Description

Technical Field

[0001] This invention relates to the field of nuclear power plant overhaul technology, and in particular to a method, system, storage medium and equipment for assessing and calculating overhaul man-hours in nuclear power plants. Background Technology

[0002] Currently, nuclear power plants do not conduct independent assessments of maintenance work hours during major overhauls. Instead, service fees are settled directly based on the price stipulated in the general contract, meaning the contract price is determined through discussion between both parties based on the workload assessment at the time of contract signing (annual overhauls use a base price, and ten-year overhauls use a price multiplied by 1.5). However, this method is rather crude and fails to reflect the actual workload of overhauls. It lacks reference value for workload assessment, human resource data judgment, and overhaul cost control. Therefore, a scientific calculation and assessment method is needed for work hour accounting to ensure that the settlement of service costs for overhaul personnel reflects actual implementation. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a method, system, storage medium and equipment for assessing and calculating overhaul time in nuclear power plants.

[0004] The technical solution adopted by this invention to solve its technical problem is: a method for assessing and calculating overhaul man-hours in nuclear power plants, which includes the following steps: S1.

Based on the pre-stored standard working hours list for major overhaul work, match the working hours of each work order to obtain the execution working hours of all work orders, and then obtain the total working hours of each executing unit. S3. Calculate the total service settlement amount for this round of overhaul based on the unit price of labor and the total working hours of each implementing unit as stipulated in the contract.

[0005] Furthermore, in the nuclear power plant overhaul man-hour assessment and settlement method described in this invention, the total man-hours of each implementing unit include the total execution man-hours, management man-hours, and auxiliary man-hours of each implementing unit. Step S2 includes: Based on the pre-stored standard working hours list for major overhaul work, the working hours of each work order are matched to obtain the execution working hours of all work orders, and then summed separately according to the executing unit to obtain the total execution working hours of each executing unit; The total working hours of each implementing unit are obtained based on the total execution working hours, management working hours, and auxiliary working hours of each implementing unit; and the total working hours of this overhaul are the sum of the total working hours of each implementing unit.

[0006] Furthermore, in the nuclear power plant overhaul time assessment and settlement method of the present invention, in step S2, the management time is obtained by multiplying the total execution time of the executing unit by a first preset ratio coefficient, and the auxiliary time is obtained by multiplying the total execution time of the executing unit by a second preset ratio coefficient.

[0007] Furthermore, in the nuclear power plant overhaul time assessment and settlement method described in this invention, the first preset proportional coefficient is greater than the second preset proportional coefficient.

[0008] Furthermore, in the nuclear power plant overhaul time assessment and settlement method described in this invention, the first preset ratio coefficient is 10%, and the second preset ratio coefficient is 2%.

[0009] In addition, the present invention also provides a nuclear power plant overhaul man-hour assessment and settlement system, comprising: The acquisition module is used to obtain a list of all actually executed work orders for this round of overhaul through the work order management system; each work order is marked with a corresponding execution unit. The time statistics module is used to match the time of each work order with the pre-stored standard time list for major repair work, obtain the execution time of all work orders, and obtain the total time of each execution unit accordingly. The settlement module is used to calculate the total service settlement amount for this round of overhaul based on the labor unit price and total working hours of each execution unit as stipulated in the contract.

[0010] Furthermore, in the nuclear power plant overhaul man-hour assessment and settlement system described in this invention, the total man-hours of each executing unit include the total execution man-hours, management man-hours, and auxiliary man-hours of each executing unit; the man-hour statistics module is used for: Based on the pre-stored standard working hours list for major overhaul work, the working hours of each work order are matched to obtain the execution working hours of all work orders, and then summed separately according to the executing unit to obtain the total execution working hours of each executing unit; The total working hours of each implementing unit are obtained based on the total execution working hours, management working hours, and auxiliary working hours of each implementing unit; and the total working hours of this overhaul are the sum of the total working hours of each implementing unit.

[0011] Furthermore, in the nuclear power plant overhaul time assessment and settlement system described in this invention, the management time is obtained by multiplying the total execution time of the executing unit by a first preset ratio coefficient, and the auxiliary time is obtained by multiplying the total execution time of the executing unit by a second preset ratio coefficient.

[0016] To provide a clearer understanding of the technical features, objectives, and effects of the present invention, specific embodiments of the invention are now described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise explicitly specified and limited, terms such as "installation," "connection," "linking," "fixing," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or a connection within two elements or an interaction between two elements. When an element is referred to as being "on" or "below" another element, the element can be located "directly" or "indirectly" on the other element, or there may be one or more intermediary elements. The terms "first," "second," and "third," etc., are used only for the convenience of describing the technical solution and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first," "second," "third," etc., may explicitly or implicitly include one or more of that feature. Those skilled in the art can understand the specific meaning of the above terms in the present invention according to the specific circumstances.

[0017] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of the invention. However, those skilled in the art will understand that the invention can be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods are omitted so as not to obscure the description of the invention with unnecessary detail.

[0018] In a preferred embodiment, reference Figure 1 The nuclear power plant overhaul man-hour assessment and settlement method in this embodiment includes the following steps: S1. Obtain a list of all actually executed work orders for this round of overhaul through the work order management system. Each work order is marked with a corresponding executing unit. This means that each work order has only one executing unit. In other words, the content of each obtained work order will specify the executing unit. When calculating and settling costs later, the executing unit in the work order can be directly read, and then the corresponding unit's labor unit price can be found from the pre-stored contracts.

[0019] S2. Based on the pre-stored standard working hours list for major overhaul work, match the working hours of each work order to obtain the execution working hours of all work orders, and then obtain the total working hours of each executing unit.

[0020] It is understood that the total working hours of each executing unit include the total execution working hours, management working hours, and auxiliary working hours of each executing unit. In some embodiments, the step of matching the working hours of each work order with the pre-stored standard working hour list for overhaul work to obtain the execution working hours of all work orders, and then obtaining the total working hours of each executing unit accordingly, includes: matching the working hours of each work order with the pre-stored standard working hour list for overhaul work to obtain the execution working hours of all work orders, and summing them separately for each executing unit to obtain the total execution working hours of each executing unit. The total working hours of each executing unit are obtained based on the total execution working hours, management working hours, and auxiliary working hours of each executing unit. Furthermore, the total working hours of this overhaul are the sum of the total working hours of all executing units.

[0021] In some embodiments, management hours can be obtained by multiplying the total execution hours of the executing unit by a first preset ratio coefficient, and auxiliary hours can be obtained by multiplying the total execution hours of the executing unit by a second preset ratio coefficient. The first preset ratio coefficient is greater than the second preset ratio coefficient. The first and second preset ratio coefficients can be preset and stored in memory.

[0022] S3. Calculate the total service settlement amount for this round of overhaul based on the unit price of labor and the total working hours of each implementing unit as stipulated in the contract.

[0023] In a specific implementation scenario, the first preset ratio coefficient is 10%, and the second preset ratio coefficient is 2%. The actual number of work orders executed during the overhaul is used as the data basis for time assessment and settlement. Specifically, it is divided into the following five steps: (1) Export all the actual work orders executed in this round of overhaul through the work order management system (SAP). Considering that the business scope of each execution unit is different and the labor unit price is different, each work order is marked with the corresponding execution unit. (2) Refer to the overhaul work standard time list, match the time of each work order to obtain the execution time of all work orders. Sum them separately according to the execution unit to obtain the total time of each execution unit G1 / G2 / G3……Gn. (3) In combination with the actual situation, the complete time of each work order should also consider the work order preparation, start-up conditions preparation, work completion and other factors. Therefore, it is necessary to add 10% management time and 2% auxiliary time. (4) Thus, the total working hours for this overhaul are the sum of the total working hours of each executing unit, management working hours, and auxiliary working hours, i.e.: G = (G1 + G2 + G3 + ... + Gn) × (1 + 10% + 2%). (5) Based on the unit price of labor in the contract, multiply each unit's total working hours to obtain the total service settlement amount for this overhaul, i.e.: J = (G1·J1 + G2·J2 + G3·J3 + ... + Gn·Jn) × (1 + 10% + 2%). It is understandable that the working hours of each work order can be matched with the standard working hours in the program, or the actual working hours can be filled in manually item by item, which is more accurate, but the latter involves a larger workload.

[0024] It is understandable that the execution of a task includes not only actual maintenance work, but also tasks such as safety management, quality management, on-site monitoring, and auxiliary coordination, all of which require manpower and incurred costs. Therefore, to make the actual overhaul man-hour calculation more accurate, this method considers management man-hours and auxiliary man-hours. In this embodiment, the two preferred ratios of 10% and 2% are values ​​that best match the actual situation after long-term data accumulation and were determined through joint discussions among various professionals.

[0025] Compared to the traditional practice of settling nuclear power plant overhaul service fees by assessing the workload at the time of contract signing and settling fees directly according to the contract (i.e., not based on actual workload), this solution calculates the workload based on the actual man-hours consumed during the overhaul. This enables accurate and efficient assessment of overhaul man-hours and settlement of man-hour fees, making the settlement of nuclear power plant overhaul man-hour fees more scientific. It achieves the purpose of annual workload calculation and comparison, and also provides an important reference for the correction of subsequent general contract amounts.

[0026] In another preferred embodiment, reference Figure 2 The nuclear power plant overhaul man-hour assessment and settlement system in this embodiment includes: The acquisition module is used to retrieve a list of all actually executed work orders for this round of overhaul through the work order management system. Each work order is marked with its corresponding executing unit.

[0027] The work hour statistics module is used to match the work hours of each work order with the pre-stored standard work hour list for major overhaul work, obtain the execution work hours of all work orders, and obtain the total work hours of each executing unit accordingly.

[0028] The settlement module is used to calculate the total service settlement amount for this round of overhaul based on the labor unit price and total working hours of each execution unit as stipulated in the contract.

[0029] In some embodiments, the total working hours for each execution unit include the total execution working hours, management working hours, and auxiliary working hours for each execution unit. The working hours statistics module is used to: match the working hours of each work order according to the pre-stored standard working hours list for overhaul work, obtain the execution working hours of all work orders, and sum them separately for each execution unit to obtain the total execution working hours for each execution unit. The total working hours of each execution unit are obtained based on the total execution working hours, management working hours, and auxiliary working hours of each execution unit. Furthermore, the total working hours for this overhaul are the sum of the total working hours of all execution units.

[0030] In some embodiments, management hours are obtained by multiplying the total execution hours of the executing unit by a first preset ratio coefficient, and auxiliary hours are obtained by multiplying the total execution hours of the executing unit by a second preset ratio coefficient.

[0031] This embodiment calculates the workload based on the actual man-hours consumed during the overhaul, enabling accurate and efficient assessment of overhaul man-hours and settlement of man-hour costs. This makes the settlement of man-hour costs for nuclear power overhauls more scientific, achieving the purpose of annual workload calculation and comparison. At the same time, it provides an important reference for the correction of subsequent general contract amounts.

This embodiment calculates workload based on the actual man-hours consumed during the overhaul, enabling accurate and efficient assessment of overhaul man-hours and settlement of man-hour costs.

This embodiment calculates the workload based on the actual man-hours consumed during the overhaul, enabling accurate and efficient assessment of overhaul man-hours and settlement of man-hour costs.
