[0075] The nuclear power plant piping network layout method, apparatus, electronic equipment, and storage medium according to the embodiments of this application have at least the following beneficial effects:

[0076] This application provides a method for nuclear power plant pipeline layout. It first establishes an initial pipeline layout strategy, objective function, constraints, and update conditions, laying the foundation for subsequent optimization. The objective function clarifies the optimization goals, such as minimizing pipe length, number of bends, and number of intersections, as well as maximizing safety and ease of maintenance. Strategy constraints ensure that the pipeline layout must meet physical, safety, and spatial limitations. Strategy update conditions define the conditions under which the current strategy needs to be updated to drive continuous improvement. Next, the initial pipeline layout strategy is evaluated for rationality based on the objective function and constraints, yielding first strategy evaluation information. This evaluation step determines whether the initial strategy meets the optimization objectives and constraints, thus determining whether it is a feasible starting point. If the initial strategy evaluation result is unsatisfactory, further optimization is required. Then, a set of domain strategies matching the current pipeline layout strategy is obtained. This set contains multiple domain layout strategies, which may originate from historical data, expert experience, or existing successful cases, providing diverse options for strategy optimization. A domain-specific layout strategy is selected from the set of domain strategies as a candidate pipeline layout strategy, introducing a new strategy to explore better solutions. The candidate pipeline layout strategy undergoes a rationality evaluation, yielding second strategy evaluation information. This step aims to verify whether the candidate strategy is more advantageous than the initial strategy and whether it is closer to the optimization objective. By comparing the first and second strategy evaluation information, if they meet preset strategy update conditions, such as the candidate strategy outperforming the initial strategy on certain key indicators, then an updated pipeline layout strategy is determined between the initial and candidate strategies. This marks a step forward in the strategy optimization iteration. Subsequently, the evaluation process is repeated based on the updated pipeline layout strategy. This cycle continues until preset strategy optimization conditions are met, such as reaching the maximum number of iterations or the strategy performance no longer showing significant improvement. Finally, when the optimization conditions are met, the current pipeline layout strategy is determined as the target pipeline layout strategy, i.e., the optimal or near-optimal solution. Through the above process, this method can continuously evaluate, select, update and iterate, gradually approaching the optimal pipeline layout scheme, and finally find a more reasonable pipeline layout strategy to perform nuclear power plant pipeline layout operations on the target nuclear power plant, thereby improving the design efficiency, economy and safety of nuclear power plants, while reducing human error and improving the level of intelligence in engineering design.

[0096] As a key component of modern energy systems, the safety and efficiency of nuclear power plants in their design and operation are of paramount importance. In the design and construction of nuclear power plants, process piping layout is a critical aspect, involving the transmission and distribution of various fluids within the plant, and also affecting the overall system safety, ease of maintenance, and cost-effectiveness. However, the piping layout problem in nuclear power plants, due to its complex constraints and diverse optimization objectives, has become a major challenge in engineering design.

[0097] Traditional piping layout methods rely heavily on engineers' experience and manual operation, which presents numerous problems.

[0098] First, traditional pipeline layout methods struggle to find the optimal layout while meeting the required constraints, potentially leading to suboptimal design, increased construction and maintenance costs, and even impacting the safe operation of nuclear power plants.

[0099] Secondly, traditional methods have difficulties in space utilization. Nuclear power plants have limited internal space, and traditional layout methods cannot make full use of the space.

[0100] Furthermore, nuclear power plant piping systems are complex, with numerous pipelines, making them prone to collisions and interference between pipelines or with other equipment. Traditional methods also struggle to balance multi-objective optimization requirements, such as cost, safety, and reliability.

[0101] At the same time, traditional methods also have shortcomings in dealing with the complex constraints in the design of nuclear power plant process piping networks, such as nuclear safety regulations, radiation protection standards, and pipe material characteristics.

[0102] Finally, traditional pipeline layout design methods are inefficient, prone to human error, and lead to extended design cycles.

[0103] In summary, traditional methods for nuclear power plant piping layout present challenges in areas such as space utilization, collisions, multi-objective optimization, handling complex constraints, and design efficiency, necessitating a more efficient optimization approach to address these challenges.

[0104] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a method and apparatus for nuclear power plant piping layout, electronic equipment, and storage medium, which can find a more reasonable piping layout strategy to perform nuclear power plant piping layout operations on a target nuclear power plant.

[0105] The following explanation is based on the accompanying drawings.

[0106] Reference Figure 1 The nuclear power plant piping layout method according to the embodiments of this application may include:

[0107] Step S101: Obtain the initial pipeline layout strategy, strategy objective function, strategy constraints, and strategy update conditions;

[0108] Step S102: Based on the strategy objective function and strategy constraints, evaluate the rationality of the pipeline layout strategy to obtain the first strategy evaluation information;

[0109] Step S103: Obtain the set of domain strategies that match the pipeline network layout strategy; wherein, the set of domain strategies includes multiple domain layout strategies corresponding to the pipeline network layout strategy.

[0110] Step S104: Select a domain deployment strategy from the domain strategy set as a candidate pipeline deployment strategy;

[0111] Step S105: Based on the strategy objective function and strategy constraints, evaluate the rationality of the candidate pipeline layout strategy to obtain the second strategy evaluation information.

[0112] Step S106: In response to the first strategy evaluation information and the second strategy evaluation information satisfying the strategy update conditions, an updated pipeline layout strategy is determined between the pipeline layout strategy and the candidate pipeline layout strategy.

[0113] Step S107: Based on the updated pipeline layout strategy, return to the execution of the rationality evaluation of the pipeline layout strategy based on the strategy objective function and strategy constraints until the preset strategy optimization conditions are met, and determine the pipeline layout strategy as the target pipeline layout strategy.

[0114] Step S108: Perform nuclear power plant pipeline layout operations according to the target pipeline layout strategy.

[0115] In some embodiments, step S101 involves obtaining the initial pipeline layout strategy, strategy objective function, strategy constraints, and strategy update conditions.

[0116] It is important to note that obtaining the initial pipeline layout strategy, along with its associated objective function, constraints, and update conditions, is crucial, as it lays the foundation for the entire optimization process. The initial pipeline layout strategy can be based on historical data, existing design specifications, or expert experience. The objective function explicitly defines the goals to be pursued during optimization, such as minimizing the total pipeline length, reducing the number of bends and intersections, while maximizing safety and ease of maintenance. Strategy constraints ensure that any generated strategy must meet the physical and safety limitations of the nuclear power plant; for example, pipelines cannot pass through equipment, must meet specific bending radii, and comply with nuclear safety regulations. The strategy update conditions specify when the current strategy needs to be updated, such as when a better strategy is discovered, or when the strategy no longer improves on certain key performance indicators.

[0117] Reference Figure 2 According to some embodiments of this application, step S101, obtaining the initial pipeline layout strategy, strategy objective function, strategy constraints, and strategy update conditions, may include:

[0118] Step S201: Obtain the initial pipeline layout strategy, strategy objective function, and strategy update conditions;

[0119] Step S202: Obtain pipeline space limitation information, pipeline spacing limitation information, and pipeline connection limitation information for the target nuclear power plant regarding pipeline planning;

[0120] Step S203: Obtain the engineering specification benchmark information and safety standard information corresponding to the target nuclear power plant;

[0121] Step S204: Construct spatial constraint sub-conditions based on pipeline space limitation information;

[0122] Step S205: Construct physical constraint sub-conditions based on engineering specification benchmark information;

[0123] Step S206: Construct security constraint sub-conditions based on security standard information;

[0124] Step S207: Construct spacing constraint sub-conditions based on pipe spacing limit information;

[0125] Step S208: Construct connection constraint sub-conditions based on pipeline connection constraint information;

[0126] Step S209: Integrate the spatial constraint sub-conditions, physical constraint sub-conditions, security constraint sub-conditions, spacing constraint sub-conditions, and connection constraint sub-conditions into policy constraint conditions.

[0127] In some embodiments, step S201 involves obtaining the initial pipeline layout strategy, the strategy objective function, and the strategy update conditions.

[0128] It's important to note that this involves obtaining the initial pipeline layout strategy, the strategy objective function, and the strategy update conditions. The initial pipeline layout strategy may be based on historical data, existing design specifications, or expert experience. The strategy objective function defines the specific optimization objectives, such as minimizing the total pipeline length, reducing the number of bends and intersections, while maximizing safety and ease of maintenance. The strategy update conditions specify under what circumstances the current strategy needs to be updated, such as when a better strategy is discovered, or when the strategy no longer improves key performance indicators.

[0129] In some embodiments, step S202 involves obtaining pipeline space limitation information, pipeline spacing limitation information, and pipeline connection limitation information for the target nuclear power plant regarding pipeline planning.

[0130] It is important to note that obtaining information regarding the target nuclear power plant's piping network planning, including spatial constraints, pipe spacing constraints, and pipe connection constraints, is crucial for understanding the plant's physical layout and design requirements. Spacing constraints define the areas where pipes can be laid, pipe spacing constraints specify the minimum distance that must be maintained between pipes, and pipe connection constraints ensure that both ends of the pipes can be accurately connected to designated equipment or nodes.

[0131] In some embodiments, step S203 involves obtaining engineering specification benchmark information and safety standard information corresponding to the target nuclear power plant;

[0132] It is important to note that it is necessary to obtain the engineering specification benchmark information and safety standard information corresponding to the target nuclear power plant. The engineering specification benchmark information provides the technical specifications that must be followed in the design and layout of pipelines, such as the bending radius, diameter, and material requirements of the pipelines. The safety standard information ensures that the pipeline layout meets the safety requirements of the nuclear power plant, including radiation protection, fire protection, explosion protection, and earthquake resistance.

[0133] In some embodiments, steps S204 to S208 involve constructing spatial constraint sub-conditions based on pipeline space limitation information; constructing physical constraint sub-conditions based on engineering specification benchmark information; constructing safety constraint sub-conditions based on safety standard information; constructing spacing constraint sub-conditions based on pipeline spacing limitation information; and constructing connection constraint sub-conditions based on pipeline connection limitation information.

[0134] It should be noted that steps S204 to S208 construct corresponding constraint sub-conditions based on this information. Step S204 constructs spatial constraint sub-conditions based on pipeline space limitation information to ensure that pipelines are arranged within the predetermined space. Step S205 constructs physical constraint sub-conditions based on engineering specification benchmark information to ensure that the physical characteristics of the pipelines comply with engineering design specifications. Step S206 constructs safety constraint sub-conditions based on safety standard information to ensure that the pipeline arrangement meets the safety standards of nuclear power plants. Step S207 constructs spacing constraint sub-conditions based on pipeline spacing limitation information to prevent interference between pipelines. Step S208 constructs connection constraint sub-conditions based on pipeline connection limitation information to ensure that pipelines can be correctly connected to designated equipment or nodes.

[0135] In some embodiments, step S209 integrates the spatial constraint sub-conditions, physical constraint sub-conditions, security constraint sub-conditions, spacing constraint sub-conditions, and connection constraint sub-conditions into a strategy constraint condition.

[0136] It should be noted that the constructed spatial constraint sub-conditions, physical constraint sub-conditions, safety constraint sub-conditions, spacing constraint sub-conditions, and connectivity constraint sub-conditions are integrated into strategy constraint conditions. This step unifies various constraint conditions, forming a comprehensive constraint framework to guide the subsequent pipeline layout strategy optimization process. In this way, it is ensured that the generated pipeline layout strategy not only achieves the optimization objectives but also meets the stringent physical, engineering, and safety requirements of nuclear power plants.

[0137] In step S102 of some embodiments, the rationality of the pipeline layout strategy is evaluated based on the strategy objective function and strategy constraints to obtain the first strategy evaluation information.

[0138] It should be noted that, based on the strategic objective function and constraints, a rationality assessment of the initial pipeline layout strategy is conducted to obtain the first strategy assessment information. This step is a comprehensive review of the initial strategy, aiming to determine whether it meets the established optimization objectives and constraints. The assessment may involve calculating the total pipeline length, counting the number of bends and intersections, and evaluating safety and maintenance convenience indicators. Through this assessment, it can be determined whether the initial strategy is a feasible starting point or whether significant adjustments are needed.

[0139] Reference Figure 3 According to some embodiments of this application, the strategy objective function includes a sub-function for the total length of the pipeline network, a sub-function for the total number of bends, and a sub-function for the total number of intersections. Step S102, based on the strategy objective function and strategy constraints, evaluates the rationality of the pipeline network layout strategy to obtain first strategy evaluation information, which may include:

[0140] Step S301: Determine the pipeline quantity parameters, pipeline length parameters, elbow quantity parameters, and intersection point parameters that conform to the pipeline layout strategy.

[0141] Step S302: Substitute the pipeline quantity parameter and the pipeline length parameter corresponding to each pipeline into the pipeline network total length sub-function, and solve the pipeline network total length sub-function based on the strategy constraints to obtain pipeline network length evaluation information;

[0142] Step S303: Substitute the pipe quantity parameter and the elbow quantity parameter corresponding to each pipe into the elbow total number sub-function, and solve the elbow total number sub-function based on the strategy constraint to obtain the elbow total number evaluation information.

[0143] Step S304: Substitute the pipe quantity parameter and the number of intersection points between each pair of adjacent pipes into the total number of intersection points sub-function to obtain the total number of intersection points evaluation information;

[0144] Step S305: Integrate the pipeline length assessment information, the total number of bends assessment information, and the total number of intersections assessment information to obtain the first strategy assessment information.

[0145] In some embodiments of this application, the strategy objective function covers multiple aspects such as the total length of the pipeline network, the total number of bends, and the total number of intersections. By comprehensively evaluating these sub-functions, the rationality of the pipeline network layout strategy can be evaluated, thereby obtaining the first strategy evaluation information.

[0146] In some embodiments, step S301 involves determining the number of pipes conforming to the pipeline layout strategy, the pipe length parameter and the number of bends corresponding to each pipe, and the number of intersections between each pair of adjacent pipes.

[0147] It is important to note that determining the number of pipes conforming to the pipeline layout strategy, the pipe length and number of bends for each pipe, and the number of intersections between adjacent pipes is crucial. This step forms the foundation of the entire assessment and requires accurately extracting key parameter information from the current pipeline layout strategy. These parameters will be directly used in subsequent sub-function calculations, and their accuracy directly impacts the reliability of the assessment results.

[0148] In step S302 of some embodiments, the number of pipes and the pipe length parameter corresponding to each pipe are substituted into the total length sub-function of the pipeline network, and the total length sub-function of the pipeline network is solved based on the policy constraints to obtain the pipeline network length evaluation information.

[0149] It should be noted that the pipeline quantity parameter and the corresponding pipeline length parameter for each pipeline are substituted into the total pipeline length subfunction, and the total pipeline length subfunction is solved based on the strategy constraints to obtain the pipeline length evaluation information. Here, the purpose of the total pipeline length subfunction is to evaluate the rationality of the total pipeline length under the current strategy, as the total pipeline length is one of the important factors affecting cost and pressure loss. By solving this subfunction, it can be determined whether the current strategy has achieved the optimization objective in terms of pipeline length, while ensuring that strategy constraints, such as space limitations and connection requirements, are met.

[0150] In step S303 of some embodiments, the number of pipes and the number of bends corresponding to each pipe are substituted into the total number of bends sub-function, and the total number of bends sub-function is solved based on the strategy constraints to obtain the total number of bends evaluation information.

[0151] It should be noted that the total number of bends is determined by substituting the pipe quantity parameter and the corresponding elbow quantity parameter for each pipe into the elbow total subfunction, and then solving the elbow total subfunction based on the strategy constraints. The number of elbows directly affects the complexity and pressure loss of the piping system; too many elbows can lead to maintenance difficulties and reduced energy efficiency. Therefore, this evaluation step aims to verify whether the current strategy effectively reduces unnecessary elbows while ensuring compliance with engineering specifications and safety standards.

[0152] In step S304 of some embodiments, the number of pipes and the number of intersections between each pair of adjacent pipes are substituted into the total number of intersections sub-function to obtain the total number of intersections evaluation information;

[0153] It should be noted that the total number of intersections is determined by substituting the parameters for the number of pipes and the number of intersections between each pair of adjacent pipes into the total number of intersections subfunction. The number of intersections is a crucial factor affecting installation and maintenance convenience; too many intersections increase construction difficulty and maintenance costs. This evaluation step allows us to determine whether the current strategy has effectively reduced pipe intersections and optimized the space utilization and accessibility of the pipe layout.

[0154] In some embodiments, step S305 integrates the pipeline length assessment information, the total number of bends assessment information, and the total number of intersections assessment information to obtain the first strategy assessment information.

[0155] It should be noted that the assessment information of pipeline length, total number of bends, and total number of intersections are integrated to obtain the first strategy assessment information. This step is a comprehensive analysis of the assessment results of the preceding sub-functions. By integrating this information, the rationality of the current pipeline layout strategy can be comprehensively evaluated. This integration not only considers the optimization degree of each sub-objective but also ensures that the strategy constraints are met, thus providing a comprehensive evaluation basis for subsequent strategy updates and optimizations.

[0156] Reference Figure 4 According to some embodiments of this application, the strategy objective function further includes a safety assessment sub-function. Step S102, based on the strategy objective function and strategy constraints, evaluates the rationality of the pipeline layout strategy to obtain first strategy assessment information, and may further include:

[0157] Step S401: Conduct a safety assessment for each pipeline and obtain the corresponding safety score;

[0158] Step S402: Substitute the safety score corresponding to each pipeline into the safety assessment sub-function to obtain the pipeline network safety assessment information;

[0159] In step S305, the pipeline length assessment information, the total number of bends assessment information, and the total number of intersections assessment information are integrated to obtain the first strategy assessment information, which may include:

[0160] Step S403: Integrate the pipeline length assessment information, the total number of bends assessment information, the total number of intersections assessment information, and the pipeline safety assessment information to obtain the first strategy assessment information.

[0161] In some embodiments of this application, the strategy objective function is further extended to include a safety assessment subfunction, thereby enabling a comprehensive consideration of safety factors when evaluating the rationality of pipeline layout strategies.

[0162] In some embodiments, step S401 involves performing a safety assessment for each pipe to obtain a corresponding safety score.

[0163] It is important to note that a safety assessment is conducted for each pipeline to obtain a corresponding safety score. This step is crucial because it directly relates to the safe operation of the nuclear power plant, requiring a comprehensive consideration of factors such as pipeline material, diameter, pressure rating, surrounding environment, and potential risks related to radiation, fire, and explosion. By conducting a detailed safety assessment of each pipeline, the safety of each pipeline can be quantified, providing data support for subsequent calculations of safety assessment sub-functions.

[0164] In step S402 of some embodiments, the safety score corresponding to each pipeline is substituted into the safety assessment sub-function to obtain pipeline safety assessment information;

[0165] It should be noted that the safety score corresponding to each pipeline is substituted into the safety assessment subfunction to obtain the pipeline network safety assessment information. This step integrates the safety of individual pipelines into the entire pipeline network system, evaluating the performance of the entire pipeline network layout strategy at the safety level. The design of the safety assessment subfunction aims to ensure that the pipeline network layout is not only economically and technically feasible, but also meets safety standards and complies with the stringent regulatory requirements of nuclear power plants.

[0166] In step S403 of some embodiments, the pipeline length assessment information, the total number of bends assessment information, the total number of intersections assessment information, and the pipeline safety assessment information are integrated to obtain the first strategy assessment information.

[0167] It should be noted that this embodiment extends step S305 by integrating pipeline length assessment information, total number of bends assessment information, total number of intersections assessment information, and newly added pipeline safety assessment information to ultimately obtain the first strategy assessment information. This step emphasizes that when evaluating pipeline layout strategies, not only should conventional indicators such as economic benefits and layout optimization be considered, but safety should also be taken as one of the core considerations. Through this comprehensive assessment method, it can be ensured that the obtained pipeline layout strategy meets both economic and technical requirements while also complying with the high safety standards of nuclear power plants, thereby providing a guarantee for the stable and reliable operation of nuclear power plants.

[0168] Reference Figure 5 According to some embodiments of this application, the strategy objective function further includes a maintenance evaluation sub-function. Step S102, based on the strategy objective function and strategy constraints, evaluates the rationality of the pipeline layout strategy to obtain first strategy evaluation information, and may further include:

[0169] Step S501: Conduct a maintenance convenience assessment for each pipeline and obtain the corresponding maintenance convenience score;

[0170] Step S502: Substitute the convenience score corresponding to each pipeline into the maintenance assessment sub-function to obtain pipeline maintenance assessment information;

[0171] In step S305, the pipeline length assessment information, the total number of bends assessment information, and the total number of intersections assessment information are integrated to obtain the first strategy assessment information, which may include:

[0172] Step S503: Integrate the pipeline length assessment information, the total number of bends assessment information, the total number of intersections assessment information, and the pipeline maintenance assessment information to obtain the first strategy assessment information.

[0173] In some embodiments of this application, the strategy objective function is further expanded to include a maintenance evaluation subfunction, thereby enabling a comprehensive consideration of maintenance convenience when evaluating the rationality of pipeline layout strategies.

[0174] In some embodiments, step S501 involves performing a maintenance ease assessment for each pipeline to obtain a corresponding maintenance ease score.

[0175] It should be noted that a maintenance accessibility assessment is conducted for each pipeline, resulting in a corresponding maintenance accessibility score. The assessment primarily focuses on factors such as pipeline accessibility, operability, and the manpower and time costs required for maintenance. By conducting a detailed maintenance accessibility assessment for each pipeline, the maintenance performance of each pipeline can be quantified, providing data support for subsequent calculations of maintenance assessment sub-functions.

[0176] In step S502 of some embodiments, the convenience score corresponding to each pipeline is substituted into the maintenance evaluation sub-function to obtain pipeline maintenance evaluation information;

[0177] It should be noted that the maintenance accessibility score for each pipeline is substituted into the maintenance assessment subfunction to obtain the pipeline network maintenance assessment information. This step integrates the maintenance accessibility of individual pipelines into the entire pipeline network system, evaluating the performance of the entire pipeline layout strategy in terms of maintenance accessibility. The design of the maintenance assessment subfunction aims to ensure that the pipeline network layout is not only economically and technically feasible, but also provides convenience for maintenance operations, reducing maintenance costs and time, and improving the operating efficiency of the nuclear power plant.

[0178] In some embodiments, step S503 integrates the pipeline length assessment information, the total number of bends assessment information, the total number of intersections assessment information, and the pipeline maintenance assessment information to obtain the first strategy assessment information.

[0179] It should be noted that the first strategy assessment information is obtained by integrating the pipeline length assessment information, the total number of bends assessment information, the total number of intersections assessment information, and the newly added pipeline maintenance assessment information. This step emphasizes that when assessing pipeline layout strategies, not only should conventional indicators such as economic benefits and layout optimization be considered, but also maintenance convenience should be taken as one of the core considerations. Through this comprehensive assessment method, it can be ensured that the obtained pipeline layout strategy not only meets economic and technical requirements, but also facilitates future inspection, maintenance, and repair work, thereby providing a guarantee for the long-term stable operation of the nuclear power plant.

[0180] In step S103 of some embodiments, a set of domain strategies matching the pipeline layout strategy is obtained; wherein, the set of domain strategies includes multiple domain layout strategies corresponding to the pipeline layout strategy.

[0181] It should be noted that this stage involves obtaining a set of domain strategies that match the current pipeline layout strategy. This set of domain strategies includes multiple different domain layout strategies, which can be derived from historical cases, expert knowledge, or other successful design solutions. These strategies provide diverse options for the optimization process, increasing the likelihood of finding a better solution.

[0182] Reference Figure 6 According to some embodiments of this application, step S103, obtaining a set of domain strategies matching the pipeline layout strategy, may include:

[0183] Step S601: Configure the initial search activity for the pipeline layout strategy;

[0184] Step S602: Adjust the pipeline layout strategy based on search activity to obtain multiple domain layout strategies;

[0185] Step S603: Integrate the multiple domain deployment strategies to obtain a domain strategy set.

[0186] In some embodiments, step S601 configures an initial search activity for the pipeline layout strategy;

[0187] It's important to note that an initial search activity level should be configured for the current pipeline layout strategy. This search activity level can be seen as a control parameter, guiding the extent of subsequent exploration for strategy adjustments. Higher search activity means broader exploration, potentially leading to more diverse area layout strategies, while lower activity may result in more focused and refined adjustments. This initial value can be set based on historical experience, expert knowledge, or the results of a preliminary analysis of the current strategy.

[0188] In some implementation steps, step S602 involves adjusting the pipeline layout strategy based on search activity to obtain multiple domain layout strategies.

[0189] It should be noted that the current pipeline layout strategy is adjusted based on the set search activity level, resulting in multiple domain layout strategies. This step is essentially a process of generating new strategies. This process may involve random or targeted changes to certain parameters of the current strategy, such as adjusting pipeline paths, changing pipeline connections, or modifying pipeline spacing. Each adjustment aims to explore different regions in the strategy space to find potentially better solutions. Search activity level here plays a role in controlling the magnitude of the adjustments, ensuring that the adjustments are neither too conservative nor too aggressive, thus achieving a balance between exploration and utilization.

[0190] In some embodiments, step S603 involves integrating multiple domain layout strategies to obtain a domain strategy set.

[0191] It should be noted that these multiple domain layout strategies obtained through adjustments are integrated to form a domain strategy set. The integration process may involve filtering, deduplication, or normalization of strategies to ensure the diversity and feasibility of the strategies in the set. This set will serve as the basis for subsequent optimization processes, providing a wealth of options for further evaluation and selection of strategies. Through these steps, the method of this application can dynamically generate a domain strategy set that matches the current strategy, providing solid support for the optimization of pipeline network layout strategies.

[0192] In some more specific embodiments, step S103 involves obtaining a set of neighborhood strategies that match the current pipeline layout strategy. This process can employ a multi-neighborhood search method. Multi-neighborhood search is a strategy designed to increase search diversity and the ability to escape local optima. Specifically, this method achieves this goal by defining various neighborhood generation methods, such as local path adjustment and local exchange.

[0193] Local path adjustment is a method for making minor modifications to the current pipeline layout strategy. For example, it can change part of the path of a pipeline or adjust the relative positions of several pipelines. This adjustment method can generate new neighboring strategies in the strategy space while maintaining connectivity with other pipelines and the feasibility of the overall layout. In this way, local areas near the current strategy can be explored to identify potential improvement opportunities.

[0194] Local swapping involves exchanging certain elements of the pipeline layout strategy. For example, the connection order of two pipelines can be swapped, or the layout positions of several pipelines can be changed. This swapping operation can introduce new variations while keeping the overall layout roughly unchanged, thereby generating different neighborhood strategies. Local swapping helps to break any potential symmetry or repetition, further expanding the search scope.

[0195] By employing a multi-neighborhood search method, combined with various neighborhood generation techniques such as local path adjustment and local swapping, the diversity of the search can be effectively increased. This method allows the optimization process to not only explore the neighborhood of the current strategy but also escape the trap of local optima through different adjustment methods. A local optimum is the optimal solution within a small region but may not be the global optimum. Multi-neighborhood search increases the probability of finding the global optimum, thereby improving the effectiveness and efficiency of the entire optimization process.

[0196] In practical applications, the multi-neighborhood search method gradually expands the search scope by continuously generating and evaluating different neighborhood strategies, thus avoiding getting trapped in local optima. This method is particularly suitable for complex optimization problems, such as nuclear power plant pipeline layout, where the solution space is vast and contains numerous local optima. This approach allows for a more comprehensive exploration of the strategy space, increasing the likelihood of finding a better, or even globally optimal, pipeline layout strategy.

[0197] In some embodiments, step S104 involves selecting a domain layout strategy from the domain strategy set as a candidate network layout strategy.

[0198] It should be noted that a domain-specific deployment strategy is selected from the set of domain strategies as a candidate pipeline deployment strategy. This step involves a certain screening mechanism, such as random selection or selection based on a certain priority, with the aim of introducing new strategies to explore possible optimization directions.

[0199] Reference Figure 7 According to some embodiments of this application, before selecting a domain layout strategy from the domain strategy set as a candidate pipeline layout strategy in step S104, the following may also be included:

[0200] Step S701: Obtain the policy prohibition table; wherein, the policy prohibition table contains multiple prohibited policies;

[0201] In step S104, selecting a domain layout strategy from the domain strategy set as a candidate pipeline layout strategy may include:

[0202] Step S702: Select a domain deployment strategy from the domain strategy set. If the domain deployment strategy is not entered into the strategy prohibition table, determine the domain deployment strategy as a candidate pipeline deployment strategy.

[0203] After selecting a domain layout strategy from the domain strategy set as a candidate pipeline layout strategy in step S104, the process may further include:

[0204] Step S703: Enter the candidate pipeline layout strategy into the strategy prohibition table.

[0205] In some embodiments of this application, a strategy exclusion table mechanism is introduced before selecting candidate pipeline layout strategies from the domain strategy set to avoid repeatedly evaluating invalid or already evaluated strategies, thereby improving the efficiency and effectiveness of the optimization process.

[0206] In some embodiments, step S701 involves obtaining a policy prohibition table; wherein the policy prohibition table contains multiple prohibition policies.

[0207] It's important to note that we obtain a policy no-selection table, which contains multiple prohibited policies. This table acts like a memory, recording policies that have been evaluated or deemed unsuitable. These prohibited policies may have been previously selected and tested, performed poorly in previous evaluations, or failed to meet certain key constraints. Maintaining such a table avoids reconsidering these policies in subsequent policy selections, thereby saving computational resources and improving search efficiency.

[0208] In some embodiments, step S702 involves selecting a domain layout strategy from the domain strategy set, and if the domain layout strategy is not entered into the strategy prohibition list, determining the domain layout strategy as a candidate pipeline layout strategy.

[0209] It's important to note that when selecting a domain placement strategy from the domain strategy set, the system checks whether that strategy has already been entered into the strategy exclusion list. If the domain placement strategy does not appear in the exclusion list, it will be identified as a candidate network placement strategy. This step ensures that each selected candidate strategy is new, unevaluated, or at least not excluded in the current optimization cycle. This mechanism helps to broaden the search scope and increase the likelihood of finding a better strategy.

[0210] In some embodiments, step S703 involves entering candidate pipeline layout strategies into a strategy disqualification table.

[0211] It should be noted that once a domain layout strategy is selected as a candidate network layout strategy and evaluated, it will be entered into the strategy exclusion list regardless of the evaluation result. This operation ensures that the strategy will not be repeatedly selected in future iterations unless the exclusion list is reset or cleared. In this way, the embodiments of this application can continuously explore new strategies, avoid getting trapped in local optima, and gradually eliminate those poorly performing strategies, thereby driving the entire optimization process toward the global optimum. In this way, the method of this application, when selecting candidate strategies, not only considers the potential value of the strategies, but also effectively manages the search process through the strategy exclusion list, avoiding unnecessary repeated evaluations and improving the efficiency and effectiveness of optimization.

[0212] Reference Figure 8According to some embodiments of this application, step S703, which involves entering candidate pipeline layout strategies into a strategy disqualification table, may include:

[0213] Step S801: Obtain the time limit requirement for the prohibited selections that match the policy prohibited selection table;

[0214] Step S802: In response to the fact that the maximum number of prohibited policies have been entered in the policy prohibition table, iterate through the duration of the prohibition of each prohibited policy in the policy prohibition table; wherein, the maximum number of prohibited policies is the maximum policy capacity of the policy prohibition table.

[0215] Step S803: If the duration of the disabling does not meet the time limit requirement for disabling, the corresponding disabling strategy is removed from the strategy disabling table, and the candidate pipeline layout strategy is entered into the strategy disabling table.

[0216] In some embodiments of this application, the process of entering candidate pipeline layout strategies into the strategy prohibition table involves consideration of prohibition timeliness requirements and management of prohibition table capacity to ensure the effectiveness and practicality of the strategy prohibition table.

[0217] In some embodiments, step S801 involves obtaining the prohibition time limit requirements that match the policy prohibition list;

[0218] It should be noted that the prohibition period requirements are obtained to match the prohibition list of strategies. The prohibition period requirements specify the maximum duration for each prohibited strategy to remain in the prohibition list. This helps to dynamically manage prohibited strategies, prevent the prohibition list from being occupied by outdated strategies, and ensure that the strategies in the list have a certain timeliness and relevance.

[0219] In some embodiments, step S802 involves iterating through the duration of disabling of each disabling strategy in the policy disabling table, in response to the fact that the maximum number of disabling strategies has been entered into the policy disabling table; wherein, the maximum number of disabling strategies is the maximum policy capacity of the policy disabling table.

[0220] It should be noted that when the number of prohibited policies in the policy prohibition table reaches the capacity limit, it is necessary to iterate through the duration of each prohibited policy's disabling. This step aims to check whether each prohibited policy in the table has exceeded its allowed disabling duration. The capacity limit is the maximum number of prohibited policies the policy prohibition table can hold. This limitation ensures that the size of the prohibition table is controllable, avoiding a decrease in management and evaluation efficiency due to an excessive number of policies.

[0221] In step S803 of some embodiments, if the duration of the disabling does not meet the disabling timeliness requirement, the corresponding disabling strategy is removed from the strategy disabling table, and the candidate pipeline layout strategy is entered into the strategy disabling table.

[0222] It should be noted that for prohibited strategies whose duration does not meet the eligibility period requirements—that is, strategies that have reached or exceeded the maximum allowed duration of prohibition—they are removed from the prohibited strategy list. This is done to free up space so that new candidate network deployment strategies can be added to the list. This process not only maintains the dynamism of the prohibited strategy list but also ensures that the strategies in the list can be re-evaluated or updated within a reasonable timeframe. Through this mechanism, the prohibited strategy list can be dynamically updated and managed while maintaining a certain size, ensuring the relevance and effectiveness of its content.

[0223] In some embodiments, step S105 involves evaluating the rationality of candidate pipeline layout strategies based on the strategy objective function and strategy constraints to obtain second strategy evaluation information.

[0224] It should be noted that a rationality assessment of the candidate pipeline layout strategy is conducted to obtain the second strategy evaluation information. This step is similar to the evaluation of the initial strategy, but its purpose is to verify whether the candidate strategy is superior to the initial strategy in some aspects and whether it is closer to the optimization goal.

[0225] In step S106 of some embodiments, in response to the first strategy evaluation information and the second strategy evaluation information satisfying the strategy update conditions, an updated pipeline layout strategy is determined between the pipeline layout strategy and the candidate pipeline layout strategy.

[0226] It should be noted that if the evaluation information of the first strategy and the evaluation information of the second strategy meet the preset strategy update conditions, such as the candidate strategy being superior to the initial strategy in key performance indicators, then an updated pipeline layout strategy will be determined between the initial strategy and the candidate strategy. This step marks the iterative optimization of the strategy, driving the entire process toward a better solution.

[0227] Reference Figure 9 According to some embodiments of this application, the first strategy evaluation information includes a first evaluation score corresponding to the strategy objective function, and the second strategy evaluation information includes a second evaluation score corresponding to the candidate pipeline layout strategy. Step S106, in response to the first strategy evaluation information and the second strategy evaluation information satisfying the strategy update condition, determines an updated pipeline layout strategy between the pipeline layout strategy and the candidate pipeline layout strategy, and may include:

[0228] Step S901: In response to the first assessment score being less than or equal to the second assessment score, calculate the score difference between the second assessment score and the first assessment score;

[0229] Step S902: Calculate the probability of accepting the strategy update for the candidate pipeline layout strategy based on the score difference and search activity.

[0230] Step S903: In response to the strategy update acceptance probability reaching the preset update acceptance probability, it is determined that the strategy update condition is met, and the candidate pipeline layout strategy is determined as the updated pipeline layout strategy.

[0231] In some embodiments of this application, step S106 involves updating the pipeline layout strategy when certain conditions are met. This process is achieved through meticulous evaluation and probability calculation to ensure that the strategy update is based on evidence and is selective.

[0232] In some embodiments, step S901 involves calculating the score difference between the second evaluation score and the first evaluation score in response to the first evaluation score being less than or equal to the second evaluation score.

[0233] It should be noted that the evaluation information of the first strategy (the evaluation score of the current pipeline layout strategy) and the evaluation information of the second strategy (the evaluation score of the candidate pipeline layout strategy) are examined. If the first evaluation score is less than or equal to the second evaluation score, it indicates that the candidate strategy may be better than the current strategy or at least not worse. In this case, the difference between the two scores is calculated, and this difference reflects the degree of improvement of the candidate strategy relative to the current strategy.

[0234] In step S902 of some embodiments, the probability of accepting a strategy update is calculated for the candidate pipeline layout strategy based on the score difference and search activity.

[0235] It should be noted that, based on the calculated score difference and the current search activity, a strategy update acceptance probability is calculated for each candidate network layout strategy. Search activity plays a moderating role here, reflecting the current level of exploration in the optimization process. Higher search activity may mean a higher probability of accepting a candidate strategy, even if its improvement is not significant; while lower search activity may result in only significantly improved candidate strategies being accepted. This acceptance probability calculation comprehensively considers both the magnitude of improvement and the current search state, ensuring the rationality and flexibility of strategy updates.

[0236] In some embodiments, step S903, in response to the strategy update acceptance probability reaching a preset update acceptance probability, determines that the strategy update condition is met, and determines the candidate pipeline layout strategy as the updated pipeline layout strategy.

[0237] It should be noted that if the calculated strategy update acceptance probability reaches or exceeds the preset update acceptance probability threshold, the strategy update condition is considered met. At this point, the candidate pipeline layout strategy will be formally determined as the updated pipeline layout strategy. This step ensures that only strategies that have undergone rigorous evaluation and probability screening are adopted, thereby maintaining the stability and effectiveness of the entire optimization process. In this way, the method of this application can make reasonable choices between the current strategy and candidate strategies, ensuring that each strategy update moves towards the optimization goal while maintaining the dynamic adaptability of the optimization process.

[0238] According to some embodiments of this application, step S106, in response to the first strategy evaluation information and the second strategy evaluation information satisfying the strategy update condition, determines an updated pipeline layout strategy between the pipeline layout strategy and the candidate pipeline layout strategies, and may include:

[0239] If the first evaluation score is higher than the second evaluation score, it is determined that the strategy update condition is met, and the candidate pipeline layout strategy is determined as the updated pipeline layout strategy.

[0240] When the first evaluation score is higher than the second evaluation score, it indicates that the candidate pipeline layout strategy outperforms the current pipeline layout strategy under the given strategy objective function. In this case, the embodiments of this application determine that the strategy update condition has been met. At this time, the candidate pipeline layout strategy will be formally adopted as the updated pipeline layout strategy. This decision logic ensures that the existing strategy will only be replaced when the candidate strategy shows better performance, thereby guaranteeing the steady progress of the entire optimization process.

[0241] The core of this mechanism lies in driving strategy updates through the comparison of evaluation scores. Evaluation scores quantify a strategy's performance under a given objective function and may incorporate multiple factors, such as total pipeline length, number of bends, number of intersections, safety, and ease of maintenance. Therefore, when a candidate strategy has a lower evaluation score, it means that it outperforms the current strategy in these key metrics and is worthy of adoption as the new current strategy for continued optimization iterations.

[0242] In this way, the method of this application can move towards a better policy in each iteration, gradually approaching the global optimum or at least a solution very close to the global optimum. This policy update mechanism based on evaluation score comparison is not only simple and effective, but also ensures the stability and directionality of the optimization process.

[0243] In some embodiments, step S107 involves returning to the execution of a reasonable evaluation of the pipeline layout strategy based on the updated pipeline layout strategy, using the strategy objective function and strategy constraints, until the preset strategy optimization conditions are met, and then determining the pipeline layout strategy as the target pipeline layout strategy.

[0244] It should be noted that, based on the updated pipeline layout strategy, a rationality evaluation based on the strategy objective function and strategy constraints is performed. This loop will continue until the preset strategy optimization conditions are met, such as reaching the maximum number of iterations or the strategy performance no longer showing significant improvement. Finally, when the optimization conditions are met, the current pipeline layout strategy will be determined as the target pipeline layout strategy, that is, it is considered to be the optimal or near-optimal solution.

[0245] Reference Figure 10 According to some embodiments of this application, step S107, based on the updated pipeline layout strategy, returns to perform a rationality evaluation of the pipeline layout strategy based on the strategy objective function and strategy constraints, until the preset strategy optimization conditions are met, and the pipeline layout strategy is determined as the target pipeline layout strategy, which may include:

[0246] Step S1001: Based on the updated pipeline layout strategy, adjust the search activity to reduce the search activity.

[0247] Step S1002: After reducing the search activity, according to the updated pipeline layout strategy, return to the execution based on the strategy objective function and strategy constraints to evaluate the rationality of the pipeline layout strategy until the preset strategy optimization conditions are met, and determine the pipeline layout strategy as the target pipeline layout strategy.

[0248] In some embodiments of this application, step S107 involves continuing a rationality evaluation after updating the pipeline layout strategy until preset strategy optimization conditions are met, thereby determining the final pipeline layout strategy. Specifically, after the pipeline layout strategy is updated, the evaluation process is returned to and re-executed to verify whether the updated strategy still meets the optimization objectives and constraints. This cyclical process continues until a specific termination condition is met, such as reaching the maximum number of iterations or the strategy performance no longer significantly improves.

[0249] In some embodiments, step S1001 involves adjusting the search activity based on the updated pipeline layout strategy to reduce the search activity.

[0250] It should be noted that, based on the updated pipeline layout strategy, the search activity is adjusted, specifically by reducing it. Search activity is a control parameter used to regulate the breadth of strategy exploration. Reducing search activity means that in subsequent optimization processes, this embodiment will focus more on local areas near the current strategy, conducting more detailed exploration and optimization. This is typically done in the later stages of the optimization process, when the strategy is close to the optimal solution. Reducing search activity refines the search to more accurately find the globally optimal or near-globally optimal solution.

[0251] In some embodiments, step S1002 involves reducing search activity and then, according to the updated pipeline layout strategy, returning to perform a rationality evaluation of the pipeline layout strategy based on the strategy objective function and strategy constraints until the preset strategy optimization conditions are met, and then determining the pipeline layout strategy as the target pipeline layout strategy.

[0252] It should be noted that after reducing search activity, a rationality evaluation based on the policy objective function and policy constraints is re-executed according to the updated pipeline layout strategy. This step ensures that the strategy still meets all optimization objectives and constraints after the search activity adjustment. Through this iterative evaluation method, the embodiments of this application can continuously verify and optimize the strategy, gradually approaching the optimal solution.

[0253] According to some embodiments of this application, in step S1002, until the preset strategy optimization conditions are met, determining the pipeline layout strategy as the target pipeline layout strategy may include:

[0254] When the search activity decreases to a preset activity threshold, or when the number of updates to the pipeline layout strategy reaches a preset number of iterations, the strategy optimization condition is determined to be met, and the pipeline layout strategy is determined as the target pipeline layout strategy.

[0255] It should be noted that the determination of whether the strategy optimization condition is met is crucial. Specifically, this embodiment of the application determines that the strategy optimization condition has been met when the search activity decreases to a preset activity threshold, or when the number of updates to the pipeline layout strategy reaches a preset number of iterations. At this point, the current pipeline layout strategy will be determined as the target pipeline layout strategy. This termination condition ensures that the optimization process neither stops prematurely nor continues indefinitely, thereby finding a satisfactory solution within reasonable time and computational resources. In this way, the method of this application can efficiently find a pipeline layout strategy that satisfies all optimization objectives and constraints, providing a scientific basis for the design and operation of nuclear power plants.

[0256] In some embodiments, step S108 involves performing nuclear power plant pipeline layout operations according to the target pipeline layout strategy.

[0257] It should be noted that, based on the target pipeline layout strategy, the actual nuclear power plant pipeline layout operation is executed. This step transforms the optimization results into practical engineering applications, completing the transformation from strategy optimization to actual operation, thereby improving the design efficiency, economy, and safety of nuclear power plants, while reducing human error and enhancing the intelligence level of engineering design.
