[0002] Nuclear power plant maintenance work orders are formal documents used in the maintenance and repair of nuclear power plant equipment to record and manage all aspects of maintenance activities. Preparing nuclear power plant maintenance work orders involves a large workload and carries a high risk of human error. According to statistics from a certain nuclear power company, the average annual number of preventative work orders is over 30,000, and corrective work orders exceeds 20,000. For example, in 2023, the total number of work orders was 59,381.

[0003] Nuclear power plant maintenance work orders include preventative work orders and corrective work orders. Preventative work order preparation is extensive, characterized by recurring execution on a monthly, quarterly, annual, and fuel cycle basis. Preventative work order preparation requires compiling and gathering drawings from multiple systems, involving procedures, flowcharts, wiring diagrams, and verification sheets, much of which can be referenced from previous work orders. Preventative work orders have a standardized package format, consistent preparation processes, clear steps, and high similarity across different disciplines. Corrective work order preparation, on the other hand, is time-consuming, requiring the preparation of various resources such as procedures, drawings, risks, experience feedback, electronic seals, licenses, and components.

Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] This invention provides an automatic preparation method for maintenance work orders in nuclear power plants. Based on artificial intelligence big data modeling technology, it realizes the automatic creation of maintenance work orders, replacing the manual preparation process. This significantly reduces human error, greatly improves the efficiency of maintenance work order preparation, significantly shortens the unit downtime / maintenance window, and achieves full-flow automation. It also significantly reduces labor and management costs, and can automatically accumulate work order templates, fault modes, maintenance steps, man-hour consumption, and spare parts consumption data to form a knowledge base for the power plant.

[0019] refer to Figure 1 The automatic preparation method for maintenance work orders at this nuclear power plant includes the following steps: Step S10: Receive maintenance work order preparation instructions.

[0020] In practical application, the maintenance preparation engineer opens a webpage on computer terminal 604. After entering the preparation interface, computer terminal 604 retrieves the work order list and details from ERP server 603 and displays them on the preparation interface of computer terminal 604. The maintenance preparation engineer filters the work orders that need to be prepared according to work requirements, i.e., the work orders to be prepared, and clicks the "Start Preparation" control. Computer terminal 604 then receives the work order preparation trigger instruction and generates a maintenance work order preparation instruction based on the trigger instruction, which is sent to system server 601. System server 601 receives the maintenance work order preparation instruction. This maintenance work order preparation instruction includes the maintenance work order code.

[0021] Step S20: Obtain the work orders to be prepared according to the maintenance work order preparation instruction, and identify the type of the work orders to be prepared. The types of work orders to be prepared include: preventive work orders and corrective work orders.

[0022] Specifically, after receiving the maintenance work order preparation instruction, the system server 601 can directly obtain the maintenance work order code of the work order to be prepared and identify its work order type. Preventive work orders are automatically prepared according to step S30, and corrective work orders are automatically prepared according to step S40.

[0023] Step S30: If the work order to be prepared is a preventive work order, the preparation items of the work order to be prepared will be automatically completed based on the structured standard package and the previous work order corresponding to the work order to be prepared.

[0024] In some embodiments, step S30, automatically preparing the preparation items of the work order to be prepared based on the structured standard package and the previous work order corresponding to the work order to be prepared, includes: obtaining the standard package information of the structured standard package and the work order information of the previous work order; generating the work order information of the work order to be prepared based on the standard package information and the work order information of the previous work order; and automatically writing the content of each preparation item based on the work order information of the work order to be prepared, thereby completing the preparation of the work order to be prepared.

[0025] Optionally, such as Figure 2 and Figure 3 As shown, the standard package information includes: process information, component information, risk and safety measures (risk analysis and safety measures) information, process-level risk information, electronic seal information, and experience feedback information. The previous work order information includes: process enhancement information, header data, RWP information, hot work permit information, special work permit information, fire protection system isolation information, document information, coordination ticket notification information, coordination ticket work order information, and coordination ticket WCA.

[0026] The preparation items required for preventive work orders include: process, component, risk and safety measures, process-level risk, electronic seal, experience feedback, process enhancement, header data, RWP, Z11 hot work permit, Z14 special operation permit, Z33 fire protection system isolation unit, document, coordination ticket notification, coordination ticket work order, and coordination ticket WCA, totaling 16 preparation items.

[0027] In some embodiments, the content of each preparation item is automatically generated based on the work order information of the work order to be prepared, as follows: (1) Automatically refresh the process information of the work order to be prepared based on the process information.

[0028] Specifically, the system automatically retrieves the standard packages attached to the work order to be prepared and automatically refreshes the process information of the work order based on the content of the standard packages. The refreshed process information includes: process, sub-process, work center, process confirmation status, factory, control code, label text, system conditions, long text, process execution identifier, function location, and measurement point. By refreshing the process information of the work order to be prepared, the system ensures that the process information of the work order is identical to that of the standard packages. It should be noted that if the work order to be prepared does not have a standard package attached, the system will remind the preparation engineer to attach it. That is, if it detects that a work order to be prepared does not have a standard package attached, it will output a reminder to attach it.

[0029] (2) Automatically refresh the component information of the work order to be prepared based on the component information.

The refreshed process-level risk information includes: process high-risk information, namely process, sub-process, process description, label text, label text description, activity category, and activity category description.

[0035] (5) Automatically refresh the electronic seal information of the work order to be prepared based on the electronic seal information.

[0036] Specifically, the system automatically retrieves the electronic seal information of the standard package and refreshes the electronic seal information of the work order to be prepared based on the electronic seal information of the standard package to ensure that it is identical to the content of the standard package. The refreshed electronic seal information includes: serial number, electronic seal code, electronic seal name, electronic seal risk, and countermeasures.

[0037] (6) Automatically refresh the experience feedback information of the work orders to be prepared based on experience feedback information.

[0038] Specifically, the system automatically retrieves the experience feedback information from the standard package and refreshes the experience feedback information of the work order to be prepared based on the experience feedback information from the standard package to ensure that it is identical to the content of the standard package. The refreshed experience feedback information includes: event code (previous work order), event name (automatically populated), failure code (previous work order), failure point (automatically populated), and feedback measures (previous work order).

[0039] (7) Automatically refresh the process enhancement information of the work order to be prepared based on the process enhancement information.

[0040] Specifically, the system automatically retrieves the previous work order corresponding to the work order to be prepared. The previous work order number is taken from the "Previous Order" number in the "Work Order-Plan" section. This allows the system to obtain the process enhancement information of the previous work order and refresh the process enhancement information of the work order to be prepared based on this information. The refreshed process enhancement information includes: a list of cooperating processes and a list of cooperating tickets. The list of cooperating processes includes: a cooperating notification, a cooperating work order, a process, a sub-process, a single-ticket interlock, a short text of the process, a label text, a label text description, system status, and work center. The list of cooperating tickets includes: a cooperating notification, a notification description, system status, user status, a cooperating work order, a work order description, work supervisor, and contact information.

[0041] It should be noted that the coordination ticket attached to the work order process must be executed after the coordination ticket is created.

[0042] (8) Automatically refresh the header data of the work orders to be prepared based on the header data.

[0043] Specifically, the system automatically retrieves the header data of the previous work order corresponding to the work order to be prepared, and refreshes the header data of the work order to be prepared. The refreshed header data includes: Planner (Preparation Engineer), and the Planner (Preparation Engineer) field is taken from the current work order operator.

[0044] (9) Automatically create RWPs for work orders to be prepared based on RWP information.

[0045] Specifically, the system automatically retrieves the previous work order corresponding to the work order to be prepared. The previous work order number is taken from the "Previous Order" number in the "Work Order - Plan" section, thereby obtaining the RWP information of the previous work order. Based on the RWP information of the previous work order, the system automatically creates the RWP for the work order to be prepared. The created RWP includes: work order information, responsible person, location information, dose prediction, historical operation information, and overall risk analysis. Work order information includes: work order type (obtained via interface), work order number (obtained via interface), and work order description (obtained via interface). Responsible persons include: planning personnel group (obtained via interface), planning plant (obtained via interface), notification form (obtained via interface), maintenance center (obtained via interface), plant (obtained via interface), PM operation type (obtained via interface), preparation engineer (obtained via interface), system conditions (obtained via interface), and version (obtained via interface).

Overall risk analysis includes: sequence number, risk code (previous work order), risk description (obtained via API), safety measure code (obtained via API), and safety measure description (obtained via API).

[0046] RWP (Radiation Work Permit) is a licensing system used in nuclear power plants to regulate and manage all radiation-related work. It is divided into two categories: general RWPs and work order-based RWPs, applicable to different radiation work scenarios. General RWPs are created by radiation protection engineers and are applicable to work within the RCA (Radiation Control Area) where work orders are not used. Work order-based RWPs, on the other hand, correspond one-to-one with a work order, and their validity in the RCA begins from the completion of RWP approval until the work order is placed in the CSR (Completed Status). Work order-based RWPs are classified into four levels (0, 1, 2, and 3) based on radiation risk and are applicable to all work involving radiation-related maintenance work orders.

[0047] The main functions of RWP include: Radiation Risk Classification: Classifying radiation risks based on factors such as the maximum dose rate at the work site, collective dose prediction, and maximum individual dose prediction to ensure that radiation risks are controllable; Dose Prediction: Predicting doses during the work preparation phase and developing corresponding protective measures; Data Tracking and Analysis: Tracking and analyzing dose data in real time through the system to identify potential anomalies and correct them in a timely manner; Process Management: Managing the entire process from creation, approval, execution to closure to ensure the safe implementation of radiation work.

[0048] The RWP system consists of two main functional modules: the RWPMS system, which provides workflows for the creation, approval, tracking, and closure of RWPs; and the RMS system, which is used for the maintenance of radiation measurement data and the query of room radiation risks.

[0049] (10) Automatically create hot work permits for work orders to be prepared based on hot work permit information.

[0050] Specifically, the system automatically retrieves the previous work order corresponding to the work order to be prepared. The previous work order number is taken from the "Previous Order" number in the "Work Order-Plan" section, thereby obtaining the hot work permit information of the previous work order. Based on the hot work permit information of the previous work order, the system automatically creates a hot work permit for the work order to be prepared, namely a Z11 hot work permit (where Z11 is the code number in the system). The created Z11 hot work permit includes: basic information, hot work permit related information, hot work method, etc. The basic information includes: permit type (hot work permit), permit number (automatically generated after submission), subject (automatically generated after submission), process priority (previous work order), creator (current work order operator), creation time (automatically generated after submission), planned factory (current work order), applicant (current work order operator), and current node (applicant initiated hot work permit).

[0051] (11) Automatically create special work permits for work orders to be prepared based on special work permit information.

[0052] Specifically, the system automatically retrieves the previous work order corresponding to the work order to be prepared. The previous work order number is taken from the "Previous Order" number in the "Work Order-Plan" section. This allows the system to obtain the special work permit information from the previous work order and automatically create a special work permit for the work order to be prepared based on this information. This special work permit is designated Z14 (Z14 is the system code number). The created Z14 special work permit (PX ticket) includes: Basic Information 1, Basic Information 2, Reason for Special Work, Specific Work Method, Major High-Risk Processes and Corresponding Industrial Safety Risks, and Safety Measures. Basic Information 1 includes: Permit Type (Special Work Permit (PX Ticket)), Permit Number (automatically generated after submission), Subject (automatically generated after submission), Process Priority (Previous Work Order), Creator (Current Work Order Operator), Creation Time (automatically generated after submission), Planning Factory (Current Work Order), Applicant (Current Work Order Operator), and Current Node (Initiated by the Applicant).

Specific work methods (previous work order) include: online leak repair, ice blockage work, diving, live insulation removal, scaffolding erection in areas with operating 24kV and above transformers, hazardous chemical equipment work, scaffolding erection in areas with a risk of sudden steam ejection or steam leakage, equipment that is energized or surrounded by energized objects and does not meet the voltage level safety distance requirements, resin replacement, work involving non-isolated ambient temperature and pressure media, single-layer isolation work inside containers, diving in areas outside the power plant's safety net, standard special operations during major overhauls, removal of insulation at high-temperature leak points in stable and safe conditions, and work sources that require frequent access to the work area. Safety measures include: description (previous work order), main control telephone (previous work order), isolation office telephone (previous work order), and main control emergency telephone (previous work order).

[0053] (12) Automatically create fire system isolation orders based on fire system isolation information to prepare work orders.

[0054] Specifically, the system automatically retrieves the previous work order corresponding to the work order to be prepared. The previous work order number is taken from the "Previous Order" number in the "Work Order-Plan" section, thereby obtaining the fire system isolation information of the previous work order. Based on the fire system isolation information of the previous work order, the system automatically creates a fire system isolation form (i.e., a Z33 fire system isolation form, where Z33 is the system code number) for the work order to be prepared. The created Z33 fire system isolation form includes: Basic Information 1 and Basic Information 2. Basic Information 1 includes: License Type (Fire System Isolation Form), License Number (automatically generated after submission), Subject (automatically generated after submission), Process Priority (Previous Work Order), Creator (Current Work Order Operator), Creation Time (automatically generated after submission), Planned Factory (Current Work Order), Applicant (Current Work Order Operator), and Current Node (Initiated by the Work Supervisor).

[0055] (13) Automatically refresh the document information of the work orders to be prepared based on the document information.

[0056] Specifically, the system automatically retrieves the previous work order corresponding to the work order to be prepared. The previous work order number is taken from the "Previous Order" number in the "Work Order-Plan" section, thereby obtaining the document information of the previous work order, and refreshing the document information based on the document information of the previous work order. The refreshed document information includes: a work order process and document list, an execution file list, and execution files attached to the work order. The work order process and document list includes: sequence number, process, process description, item, type, document type, original file, program and file, document description, and quantity. The execution file list includes: sequence number, copy program number, type, document type, program and file, description, version, original file, whether it is structured, and whether it is the latest version. The execution files attached to the work order include: sequence number, process, process description, copy program code, item, whether it is structured, total number of attached programs, total number of program processes, type, document type, program and file, description, document description, and original file. It should be noted that the work order process and document list, as well as the work order attached execution file, are refreshed through the standard package. The execution file list needs to be regenerated based on the previous work order's generation status using the work order process and document list. The work order attached execution file needs to be correspondingly attached according to the previous work order's attached procedures. During actual execution, the "original files" in the standard package are automatically refreshed to the work order's "work order procedure and document list"; based on the original files, the system automatically creates an "execution file list" (structured standard package); if the previous work order uploaded a "local PDF supplementary list," then a "PDF file" identical to the previous work order is created; the work order attached execution file needs to refresh the standard package - document - process instruction list.

[0057] (14) Automatically create a coordination ticket notification form for a work order to be prepared based on the coordination ticket notification form information.

[0058] Specifically, the system automatically retrieves the previous work order corresponding to the work order to be prepared. The previous work order number is taken from the "Previous Order" number in the "Work Order - Plan" section, thereby obtaining the coordination ticket notification information of the previous work order. Based on the coordination ticket notification information of the previous work order, the system automatically creates the coordination ticket notification for the work order to be prepared. In actual execution: First, it determines whether the previous work order has a coordination ticket notification attached. If so, it creates the corresponding coordination ticket notification. If the coordination ticket involves a work order, a coordination ticket work order is also created simultaneously. If there is no work order, there is no need to create a coordination ticket work order; only the coordination ticket notification is created. Second, the "Request Conditions" field of the coordination ticket notification is filled in according to the "Header Data - System Conditions" field of the main work order. If the main work order's system condition field is O or T, the "Main Work Order Version Number" of its coordination ticket notification is taken as the work order version number; if it is not an O or T field, the main work order version number is automatically filled with N, and the version number of its coordination ticket notification field is also automatically filled with N. After creating a coordination ticket notification, the new master work order number must be synchronously updated in the coordination ticket notification. The "Coordination Days" field must be consistent with the previous work order. Synchronously update the coordination ticket numbers involved in the [Work Order - Process - Process Short Text + Long Text] and the newly created coordination ticket work order number, automatically updating the ticket numbers. Then, in the newly created coordination ticket notification, the "Reporter" field in the [Notification Title] field needs to be modified. The reporter should be automatically entered as MI-Name-Phone Number (MI is the specialty corresponding to the preparing engineer; the phone number is obtained from the TYS Phone Directory system - 4G / 5G private network number; if this field is empty, use the office mobile phone number; the name is taken from the preparing engineer of the previous work order). If no data is available, it should be consistent with the previous work order. Simultaneously, the <Other Notification Data - Additional Notification Information> module of the newly created coordination ticket notification should be consistent with the coordination ticket notification information of the previous work order. For newly created coordination ticket notification forms, the "Subject" of <Other Data - Notification Title> is taken from the latest paragraph under the employee number of the preparation engineer of the previous coordination ticket notification form. The logic for finding the preparation engineer is as follows: based on the "Planner" field in the previous work order, identify the first paragraph of the preparation engineer's work order (the earliest paragraph edited by the preparation engineer).

[0059] (15) Automatically create a work order for a work order to be prepared based on the work order information of the work order.

[0060] Specifically, the system automatically retrieves the previous work order corresponding to the work order to be prepared. The previous work order number is taken from the "Previous Order" number in the "Work Order-Plan" section, thereby obtaining the coordination ticket information of the previous work order. Based on the coordination ticket information of the previous work order, the system automatically creates the coordination ticket work order for the work order to be prepared. The coordination ticket information includes: the previous coordination ticket notification (i.e., the coordination ticket notification corresponding to the previous work order), the previous coordination ticket work order (i.e., the work order corresponding to the previous coordination ticket notification), and the current work order operator (i.e., the person currently logged into the system for intelligent preparation (executor)). During execution, if the previous work order involves a coordination ticket, and a work order has been created for that coordination ticket, the newly created coordination ticket also needs to create a work order. The data of the new work order refers to the previous coordination ticket work order, and the data refresh follows the main work order data refresh logic (the main work order data mainly comes from the standard package, and the coordination ticket work order data mainly comes from the previous coordination ticket work order).

[0061] (16) Automatically create a coordination ticket WCA for a work order to be prepared based on the coordination ticket WCA information.

[0062] Specifically, the system automatically retrieves the previous work order corresponding to the work order to be prepared. The previous work order number is taken from the "Previous Order" number in the "Work Order-Plan" section, thereby obtaining the WCA information of the previous work order's coordination ticket. Based on the previous work order's WCA information, the system automatically creates the coordination ticket WCA for the work order to be prepared. The coordination ticket WCA information includes: the previous coordination ticket notification (i.e., the coordination ticket notification corresponding to the previous work order), the previous coordination ticket work order (i.e., the work order corresponding to the previous coordination ticket notification), and the current work order operator (i.e., the person currently logged into the system for intelligent preparation (executor)). During execution, the coordination ticket notification automatically creates and associates the corresponding isolation application form according to rules, based on whether the previous work order's coordination ticket notification has a WCA. The newly created isolation application form number replaces the short text + long text isolation application form number of the work order's process. When a coordinating work order from the previous work order exists in a WCA: If the previous work order and its coordinating work order are linked to the same WCA, then when creating the coordinating work order, the same WCA as the main work order should be linked simultaneously. After linking, the corresponding master-sub-ticket relationship needs to be set and displayed in the WCA. If the previous work order and its coordinating work order are not linked to the same WCA, then an independent coordinating work order WCA should be created simultaneously when creating the coordinating work order. If the coordinating work order from the previous work order does not exist in a WCA, there is no need to consider linking the WCA. Master-sub-ticket determination logic: If it is the main work order number, then the data is judged as a main ticket; if it is the coordinating work order number, then the data is a sub-ticket.

[0063] Step S40: If the work order to be prepared is a corrective work order, then based on the big model technology, the same or similar historical work orders will be automatically matched, and the preparation items of the work order to be prepared will be automatically completed based on the same or similar historical work orders.

[0064] In some embodiments, such as Figure 4 and Figure 5 As shown, in step S40, automatically matching historical identical or similar work orders (similar work orders are those with high similarity) based on large model technology includes: identifying historical identical or similar work orders through vectorized work order processing based on large model technology. Specifically, in step S40, automatically preparing the preparation items for the work order to be prepared based on historical identical or similar work orders includes: obtaining historical work order information; automatically writing the content of each preparation item for the work order to be prepared based on the historical work order information, thus completing the preparation of the work order to be prepared. Historical work order information includes: process information, component information, risk and safety measures information, process-level risk information, electronic seal information, header data, RWP information, hot work permit information, special operation permit information, fire protection system isolation information, experience feedback information, document information, coordination ticket notification information, coordination ticket work order information, coordination processes, and coordination ticket WCA.

[0065] The specific preparation items required for corrective work orders include: process, component, risk and safety measures, process-level risk, electronic seal, experience feedback, cooperating process, header data, RWP, Z11 hot work permit, Z14 special operation permit, Z33 fire protection system isolation unit, document, coordination ticket notification, coordination ticket work order, and coordination ticket WCA, totaling 16 preparation items. The difference is that preventative work orders are prepared by referring to standard packages and historical work orders, while corrective work orders are prepared by an AI model that automatically recommends historical work orders.

A target historical work order is selected from this list, and then the system automatically prepares a cooperation ticket notification for the work order to be prepared. The cooperation ticket notification must include: serial number, electronic seal code, electronic seal name, electronic seal risk, and countermeasures. Specifically, the system checks if a cooperation ticket notification is attached to the historical work order; if so, it creates the corresponding notification. If the cooperation ticket involves a work order, a cooperation ticket work order is also created simultaneously; if no work order exists, only the cooperation ticket notification is created. The "Request Conditions" field of the cooperation ticket notification is filled in based on the "Header Data - System Conditions" field of the main work order. If the master work order system condition field is O or T, the "Master Work Order Version Number" of its coordination ticket notification form will be the work order version number; if it is not an O or T field, the master work order version number will be automatically filled with N, and the version number of its coordination ticket notification form will also be automatically filled with N; after creating a coordination ticket notification form, the new master work order number must be updated synchronously to the coordination ticket notification form; the "Coordination Days" field must be consistent with the historical work orders; synchronously update the coordination ticket numbers involved in [Work Order-Process-Process Short Text + Long Text] and the newly created coordination ticket work order number, and automatically update the ticket number; for newly created coordination ticket notification forms, the "Reporter" field in the [Notification Form Header] field must be modified to indicate the currently logged-in user.

[0092] Reporter: Automatically enter MI-Name-Phone (MI is the major corresponding to the preparation engineer; Phone number is obtained from the TYS Phone Directory system - 4G / 5G private network number; if this field is empty, use the office mobile phone number; Name is taken from the preparation engineer in the historical work order); if no data is obtained, it is consistent with the historical work order; for newly created coordination ticket notification forms, the <Other Data - Additional Information> module of the notification form is consistent with the coordination ticket notification information of the historical work order; for newly created coordination ticket notification forms, the "Subject" of <Other Data - Notification Header> is taken from the latest paragraph under the employee number of the preparation engineer in the previous coordination ticket notification form. The logic for finding the preparation engineer is: according to the "Planner" field in the historical work order, identify the first paragraph of the preparation engineer's text. (The earliest paragraph edited by the preparation engineer).

[0093] (14) Automatically prepare corrective work orders to match the process.

[0094] The system retrieves a list of historical work orders based on the input query criteria and transmits this list to an AI model. The AI ​​model is trained to recognize and automatically recommend and display reference historical work order information. A target historical work order is selected from this list, and the system automatically prepares the necessary coordination procedures based on that target work order. The coordination procedures to be prepared include: a coordination procedure list (coordination notification, coordination work order, procedure, sub-procedure, one-ticket interlock, procedure short text, label text, label text description, system status, and work center) and a coordination ticket list (coordination notification, notification description, system status, user status, coordination work order, work order description, work supervisor, and contact information). During execution, the system automatically prepares the coordination procedure information based on the target historical work order component. The main interfaces involved are as follows: Order View: Interface ID: MI_IS_IMP1_REQUEST; Operation ID: ORDERREAD; Main function: Retrieves detailed work order information by work order number.

[0095] (15) Automatically prepare corrective work orders in conjunction with work tickets.

[0096] The system retrieves a list of historical work orders based on the input query criteria and transmits this list to an AI model. The AI ​​model is trained to identify and automatically recommend and display reference historical work order information. A target historical work order is selected from this list, and the system automatically prepares the necessary coordination ticket based on that target historical work order. Specifically, the system automatically prepares the coordination ticket information based on the target historical work order component. If a historical work order involves a coordination ticket, and a work order has been created for that ticket, a new work order with the same coordination ticket must also be created. The data for the new work order references the historical coordination ticket work order, and data refresh follows the main work order data refresh logic.

[0097] (16) Automatically create coordination tickets (WCA) for corrective work orders.

[0098] The system retrieves a list of historical work orders based on the input query conditions and transmits the list to the AI ​​model. The AI ​​model is trained to identify and automatically recommend and display reference historical work order information. The system selects the target historical work order from the reference historical work order list and then automatically prepares the coordination ticket (WCA) for the work order to be prepared based on the target historical work order. The specific implementation is as follows: The coordination ticket notification form automatically creates and associates a corresponding isolation application form according to the rules based on whether the coordination ticket notification form of the previous work order is linked to a WCA. The newly created isolation application form number replaces the short text + long text isolation application form number of the work order process. When the coordination ticket work order of the previous work order has a WCA: If the previous work order and its coordination ticket work order are linked to the same WCA, then when creating the coordination ticket work order, the same WCA as the main ticket work order is linked simultaneously. After linking, the corresponding master-sub-ticket relationship needs to be set and displayed in the WCA. If the previous work order and its coordination ticket work order are not linked to the same WCA, then an independent coordination ticket work order WCA is created simultaneously when creating the coordination ticket work order. If the coordination ticket work order of the previous work order does not have a WCA, there is no need to consider linking the WCA. The master-sub-ticket judgment logic: If it is the main work order number, then the data is judged as a master ticket; if it is the coordination ticket work order number, then the data is a sub-ticket.

[0099] Finally, after the automatic preparation of the maintenance work order is completed, the progress and results of the work order preparation are displayed on the 604 webpage on the computer terminal.
