Description

Technical Field

[0001] This invention relates to the field of bridge construction and operation and maintenance technology, and more specifically, to a method and apparatus for dynamically adjusting carbon emissions during the construction and operation and maintenance period of railway bridges. Background Technology

[0002] In existing bridge construction and operation technologies, firstly, carbon emission assessments primarily rely on subjective expert evaluations, which are inherently uncertain and unsuitable for supporting multi-objective optimization decisions. Secondly, the identification of key influencing factors largely depends on empirical judgment, lacking a quantitative characterization of the coupling relationship between energy consumption, environment, and economic systems, thus failing to accurately assess the impact of each factor on carbon emissions. Finally, complex inherent trade-offs exist among multiple conflicting objectives such as resources, environment, and economy, and existing technologies cannot effectively coordinate these objectives. Consequently, carbon emissions throughout the entire railway bridge construction and operation process are difficult to adjust and optimize, leading to the problem of ineffective carbon emission reduction during construction and operation.

[0003] Therefore, there is an urgent need for a method and device for dynamically adjusting carbon emissions during the construction and maintenance of railway bridges, which would solve the problem of the inability to effectively reduce carbon emissions during construction and maintenance. Summary of the Invention

[0015] The optimization module is used to optimize the Pareto solution set of the green construction evaluation model based on chaotic mapping and non-dominated sorting genetic algorithm, and to calculate decision indicators on the Pareto solution set through the cloud similarity model to obtain a multi-objective decision scheme.

Furthermore, in the description of this invention, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0026] Example 1:

[0027] This embodiment provides a method for dynamically adjusting carbon emissions during the construction and maintenance period of railway bridges.

[0028] See Figure 1 The figure shows that the method includes steps S1 to S5, including:

[0029] S1: Obtain data on the bridge's resource consumption, environmental impact, and economic benefits.

[0030] S2: Construct a green construction evaluation model by taking the data on resource consumption, environmental impact and economic benefits;

[0031] To clarify the specific method for obtaining the green construction evaluation model, step S2 includes S21 to S23, specifically:

[0032] S21: The data on resource consumption, environmental impact and economic benefits are screened through preset preliminary screening constraints to obtain a preliminary evaluation index system;

[0033] In this step, the preliminary screening constraints are set based on the actual situation during the construction and operation of railway bridges, as well as industry standards and specifications. By eliminating indicator data that is difficult to obtain, highly repetitive, or not closely related to green construction goals, the preliminary evaluation indicator system is designed to comprehensively and specifically reflect the resource consumption, environmental impact, and economic benefits during the construction and operation of railway bridges.

[0034] S22: Classify the preliminary evaluation index system based on the DPSIR model, and optimize the duplicate indicators through the classified index system to obtain the optimized evaluation index.

[0035] In this step, the DPSIR model is a five-dimensional model of driving force, pressure, state, influence, and response. Based on the DPSIR model, the preliminary evaluation index system is classified. After classification, the indicators under the same dimension are analyzed to find indicators that are duplicated or highly correlated. Duplicate indicators are merged or removed, and highly correlated indicators are screened according to the importance of green construction evaluation, retaining the most representative and key indicators.

[0036] S23: Based on the optimized evaluation indicators and the preset general indicator system, a green construction evaluation model is constructed to obtain the green construction evaluation model.

[0037] In this step, the general indicator system is formulated based on widely recognized green construction evaluation standards and specifications within the industry. The optimized indicators are compared with the general indicator system; optimized data is used for existing indicators, and new indicators are incorporated into the model according to their importance. The model structure and weight allocation are optimized to reflect resource consumption, environmental impact, and economic benefits, thus constructing a scientific and systematic green construction evaluation model.

[0038] S3: Based on network hierarchy analysis, determine the weight of each indicator in the green construction evaluation model, and conduct similarity evaluation of each indicator weight through a weighted cloud model to construct a cloud similarity model;

[0039] This step determines the indicator weights through network hierarchy analysis and constructs a cloud similarity model by combining the similarity evaluation of the weighted cloud model, which is used to dynamically evaluate the construction and operation process.

[0040] To clarify the specific method for obtaining the cloud similarity model, step S3 includes S31 to S35, specifically:

[0041] S31: Obtain historical survey data;

[0042] S32: Based on network hierarchy analysis, the green construction evaluation model is constructed to obtain a network hierarchy model, which includes a target layer, a standard layer, and a scheme layer.

[0043] In this step, the green construction evaluation model, which aims to achieve multi-objective optimization of the entire process of railway bridge construction and operation, is designated as the objective layer. The three criteria dimensions of resource consumption, environmental impact, and economic benefits in the green construction evaluation model are designated as the standard layer. The construction technology path, material selection scheme, and equipment usage scheme in the green construction evaluation model constitute the scheme layer. This hierarchical construction method clearly demonstrates the hierarchical relationship between the various indicators.

[0044] S33: Analyze the correlation between each indicator in the green construction evaluation model based on the historical survey data to obtain the indicator feedback relationship;

[0045] In this step, based on the historical survey data, the mutual influence and feedback mechanism between each indicator in the green construction evaluation model are analyzed to determine the dependence and feedback relationship between each indicator and to construct the indicator feedback relationship.

[0046] S34: Based on the feedback relationship of the indicators, determine the weight of each indicator in the green construction evaluation model to obtain the indicator weight value;

[0047] To clarify the specific method for obtaining the indicator weight values, step S3 includes S341 to S345, specifically:

[0048] S341: Based on the feedback relationship of the indicators, the weight of each indicator in the green construction evaluation model is determined to obtain the initial weight of the indicators;

[0049] In this step, the importance of the indicators in the green construction evaluation model is initially assessed based on the feedback relationship between the indicators, and an initial weight is assigned to each indicator. The initial weight reflects the relative importance of the indicators without considering the influence of other factors.

[0050] S342: Based on the network hierarchy model, compare the indicators with dependent feedback relationships, determine the relative importance by combining the initial weights of the indicators, and obtain the ranking vector;

[0051] In this step, the indicators with dependent feedback relationships are compared pairwise based on the network hierarchy model, and the relative importance between the indicators is determined by combining the initial weights of the indicators.

[0052] The ranking vector of each indicator is calculated by the eigenvalue method. The ranking vector is used to accurately reflect the relative importance of each indicator in the comprehensive evaluation.

[0053] S343: Analyze the interrelationships of the indicators in the network hierarchical model to obtain an unweighted hypermatrix;

[0054] In this step, the relationships between the indicators in the network hierarchy model are analyzed to determine the direct and indirect relationships, and then an unweighted supermatrix is ​​constructed.

[0055] S344: Normalize the sorting vector, construct a weighted matrix using the normalized sorting vector, and construct a weighted supermatrix by combining the unweighted supermatrix with the weighted matrix.

[0056] In this step, the ranking vector is normalized to ensure that the sum of the weights of each indicator is 1, thus obtaining a normalized ranking vector. Then, a weighted matrix is ​​constructed using the normalized ranking vector. The unweighted hypermatrix is ​​multiplied by the weighted matrix to obtain a weighted hypermatrix. This weighted hypermatrix reflects the interaction and weight influence between the indicators.

[0057] S345: Stabilize the weighted supermatrix and calculate the index weight values.

[0058] In this step, the weighted hypermatrix undergoes stabilization processing, and its stability is ensured through iterative calculation. Finally, the weight values ​​of each indicator are calculated and used as indicator weight values, which accurately reflect the importance of each indicator in the green construction evaluation.

[0059] S35: Based on the index weight values ​​and the reverse cloud generation model, the indicators in the green construction evaluation model are comprehensively calculated and constructed to obtain the cloud similarity model.

[0060] To clarify the further acquisition method of the cloud similarity model, step S35 includes S351 to S355, specifically:

[0061] S351: Obtain the cloud model for indicator evaluation;

[0062] S352: Based on the index weight values ​​and the reverse cloud generation model, the digital features in the evaluation cloud model are constructed to obtain the index standard cloud model;

[0063] In this step, based on the indicator weight values ​​and the reverse cloud generation model, the digital features in the evaluation cloud model are adjusted and optimized to construct the indicator standard cloud model. Specifically, the indicator weight values ​​are combined with the digital features in the evaluation cloud model, and the position, width, and thickness are weighted to construct the indicator standard cloud model.

[0064] S353: Calculate and arrange the EPTCM cloud similarity between the indicator standard cloud model and the indicator evaluation cloud model to obtain a similarity matrix;

[0065] In this step, the differences between the indicator standard cloud model and the indicator evaluation cloud model in three numerical features—position, width, and thickness—are first calculated to obtain the similarity value for each feature. Then, these three similarity values ​​are combined to obtain the overall similarity between the indicator standard cloud model and the indicator evaluation cloud model. The similarity value is calculated for all indicators sequentially, and the similarity values ​​are arranged and combined by rows and columns to finally form a similarity matrix.

[0066] S354: Based on the index weight values ​​and the similarity matrix, a similarity judgment matrix is ​​constructed;

[0067] In this step, the weight value of each indicator is multiplied by its similarity value in the similarity matrix to obtain a weighted similarity value. Then, the weighted similarity values ​​of all indicators are arranged according to the structure of the original similarity matrix to form a similarity judgment matrix.

[0068] S355: Perform a comprehensive analysis and evaluation of the similarity in the similarity judgment matrix to construct a cloud similarity model.

[0069] In this step, the weighted similarity values ​​of each indicator are summarized and analyzed to determine the overall performance of each indicator in the green construction evaluation. Then, the entire green construction evaluation model is evaluated based on the overall performance to obtain a comprehensive evaluation result. Finally, a cloud similarity model is constructed based on the comprehensive evaluation result.

[0070] S4: The Pareto solution set of the green construction evaluation model is optimized and solved using the chaotic mapping and non-dominated sorting genetic algorithm. The decision index is calculated on the Pareto solution set using the cloud similarity model to obtain a multi-objective decision scheme.

[0071] In this step, the multi-objective decision-making scheme is used to provide a more accurate and reliable basis for decision-making in bridge construction and operation.

[0072] To clarify the specific methods for obtaining multi-objective decision-making solutions, step S4 includes S41 to S44, specifically:

[0073] S41: Based on the optimization of the population initialization process of the non-dominated sorting genetic algorithm using chaotic mapping, an optimized sorting genetic algorithm is obtained;

[0074] In this step, a series of chaotic sequences are generated based on the chaotic mapping function. These chaotic sequences are then mapped to the value range of the decision variables in the green construction evaluation model, thereby generating an initial population and obtaining the optimized sorting genetic algorithm. The initial population generated in this way more comprehensively covers the search space, improving the algorithm's search capability and optimization effect.

[0075] S42: The green construction evaluation model is solved by multi-objective optimization using the optimized sorting genetic algorithm to obtain the Pareto solution set;

[0076] In this step, the objective functions and constraints of the green construction evaluation model, including resource consumption, environmental impact, and economic benefits, are input into the optimized sorting genetic algorithm. An initial population is generated through chaotic mapping, and then iteratively evolves through genetic operations such as selection, crossover, and mutation. During each iteration, a non-dominated sorting mechanism is used to initially evaluate individuals in the population, selecting those that perform well across multiple objectives. Simultaneously, a crowding calculation mechanism further filters, retaining evenly distributed individuals and eliminating those with poor performance. Through this mechanism, the population is gradually guided towards the Pareto front, ultimately yielding the Pareto solution set.

[0077] S43: Based on the cloud similarity model, a decision index is calculated on the Pareto solution set through multi-criteria decision-making to obtain a compromise decision index value;

[0078] To clarify the specific method for obtaining the compromise decision indicator values, step S43 includes steps S431 to S433, specifically:

[0079] S431: Based on the cloud similarity model, normalize the similarity between the indicator evaluation cloud model and the indicator standard cloud model, and use the normalization result as the target weight coefficient.

[0080] In this step, the similarity between each indicator evaluation cloud model and the indicator standard cloud model is calculated based on the digital features of the cloud similarity model. Then, the similarity is normalized to a range between 0 and 1, and the normalized result is used as the target weight coefficient.

[0081] S432: Based on the target weight coefficient, the group and individual calculations are performed on different decision schemes in the Pareto solution set using the VIKOR multi-criteria decision model to obtain the group utility value and the individual regret value;

[0082] In this step, the ideal solution (optimal value) and the negative ideal solution (worst value) for each objective are determined based on the objective weight coefficients. Then, the weighted gaps for each decision scheme across all objectives are calculated and summed to obtain the group utility value. Furthermore, for each decision scheme, the weighted maximum gap across all objectives is calculated to obtain the individual regret value.

[0083] S433: Calculate the decision index based on the group utility value and the individual regret value to obtain the compromise decision index value.

[0084] In this step, the compromise decision index value comprehensively considers both group utility and individual regret, and is used to evaluate the overall performance of each alternative. The smaller the compromise decision index value, the better the balance between multiple objectives of the alternative, and the closer it is to the ideal optimal solution.

[0085] S44: Sort the candidate solutions in the Pareto solution set according to the compromise decision index value, and select the solution with the smallest compromise decision index value as the multi-objective decision solution.

[0086] S5: Based on the clustering algorithm, the multi-objective decision-making scheme is trained in a hierarchical manner to construct a green level identification model, and the carbon emissions during the construction and operation of railway bridges are dynamically adjusted in combination with historical subjective evaluations.

[0087] This step is used to adjust strategies in a timely manner according to the actual situation, to better adapt to the ever-changing environment and requirements, and to ensure that the construction and operation and maintenance process is always in a good green state.

[0088] To clarify the specific method for obtaining dynamic adjustments, step S5 includes S51 to S54, specifically:

[0089] S51: The multi-objective decision-making scheme is hierarchically divided based on a clustering algorithm, and multiple cluster centers are randomly generated through different levels to obtain the initial cluster centers;

[0090] In this step, the number of clusters K is pre-set based on the clustering algorithm, and the multi-objective decision scheme is classified into levels. In the feature space of the multi-objective decision scheme, K points are randomly selected as the initial cluster centers.

[0091] S52: Calculate the distance between the compromise decision index value in the multi-objective decision scheme and the initial cluster center, and assign each scheme in the multi-objective decision scheme to the nearest cluster based on the distance result to obtain the green level recognition model;

[0092] In this step, after being assigned to the nearest cluster, the average of all schemes within each cluster is calculated, and this average is used as the new cluster center. This process is repeated until the cluster centers no longer change or change only slightly, completing the cluster training. Based on the final cluster centers and the schemes within each cluster, threshold ranges for each green level are defined, and a green level recognition model is constructed.

[0093] S53: Based on the green level identification model and the preset green level warning interval, a warning model is constructed to obtain the warning model;

[0094] In this step, the green level warning range includes a good level, a moderate level, and a severe level, and the specific settings are as follows:

[0095] The warning range for a "good" rating is set to [0, 0.3].

[0096] The warning range for general levels is set to (0.3, 0.7].

[0097] The warning range for the severity level is set to (0.7, 1].

[0098] Based on the green level identification model, the compromise decision indicator values ​​are compared with the preset green level warning intervals to construct an early warning model. The specific rules are as follows:

[0099] A red warning signal is issued when the compromise decision indicator value falls within the warning range of the "serious" level; a yellow warning signal is issued when the compromise decision indicator value falls within the warning range of the "moderate" level; and a green warning signal is issued when the compromise decision indicator value falls within the warning range of the "good" level.

[0100] S54: Based on the aforementioned early warning model and historical subjective evaluation, dynamically adjust the carbon emissions during the construction and maintenance period of railway bridges.
