[0016] In order to enable ordinary persons in the art to better understand the technical solutions of the present disclosure, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings.

[0017] It should be noted that the terms "first", "second", etc. in the specification and claims of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present disclosure described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0018] The decision-making method, device and electronic equipment for the substation construction mode proposed in the present disclosure are described in detail using embodiments.

[0019] Figure 1 A flowchart of a method for deciding a substation construction mode provided in an embodiment of the present disclosure.

[0020] like Figure 1 As shown, the decision method for the substation construction mode proposed in this embodiment includes the following steps:

[0021] S101, receiving a selection operation from a client, and determining a candidate construction mode of a substation according to the selection operation.

[0022] For example, key parameters of the substation construction mode can be selected on the client's display interface to generate a selection operation. The server receives the client's selection operation and parses the information carried in the selection operation to obtain the key parameters in the substation construction mode and determine the candidate construction modes of the substation based on the key parameters.

[0023] It should be noted that the present disclosure does not limit the specific types of candidate construction modes for substations, and they can be selected according to actual conditions.

[0024] Optionally, candidate construction mode 1 of the substation is cast-in-place substation, candidate construction mode 2 of the substation is prefabricated substation (50% assembly rate), candidate construction mode 3 of the substation is prefabricated substation (75% assembly rate), and candidate construction mode 4 of the substation is prefabricated substation (90% assembly rate).

[0025] S102, obtaining an evaluation index set of candidate construction modes, wherein the evaluation index set includes multiple levels of evaluation indexes.

[0026] In the disclosed embodiment, after obtaining the candidate construction models, a systematic, comprehensive and scientific evaluation method can be used to conduct in-depth analysis and quantitative evaluation on multiple dimensions of substation construction, such as economy, construction and operation safety, environmental protection, and resource conservation. The evaluation principles of the substation construction model evaluation system are an important guarantee to ensure that the evaluation process is scientific, systematic, comprehensive and highly operational.

[0027] Optionally, evaluation principles usually include: (1) comprehensive principle, (2) hierarchical principle, (3) independence principle, (4) measurability principle, (5) comparability principle, and (6) principle of combining qualitative indicators with quantitative indicators.

[0028] In the disclosed embodiment, the decision objectives of the candidate construction mode can be determined and graded, that is, the decision objectives are decomposed into multiple levels, usually including the target layer (first-level indicators or top-level indicators), the criterion layer (second-level indicators) and the indicator layer (third-level indicators or final-level indicators), and the elements of each level are analyzed to ensure that the decision objectives can be fully reflected.

[0029] For example, as shown in Table 1, the candidate construction models can be determined from the economic dimension, safety dimension, environmental protection dimension and resource conservation dimension, including first-level indicators (top-level indicators), second-level indicators and third-level indicators (final-level indicators).

[0030] Table 1

[0031]

[0032] S103, for each candidate construction mode, obtain the evaluation matrix of the final indicator corresponding to the candidate construction mode, recursively evaluate the final indicator from the final indicator to the upper indicator, and for the i-th level indicator, determine the evaluation matrix of the i-th level indicator according to the evaluation matrix of the i+1-th level indicator, until the evaluation matrix of the top-level indicator is obtained.

[0033] In an embodiment of the present disclosure, in response to the final-level indicator being a qualitative indicator, questionnaire information of the final-level indicator is generated, and the questionnaire information is sent to different terminal devices, and response information of the questionnaire information sent by different terminal devices is received, and the evaluation matrix of the final-level indicator is determined based on the response information.

[0034] For example, for the qualitative indicator of personnel safety (B1-1), if 80% of the respondents in the response information evaluate personnel safety as "medium", the membership degree of personnel safety (B1-1) is 0.8.

[0035] In an embodiment of the present disclosure, in response to the final-level indicator being a quantitative indicator, the indicator value of the final-level indicator is normalized to obtain the target indicator value, the membership of the target indicator value is determined according to the membership function, the membership is normalized to obtain the target membership, and based on the target membership, the evaluation matrix of the final-level indicator is determined.

[0036] Optionally, evaluation levels can be pre-set, for example: poor, relatively poor, medium, relatively good and good, a total of 5 evaluation levels, and fuzzy evaluation is performed on each indicator to obtain the membership of each indicator at each evaluation level, and the membership of each indicator at each evaluation level is summarized to obtain the evaluation matrix of the final level indicator.

[0037] For example, the expression of the evaluation matrix R of the final index can be:

[0038]

[0039] The evaluation matrix R of the final index is an m×p matrix, where m is the number of final indexes, p is the number of evaluation levels, and the element r of the evaluation matrix R is ij It is the membership degree of the i-th final-level indicator being evaluated as the j-th evaluation level.

[0040] It should be noted that for the quantitative indicators in the candidate construction models, different quantitative indicators, such as carbon emissions and costs, have different dimensions.

[0041] Therefore, the minimum Min-maximum Max normalization method can be used to normalize the quantitative indicators, standardize the values ​​of the quantitative indicators to between [0,1], and obtain the target indicator values. Then, the trapezoidal membership function is used to determine the membership of the quantitative indicators, and then the membership is normalized to obtain the target membership. Based on the target membership, the evaluation matrix of the final indicator is obtained.

[0042] For example, the evaluation matrix of cast-in-place substation is shown in Table 2.

[0043] For example, from Table 2, we can see that the evaluation matrix of the third-level indicators corresponding to the second-level indicator B1 is:

[0044]

[0045] Table 2

[0046]

[0047] In the embodiment of the present disclosure, the weight matrix of the i+1th level indicator can be obtained, and the evaluation matrix of the i+1th level indicator can be determined based on the product between the weight matrix of the i+1th level indicator and the evaluation matrix of the i+1th level indicator.

[0048] S104, determining the evaluation scores of the candidate construction modes according to the evaluation matrix of the top indicators.

[0049] In the disclosed embodiment, the evaluation matrix of the candidate construction mode can be determined according to the product between the weight matrix of the top-level indicators and the evaluation matrix of the top-level indicators, and the evaluation score of the candidate construction mode can be determined according to the product between the evaluation matrix and the preset parameter column vector matrix.

[0050] It should be noted that by presetting the evaluation level, for example, there are five evaluation levels: poor, relatively poor, medium, relatively good and good, and each evaluation level can be assigned a value. For example, poor, relatively poor, medium, relatively good and good correspond to 20 points, 40 points, 60 points, 80 points and 100 points respectively, that is, the parameter column vector corresponding to the evaluation level is C T =(c1, c2, c3, ..., c p ) T =(20, 40, 60, 80, 100) T .

[0051] In the disclosed embodiment, after obtaining the evaluation matrix of the candidate construction mode, the product between the evaluation matrix of the candidate construction mode and the preset parameter column vector matrix can be obtained, and the product is used as the evaluation score of the candidate construction mode.

[0052] S105: Determine a target construction mode of the substation from candidate construction modes according to the evaluation scores, and send the target construction mode of the substation to the client.

[0053] In the disclosed embodiment, after the evaluation scores are obtained, the evaluation scores may be sorted, and the candidate construction mode with the largest score may be selected from the candidate construction modes as the target construction mode.

[0054] For example, when the evaluation score of the candidate construction mode 1 of the substation (cast-in-place substation) is S1, the evaluation score of the candidate construction mode 2 of the substation (prefabricated substation with a 50% assembly rate) is S2, the evaluation score of the candidate construction mode 3 of the substation (prefabricated substation with a 75% assembly rate) is S3, and the evaluation score of the candidate construction mode 4 of the substation (prefabricated substation with a 90% assembly rate) is S4, if S3>S4>S2>S1, in this case, the evaluation score of the candidate construction mode 3 of the substation is the largest, then the candidate construction mode 3 of the substation, i.e. the prefabricated substation with a 75% assembly rate, is used as the target construction mode.

[0055] In summary, the decision-making method for the substation construction mode provided by the embodiment of the present disclosure receives the selection operation of the client, and determines the candidate construction mode of the substation according to the selection operation, and obtains the evaluation index set of the candidate construction mode, wherein the evaluation index set includes multi-level evaluation indicators, and for each candidate construction mode, obtains the evaluation matrix of the final indicator corresponding to the candidate construction mode, and recursively evaluates the superior indicator from the final indicator, and for the i-th level indicator, determines the evaluation matrix of the i-th level indicator according to the evaluation matrix of the i+1-th level indicator, until the evaluation matrix of the top-level indicator is obtained, and determines the evaluation score of the candidate construction mode according to the evaluation matrix of the top-level indicator, and determines the target construction mode of the substation from the candidate construction mode according to the evaluation score, and sends the target construction mode of the substation to the client, thereby, the present disclosure obtains the evaluation score of the candidate construction mode, and according to the evaluation score, can more scientifically decide the optimal target construction mode from the candidate construction mode, thereby improving the accuracy and reliability of the decision-making of the substation construction mode, and improving the decision-making efficiency of the substation construction mode, and laying a solid foundation for subsequently improving the comprehensive construction quality of the substation construction.

[0056] Figure 2 FIG. 1 is a flow chart of the decision-making method for the substation construction mode proposed in this embodiment, as shown in FIG. Figure 2 As shown, the method comprises the following steps:

[0057] S201, receiving a selection operation from a client, and determining a candidate construction mode of a substation according to the selection operation.

[0058] S202, obtaining an evaluation index set of candidate construction modes, wherein the evaluation index set includes multiple levels of evaluation indexes.

[0059] S203, for each candidate construction mode, obtain the evaluation matrix of the final indicator corresponding to the candidate construction mode, recursively evaluate the final indicator from the final indicator to the higher-level indicator, and for the i-th level indicator, determine the evaluation matrix of the i-th level indicator according to the evaluation matrix of the i+1-th level indicator, until the evaluation matrix of the top-level indicator is obtained.

[0060] In the embodiment of the present disclosure, the weight matrix of the i+1th level indicator can be obtained, and the evaluation matrix of the i+1th level indicator can be determined based on the product between the weight matrix of the i+1th level indicator and the evaluation matrix of the i+1th level indicator.

[0061] It should be noted that the present disclosure does not limit the specific method for obtaining the weight matrix, which can be selected according to actual conditions.

[0062] Optionally, a weight matrix may be obtained by using an analytic hierarchy process (AHP).

[0063] For example, scoring questionnaire information for indicators at different levels can be generated, and the scoring questionnaire information can be sent to different terminal devices associated with experts, and scoring information of the scoring questionnaire information sent by different terminal devices can be received. According to the scoring information, the judgment matrix corresponding to the indicator can be determined, wherein the scoring information is the relative importance of indicators at different levels after pairwise comparison.

[0064] For example, the 1-9 scale method can be used for scoring. According to the scoring information, the judgment matrix corresponding to the indicator is determined, as shown in Table 3. ij It can be understood as the relative importance of indicator i relative to indicator j.

[0065] Table 3

[0066]

[0067] In the embodiment of the present disclosure, after obtaining the judgment matrix, the geometric mean of each row in the judgment matrix is ​​calculated. i=1,2,…,n, n is the order of the judgment matrix, a ij To determine the value of the element in the i-th row and j-th column of the matrix, sum the rows to get the initial weight matrix W = (W1, W2, W3, ..., W n ) T Since the geometric mean may not satisfy the weight and 1 condition, it is normalized. i=1,2,…,n, get the weight matrix of the index, calculate the maximum eigenvalue of the judgment matrix, Among them, B is the judgment matrix, i is the i-th index, through the consistency index (Consistency Index, referred to as CI), that is, The random consistency ratio (RandomIndex, RI for short) is introduced. When the consistency ratio value (Consistency Ratio, CR for short) obtained by dividing CI and RI is less than 0.1, it is judged that the evaluation matrix passes the consistency test. In response to the judgment that the matrix passes the consistency test, the weight matrix is ​​used as the final weight matrix.

[0068] For example, as shown in Table 4, the weight matrix of the first-level indicators is (0.25, 0.25, 0.25, 0.25), the weight matrix corresponding to the second-level indicators (B1, B2 and B3) is (0.6667, 0.2222, 0.1111), and the weight matrix corresponding to the third-level indicators (B1-1-B1-5) is (0.2727, 0.0909, 0.0909, 0.2727, 0.2727)

[0069] Table 4

[0070]

[0071] For example, for the secondary indicator B1, the weight matrix w corresponding to the third-level indicator (B1-1-B1-5) corresponding to the secondary indicator B1 is (0.2727, 0.0909, 0.0909, 0.2727, 0.2727) and the evaluation matrix R of the third-level indicator is The evaluation matrix of the secondary indicator B1 is: w×R=(0, 0, 0.7618, 0.1846, 0.0536). Repeat the above steps to obtain the evaluation matrix of the top-level indicator.

[0072] S204, determining the evaluation matrix of the candidate construction mode according to the product of the weight matrix of the top-level indicator and the evaluation matrix of the top-level indicator.

[0073] S205, determining the evaluation score of the candidate construction mode according to the product between the evaluation matrix of the candidate construction mode and the preset parameter column vector matrix.

[0074] In the disclosed embodiment, a scoring diagram of the candidate construction mode in the indicator dimension can be generated according to the product between the evaluation matrix and the preset parameter column vector matrix, and the click operation on the scoring diagram can be monitored. In response to the click operation, the relevant information can be displayed on the scoring diagram.

[0075] S206, selecting a candidate construction mode with the largest score from the candidate construction modes according to the evaluation scores as the target construction mode.

[0076] In summary, the decision-making method for the substation construction mode provided by the embodiment of the present disclosure receives the selection operation of the client, and determines the candidate construction mode of the substation according to the selection operation, and obtains the evaluation index set of the candidate construction mode, wherein the evaluation index set includes multi-level evaluation indexes, and for each candidate construction mode, obtains the evaluation matrix of the final index corresponding to the candidate construction mode, and recursively evaluates the superior index from the final index, and for the i-th index, determines the evaluation matrix of the i-th index according to the evaluation matrix of the i+1-th index, until the evaluation matrix of the top-level index is obtained, and the weight matrix of the top-level index and the evaluation matrix of the top-level index are calculated according to the weight matrix of the top-level index. The target construction mode is determined by multiplication of the candidate construction mode and the preset parameter column vector matrix, and the evaluation matrix of the candidate construction mode is determined. The evaluation score of the candidate construction mode is determined according to the product of the evaluation matrix of the candidate construction mode and the preset parameter column vector matrix. According to the evaluation score, the candidate construction mode with the largest score is selected from the candidate construction modes as the target construction mode. Therefore, the present invention can determine the target construction mode more scientifically and flexibly by selecting the candidate construction mode with the largest score from the candidate construction modes as the target construction mode, thereby improving the accuracy and reliability of the decision-making of the substation construction mode, improving the decision-making efficiency of the substation construction mode, and laying a solid foundation for subsequently improving the comprehensive construction quality of the substation construction.
