Description

Technical Field

[0001] This application relates to the field of nuclear power technology, and in particular to a method, apparatus, computer equipment, readable storage medium, and program product for pre-employment assessment of nuclear power plant operators. Background Technology

[0002] In nuclear power plants, the operations team is the smallest unit responsible for ensuring unit operation, with operators as the core execution unit. Currently, the industry has established a selection and authorization mechanism centered on on-the-job training. Through multi-stage training and assessment, this ensures operators possess the professional skills required for their positions, building a static qualification safety barrier. However, with increasing safety requirements, operators' condition before each shift may dynamically change due to factors such as physical fatigue, illness, and psychological stress. Failure to identify these changes in a timely manner will affect operational reliability and threaten unit safety. Therefore, pre-shift condition assessment has become a critical requirement for ensuring on-duty capabilities and improving unit safety.

[0003] Traditional methods typically use wearable devices, environmental sensors, and computer vision to monitor operators' physiological indicators and behavioral states in real time to assess their workload and stress. However, traditional methods cannot predict the operator's condition before they start work, thus losing a preventative barrier and further reducing assessment efficiency. Summary of the Invention

[0004] Therefore, it is necessary to provide a method, device, computer equipment, readable storage medium, and program product for pre-job assessment of nuclear power plant operators that can improve assessment efficiency, in response to the above-mentioned technical problems.

[0005] Firstly, this application provides a pre-employment assessment method for nuclear power plant operators, including:

[0006] Establish a questionnaire test bank and a cognitive test bank; the questionnaire test bank includes a status assessment questionnaire and a nuclear power professional test questionnaire; the cognitive test bank includes cognitive test questions.

[0007] According to the pre-employment testing plan, multi-dimensional questionnaires and multi-dimensional test questions are obtained from the questionnaire test library and the cognitive test library. Based on the multi-dimensional questionnaires and multi-dimensional test questions, pre-employment assessment test questions are generated.

[0008] The client obtains the assessment test results from the operators regarding the pre-job assessment test questions; the assessment test results include the questionnaire test results corresponding to the multi-dimensional questionnaire and the cognitive test results corresponding to the multi-dimensional test questions;

[0009] The questionnaire scores for each dimension of the questionnaire are obtained based on the questionnaire test results, and the cognitive scores for each dimension of the test questions are obtained based on the cognitive test results.

[0010] Based on the questionnaire score and cognitive score, the current test score is obtained. Based on the current test score and the corresponding personal norm score of the operator, the pre-job status of the operator is assessed.

[0011] In one embodiment, the step of obtaining multi-dimensional questionnaires and multi-dimensional test questions from a questionnaire test library and a cognitive test library according to the pre-employment testing plan includes:

[0012] Obtain the testing timeline of the pre-employment testing plan;

[0013] Candidate questionnaires and candidate test questions that match the testing timeliness are obtained from the questionnaire test library and the cognitive test library respectively using random functions;

[0014] In response to the new operation triggered by the administrator through the display interface, retrieve the new questionnaire and new test questions added by the administrator;

[0015] A multi-dimensional questionnaire is generated based on the candidate questionnaires and the newly added questionnaires, and multi-dimensional test questions are generated based on the candidate test questions and the newly added test questions.

[0016] In one embodiment, the step of obtaining questionnaire scores for each dimension of the questionnaire based on the questionnaire test results includes:

[0017] For each dimension of the questionnaire, based on the questionnaire test results corresponding to the current dimension, obtain the question scores for each questionnaire item in the current dimension.

[0018] The average score of all questionnaire items in the current dimension is taken as the questionnaire score for the current dimension.

[0019] In one embodiment, the cognitive test results include accuracy and reaction time; the steps for obtaining cognitive scores for each dimension of the test items based on the cognitive test results include:

[0020] For each dimension of the test question, a cognitive score is obtained based on the preset score of the current dimension test question, the cognitive test result corresponding to the current dimension test question, and the norm reaction time of the operators. The cognitive score is the average of the first cognitive score and the second cognitive score. The first cognitive score is the product of the accuracy corresponding to the current dimension test question and the preset score. The second cognitive score is the product of the deviation between the reaction time corresponding to the current dimension test question and the norm reaction time and the preset score.

[0021] In one embodiment, the step of assessing the pre-job status of operators based on the current test score and the individual norm score corresponding to the operator includes:

[0022] Obtain the deviation between the current test score and the individual norm score corresponding to the operator; the deviation includes the questionnaire score deviation for each dimension of the questionnaire, the cognitive score deviation for each dimension of the test questions, and the comprehensive score deviation for the current test score; the current test score is obtained by summing all questionnaire scores and all cognitive scores;

[0023] Determine the status level corresponding to the deviation value, and determine the pre-job status of the operators based on the status level; the status levels include excellent, qualified, and unqualified.

[0024] In one embodiment, the method further includes:

[0025] If any deviation value corresponds to a status level that is unqualified, the pre-job status of the operator is determined to be unqualified.

[0026] If all deviation values ​​correspond to a qualified status level, and there is a status level corresponding to any questionnaire score deviation value or any cognitive score deviation value that is excellent, and the status level corresponding to the comprehensive score deviation value is excellent, then the pre-job status of the operator is determined to be excellent.

[0027] Secondly, this application also provides a pre-job assessment device for nuclear power plant operators, comprising:

[0028] The test library creation module is used to create questionnaire test libraries and cognitive test libraries; the questionnaire test library includes status assessment questionnaires and nuclear power professional test questionnaires; the cognitive test library includes cognitive test questions;

[0029] The test question generation module is used to obtain multi-dimensional questionnaires and multi-dimensional test questions from the questionnaire test library and the cognitive test library according to the pre-employment test plan, and generate pre-employment assessment test questions based on the multi-dimensional questionnaires and multi-dimensional test questions.

[0030] The results acquisition module is used to obtain the assessment test results provided by the operators in response to the pre-job assessment test questions through the client. The assessment test results include the questionnaire test results corresponding to the multi-dimensional questionnaire and the cognitive test results corresponding to the multi-dimensional test questions.

[0031] The scoring acquisition module is used to obtain questionnaire scores for each dimension of the questionnaire based on the questionnaire test results, and to obtain cognitive scores for each dimension of the test questions based on the cognitive test results.

[0032] The status assessment module is used to obtain the current test score based on the questionnaire score and cognitive score, and to assess the pre-job status of the operators based on the current test score and the corresponding personal norm score of the operators.

[0033] Thirdly, this application also provides a computer device, including a memory and a processor, wherein the memory stores a computer program, and the processor executes the computer program to implement the method steps of any one of the first aspects.

[0034] Fourthly, this application also provides a computer-readable storage medium having a computer program stored thereon, wherein the computer program, when executed by a processor, implements the method steps of any one of the first aspects.

[0035] Fifthly, this application also provides a computer program product, including a computer program that, when executed by a processor, implements the method steps of any one of the first aspects.

[0036] The aforementioned pre-job assessment methods, devices, computer equipment, readable storage media, and program products for nuclear power plant operators establish a questionnaire test library and a cognitive test library. Based on the pre-job testing plan, they retrieve multi-dimensional questionnaires and test questions from these libraries, generate pre-job assessment test questions, and obtain the assessment results from operators' responses through a client-side application. They then obtain questionnaire scores for each dimension of the questionnaires based on the questionnaire results, cognitive scores for each dimension of the test questions based on the cognitive test results, and obtain the current test score based on both the questionnaire and cognitive scores. Finally, based on the current test score and the operator's corresponding personal norm score, they assess the operator's pre-job status. This approach enables accurate prediction of pre-job status, improves the efficiency of pre-job status assessment, and ensures that the assessment results align with the actual working scenarios in nuclear power plants, thereby enhancing the reliability of the pre-job status assessment.

[0049] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0050] The pre-job assessment method for nuclear power plant operators provided in this application embodiment can be applied to, for example... Figure 1In the application environment shown, terminal 102 communicates with server 104 via a network. A data storage system can store the data that server 104 needs to process. The data storage system can be integrated onto server 104 or placed on the cloud or other network servers. Terminal 102 is used to establish a questionnaire test library and a cognitive test library. According to the pre-employment testing plan, it retrieves multi-dimensional questionnaires and multi-dimensional test questions from these libraries. Based on these, it generates pre-employment assessment test questions. It obtains the assessment test results from the operators' feedback on the pre-employment assessment test questions through a client. Based on the questionnaire test results, it obtains questionnaire scores for each dimension of the questionnaires. Based on the cognitive test results, it obtains cognitive scores for each dimension of the test questions. Based on the questionnaire scores and cognitive scores, it obtains the current test score. Based on the current test score and the operator's corresponding personal norm score, it assesses the operator's pre-employment status. Terminal 102 can be, but is not limited to, various personal computers, laptops, smartphones, tablets, drones, low-altitude aircraft, IoT devices, and portable wearable devices. IoT devices can include smart speakers, smart TVs, smart air conditioners, smart vehicle devices, projection devices, etc. Portable wearable devices can include smartwatches, smart bracelets, and head-mounted displays. Head-mounted displays can be virtual reality (VR) devices, augmented reality (AR) devices, smart glasses, etc. Server 104 can be a standalone physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server providing cloud computing services.

[0051] In one exemplary embodiment, such as Figure 2 As shown, a pre-job assessment method for nuclear power plant operators is provided, and this method is applied to... Figure 1 Taking terminal 102 as an example, the explanation includes the following steps 202 to 210. Wherein:

[0052] S202: Establish a questionnaire test bank and a cognitive test bank; the questionnaire test bank includes a status assessment questionnaire and a nuclear power professional test questionnaire; the cognitive test bank includes cognitive test questions.

[0053] Optionally, the questionnaire test library includes a status assessment questionnaire and a nuclear power professional test questionnaire. The status assessment questionnaire covers general dimensions such as emotional state, fatigue level, and workload; the nuclear power professional test questionnaire is designed specifically for the nuclear power industry, focusing on professional scenarios such as operational isolation, work order management, inspection area optimization, and operator training, ensuring that the questionnaire accurately captures the job-related status of nuclear power operators. The cognitive test library includes cognitive test questions designed around perception, attention, memory level, and cognitive control, quantifying the cognitive performance of operators through interactive test questions.

[0054] As exemplified, Table 1 is an example of a status assessment questionnaire.

[0055] Table 1 Sample Questionnaire for Status Assessment

[0056]

[0057] Optionally, the cognitive test library includes corresponding mini-tests focusing on perception (reaction speed), attention levels, memory levels, and cognitive control. These mini-tests effectively monitor and collect data on the operator's current state. If the operator is not performing well, the accuracy and reaction time of these tests can be clearly reflected, allowing personnel status to be directly assessed through data.

[0058] For example, such as Figure 3 As shown, Figure 3 This is an example of a cognitive test sample. Figure 3 By pressing the start button, the small ball on the left will move to the right along the horizontal line at a certain random speed. When it passes through the circular area, the tester needs to click the stop button when it feels like it is about to reach the center of the circle. The final number of circles can be used as a sensory feedback.

[0059] S204: According to the pre-employment testing plan, obtain multi-dimensional questionnaires and multi-dimensional test questions from the questionnaire test library and the cognitive test library, and generate pre-employment assessment test questions based on the multi-dimensional questionnaires and multi-dimensional test questions.

[0060] Optionally, based on a pre-set pre-employment testing plan (such as daily or monthly tests), questions are selected from two types of databases to generate the final test questions. The selection methods are manual and automatic. Manual selection allows for the selection of specific dimensions of questions as needed; automatic selection uses a random function to draw questions (e.g., randomly selecting 6 emotion questions, 5 fatigue questions, 4 load questions, and 4 cognitive test questions), with monthly tests having more questions than daily tests, balancing assessment efficiency and depth. After the questionnaire database is established, a portion of the questionnaire questions can be selected manually or automatically on the server side to form a questionnaire testing plan. After publishing, users can log in and take the test on the client side.

[0061] S206: Obtain the assessment test results from operators regarding the pre-job assessment test questions through the client; the assessment test results include the questionnaire test results corresponding to the multi-dimensional questionnaire and the cognitive test results corresponding to the multi-dimensional test questions.

[0062] Optionally, after generating the pre-employment assessment test questions, the test questions are published to the client. Operators need to log in with an authorized ID, complete the questionnaire test first, and then the cognitive test. The questionnaire test results are the answer choices for each question, while the cognitive test results are accuracy and reaction time data, ensuring the integrity and traceability of the original data.

[0063] Optionally, after the test plan is finalized and published, operators log in to the client with an authorized ID, and the client will then display the corresponding questions. Testers complete the questionnaire and cognitive tests according to the instructions. For the questionnaire, each page in the client displays 4-5 questions; completing the current page advances to the next. A progress reminder is displayed at the bottom of the page, and a "Submit Questionnaire" button is located in the lower right corner. If not all questions are answered, clicking "Submit Questionnaire" will display "Incomplete Answers"; if modifications are needed, users can swipe left or right to edit their responses. Upon completion of this section, a message will appear stating "You have completed the questionnaire section." After a short break, clicking "Continue Test" will take you to the cognitive test section. Each cognitive test has instructions explaining the process. The cognitive test includes an experimental section and a formal section. The experimental section is designed to familiarize test takers with the testing process. Upon completion of all tests, a message will indicate the test is finished, and the results will be displayed on the client. Clicking "End" will exit the test.

[0064] S208: Obtain questionnaire scores for each dimension of the questionnaire based on the questionnaire test results, and obtain cognitive scores for each dimension of the test questions based on the cognitive test results.

[0065] Optionally, the test results include questionnaire test results and cognitive test results. The questionnaire test items can cover three dimensions: emotion, fatigue, and workload. The cognitive test includes four dimensions: attention, perception, control, and memory level. Through this test, questionnaire scores and cognitive test results can be obtained for different dimensions.

[0066] S210: Based on the questionnaire score and cognitive score, obtain the current test score, and assess the pre-job status of the operator based on the current test score and the corresponding personal norm score of the operator.

[0067] Optionally, as the number of tests and the sample size increase, two types of norm data will be included. One type is the norm values ​​for each dimension corresponding to the ID, including the means of multiple dimensions of the questionnaire (e.g., X1, X2, and X3 represent the mean scores of the emotional, load, and stress categories of the ID in the database, respectively) and the means of different types of cognitive tests (e.g., Y1, Y2, Y3, and Y4 represent the mean accuracy / reaction time of attention, perception, control, and memory levels of the ID in the database, respectively). In addition, there is the total test norm value of the ID for this test, calculated after each trial.

[0068] Optionally, for a specific test result of an operator, the test result for that ID is compared with the norm value of that ID, i.e., the deviation between the operator's test value and the operator's average state is compared. If the deviation is small, the state is judged as excellent; if the deviation is too large, it is judged as unqualified, etc.

[0069] The aforementioned pre-job assessment method for nuclear power plant operators establishes a questionnaire test library and a cognitive test library. Based on the pre-job testing plan, multi-dimensional questionnaires and test questions are obtained from these libraries. Pre-job assessment test questions are generated based on these questionnaires and test questions. The assessment results from operators regarding the pre-job assessment test questions are obtained through a client-side application. Questionnaire scores for each dimension of the questionnaires are obtained based on the questionnaire test results. Cognitive scores for each dimension of the test questions are obtained based on the cognitive test results. The current test score is obtained based on the questionnaire scores and cognitive scores. Based on the current test score and the operator's corresponding personal norm score, the pre-job status of the operator is assessed. This method enables accurate prediction of pre-job status, improves the efficiency of pre-job status assessment, and ensures that the assessment results align with the actual working scenarios of nuclear power plants, thus enhancing the reliability of the pre-job status assessment.

[0070] In an exemplary embodiment, the step of obtaining multi-dimensional questionnaires and multi-dimensional test questions from a questionnaire test library and a cognitive test library according to a pre-employment testing plan includes: obtaining the testing timeframe of the pre-employment testing plan; obtaining candidate questionnaires and candidate test questions that match the testing timeframe from the questionnaire test library and the cognitive test library respectively using a random function; in response to an administrator's new operation triggered by a display interface, obtaining the new questionnaires and new test questions added by the administrator; generating multi-dimensional questionnaires based on candidate questionnaires and new questionnaires, and generating multi-dimensional test questions based on candidate test questions and new test questions.

[0071] Optionally, test timeliness refers to the test duration specified in the pre-employment test plan, which directly determines the number and complexity of questionnaires and test questions. For example, a short daily test duration requires matching a small number of high-quality questions; a longer monthly test duration allows for matching more diverse and complex questions, avoiding test interruptions or insufficient information due to a mismatch between the number of questions and the timeliness. Candidate questionnaires and test questions matching the timeliness are obtained through a random function.

[0072] For example, for a questionnaire test library, if it is a daily test (short-term effect), the random function can select a small number of core dimension questionnaires according to the example logic (e.g., extracting 6 emotion questions, 5 fatigue questions, and 4 load questions); if it is a monthly test (long-term effect), the number of questions in each dimension is increased (e.g., increasing emotion questions to 8, adding occupational burnout and mental health dimension questions), generating candidate questionnaires. For a cognitive test library, in the short-term effect, 4 core cognitive tests are randomly matched (e.g., 1 each of perception, attention, control, and memory level); in the long-term effect, test types can be increased to generate candidate test questions. The random function ensures the randomness of question selection, avoiding memory bias caused by repeated test taking by operators, while "time-based matching" ensures that the number of questions is appropriate for the test duration.

[0073] Furthermore, such as Figure 4 As shown, based on automated topic selection, an administrator intervention entry point is reserved. When an administrator triggers a new operation through the display interface, they can manually add topics that fit specific scenarios. Administrators can add nuclear power professional questionnaires or targeted cognitive tests, and obtain the new questionnaires and test questions. Flexible adjustments are allowed according to actual operational needs, avoiding the limitations of automated topic selection in covering special cases. Candidate questionnaires and new questionnaires can be merged to form multi-dimensional questionnaires covering general dimensions and special scenarios; similarly, candidate test questions and new test questions can be merged to form multi-dimensional test questions that balance routine cognitive assessment and targeted cognitive training. Alternatively, it can also be as follows: Figure 4 As shown, the final questionnaire is selected from both candidate questionnaires and newly added questionnaires, and the final test questions are selected from both candidate test questions and newly added test questions. For example, administrators may be given higher privileges, such as prioritizing newly added questionnaires. This application does not restrict the specific methods used.

[0074] In this embodiment, by obtaining the test timeframe of the pre-employment test plan, candidate questionnaires and candidate test questions matching the test timeframe are obtained from the questionnaire test library and the cognitive test library respectively using a random function. In response to the new operation triggered by the administrator through the display interface, the newly added questionnaires and newly added test questions triggered by the administrator are obtained. Multi-dimensional questionnaires are generated based on the candidate questionnaires and newly added questionnaires, and multi-dimensional test questions are generated based on the candidate test questions and newly added test questions. This ensures the objectivity and flexibility of the test and improves the efficiency of pre-employment status assessment.

[0075] In an exemplary embodiment, the step of obtaining the questionnaire score of each dimension questionnaire based on the questionnaire test results includes: for each dimension questionnaire, obtaining the question score corresponding to each questionnaire question in the current dimension questionnaire based on the questionnaire test results corresponding to the current dimension questionnaire; and taking the average of the question scores corresponding to all questionnaire questions in the current dimension questionnaire as the questionnaire score corresponding to the current dimension questionnaire.

[0076] Optionally, for single-dimensional questionnaires, the corresponding question scores for each question can be extracted to convert the options into scores. For example, for each questionnaire question with 5 corresponding answers, a corresponding score can be set (2, 4, 6, 8, 10). Assuming that an emotion-related questionnaire has n questions, then F 情绪 This represents the average score of n questions. The same principle applies to fatigue and workload questionnaires. After obtaining the questionnaire results from operations personnel, each option is converted into a specific question score according to a pre-defined option-score correspondence rule. The average score of all questions within a dimension is calculated as the questionnaire score for that dimension, achieving aggregation from single-question scores to dimension scores.

[0077] In an exemplary embodiment, the cognitive test results include accuracy and reaction time; the step of obtaining cognitive scores for each dimension of the test questions based on the cognitive test results includes: for each dimension of the test questions, obtaining a cognitive score for the current dimension of the test questions based on the preset score of the current dimension of the test questions, the cognitive test results corresponding to the current dimension of the test questions, and the norm reaction time of the operators; the cognitive score is the average of a first cognitive score and a second cognitive score; the first cognitive score is the product of the accuracy corresponding to the current dimension of the test questions and the preset score; the second cognitive score is the product of the deviation between the reaction time corresponding to the current dimension of the test questions and the norm reaction time and the preset score.

[0078] Optionally, for cognitive tests, taking attention tests as an example, since each test may involve accuracy and reaction time, the cognitive dimensions of attention, perception, and memory are designed with a total score of 20 points, and perception is set at 10 points, based on the questionnaire and weights. For any individual test, the score = accuracy × F 认知 ×0.5+F 认知 ×0.5×[1-|Tn-T 常模 | / T 常模 )], where T n T represents the reaction time corresponding to the current dimension's test question. 常模 This represents the normal reaction time.

[0079] For example, suppose each test includes two types and seven dimensions: the questionnaire includes: emotion, fatigue, and workload; cognition includes: attention, perception, control, and memory level. The specific scores are shown in Table 2.

[0080] Table 2 Example of Score Calculation

[0081]

[0082] According to 7 dimensions and corresponding weights, calculate the final score to form the score of each ID. That is: F 岗前测试 =F 情绪 +F 疲劳 +F 负荷 +F 注意力 +F 感知觉 +F 控制力 +F 记忆水平 .

[0083] In an exemplary embodiment, the steps of evaluating the pre-job status of an operator based on the current test score and the personal norm score corresponding to the operator include: obtaining the deviation value between the current test score and the personal norm score corresponding to the operator; the deviation value includes the questionnaire score deviation value corresponding to each dimension questionnaire, the cognitive score deviation value corresponding to each dimension test question, and the comprehensive score deviation value corresponding to the current test score; the current test score is obtained by summing all questionnaire scores and all cognitive scores; determining the status level corresponding to the deviation value, and determining the pre-job status of the operator according to the status level; the status level includes excellent, qualified and unqualified.

[0084] Optionally, for a certain test situation of an operator, that is, comparing the test situation of this time through this ID with the norm value of this ID, Z = (X - μ) / σ, where X represents the original score of each dimension this time, μ represents the norm value of the corresponding dimension / overall score of this ID, and σ represents the standard deviation of the corresponding dimension of this ID. That is, by comparing the test value of this operator with the mean state of this operator, Z can be assigned Z1 and Z2 (Z1 < Z2). Within the range of (0, Z1), the deviation from the normal state is small, that is, it is judged as an excellent state. If it is outside Z2, it is considered that the current state deviates too much from the normal state and is judged as unqualified, and it is qualified between the two. Among them, the original score of each dimension is set considering the weight.

[0085] Exemplarily, the result judgment of each dimension is shown in Table 3.

[0086] Table 3 Example of Result Judgment of Each Dimension

[0087]

[0088] In addition, there is also the overall norm value calculated and generated after each test. Therefore, it can be understood that the norm is an array, which is a combination of means of different dimensions. In addition, there is also the mean of the collective norm in the database, not limited to the personal ID norm.

[0089] In this embodiment, by assessing the pre-job status of operators based on the current test score and the corresponding personal norm score of the operators, the pre-job status of operators can be accurately quantified, enabling precise prediction of pre-job status and improving the efficiency of pre-job status assessment.

[0090] In an exemplary embodiment, the method further includes: determining that the pre-job status of the operator is unqualified if the status level corresponding to any deviation value is unqualified; and determining that the pre-job status of the operator is excellent if the status levels corresponding to all deviation values ​​are qualified, and the status level corresponding to any questionnaire score deviation value or any cognitive score deviation value is excellent, and the status level corresponding to the comprehensive score deviation value is excellent.

[0091] For example, such as Figure 5 As shown, the final assessment is based on each dimension. If any dimension fails or the overall score fails, the test is considered unsatisfactory overall. If all dimensions pass, one or more dimensions are excellent, and the overall score is excellent, the overall performance is considered excellent.

[0092] In one exemplary embodiment, such as Figure 6 As shown, a pre-job assessment method for nuclear power plant operators is provided, which includes the following steps:

[0093] (1) Test database establishment: Establish a questionnaire test database and a cognitive test database; the questionnaire test database includes a status assessment questionnaire and a nuclear power professional test questionnaire; the cognitive test database includes cognitive test questions.

[0094] (2) Test Question Generation: Obtain the test timeframe of the pre-employment test plan; obtain candidate questionnaires and candidate test questions matching the test timeframe from the questionnaire test library and cognitive test library respectively using a random function; in response to the administrator's new operation triggered by the display interface, obtain the new questionnaires and new test questions added by the administrator; generate multi-dimensional questionnaires based on candidate questionnaires and new questionnaires, and generate multi-dimensional test questions based on candidate test questions and new test questions. Based on the multi-dimensional questionnaires and multi-dimensional test questions, generate pre-employment assessment test questions.

[0095] (3) Test results acquisition: The assessment test results of the operators in response to the pre-job assessment test questions are obtained through the client. The assessment test results include the questionnaire test results corresponding to the multi-dimensional questionnaire and the cognitive test results corresponding to the multi-dimensional test questions.

[0096] (4) Test score calculation: For each dimension questionnaire, based on the test results of the current dimension questionnaire, obtain the question score corresponding to each questionnaire item in the current dimension questionnaire; take the average of the question scores corresponding to all questionnaire items in the current dimension questionnaire as the questionnaire score corresponding to the current dimension questionnaire. For each dimension test item, obtain the cognitive score of the current dimension test item based on the preset score of the current dimension test item, the cognitive test results corresponding to the current dimension test item, and the norm reaction time of the operators; the cognitive score is the average of the first cognitive score and the second cognitive score; the first cognitive score is the product of the accuracy corresponding to the current dimension test item and the preset score; the second cognitive score is the product of the deviation between the reaction time corresponding to the current dimension test item and the norm reaction time and the preset score.

[0097] (5) Pre-employment status assessment: Based on the questionnaire scores and cognitive scores, obtain the current test score, and obtain the deviation value between the current test score and the corresponding personal norm score of the operator; the deviation value includes the questionnaire score deviation value corresponding to each dimension of the questionnaire, the cognitive score deviation value corresponding to each dimension of the test questions, and the comprehensive score deviation value corresponding to the current test score; the current test score is obtained by summing all questionnaire scores and all cognitive scores; determine the status level corresponding to the deviation value, and determine the pre-employment status of the operator based on the status level; the status level includes excellent, qualified, and unqualified. If the status level corresponding to any deviation value is unqualified, the pre-employment status of the operator is determined to be unqualified; if the status levels corresponding to all deviation values ​​are qualified, and the status level corresponding to any questionnaire score deviation value or any cognitive score deviation value is excellent, and the status level corresponding to the comprehensive score deviation value is excellent, the pre-employment status of the operator is determined to be excellent.

[0098] In other embodiments, the above method can be applied to, for example... Figure 7 The nuclear power plant operator pre-job assessment system shown is structured as follows: The equipment layer establishes the entire test network topology; the access layer handles access requests; the application layer defines the tests and displays results; the interaction layer manages and maintains the tests; the core algorithm layer processes the test data; and the data layer manages data storage. This hierarchical structure represents a simplified development topology for the test system.

[0099] Furthermore, such as Figure 8 As shown, through server-side web development, functions including ID account and permission management, test database management, test result data processing, and result presentation are established. This forms a complete end-to-end process from client to server, constructing a comprehensive pre-job assessment system for nuclear power plant operators. Specifically, it includes the following steps:

[0100] 1) Tester account management: By classifying and controlling account permissions, setting permissions for administrator accounts and tester accounts, and setting permissions for different types of ID accounts, effective personnel management can be achieved.

[0101] 2) Test library management: By maintaining the test library, you can personalize the daily and monthly test questionnaires and cognitive test questions.

[0102] 3) Test plan development: By developing a test plan, long-term test tasks can be customized without having to perform tests every time, thus improving testing efficiency.

[0103] 4) Test Results: The test results are presented in a visual way, showing the test situation in each dimension. Each test also provides a test sample for the entire database, providing the entire operation and testing team with a first-hand database and providing a basis for subsequent optimization, analysis and improvement.

[0104] Furthermore, after completing the above data analysis, the current test results can be presented on the client side, and simultaneously displayed on the client's webpage. In addition, all ID test data can be processed and presented. The presentation format is not limited to individual IDs, but also includes comparisons of various dimensions of the IDs of all team members. Formats include radar charts, histograms, comparison tables, etc.

[0105] For example, such as Figure 9 As shown, a 7-dimensional radar chart is plotted based on the norm values, forming a standard norm spectrum for an ID. Based on the test results, a test result spectrum is obtained. Figure 9 This allows us to clearly see which dimensions deviate significantly from the norm, enabling targeted adjustments in the future.

[0106] In this embodiment, by establishing a questionnaire test library and a cognitive test library, multi-dimensional questionnaires and multi-dimensional test questions are obtained from the questionnaire test library and the cognitive test library according to the pre-job testing plan. Based on the multi-dimensional questionnaires and multi-dimensional test questions, pre-job assessment test questions are generated. The assessment test results of the operators in response to the pre-job assessment test questions are obtained through the client. The questionnaire scores of each dimension of the questionnaire are obtained based on the questionnaire test results. The cognitive scores of each dimension of the test questions are obtained based on the cognitive test results. The current test score is obtained based on the questionnaire score and the cognitive score. Based on the current test score and the operator's corresponding personal norm score, the pre-job status of the operator is assessed. This can achieve accurate prediction of the pre-job status, improve the efficiency of pre-job status assessment, and at the same time ensure that the assessment results are consistent with the actual working scenario of nuclear power, thereby improving the reliability of the pre-job status assessment.

It is understood that the steps in different embodiments can be freely combined as needed, and all non-contradictory solutions formed by such combinations are within the scope of protection of this application.
