[0052] Figure 1 This is a step diagram of the welder skill assessment test arrangement method provided in this embodiment. Figure 1 This embodiment provides a method for arranging a welder skill assessment examination. Through the method, the welder skill assessment examination can be intelligently arranged. Figure 2 The flowchart of the welder skill test arrangement provided in this embodiment is shown. Please refer to Figure 1 and Figure 2 The method for arranging a welder skill test provided in this embodiment includes the following steps:

[0053] S01: Get multiple exam commissions.

[0054] When a welder skill assessment test is required, each entrusting unit can initiate an examination entrustment, which includes the examination items and the candidate information corresponding to the examination items.

[0055] Figure 3 The interface diagram of multiple examination commissions received is shown, specifically, Figure 3 As shown, each entrusting unit can initiate multiple test entrustments, each test entrustment has a corresponding entrustment number, and each test entrustment can include multiple test items. It can be understood that in some other embodiments, the test entrustment initiated by each entrusting unit can also be set to one, and the one test entrustment includes multiple test items that the entrusting unit needs to take the test and the candidate information corresponding to each test item, or the test entrustment initiated by each test unit can also be set to multiple, and each test entrustment includes one test item and the candidate information corresponding to the test item. The test items in the test entrustment initiated by the entrusting unit are the test items that the entrusting unit expects to take the test.

[0056] Furthermore, before executing step S01, a step of issuing an examination plan may be included, and each entrusting unit may initiate an examination entrustment according to the examination plan after receiving the examination plan. The examination plan may include information such as the examination time period and examination location.

[0057] Optionally, in order to ensure the accuracy of information when arranging the examination, after obtaining multiple examination entrustments, the welder skill examination arranging method may also include a step of reviewing the examination entrustment. If the review is passed, the examination entrustment can be used for subsequent examination arrangement processes. If the review fails, it will be returned to the entrusting unit.

[0058] Since there are often multiple entrusting units initiating the examination entrustment when conducting the welder skill test, multiple examination entrustments are obtained, and the examination items contained in each examination entrustment partially overlap, that is, the examination items that each entrusting unit expects to take the examination may be partially the same and partially different. Therefore, after obtaining multiple examination entrustments, it is necessary to sort out the information contained in the multiple examination entrustments in order to carry out the subsequent examination arrangement process. Specifically, the sorting needs to merge the candidate information under the same examination item contained in each examination entrustment, and finally obtain the examination item types contained in all examination entrustments and the total number of candidates and candidate information contained in the examination item type.

[0059] S02: Obtain weighted scores for the test items according to the test item information and the total number of examinees corresponding to the test items, and preliminarily sort the test items according to the weighted scores for the test items.

[0060] The test item information includes the duration of the test item. The weighted score of the test item can be calculated according to the following formula:

[0061] P i =αT i +βN i

[0062] Among them, P i is the weighted score of test item i; T i is the duration of test item i; α is the weight coefficient of duration; N i is the total number of examinees for test item i; β is the weight coefficient of the total number of examinees.

[0063] Specifically, the specific values ​​of the weight coefficient α of the duration and the weight coefficient β of the total number of candidates can be set according to actual needs. For example, if the examination duration is more important for the examination item, α can be set to be greater than β; if the total number of candidates is more important for the examination item, α can be set to be less than β.

[0064] After calculating the weighted scores of the test items, the multiple test items can be preliminarily sorted in descending order according to the weighted scores of the test items. The sequence number of test item i after the preliminary sorting is j.

[0065] S03: Obtain the test item arrangement date based on the test center information and preliminary ranking.

[0066] The examination room information includes the examination time and the number of available seats. Using the dynamic programming algorithm, the formula for calculating the examination project scheduling date max_days based on the examination time and the number of available seats is as follows:

[0067]

[0068] Where n is the number of test items; j is the sequence number of test item i after preliminary sorting; T j N is the test duration of the test item with serial number j; j is the total number of examinees for the test item with serial number j; T day W is the daily examination time; day is the number of seats available per day.

[0069] S04: Obtain examination seat arrangement based on candidate information and examination items.

[0070] After determining the test date corresponding to the test item, the seats of the candidates in the test item can be arranged. Specifically, the steps of obtaining the test seat arrangement according to the candidate information and the test item include:

[0071] Construct a graph model of candidates and test items. The nodes of the graph model include candidates and test items. Specifically, each candidate is a node, and each test item is also a node. If a candidate takes a test item, a set of edges is established between the candidate node and the corresponding test item node. Furthermore, each edge can be assigned a weight to indicate the time consumed by the candidate in taking the test.

[0072] The shortest path algorithm is used to calculate the path for candidates to switch between multiple test seats, so that the same candidate can take multiple test items in the same test seat. Specifically, the shortest path algorithm is used to calculate the shortest path for candidates to switch test seats between multiple test items, minimizing the candidate's movement time during the test; by analyzing the relationship between the candidate and his multiple test items in the graph model, the test seat switching order of each candidate is optimized. The goal is to enable candidates to complete multiple tests in the same test seat and reduce switching back and forth; according to the candidate's test arrangement time window, the test seat is optimized again to ensure that the utilization rate of the same test seat is maximized, thereby determining the final test seat arrangement.

[0073] After completing the arrangement of the examination items and the seats of the examinees, the method for arranging the welder skill assessment examination may further include step S05 of arranging the invigilators. Specifically, step S05 includes:

[0074] S51: Establish the invigilator requirement for each examination seat based on the number of examination items for each examination seat.

[0075] Specifically, if the number of examination items conducted at each examination seat is N, the number of invigilators required for the examination seat is N.

[0076] S52: Allocate invigilators according to the number of invigilators required for each examination seat.

[0077] The constraint solver is used to assign invigilators, determine the number of invigilators, and ensure that the number of examination seats covered by each invigilator is within the preset range. The preset range can be set according to needs, for example, each invigilator is set to invigilate at most two or three examination seats.

[0078] The coordinate position of each examination seat is obtained, and the examination seat for each invigilator to invigilate is allocated using the K-means clustering algorithm. Specifically, K cluster centers are first initialized, where K is the number of invigilators; the cluster centers are iteratively adjusted, and the examination seat closest to each cluster center is allocated to the cluster center. The cluster centers can be updated at the same time until the division of examination seats is stable; each cluster center is allocated to an invigilator. In this way, the allocation of invigilators is achieved.

[0079] Figure 4 This is a structural block diagram of the welder skill assessment test arrangement system 100 provided in this embodiment. Figure 4 This embodiment also provides a welder skill assessment test arrangement system 100, through which the welder skill assessment test arrangement method can be executed. The welder skill assessment test arrangement system 100 includes an information management module 111, a test item arrangement module 112 and a test seat management module 113.

[0080] Information management module 111, information management module 111 is used to obtain multiple examination entrustments. Examination entrustments include examination items and examinee information corresponding to the examination items. That is, the information management module 111 can be used to execute step S01 in the welder skill assessment examination arrangement method.

[0081] The examination item arrangement module 112 is used to obtain the weighted scores of the examination items according to the examination item information and the total number of examinees corresponding to the examination items, and to preliminarily sort the examination items according to the weighted scores of the examination items; the examination item arrangement module 112 is also used to obtain the examination item arrangement date according to the examination room information and the preliminary sorting. Among them, the examination room information includes the examination time and the number of available seats. That is, the examination item arrangement module 112 can be used to execute steps S02 and S03 in the welder skill assessment examination arrangement method.

[0082] The examination seat management module 113 is used to obtain the examination seat arrangement according to the examinee information and the examination items. That is, the examination seat management module 113 can be used to execute step S04 in the welder skill assessment examination arrangement method.

[0083] Furthermore, the welder skill assessment test arrangement system 100 further includes an invigilation allocation module 114, which is used to establish the number of invigilators required for each test seat according to the number of test items for each test seat, and to allocate the invigilators according to the number of invigilators required for each test seat. Specifically, the invigilation allocation module 114 can be used to execute step S05 in the welder skill assessment test arrangement method.

[0084] Furthermore, the welder skill assessment test arrangement system 100 also includes a conflict management module 115, which is used to impose constraints on the test item arrangement module 112 and the test seat management module 113 to avoid conflicts between the test item arrangement and the test seat arrangement. Further, since the welder skill assessment test arrangement system 100 also includes an invigilation allocation module 114, the conflict management module 115 can also be configured to also impose constraints on the invigilation allocation module 114. Specifically, the conflict management module 115 has a conflict strategy, which can include detecting and resolving conflicts in the arrangement of examination rooms, sessions, and invigilators, and a conflict detection algorithm can be used. The algorithm steps include: constructing a set of constraints for each examination arrangement, and the constraints include time conflicts, examination seat conflicts, and invigilator conflicts. Then use the SAT solver to solve these constraints, and convert each constraint in the examination arrangement (time, examination room, invigilator, etc.) into a Boolean variable and a logical expression. And define the constraints:

[0085] ① One examination seat can only be supervised by one invigilator at a time period;

[0086] ② Each examination seat can only accommodate one candidate in a specific time period;

[0087] ③Each examination seat can only be arranged for one examination item during a specific time period.

[0088] The SAT solver searches for the optimal solution that satisfies all constraints by traversing the possible combinations of values ​​of the variables.

[0089] Finally, the conflict check results are optimized, with priority given to eliminating serious conflicts, such as overlapping of multiple exams in the same period.

[0090] In this embodiment, in order to ensure the smooth progress of the welder skill assessment test, the parameters of the welding process can also be monitored in real time to ensure the smooth progress of the test. Accordingly, it is also necessary to set up an equipment monitoring module 116, which has an equipment monitoring strategy. The equipment monitoring module 116 can adopt the solution provided in the invention patent with application number: 201821991722.8. Specifically, the calculation method steps of the equipment monitoring strategy include:

[0091] (1) According to the examination arrangement of each examination seat, relevant information, including candidate information and welding process parameters, is pushed to the monitoring device of the examination seat.

[0092] (2) After receiving the parameters, the welding machine monitors key information such as temperature, speed, and current during the welding process in real time.

[0093] (3) Use a feedback control system to judge the compliance of the welding process by comparing the deviation between the actual welding parameters and the standard parameters.

[0094] The welder skill assessment test arrangement method and system provided by the embodiment of the present invention can significantly improve the efficiency of the welder skill assessment test arrangement. In addition, through the graph model analysis between the test items and the examinees, the examinees can be accurately arranged to complete all the test items within the minimum number of moves. This method not only reduces the physical exertion of the examinees, but also ensures the fairness of the test, and avoids the dissatisfaction of the examinees caused by unfair distance or time. The linear programming and constraint solver are used to optimize the allocation of invigilators and test seats, so that each resource is fully and reasonably utilized. By fine-tuning the test arrangement, the idleness and repeated configuration of resources are reduced, and the efficiency of resource use is improved. The conflict management module effectively solves the problems of time conflict, test seat conflict and invigilator conflict that may occur in the test arrangement through the SAT solver. This strategy can dynamically adjust and optimize the test arrangement, ensure that all test activities are carried out smoothly under the constraints of different resources, and greatly reduce the delay and cancellation of the test caused by the conflict.

[0095] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technology in the field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
