Description

Technical Field

[0001] This application relates to the field of computer technology, and in particular to a method, apparatus, computer equipment, and storage medium for managing nuclear island installation plans. Background Technology

[0002] Nuclear island installation in a nuclear power plant is a complex systems engineering project, involving multiple disciplines such as mechanics, materials, electrical engineering, and instrumentation. It involves a wide variety of physical objects, a large amount of data, and complex work within each discipline, across disciplines, and across different trades. The engineering plan related to nuclear island installation is a four-level plan. Management personnel need to implement four-level plan management for nuclear island installation to continuously improve project management levels, enhance lean management capabilities, accelerate project progress, and reduce project costs. This necessitates the management of the entire nuclear island installation process plan.

[0003] The existing Level 4 nuclear island installation plan is developed based on empirical data and has no strong logical connection with the overall project goal—system handover. Management focuses primarily on work packages and quantities. Contractors manually generate Level 5 plans (based on drawings) and Level 6 plans (based on components) based on the Level 4 plan. However, this existing method suffers from coarse-grained planning management and fails to achieve lean management in plan execution. The Level 6 plan deviates from the parent plan and fails to reflect the requirements of the Level 4 parent plan's objectives, thus hindering precise and efficient plan management.

[0053] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0054] Nuclear power plant projects are typically divided into six levels, which include:

[0055] Level 1 Plan: Overall project schedule and milestones (top-level control by the owner / investor);

[0056] Secondary plan: Interface plans for each specialty (design / procurement / civil engineering / installation / commissioning);

[0057] Level 3 plan: Nuclear island installation contract-level plan, which specifies the start and completion milestones for major systems / areas;

[0058] Level 4 Plan: The core control plan for nuclear island installation, serving as the benchmark and objective for the construction unit's internal progress management;

[0059] Level 5 Plan: Monthly / Bi-monthly Rolling Plan (to guide construction teams in execution);

[0060] Level 6 plan: Weekly / daily work plan (to be directly executed by on-site work teams).

[0061] The contractor's weekly plans are entirely self-managed, and the engineering company cannot dictate the contractor's weekly work plan. Contractors may prioritize tasks with lower difficulty and higher performance, potentially leading to discrepancies between weekly plan objectives and the overall project goals. After a Level 4 plan is updated, it needs to be manually broken down into Level 5 and Level 6 plans, a process that takes 1-2 weeks, causing a disconnect between the on-site execution plan and the Level 4 plan. On-site execution deviations in the Level 6 plan (such as process delays or resource shortages) rely on manual reporting, and data transmission to Level 5 and Level 4 management takes 3-5 days, missing the optimal adjustment window. Adjustments to a Level 1 plan require cross-level manual communication and coordination of related plans, and issuing adjustment instructions to on-site teams is time-consuming, easily leading to the contradiction of "plan changes, execution remains unchanged." Minor deviations in Level 6 plan processes cannot be transmitted to higher-level plans in real time, making it difficult for management to predict the impact on Level 4 milestones, resulting in delayed risk warnings.

[0062] Based on the aforementioned deficiencies, the nuclear island installation plan management method provided in this application embodiment can be applied to, for example... Figure 1 In the application environment shown, terminal 101 communicates with server 102 via a network. A data storage system can store the data that server 102 needs to process. The data storage system can be integrated onto server 101 or located on a cloud or other network server. Terminal 101 can be, but is not limited to, various personal computers, laptops, smartphones, tablets, etc. Server 102 can be implemented using a standalone server or a server cluster consisting of multiple servers.

[0063] In one exemplary embodiment, such as Figure 2 As shown, a method for managing nuclear island installation plans is provided, which can be applied to... Figure 1 Taking server 101 as an example, the explanation includes the following steps:

[0064] S201, in response to a request for the development of a nuclear island installation plan for a nuclear power plant, obtains the nuclear island installation requirements, nuclear island installation specifications, and master plan for the nuclear power plant.

[0065] The nuclear island is the core functional area of ​​a nuclear power plant, serving as a crucial component for nuclear fission reactions, heat removal, and related nuclear safety functions. The nuclear island installation plan is a specialized engineering schedule and operational control plan developed for the entire installation process of the nuclear island, characterized by hierarchy, coordination, and constraints. In this embodiment, the nuclear island installation plan includes at least two levels of plans, with the master plan being the first-level plan among these two levels.

[0066] Nuclear island installation requirements are comprehensive implementation needs based on the overall engineering construction goals of the nuclear power plant, project schedule requirements, installed capacity, site conditions, owner control requirements, nuclear island equipment supply cycle, and construction resource allocation (manpower, machinery, tools, and site). Nuclear island installation requirements include, but are not limited to, overall project schedule milestones, key milestones, installation quality levels, safety control objectives, resource guarantee requirements, and interface coordination requirements. Nuclear island installation specifications are mandatory standards, specifications, technical procedures, and safety guidelines formulated by the state and the nuclear power industry for nuclear island installation.

[0067] A multi-level plan is a planning system of at least two levels for nuclear island installation, divided according to control granularity, implementing entity, and process detail. For example, a multi-level plan typically has a three-level standard architecture, which can be expanded to four levels depending on the scale of the project. The first level is the master control plan (project level / engineering level), the second level is the specialized sub-plan (professional level / system level), and the third level is the work execution plan (team level / process level). Control is implemented from top to bottom, and feedback is provided from bottom to top between levels.

[0068] The master plan is the top-level overall control plan at the first level in the multi-level nuclear island installation plan. It is a programmatic and framework plan, serving as the basis and core guideline for the development of all subsequent sub-level plans. In the embodiments of this application, the master plan is a fourth-level plan in the nuclear power engineering plan.

[0069] Optionally, after receiving a request to formulate a nuclear island installation plan for a nuclear power plant through the engineering management platform, the authorization verification of the request initiator is completed. Nuclear island installation requirement data is collected through a combination of platform integration, data import, and manual entry. First, it integrates with the nuclear power plant EPC (Engineering, Procurement, and Construction) management system to extract the total project duration, milestones, and resource allocation plan; second, it integrates with the equipment supply management system to obtain the factory delivery, transportation, and arrival times of core nuclear island equipment; and third, it manually enters information on construction site conditions, construction team configuration, equipment availability, and special control requirements from the owner to form a standardized requirement dataset.

[0070] A nuclear power plant installation specification database has been established, storing national nuclear safety standards, industry specifications, and other specifications. The engineering management platform automatically matches the corresponding specification clauses based on the nuclear island model and installation scope, extracts core specification content such as process flow, quality standards, safety requirements, and prohibitions, and forms the nuclear island installation specification.

[0071] The master plan is prepared and approved in advance by the top management department of nuclear power engineering and stored in the engineering plan database. The engineering management platform accurately retrieves the approved first-level master control plan based on the nuclear power plant project number and nuclear island number corresponding to the request. This plan includes core information such as the overall construction period, major milestones, professional division, and total workload.

[0072] The project management platform automatically verifies the three types of data it acquires, identifies issues such as conflicts between requirements and specifications, discrepancies between the parent plan nodes and equipment arrival times, and missing data, generates a data verification report, initiates requests to complete or correct abnormal data, and completes data standardization and formatting after verification.

[0073] S202, based on the nuclear island installation requirements and specifications, determines the linkage mapping rules between different levels of plans and the process constraint rules during the nuclear island installation process.

[0074] Among them, the linkage mapping rules between different levels of plans are used to define the technical rules for the association, data synchronization, and node linkage between plans at different levels and between different special plans at the same level. The process constraint rules are a collection of logical sequences, spatial constraints, resource constraints, quality constraints, safety constraints, and interface constraints between various processes during nuclear island installation. These are rigid rules that the nuclear island installation processes cannot be reversed. In the embodiments of this application, the process constraint rules include at least one of the following: the sequential execution order of various nuclear island installation processes, process connection relationships, component installation constraints, workspace constraints, resource allocation constraints, and installation compliance requirements.

[0075] Optionally, based on the professional division and engineering scope of the parent plan, the specific hierarchical division and control granularity of the multi-level plan are clarified, and a one-to-one correspondence between the nodes of the parent plan and the lower-level special plans and work plans is established. The core control nodes of the lower-level plan corresponding to each milestone node in the parent plan are clarified, and the node schedule deviation threshold is set (e.g., the milestone node deviation shall not exceed 3 days). After the parent plan node is locked, the lower-level plan node is automatically associated and locked. If adjustments are required, the corresponding node of the parent plan must be approved simultaneously.

[0076] The progress completion rate and delay status of grassroots work plans are automatically mapped and summarized to special plans. The status of special plans are then synchronously mapped to the parent plan, realizing hierarchical linkage feedback of plan execution status. The system automatically generates hierarchical progress comparison reports. Interface mapping is established between plans of different specialties and different systems at the same level, clarifying the connection nodes between specialties and the rules for avoiding cross-operations, so as to avoid conflicts between plans at the same level.

[0077] Structured data modeling and relational database technology are employed to encode and bind planning nodes at each level. Algorithms are used to define the association logic, forming a visual mapping relationship diagram as the linkage mapping rule, supporting visual configuration and modification of the rules. In this embodiment, when nuclear island process standards or project requirements change, the rules can be modified online. Different modes of planning decomposition rules are set, guided by on-site engineering objectives. The rule base is ensured to be updated in real time and synchronously applied to planning decomposition at different levels.

[0078] Furthermore, the entire process of nuclear island installation was streamlined, and the essential prerequisites for each process were determined according to the installation specifications, forming a logical chain of processes. Reversing the order of processes was prohibited, thus establishing process constraint rules. For example, the installation sequence of pipelines was: first, the first stage installation of the main pipe support – the installation of the main pipe – the second stage installation of the main pipe support. This ensured that the decomposed plan complied with nuclear power plant construction management regulations and specifications, resolving delays in plan coordination caused by process conflicts.

[0079] S203, construct the nuclear island installation plan based on the parent plan, process constraint rules, and linkage mapping rules between plans at different levels.

[0080] Optionally, the approved first-level master plan is loaded, locking in the core framework content such as the overall project duration, milestone nodes, and major equipment nodes, clarifying the boundaries and overall control objectives of the plan preparation, and prohibiting the preparation of lower-level plans outside the framework of the master plan. According to the linkage mapping rules, the project management platform decomposes the overall control nodes of the master plan by profession, system, and process, first generating second-level special installation plans for each profession and system, clarifying the start and end times, core nodes, and resource allocation of each sub-project; then, the special plans are further decomposed into third-level work execution plans, detailing the work time, construction teams, equipment use, and quality acceptance links for each single process.

[0081] During the scheduling process, the project management platform automatically verifies the process constraint rules in real time, checking for issues such as reversed processes, resource conflicts, spatial conflicts, and violations of specifications. It automatically intercepts irregular scheduling and provides optimization suggestions. After manual confirmation, the platform completes the correction to ensure that every process meets the constraint requirements.

[0082] According to the linkage mapping rules, the nodes of each level of the plan are bound to each other in both directions, and a linkage link is established between the top-level master plan, the middle-level special plan and the grassroots operation plan. A data synchronization mechanism is set up to realize real-time synchronization of node adjustment, progress feedback and change information between levels, so as to avoid the problems of disconnection of hierarchical plans and data inconsistency, and form a complete multi-level linkage plan system.

[0083] The aforementioned nuclear island installation plan management method integrates rigid specifications and mandatory process constraints into the entire planning process. Automatic system verification eliminates issues prone to occur during manual planning, such as non-compliant procedures, reversed procedures, and missing safety prerequisites, thus mitigating nuclear safety risks at the source. Simultaneously, a two-way linkage planning system, constructed through linkage mapping rules, achieves synchronization of nodes, progress, and changes across levels. Furthermore, the system automatically generates nuclear island installation plans based on the master plan, shortening the plan decomposition cycle from weekly to minute-level. Multi-level planning precisely controls nuclear-grade operational details, ensuring that every nuclear island installation process complies with national nuclear safety standards and international norms, significantly improving the compliance and safety of the installation process and achieving precise and efficient plan management.

[0084] Optionally, in an exemplary embodiment, such as Figure 3 As shown, a method for determining linkage mapping rules and process constraint rules is provided, which specifically includes the following steps:

[0085] S301, based on the nuclear island installation requirements and specifications, determines the planning nodes corresponding to each level of the plan, as well as the dependencies between the planning nodes corresponding to different levels of the plan.

[0086] Among them, the planning node is a key control breakpoint set in the plan at each level. It is the core indicator for measuring the progress of plan execution, judging the status of the process, and triggering upstream and downstream operations.

[0087] Node dependency refers to the logical constraints, triggering associations, and completion condition constraints that exist between planned nodes at different levels or different professions at the same level. That is, the start or completion of one node must be a prerequisite for the completion of one or more other nodes.

[0088] Optionally, guided by the installation requirements of the nuclear island and with the nuclear island installation specifications as the rigid bottom line, the nodes of the multi-level plan are standardized and broken down, the dependency logic between nodes is accurately sorted out, and the problems of arbitrary node settings and ambiguous dependency relationships are eliminated, so as to build a solid foundation for subsequent rules and ensure that every node is compliant and every layer of dependency is clear.

[0089] Specifically, following the principle of "top-down, step-by-step breakdown," planning milestones are set at different levels, ensuring full compliance with pre-defined specifications. For example, in cases where different levels of planning include three levels of technology, the planning milestones for the first level include, but are not limited to, six mandatory milestones: commencement of nuclear island installation, hoisting and placement of the reactor pressure vessel, completion of main pipeline welding, system hydrostatic testing, completion of nuclear island installation, and pre-acceptance handover.

[0090] The second-level planning nodes are divided according to the nuclear island system, and the overall control node is broken down into sub-nodes. For example, "completion of main pipeline welding" is broken down into sub-nodes such as pipeline prefabrication, on-site assembly, welding, non-destructive testing, and heat treatment. The responsibilities, time intervals, and interface specialties of each professional team are clearly defined, and the nodes must meet the process cycle requirements in the specifications.

[0091] The third-level planning nodes need to be broken down to the smallest construction unit. For example, pipeline welding is broken down into single-process nodes such as beveling, wire preheating, layer welding, and visual inspection. The specific personnel qualification requirements (nuclear-level welder certificate), equipment models, operation time, and quality acceptance standards are marked to fully match the process requirements in the preset specifications.

[0092] All planning nodes at all levels are uniquely coded using the rule of "level + system + process + sequence number". For example, the node code for the overall control level is NI-1-001, and the node code for the process level is NI-3-01-005, which facilitates system identification and association. At the same time, the node name, duration, responsible party, and acceptance criteria are entered into the node database to complete standardized archiving and generate a node list for future reference.

[0093] Furthermore, a strong association is established between upper-level and lower-level nodes, clearly defining the overall control layer node as the parent node and the corresponding system layer and process layer nodes as child nodes. Child nodes are prohibited from starting until the parent node is completed. Dependencies can be annotated using two-column tables and logical diagrams, distinguishing between rigid dependencies (non-adjustable) and flexible dependencies (minorly optimizable). Dependencies are automatically checked for violations of preset specifications, generating a dependency report, which is then solidified after review and confirmation by a nuclear safety specialist. For example, Table 1 shows the dependency relationships between different levels of planning nodes provided in this application embodiment.

[0094] Table 1. Dependencies between plan nodes at different levels

[0095]

[0096] S302, construct linkage mapping rules between plans at different levels based on the dependency relationships between plan nodes corresponding to different levels of plans.

[0097] Optionally, the identified qualitative dependencies can be transformed into quantitative, executable digital linkage rules, enabling two-way binding of planning nodes at each level and generating linkage mapping rules. Specifically, strong constraint rules can be set for upper-level nodes on lower-level nodes. When the schedule of an upper-level node is locked, delayed, or advanced, the corresponding lower-level nodes will automatically adjust their schedule thresholds accordingly. After a change to an upper-level node is approved, the associated lower-level nodes will automatically update in batches without requiring manual modification.

[0098] S303, based on the nuclear island installation specifications and the corresponding plan nodes at each level, constructs the process constraint rules for the nuclear island installation process.

[0099] Optionally, based on the nuclear island installation specifications, and combined with the process, safety, and quality requirements of each level of the plan, a full-dimensional process constraint rule can be constructed to clarify the permissible and impermissible boundaries of the nuclear island installation process.

[0100] Specifically, mandatory clauses directly related to the process are extracted from the nuclear island installation specification library and broken down into five categories: process constraints, space constraints, resource constraints, personnel constraints, and quality acceptance constraints. Redundant clauses are eliminated to form a core list of process constraints. For example, nuclear-grade welding must be performed by certified welders, ventilation testing is required before working in confined spaces, and the accuracy deviation of equipment installation must not exceed 0.1mm.

[0101] Furthermore, based on the construction technology corresponding to each level of the plan nodes, sequential constraints are set to strictly prohibit the reversal of procedures. For example, equipment must be placed first, followed by pipeline connection; non-destructive testing must be performed first, followed by system pressure testing; and single-machine commissioning must be performed first, followed by system commissioning. All process constraints must match the process route requirements in the specifications.

[0102] Various constraint rules are transformed into built-in verification logic within the engineering management platform and embedded in the planning and construction assignment modules to achieve dual verification: First, during the planning stage, the system automatically verifies whether the arrangement of node procedures violates constraints; if violations occur, a warning is displayed and a correction plan is suggested. Second, during the construction execution stage, before a procedure is submitted for work, the system verifies whether the qualifications, resources, and pre-acceptance standards are met; if not, the submission for work is prohibited. Typical nuclear island procedures (such as reactor equipment installation and main pipeline welding) are selected for rule testing to verify the effectiveness of constraints and ensure that no non-compliant procedures can bypass control. After the test is passed, a procedure constraint rule document is generated and archived along with linkage rules and node lists as the core basis for nuclear island installation construction and quality supervision.

[0103] In this embodiment, all planned node settings and process arrangements strictly adhere to the nuclear island installation specifications. The process constraint rules directly implement mandatory nuclear safety requirements. Through rigid system interception, problems such as process reversal, illegal construction, and unqualified qualifications that are prone to occur in manual arrangement are completely eliminated. Every process and every node has a standard basis, and the whole process is traceable and supervised, minimizing potential safety and quality hazards in nuclear island installation and meeting nuclear safety regulatory requirements.

[0104] Optionally, in one embodiment, such as Figure 4 As shown, a method for constructing a nuclear island installation plan is provided, which specifically includes the following steps:

[0105] S401, For each level, construct the hierarchical plan for that level based on the hierarchical plan of the previous level, the linkage mapping rules between the hierarchical plan of this level and the hierarchical plan of the previous level, and the process constraint rules.

[0106] In the case of changing the level to the second level, the level plan of the previous level is the parent plan.

[0107] Optionally, for the second level, the engineering management platform automatically retrieves the linkage mapping rules based on the second-level hierarchical plan and automatically generates a task list for the second-level hierarchical plan of the nuclear island installation, including a work package list, schedule window, process constraint relationships, and resource requirements, without the need for manual intervention.

[0108] Furthermore, based on the generated second-level hierarchical plan, the linkage mapping rules are invoked to automatically generate the third-level hierarchical plan, specifying the operation time, construction team, and resource allocation for each process. Each level is performed sequentially, and the hierarchical plan for the final level of the unit is generated.

[0109] S402, construct the nuclear island installation plan according to the hierarchical plan at each level.

[0110] Optionally, the project management platform automatically collects all effective first-level (master), second-level (sub-) and third-level (process) plans, verifies whether nodes between levels are fully bound, whether linkage rules are fully adapted, whether process constraints are fully met, and whether data standards are consistent (work period unit, node code, responsible entity), and investigates data conflicts, node omissions, and interface mismatches, generating a collection and verification report.

[0111] Furthermore, in accordance with the linkage mapping rules, the data transmission links of the three-level plan are connected, and a full-link association is established between the parent node, the branch node, and the process node to achieve three major linkages: when the upper-level plan changes, the lower-level plan is automatically synchronized; when the lower-level process is completed, the upper-level node automatically updates its progress; when a node is abnormally delayed, the entire link triggers a graded early warning, forming a closed-loop linkage system.

[0112] In this embodiment, all hierarchical plans are generated under the dual constraints of linkage mapping rules and process constraint rules, fully conforming to nuclear island installation specifications and nuclear safety requirements. Each plan and each node has upper-level basis and rule support, avoiding nuclear safety hazards from the source of plan preparation, meeting the mandatory requirements of nuclear safety supervision, and reducing the incidence of quality defects and safety accidents.

[0113] Optionally, in one embodiment, such as Figure 5 As shown, a method for installing a nuclear island is provided, which specifically includes the following steps:

[0114] S501 verifies the correctness of the completed plans at each level.

[0115] Optionally, the correctness of the completed hierarchical plans at each level can be verified to check for issues related to plan compliance, logical rationality, linkage accuracy, and on-site feasibility, ensuring that all plan content fully conforms to nuclear power specifications and actual construction practices.

[0116] The verification work is jointly carried out by the planning engineer, nuclear safety specialist, supervising engineer, and on-site construction manager, and adopts a dual mode of "automatic system verification + manual review verification" to cover all planning content at all levels.

[0117] S502, if the verification passes, sends process-level operation instructions to the equipment at the nuclear power plant work site.

[0118] Among them, the process-level work instructions are used to guide the workers at the work site to install the nuclear island.

[0119] Optionally, the instruction issuance process can only be triggered if the correctness verification of each level of plan is passed. The process-level work instructions are directly converted and generated from the third-level process work plan, accurately connecting with the on-site work terminal to achieve seamless connection between "plan-instruction-construction", with full digital traceability, guiding the operators to carry out nuclear island installation work in a standardized manner.

[0120] Based on the verified work plan at the process level, and aligned with the digital construction production platform, the system automatically breaks down and generates individual work instructions. Each instruction corresponds to a specific nuclear island installation process and contains complete work information. Optionally, the process-level work instructions can be precisely distributed to corresponding terminal devices on the work site through a dedicated digital network at the nuclear power plant site. These include on-site construction tablets, handheld terminals for work teams, large machinery control terminals, and on-site electronic display screens, enabling targeted instruction delivery, visibility to all personnel, and access at any time.

[0121] After receiving instructions through the terminal equipment, on-site workers strictly follow the received process-level instructions to carry out installation work. The terminal can retrieve instruction details, process specifications, and acceptance standards at any time. After the work is completed, the workers submit completion feedback and quality acceptance applications through the terminal. The acceptance results are simultaneously transmitted back to the plans at each level, and the plan execution progress is automatically updated.

[0122] In this embodiment, by verifying the correctness of plans at each level, logical errors and other problems in the plans can be identified and eliminated in advance before the plans are executed, ensuring that the nuclear island installation plan is accurate, reliable and executable, and avoiding construction risks, rework and safety hazards caused by planning errors from the source.

[0123] Optionally, in one embodiment, such as Figure 6 As shown, a method for early warning of construction deviations is provided, which specifically includes the following steps:

[0124] S601 collects actual work progress data at the work site during the nuclear island installation process.

[0125] Among them, the actual work progress data is quantitative and status data that reflects the actual progress of work processes during the entire construction process at the nuclear island installation site, obtained through on-site data collection equipment, manual reporting, and terminal feedback. It is the core basis for measuring the execution of the plan.

[0126] Optionally, after completing a work process, workers can scan the process QR code using a construction tablet or handheld terminal to fill in the actual start / completion time, completion rate, and acceptance status. The terminal automatically uploads the data to the digital platform, eliminating the need for manual offline recording. Positioning terminals and progress monitoring sensors can also be deployed on the nuclear island site to monitor personnel arrival, machinery operation, and equipment placement progress in real time, automatically generating quantitative progress data and reducing manual data entry. Nuclear-grade process acceptance data is uploaded synchronously through quality inspection terminals, linking it to the corresponding process progress. The engineering management platform performs preliminary verification of the collected data, checking for missing data and logical anomalies (such as completion time earlier than start time), marking abnormal data and pushing it to the data collector for correction within a specified timeframe, ensuring the accuracy and validity of the data entered into the database.

[0127] S602, when it is determined that there is a planning deviation between the actual work progress data and the hierarchical plan at the last level, determine the degree of impact of the planning deviation on the hierarchical plans at other levels.

[0128] Among them, the plan deviation is the difference between the actual progress data of the last-level process-level operation and the planned progress of the corresponding level plan, and is divided into two categories: ahead of schedule and behind schedule. The degree of impact is the magnitude of the impact of the schedule deviation occurring in the last-level plan on the second-level professional / system sub-plan and the first-level master control plan, which is transmitted upward through the inter-level linkage mapping rules.

[0129] Optionally, the project management platform retrieves the bound end-level process-level plan data and compares it item by item with the real-time collected actual progress data to calculate the schedule deviation value and completion rate deviation value. The project management platform presets normal deviation thresholds. If the deviation is within the threshold, it is determined as normal construction fluctuation and no further analysis is required; if the deviation exceeds the threshold, it is determined as an abnormal plan deviation, and the project management platform automatically locks the deviation process, deviation duration, and responsible team, and initiates the deviation impact analysis process.

[0130] Furthermore, the previously established hierarchical linkage mapping rules are invoked to trace all upper-level plan nodes and cross-professional related processes along the link of "last process level → second-level sub-plan → first-level master plan". A deviation impact analysis report is automatically generated, which clarifies the deviation details, transmission path, impact level, impact grade, and potential risks. The report is then pushed to the planning management department and the on-site manager for review and confirmation.

[0131] S603 provides early warning of construction deviations based on the degree of impact of planning deviations on other levels of planning.

[0132] Optionally, a corresponding warning level can be matched based on the degree of impact of the deviation, and the warning information can be accurately pushed to the corresponding level of management personnel. The correspondence between warning levels and impact can be fixed in advance on the project management platform, and the warning method, target audience, and warning time limit can be clearly defined.

[0133] For example, taking a multi-level system including three levels, the first level is the fourth level in the nuclear power engineering plan, the second level is the fifth level, and the third level is the sixth level. The deviation between the sixth-level process and the fifth-level task can be calculated in the following way.

[0134] A single Level 5 task includes The formula for calculating the comprehensive deviation of each level 6 process is as follows:

[0135]

[0136] in, This represents a planning deviation for a Level 5 task. The sixth level mission Actual planned deviation of each process A positive number indicates a lag. A negative number indicates an advance payment; The sixth level mission The influence coefficient of a level 6 process on its corresponding level 5 plan ranges from 0 to 1, and is set based on the process importance / process weight. If The task is deemed to be lagging behind at level 5; if The level 5 task was determined ahead of schedule.

[0137] Furthermore, the deviation from Level 5 to Level 4 tasks is calculated as follows. A single Level 4 milestone contains... The formula for calculating the overall deviation of each Level 5 task is as follows:

[0138]

[0139] like This triggers a risk warning for management costs; For the first The impact coefficient of a Level 5 task on its corresponding Level 4 plan ranges from 0 to 1, determined based on the task's weight in the milestone; the warning level is based on... The absolute value and the percentage of the remaining time for each milestone are determined.

[0140] Furthermore, in the embodiments of this application, as shown in Table 2, there is a schematic table of deviation warning levels.

[0141] Table 2 Deviation Warning Classification

[0142]

[0143] in, The remaining construction period for the fourth-level plan.

[0144] Furthermore, if a discrepancy is found between the actual work progress data and the plan at the last level, adjustments will be made to the plans at other levels. Optionally, adjustments must strictly adhere to the hierarchical linkage mapping rules; it is strictly prohibited to deviate from the linkage logic or modify a single level of the plan independently, and adjustments must be made to prevent hierarchical disconnects and node conflicts. Core milestone nodes and nuclear safety-critical process nodes in the parent plan are rigid nodes and, in principle, should not be adjusted. Only optimization of process arrangement and allocation of resources to compensate for deviations are permitted. If adjustments to rigid nodes are necessary, a joint approval process involving the owner, supervisor, and relevant nuclear safety departments must be followed.

[0145] Specifically, when a plan deviation is detected at the last level (level 6 process plan) and an alert is triggered, the engineering management platform automatically generates corresponding adjustment suggestions for the next higher level (level 5 plan) based on preset linkage mapping rules and the scope of the deviation's impact. These adjustment suggestions include, but are not limited to, changing construction work packages, extending work hours, adjusting work shifts, and optimizing process layout. After the management personnel approve the adjustment suggestions, the system updates the level 5 plan in real time and simultaneously corrects all level 6 process plans associated with that level 5 plan. At the same time, the adjusted process-level work instructions are immediately sent to the work site team terminals to achieve rapid closed-loop correction of deviations.

[0146] When milestone nodes in the upper-level (Level 4 milestone plan) are adjusted earlier or later due to project needs, the project management platform automatically transmits the adjustment information downwards according to the inter-level linkage mapping rules: First, the schedule window of the corresponding Level 5 plan is adjusted in real time, and then the changes in the Level 5 plan are automatically transmitted to the Level 6 process-level plan. The process operation time, operation sequence, and resource allocation are redistributed and adapted to ensure that the Level 4, Level 5, and Level 6 plans are always consistent and synchronized in terms of nodes, schedules, and logic, avoiding hierarchical disconnect and node conflicts.

[0147] During the aforementioned top-down or bottom-up planning adjustments, the engineering management platform invokes preset resource and process constraint rules in real time to automatically verify the adjusted plan. Verification includes: construction space conflict verification, large machinery resource conflict verification, personnel allocation conflict verification, nuclear island installation process constraint verification, and preceding / following process logic verification. If the verification fails, the engineering management platform prohibits the adjustment plan from taking effect and returns a conflict warning until a feasible adjustment plan without resource conflicts, space limitations, and meeting process requirements is formed, ensuring the executability and construction safety of the adjusted plan. This achieves two-way linkage, with lower-level deviations fed back upwards and upper-level changes transmitted downwards, ensuring that multi-level plans are always synchronized and avoiding hierarchical disconnect.

[0148] In this embodiment, by collecting on-site progress data in real time, deviations can be detected and judged early, replacing the traditional model of manual periodic reporting and delayed statistics. This avoids the accumulation of minor construction deviations into major project delays. It also accurately predicts the transmission effect of deviations on upper-level plans, provides early warnings and interventions, and effectively ensures that key milestones in nuclear island installation and the overall project schedule are achieved on time, avoiding economic losses and production delays caused by project delays.
