehensive control points with historical information from control points, a dual-driven mechanism is employed, combining standard specifications from the standard database with historical control point information from the historical database. This ensures both regulatory compliance (bottom-line thinking) and incorporates best engineering practices (optimization thinking). It effectively avoids the rigidity caused by relying solely on standards or the arbitrariness caused by relying solely on experience, further guaranteeing the accuracy and reliability of control points and thus improving the effectiveness of reactor quality supervision. In some embodiments, control point types may include one or any combination of shutdown inspection points (H points), witness points (W points), document review points (R points), and points not requiring supervision (N / A points).

[0020] The following details steps S1-S4. First, in step S1, raw control point data is acquired and converted into structured control point data. This is primarily achieved by extracting control point statements from the raw data. Standard control point terminology is then obtained based on these statements, and the structured control point data is derived from this standard terminology. Specifically, the raw control point data can be imported quality plans from historical procurement processes, including documents in formats such as Word and PDF. These documents contain technical standards and specifications (RCC-M / ASME / GB), management procedures, and manufacturing process libraries used in actual manufacturing scenarios. Next, deep learning-based document layout analysis technology can be used to accurately identify tables, hierarchical headings, and process descriptions within the document, extracting control point statements related to control points, such as "equipment code," "process name," "process parameters," and "control point type." After obtaining the control point statements, terminology normalization can be performed to extract standard control point terminology. Furthermore, steps such as entity extraction, attribute value matching, ambiguity resolution, and format output can be performed on the standard control point terminology to transform it into machine-readable structured control point data. For example, synonym mapping and entity linking techniques can be used to uniformly map different expressions such as "tensile test," "tensile strength test," and "tensiletest" to standard control point terminology, eliminating semantic ambiguity and realizing the transformation from standard control point terminology to structured control point data. Therefore, the final structured control point data includes machine-readable equipment codes, process names, process parameters, control point types, and standard clauses. Subsequently, a five-dimensional knowledge graph can be constructed based on the structured control point data, namely, a knowledge graph of equipment-component-process-standard clause-control point, thereby providing relevant information for subsequent control point recommendations.

[0021] In some specific embodiments, refer to Figure 2 Step S2 may further include steps S21-S23. Specifically, step S21 may include feature vectorization of the structured control point data to obtain control point semantic vectors; specifically, based on the content of the five-dimensional association knowledge graph obtained from the structured control point data, the description of the process to be controlled and the text in the control point standard database may be converted into control point semantic vectors respectively. The control point semantic vectors transform natural language semantic information into numerical expressions in a high-dimensional space, enabling the identification of semantically matched standard clauses without strict textual consistency, thus achieving intelligent matching of standard clauses under non-precise text conditions. Further, step S22 may be performed after obtaining the control point semantic vectors.

[0022] Furthermore, step S22 may include calculating the similarity of the structured data of control points based on the semantic vectors of the control points. The similarity can be calculated using the following formula: S = w1 S_{edit}+w2 S_{seq}+w3 S_{jaccard}+w4 S_{semantic}. Where S is the similarity, S_{edit} is the edit distance similarity, S_{seq} is the sequence matching similarity, S_{jaccard} is the set overlap similarity, S_{semantic} is the deep semantic similarity, w1 is the weight corresponding to edit distance similarity, w2 is the weight corresponding to sequence matching similarity, w3 is the weight corresponding to set overlap similarity, and w4 is the weight corresponding to deep semantic similarity. That is, in some specific embodiments, the four-dimensional similarity calculation includes edit distance similarity calculation, sequence matching similarity calculation, set overlap similarity (Jaccard similarity) calculation, and deep semantic similarity calculation (based on a Pre-trained Language Model, such as BERT / RoBERTa, RoFormer, SimCSE, Sentence-BERT (SBERT), or graph embedding similarity calculation using Graph Neural Networks (GNN)). Different weight coefficients can be matched to the four similarity calculations according to the actual situation, and the sum of the products of each weight and the corresponding similarity is the final similarity.

[0023] In some embodiments, step S23 may include confirming control point standardization information based on similarity. Specifically, the control point standardization information can be determined by judging the relationship between similarity and a first threshold, and the first threshold can also be dynamically adjusted according to the equipment level (nuclear safety level / non-nuclear level). If the similarity score exceeds the first threshold, the control point standardization information in the standard database (including multiple ASME and GB standards and management procedures for manufacturing processes) is automatically locked, and the mandatory descriptions (such as "must", "should", "should") regarding control point settings in the control point standardization information are extracted. For example, the national standard GB / T 228.2-2015 for high-temperature tensile testing methods stipulates that during the test, the temperature within the gauge length of the specimen should be maintained within the specified temperature allowable deviation range; after reaching the set temperature, it should be kept at that temperature for a sufficient time to ensure uniform specimen temperature before applying a tensile load. In this case, the clause includes the mandatory description "should", and this mandatory description is extracted. Furthermore, for example, in some practical application scenarios, the first threshold can be set to 0.9. If the calculation finds that the similarity between a certain process and the RCC-MM2123 clause after four-dimensional similarity calculation is as high as 0.92, then the content of the clause is parsed, and the "shall be witnessed" related content in the standardization information of the control point is identified. Then the standard control point type corresponding to the process is point W.

[0024] In some specific embodiments, in step S3, the control point settings of similar processes in the historical database can be aggregated and statistically analyzed according to dimensions such as equipment category (pump, valve, container, etc.), material type, and manufacturing process (casting, forging, welding, etc.) to obtain historical control point information. Further, the weights of the biased control points and the abnormal control points can be determined based on historical biased control points and historical abnormal control points, thus identifying abnormal settings in the historical control point information. For example, if a process is set as point W in 90% of projects, but as point N / A in some projects, then point W is a historical biased control point, and point N / A is a historical abnormal control point. Combining this with the project's quality feedback records (such as non-conformity records (NCR), experience feedback, etc.), the abnormal data is weighted down. Finally, the historical control point type can be determined based on the weights of the biased control points and the abnormal control points. For example, in the above example, point W has a weight of 90%, while point N / A has a weight of 10%. Since point W has a higher weight, it can be used as the historical control point type. In some embodiments, a recommended intensity heatmap can be generated based on process-control points, which can intuitively display the historical frequency distribution and confidence interval of each option H / W / R / N / A, and help to better select the type of historical control point.

[0025] In some embodiments, step S4 is to confirm the control point selection decision based on the standard control point type and the historical control point type. In some specific embodiments, a Bayesian inference model can be introduced to calculate the posterior probability of the control point type corresponding to the standard control point type and the historical control point type under a given device attribute, and the maximum probability can be selected as the recommendation result. Further, it can be referred to... Figure 3 The process can include step S31, determining whether the standard control point type has a mandatory description; step S32, if the determination is no, identifying abnormal point selection risk cases based on historical abnormal point selections, and generating an abnormal point selection traceability card based on the abnormal point selection risk cases; step S33, if the standard control point type is the same as the historical control point type, generating a point selection recommendation traceability card based on the standard control point type and the historical control point type; and step S34, determining the control point selection decision based on the abnormal point selection traceability card and the point selection recommendation traceability card. The control point selection decision mainly includes the original text and number of the cited standard clauses, the number of historical similar cases, the items and setting ratios, and the recommendation confidence score. In some embodiments, if the standard control point type has a mandatory description (e.g., regulations require it to be set as an H point), then even if the historical control point type is not an H point, the historical control point type can be ignored, and the mandatory requirements of the standard control point type can be directly used to select control points to ensure compliance. The traceability card can clearly show the regulatory source and historical data support for each recommendation, fully meeting the stringent requirements of the nuclear power industry for quality traceability, and greatly reducing the difficulty of quality review.

[0026] In some specific embodiments, the control point selection method 10 can also provide a visual interface for staff, push control point selection decisions, and allow staff to "adopt," "modify," or "reject" the recommended results of the control point selection decisions. For items that deviate from the control point selection decisions, staff are required to fill in the reasons for modification (such as "special process requirements"). In some embodiments, the final data after manual correction can be used as a high-quality labeled sample, updated in real time to the historical database of selected points, and trigger incremental training of the model, automatically adjusting the similarity algorithm weights and statistical cardinality to further improve the reliability of supervision.

[0027] The control point selection method 10 will now be described in conjunction with a specific implementation method. In the procurement quality plan for the main pump casing (equipment code: PUMP-001) of a nuclear power project, a key process is included: "SA-508Gr.3Cl.1 forging high-temperature tensile test". First, control point selection method 10 can automatically read the manufacturing process flow table of the equipment. Then, it identifies the process description "high-temperature tensile test". First, it needs to normalize "high-temperature tensile test" and map it to the standard control point term "HighTemperatureTensileTest". Then, it extracts the associated attributes: material grade "SA-508Gr.3Cl.1", equipment type "main pump casing", and safety level "nuclear level 1", and converts it into machine-readable structured control point data. Furthermore, searches can be conducted in the RCC-MM2000 and ASME Section III standard libraries, and the similarity of the process can be calculated using four-dimensional similarity. For example, if the similarity between this process and clause RCC-MM2123 is as high as 0.92, then the content of that clause can be analyzed to identify the selected point matching information "shall be witnessed," thus determining it as a mandatory W-point requirement. Next, the manufacturing data of the main pump casings for all nuclear power projects of the company over the past 10 years can be retrieved from the historical database. Statistical analysis of the historical database reveals that in 15 similar quality plans, this process was set as a W-point 13 times and as non-witnessed 2 times (N / A). At this point, further analysis of projects not involved in witnessing can be conducted. For example, if a subsequent experience feedback event record shows a quality problem, this abnormal case is automatically marked and its weight is reduced in the statistical analysis. Finally, a control point recommendation traceability card is generated, pointing to point W (weighted percentage 92.85%), and an abnormal control point traceability card is generated, pointing to the N / A point case. At this time, the control point selection decision is to select point W, but at the same time, a quality risk warning will be issued.
