[0038] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0039] It should be noted that the following detailed descriptions are all illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0040] Embodiment 1

[0041] This embodiment provides a method for determining standard man-hours for equipment maintenance.

[0042] This embodiment provides a method for determining the standard working hours for equipment maintenance, such as Figure 1 As shown, the following steps are included:

[0043] Step 1: Classify and grade the processes.

[0044] First, the whole process of equipment maintenance is divided into six standard procedures: preparation, diagnosis, disassembly, installation, testing and finishing. Each type of standard procedure can be further subdivided into specific process contents, and each process content can be rated, which is divided into four levels: auxiliary process, ordinary process, key process and critical process. As shown in Table 1, there are differences in the qualification requirements for operators at different levels of processes, and the hourly price of operators with different qualifications is different. Regarding the content of the labor time quota, each equipment maintenance labor time quota is obtained by adding up the standard labor time of each process of the content. In this way, by calculating the standard labor time of each process, the labor time quota of the entire equipment maintenance can be determined in disguise.

[0045] The process can be deleted or added according to the actual fault handling situation, and the corresponding process level needs to be judged by the technicians. The process level determines only the upper limit of personnel qualifications. For example, the highest qualification of personnel for ordinary processes is intermediate workers. The number of people in each type of work is filled in Table 1 according to the actual situation. A, Β, Γ, Δ represent the number of people in each type of work.

[0046] Table 1. Classification level of fault handling process and personnel qualification and working hours

[0047]

[0048]

[0049] Step 2: Calculate the standard working hours of the process.

[0050] Considering the current situation, it takes time to accumulate actual working hours data, but settlement requires a reasonable quota of working hours. The supervisor requirement method in the experience evaluation method can be used to formulate a reference working time for maintenance of components of different complexity through review. Alternatively, the reference working hours are determined by using the MODAPTS method (Modular Arrangement of PTS), which uses intermediate work as a model, directly measures the first occurrence of a failure, and completes a certain amount of work at a normal working speed and in a standard working method under standard working conditions and environments, thereby determining the reference working hours. (n represents the number of the process), used in the standard working time formula.

[0051] Step 3: Calculate the standard working hours for key processes.

[0052] Equipment fault diagnosis is a key process in the fault handling process, and the reverse probability method is used here for calculation. First, the diagnostic process is divided into stages and paths. There may be multiple diagnostic paths in each diagnostic stage. In the actual fault diagnosis process, the operator may not immediately choose the correct path for each diagnostic stage. There is a troubleshooting process, but there are certain skill requirements for the operator, and it is not allowed to check every path in each diagnostic stage. Therefore, reverse reasoning is used here. After determining the correct path for each stage, an intermediate worker is selected to check the correct path according to the process and record the reference working hours. However, it is reasonable to choose the wrong path. Therefore, it is necessary to combine the probability while back-calculating. The probability of correct path selection in the first three stages of diagnosis is set to 50%, 70%, and 90% respectively. From the fourth stage onwards, the probability of correct path selection is required to be 100%. In summary, the actual working time t2 value selection principle of the diagnosis stage is shown in Table 2.

[0053] Table 2. Principles for selecting the actual working time t2 in the diagnosis phase

[0054]

[0055] Step 4. This embodiment uses the reference working time and actual working time balance method to calculate the standard working time for each process. The reference working time can be determined in two ways. In order to make the standard working time more in line with reality, it is necessary to use the actual working time to adjust the reference working time to achieve a more balanced standard working time.

[0056] Specifically, the reference working hours are continuously adjusted and revised based on the accumulated data. m represents the number of failures. The reference working hours are continuously adjusted according to the revised formula. Make adjustments.

[0057] Revised formula: Where m represents the number of failures. It represents the reference working time of the nth process after the last failure, and tnm represents the actual working time of the nth process after the mth failure. represents the reference working time of the nth process after the mth failure, It indicates the reference working time of the nth process after this failure, that is, the adjusted reference working time.

[0058] Step 5: Standard working hours formula:

[0059]

[0060] Note: when Will The value is 1.

[0061] when Will According to the actual calculated value.

[0062] 在 In this embodiment, after obtaining the working time quota (standard working time) f(t), the standard working time fee ＝ The formula of standard working hours × unit working hour price can be used to calculate the cost of the entire spare parts maintenance process.

[0063] After the working hour quota f(t) is determined, the next issue to be solved is the working hour price Q. The working hour price is affected by many factors. Here we mainly select three factors, such as personnel qualifications, statutory holiday time period and dispatch unit management commission, to calculate the working hour price Q.

[0064] (1) The impact of labor skills on the unit price of labor hours.

[0065] The skill level of the staff in the process of equipment failure handling directly affects the principal of the labor hour price. The skill requirements of the staff are made in combination with the process level. While ensuring the quality of fault handling, high-low matching (high-skilled personnel operating low-value processes) is avoided. According to the annual human resources market wage price and enterprise labor cost information of a certain province and city, as shown in Table 3, the median annual salary of personnel with corresponding skill levels is calculated according to the formula for the labor hour price principal as follows: Calculation of labor hour price principal W = S / (12*21.75*8). Note: S represents the median annual salary of personnel with corresponding skill levels, 12 represents a total of 12 months in a year, 21.75 represents the number of working days per month, and 8 represents the working hours per day.

[0066] Table 3: Salary levels of employees in enterprises by job level (unit: 10,000 yuan / year)

[0067]

[0068] (2) The impact of statutory holidays on the unit price of working hours.

[0069] At present, the working hour system implemented is that the daily working hours of workers do not exceed eight hours and the average weekly working hours do not exceed 44 hours.

[0070] For workers who are paid on a piece-rate basis, the employer shall reasonably determine their labor quotas and piece-rate remuneration standards based on the working hour system.

[0071] Employers shall ensure that employees have at least one day off per week.

[0072] The overtime pay standards in the local province are as follows:

[0073] Extended working hours: If the working hours are extended beyond the daily statutory standard working hours, overtime wages should be paid at a rate not less than 150% of the hourly wage base.

[0074] Overtime on rest days: When work is arranged on rest days (including Saturdays, Sundays and other statutory rest days), if compensatory leave cannot be arranged, overtime wages should be paid at a rate not less than 200% of the daily or hourly wage base.

[0075] Overtime on statutory holidays: When work is arranged on statutory holidays, overtime wages should be paid at a rate not less than 300% of the daily or hourly wage base.

[0076] According to regulations: when employees work night shifts, employers should pay night shift subsidies based on the employees' wages.

[0077] The specific subsidy standard is generally calculated based on 20% of the worker's daily wage, and the minimum is not less than 10% of the daily wage.

[0078] The calculation method for night shift pay subsidy is: night shift pay subsidy = daily salary × subsidy standard. The subsidy standard is generally 20%, and the minimum is not less than 10%.

[0079] Based on the general company situation, the day shift is 8:00-16:40, and there is no clear regulation on the night shift time period, which is tentatively set at 20:00-5:00.

[0080] The impact of statutory holiday periods on the hourly rate is that in different holiday periods, the principal of the hourly rate is multiplied by different multiples, as shown in Table 4.

[0081] Table 4. Multiples of the unit price of working hours in different time periods on statutory holidays (b)

[0082]

[0083]

[0084] (3) The impact of labor dispatch unit management fees on the unit price of labor hours.

[0085] The management fees of labor dispatch units mainly include labor relations management fees, social security and provident fund payment service fees, daily service fees, personnel recruitment fees, etc.

[0086] Specific charging standards: According to the scale of outsourcing, after on-site inspection, targeted accounting is carried out. Enterprises need to charge labor dispatch management fees according to the assessed industry qualification level standards, that is to say: the management fee charging standard of the first-level labor dispatch enterprise is 8-17% of the total salary of the dispatched employees; the management fee charging guidance price of the second-level labor dispatch enterprise is 8-14% of the total salary of the dispatched employees; the management fee charging standard of the third-level labor dispatch enterprise is 8-12% of the total salary of the dispatched employees; the management fee charging guidance price of the fourth-level labor dispatch enterprise is 8-10% of the total salary of the dispatched employees. The present invention adopts the minimum coefficient of 8% to adjust the principal of the unit price of working hours.

[0087] like Figure 2 As shown in the figure, after summarizing the above three factors, the labor skill specifies the labor hour unit price principal W, the statutory holiday period adjusts the labor hour unit price principal multiple b, and the labor dispatch unit management fee revises the labor hour unit price principal coefficient s. Thus, the formula of labor hour unit price Q is obtained: Q = b*W*(1+s).

[0088] Calculation of standard maintenance costs: Equipment failure maintenance costs are calculated by the standard labor hours x labor hour unit price, that is, the standard labor hours for each process stage x the sum of the corresponding labor hour unit price.

[0089] The present embodiment provides a method for determining standard working hours for equipment maintenance. With respect to the diagnostic process, the troubleshooting process is considered and the problem of not being able to troubleshoot every path is not allowed. The actual working hours are corrected using reference working hours, and the reference working hours are adjusted using actual working hours to achieve a more balanced standard working hours, which effectively solves the problems of large errors in standard working hours and uncertain equipment maintenance periods.

[0090] This embodiment provides a method for determining standard working hours for equipment maintenance, which controls working hours and avoids false reporting of working hours, thereby making equipment maintenance costs more reasonable.

[0091] The present embodiment provides a method for determining standard working hours for equipment maintenance, which adopts a method combining a scientific calculation method with actual process implementation to formulate a reasonable standard working hour quota.

[0092] The present embodiment provides a method for determining the standard working hours for equipment maintenance, which only requires manual determination of the process classification and grading, and can automatically calculate the maintenance cost based on the actual number of operators and the actual working time of each process.

[0093] This embodiment provides a method for determining standard working hours for equipment maintenance, which combines big data statistics to scientifically calculate the working hour unit price standard for personnel of different skill levels and makes skill requirements for different processes.

[0094] Standard working hours ensure that workers can receive reasonable compensation after working standard hours, which helps to safeguard the basic economic rights and interests of workers. Standard working hours help companies estimate and control production costs more accurately and avoid cost overruns caused by unclear working hours. By setting standard working hours, companies can motivate employees to improve work efficiency and reduce unnecessary waste of working hours, thereby improving overall operational efficiency. Based on the calculation of standard working hours, companies can allocate human resources and equipment resources more reasonably to ensure the smooth completion of production or maintenance tasks.
