[0002] Assembly Outline, or AO for short, is an important carrier of assembly execution work in the aircraft manufacturing process. The carrier of assembly execution work has changed from cards to AO, and it has also experienced a change from paper documents to paperless. However, for a long time, the compilation of AO documents has still been done manually, and the development of technology has not brought about innovation in the compilation method.

[0003] The manual compilation of AO has problems such as low efficiency, strong dependence on manual experience, low knowledge reuse rate, and poor knowledge inheritance. Process personnel are often tired of compiling AO documents, but neglect to analyze and optimize the assembly process. The compilation process of AO documents is characterized by cumbersome process, wide range of knowledge involved, and relatively fixed compilation content. It requires process personnel to have extensive knowledge of process details. This knowledge is often stored in the form of documents, tables, etc., lacking structured, explicit and intuitive expression. At the same time, AO document compilation requires process personnel to have in-depth theoretical knowledge of the process. This knowledge is often in the experience of process personnel and often needs to be obtained through communication between process personnel. There are potential problems such as low efficiency of knowledge transfer and incomplete information transfer. The loss of process knowledge may be caused by the loss of a certain process personnel.

[0021] Embodiment 1: This embodiment proposes an AO document compilation method based on a typical parameter library, which specifically includes the following steps: Step S1: calling the semantic parsing method to parse the process knowledge file and obtain structured description content.

[0022] The semantic analysis method includes lexical analysis, grammatical analysis and syntax analysis.

[0024] Step S2: Acquire structured process knowledge based on the structured description content, and construct a process knowledge parameter library through logical analysis.

[0025] The step S2 specifically includes the following steps: Step S21: acquiring structured process knowledge content from the structured description content, and classifying and analyzing it to obtain structured process knowledge content after classification and analysis; The step S21 specifically includes the following steps: Step S211: calling a clustering classification algorithm to preliminarily classify and obtain structured process knowledge content from the structured description content; Step S212: using the data structure of the AO document as input, reanalyzing the process knowledge content after preliminary classification; Step S213: Perform classification analysis according to the classification structure to obtain structured process knowledge content after classification analysis.

[0026] Step S22: acquiring the process knowledge content that has been stored in a structured manner, adding field content according to the characteristics of the aircraft and cleaning it, so as to obtain the cleaned process knowledge content that has been stored in a structured manner; Step S23: construct a process knowledge parameter library based on the structured process knowledge content after classification and analysis and the cleaned and structured stored process knowledge content to form a process parameter library logic map.

[0027] Step S3: Analyze the logical association between the process knowledge parameter library and the AO document structure, and construct an AO document compilation parameter search logic diagram.

[0028] The step S3 specifically includes the following steps: Step S31: Analyze the structured field content of the AO document and split it into corresponding categories; Step S32: According to the split categories, analyze the relationship with the corresponding parameter library, construct the relationship between the AO document structure field and the parameter library, and store it in the form of triples; Step S33: Based on the triple content, a relationship logic diagram between the AO document fields and the parameter library fields is formed, and an AO document compilation parameter search logic diagram is constructed.

[0029] Step S4: Search the logic diagram according to the AO document compilation parameters, process the AO structured fields, and generate the AO document content.

[0030] The step S4 specifically comprises the following steps: Step S41: Process according to the set processing logic and construct the logical processing relationship of the triple; the processing logic is L{L1, L2, L3...Li}, recorded as<Ai,Di,Ci,Li> , where Li represents the processing logic; Step S42: Process the AO document root nodes one by one, assemble the processed contents according to the AO document format, and generate AO document contents that meet the requirements.

[0031] Working principle: This embodiment first calls the semantic parsing method to obtain structured description content; secondly, it obtains structured process knowledge, and logically analyzes and constructs a process knowledge parameter library; then it analyzes the logical association between the process knowledge parameter library and the AO document structure, and constructs an AO document compilation parameter search logic diagram; finally, it processes the AO structured fields and generates AO document content; through the structured processing of process knowledge, a graph network for AO document compilation is formed, and with the reasoning algorithm of the knowledge graph, an AO document compilation method based on a typical parameter library is implemented.

[0032] Embodiment 2: This embodiment is based on the above embodiment 1. Figure 1 , Figure 2 As shown, a specific embodiment is used for description.

[0033] Step S1: Use semantic analysis methods such as vocabulary analysis, grammatical analysis, and syntax analysis to process existing process knowledge documents or tables to obtain structured description content.

[0034] In order to better expand the width and breadth of process knowledge, it is necessary to perform semantic analysis on a large number of process files and process summary documents currently stored in the form of text or tables. Semantic analysis uses existing mature algorithms, including rule-based algorithms and machine learning-based algorithms. The objects of analysis include text, tables, graphs, 3D models, etc. The main analysis includes common nouns, special nouns, parameter values, special requirements, bills of materials, etc.

[0035] Through this step, the standard parts list, aircraft material list (including drawing number, name, cabin space and other information), hole making information, tooling information, etc. are obtained.

[0036] Step S2: Perform logical analysis on the structured process knowledge, build a process knowledge parameter library, and form a process parameter library logic map.

[0037] The construction of process knowledge parameter library is mainly divided into two parts: (1) The structured process knowledge content obtained in step S1; (2) Process knowledge content that has been stored in a structured manner.

[0038] For the second part of the process knowledge that has been stored in a structure, the original parameter library structure is used. According to the characteristics of the aircraft, the required field content is added. For this part of the process knowledge, the focus is on cleaning the data and removing the wrong data, old data, and dirty data.

[0039] Regarding the process knowledge of the structure obtained in step 1 of the first part, since it only contains vocabulary, parameters and other contents, it has not been classified and analyzed. Therefore, the following steps need to be used to process this part: 1) With the help of existing clustering and classification algorithms, such as K-Means, DBSCAN, GMM, swarm intelligence clustering algorithm and other algorithms, the analyzed process knowledge is preliminarily classified.

[0040] 2) Using the data structure of the AO document as input, the process knowledge is analyzed again.

[0041] 3) Based on the classification structure, construct a parameter library. The fields of the parameter library are based on the extracted structured parameter content.

[0042] According to the classification, it is mainly divided into two parts: process content and process supporting content. It can be further divided into: hole making information, installation information, material information, tooling information and other contents.

[0043] Step S3: Analyze the logical relationship between the process knowledge parameter library and the AO document structure, and construct an AO document compilation parameter search logic diagram.

[0044] Analyze the contents of the structured fields of the AO document and split them into corresponding categories. For each category, analyze the relationship with the corresponding parameter library, build the relationship between the AO document structure field and the parameter library, and store it in the form of triples.<Ai,Di,Ci> , where Ai represents the AO document field, Di represents the parameter library name, and Ci represents the parameter library field.

[0045] Based on the triple content, a logical diagram of the relationship between the AO document fields and the parameter library fields is formed.

[0046] The main contents are as follows <Material column, bill of materials, drawing number>, <Tool bar, tool parameter library, tool drawing number>... Step S4: Generate AO document content.

[0047] The process of generating AO documents is the process of processing AO structured fields. Processing is performed according to a certain processing logic, which is defined as L{L1, L2, L3...Li}, and the logical processing relationship of the triples is constructed and recorded as<Ai,Di,Ci,Li> , where Li represents the processing logic.

[0048] According to the AO document root nodes, they are processed one by one, and the processed contents are assembled according to the AO document format, and finally the AO document content that meets the requirements is generated.

[0049] The main processing logic consists of replacement, combination and other relationships. Replacement means replacing variable parameters, and combination means concatenating multiple fields into one field content.

[0050] Working principle: This embodiment extracts, analyzes and stores existing process knowledge in a structured manner, and uses clustering and other methods to perform logical analysis on it to complete the construction of the graph for AO document content compilation. Based on the graph, the retrieval and generation of AO document content are completed; through the structured processing of process knowledge, a graph network for AO document compilation is formed, and the reasoning algorithm of the knowledge graph is used to implement the AO document compilation method based on the typical parameter library.
