How Standard Work is Calculated The formula for calculating standard work

The working hour quota refers to the sum of the working time, preparation time, rest time and physiological time required to complete a qualified product in accordance with the product process under a certain technical state and production organization mode.

The fixed working hours and quotas should be based on the production and technical conditions of the enterprise, so that most workers can achieve it through hard work, some advanced workers can exceed, and a small number of workers can reach or approach the average advanced level through hard work.

A reasonable quota of working hours can mobilize the enthusiasm of workers and promote the improvement of workers' technical level. So as to continuously improve labor productivity. With the continuous improvement of the production technical conditions of the enterprise, the working hour quota is revised regularly to maintain the average advanced level of the quota.

Standard working hours = normal working hours + relaxation time (normal working hours = observed working hours * evaluation factors) (standard working hours = working time to produce a good product).

The conditions required to measure standard working hours are:

a, the operators are well-trained skilled operators, b, must be normal speed, c, all items are good, under the above conditions and then need to use the code meter to measure the time from the first process to the last process, repeated measurement to take the average.

Divide the resulting average by 85% to get the standard working hours. (Why 85% is taken because considering that people cannot be like machines, and our marriage rate needs to reach 85% under normal circumstances).

1. Stopwatch measurement method: Even if a stopwatch (also known as a computer meter) is used for direct measurement, general technicians are usually selected to work in a normal environment for time measurement.

2. There are also a variety of stopwatch measurement methods, you can choose to use a variety of measurement methods, and you can also choose continuous measurement; The established electronic standard (PTS) method of setting time standards (scheduled times) is to decompose the actions that make up a work unit into a number of basic actions, observe these basic actions in detail, and then develop a standard schedule of basic actions.

3. The model method decomposes people's various behaviors into 21 basic behaviors, and decomposes employees' work behaviors into corresponding behaviors when formulating standard working hours. and establish standard working hours based on the corresponding time of the corresponding action.

4. The basic action unit time in the model method is seconds, and according to the model method, the basic action unit time is seconds. Different conditions, such as proficiency, should be adjusted.

5. Brief Working Factor (BWF), BWF also decomposes various behaviors into basic motivations, the basic unit is BU, the time of each BU is seconds, and each motivation is 5 BU. By breaking down employee behavior into basic motivations, standard working hours can be calculated.

6. Other methods: In addition to the above methods, there are also standard working hours formulation methods such as MTM (standard method for predetermined action time) and WF (working coefficient method).

7. This refers to the theoretical method. In fact, the method of setting standard working hours can be used flexibly. For example, if you need to set standard working hours for a new model, you can set standard working hours for similar models in the past.

Standard working hours = standard working hours + auxiliary hours.

Analysis: Standard working hours are the labor time required to carry out a processing process in a standard working environment. There are several ways to set standard working hours, and the methods commonly used are:

Standard working hours = standard working hours + auxiliary hours.

The standard operating time is determined by the process and is mainly consumed by manual machine time that directly adds value to the product. The reduction of standard man-hours can only be achieved through process improvement and reduction of auxiliary time.

Direct observations

1. Stopwatch measurement method, that is, the method of using a stopwatch (also called a code watch) for direct measurement, usually selects general skilled employees to work in a normal environment to measure time; There are also several ways to measure with a stopwatch, with the option of using multiple measurements or the option of continuous measurements;

Predetermined Time Standards (PTS) is a standard timetable for decomposing the actions that make up a work unit into a number of basic actions, observing these basic actions in detail, and then making them into a standard schedule of basic actions.

2. Model method, that is, the various actions of the human body are decomposed into 21 basic actions, and when the standard working hours are formulated, the actions of the employees' operations are decomposed into the corresponding actions in the model law, and the standard working hours are formulated according to the corresponding time of the corresponding actions, and the most basic action unit time in the model method is seconds, which can be adjusted according to different conditions such as proficiency;

3. Brief Work Factor Method (BWF: Brief Work Factor), BWF is also to decompose various actions into basic kinematics, the basic unit is BU, the time of each BU is seconds, and each kineme is 5 BU, and the standard working hours are formulated by decomposing the employee's actions into the basic kinematics in BWF.

It's good to use MTM for analysis, so you don't have to do so much troublesome calculations.

Standard working hours. Calculation method: Standard working hours = normal working hours multiplied by (1 + relaxation rate); Relaxation rate = (standard working hours - measured working hours) Measured working hours multiplied by 100% = relaxation rate before the pipeline chain + physiological relaxation rate + fatigue relaxation rate; Normal man-hours are the sum of man-hours of manual operation unit (after speed evaluation) + man-hours of automatic operation of the machine (not for speed evaluation); The relaxation rate is mainly the sum of the following aspects:

1. Physiological leniency: generally take 2% 5%. 2 Fatigue Relaxation:

5% 20% for a shed of filial piety; 3 Management leniency: generally take 3% 10% 4 Special leniency rate The leniency rate used in the electronics manufacturing industry is generally 10%. Labor Law of the People's Republic of China.

Article 39 If an enterprise is unable to implement the provisions of Articles 36 and 38 of this Law due to the characteristics of its production, it may, with the approval of the labor administrative department, implement other methods of work and rest. Article 38 of the Labor Law of the People's Republic of China stipulates that employers shall ensure that employees have at least one day off per week. Article 36 of the Labor Law of the People's Republic of China stipulates that the daily working hours of workers shall not exceed eight hours and the average weekly working hours shall not exceed forty-four hours.

Legal Analysis: Standard Time Observation Time Evaluation Factor (1 Relaxation Rate) Normal Time (1 + Relaxation Rate) Observation Time: It is the average of the time value obtained from the actual observation, and the observation time is affected by the operator's proficiency, work willingness, emotion, etc., and can represent the real situation, so it should be corrected, multiplied by a certain evaluation coefficient, and the actual time should be considered as a certain relaxation, as a preparation for fatigue, waiting, drinking water, going to the toilet, etc. This is how you get the standard time.

Rating Coefficient: Appraisal is a technique of judging or evaluating the purpose of adjusting the actual operating time to the normal speed of the average worker.

Legal basis: Article 10 of the Labor Law of the People's Republic of China A written labor contract shall be concluded to establish a labor relationship. If a labor relationship has been established and a written labor contract has not been concluded at the same time, a written labor contract shall be concluded within one month from the date of employment.

If the employer and the employee conclude a labor contract before employment, the employment relationship shall be established from the date of employment.

Summary. Calculation method of standard working hours: standard working hours = normal working hours x (1 + relaxation rate); Relaxation rate = (standard working hours - measured working hours) Measured working hours * 100% = management relaxation rate + physiological relaxation rate + fatigue relaxation rate; Normal man-hours are the sum of man-hours of manual operation unit (after speed evaluation) + man-hours of automatic operation of the machine (not for speed evaluation); The relaxation rate is mainly the sum of the following aspects:

Can you give an example to elaborate?

What I'm asking about is the percentage of hours worked.

The achievement rate of shift time can be calculated according to the actual attendance time quota time * 100%.

Is it the total number of production hours divided by the quota time?

That's right. For example, the total working hours are 300 hours, and the quota time is 12 hours (300 12 100% = 25% working hours achievement rate?) ）

That's right.

Ok thanks.

You're welcome, please give a like, thank you.

The calculation of working hours needs to be understood from the perspective of the working hours system.

According to the existing situation, there are currently three working hours systems in China, namely the standard working hours system, the comprehensive calculation of working hours system, and the irregular working hours system. Standard working hours are one of the most widely used working hours system in China.

Under the standard working hours system, according to Article 36 of the Labor Law and Article 3 of the Provisions on the Working Hours of Employees, the maximum working hours of a worker per day is 8 hours, and the maximum working hours per week is 40 hours.

Comprehensive calculation of working hours. This type of working hours system is based on the standard working hours system and comprehensively calculates working hours based on a certain period of time.

According to Articles 5 to 7 of the Reply of the Ministry of Labor on Issues Concerning the Working Hours of Employees, this type of working hours system has the following characteristics:

Generally, the working hours are calculated comprehensively on a monthly, quarterly and annual basis;

The average daily working hours and the average weekly working hours shall be basically the same as the statutory standard working hours, that is, the actual working hours on a specific day (or week) may exceed 8 hours (or 40 hours) in the comprehensive calculation period, but the total actual working hours in the comprehensive calculation period shall not exceed the total statutory standard working hours.

In the case of a comprehensive calculation of working hours, regardless of the number of hours worked by the employee in normal times, as long as the total number of working hours in a comprehensive working hours calculation period does not exceed the total number of hours that should be worked under the standard working hours system, it shall not be regarded as overtime. If exceeded, the excess shall be regarded as extended working hours and remuneration shall be paid in accordance with the provisions of the Labor Law, and the number of hours of extended hours shall not exceed 36 hours per month on average.

The irregular working hours system refers to the working hours system that does not have a fixed commuting time limit for each working day, and is a working hours system adopted for employees who cannot be measured by standard working hours or need to work flexibly due to the relationship between production characteristics, special needs of work or the scope of responsibilities.

According to Article 67 of the Opinions on Several Issues Concerning the Implementation of the Labor Law of the People's Republic of China [1995] No. 309 of the Ministry of Labor, Article 8 of the Reply of the Ministry of Labor on Issues Concerning the Working Hours of Employees and Article 13 of the Interim Provisions on the Payment of Wages of the Ministry of Labor, this type of working hour system has the following characteristics:

Employees who have been approved to work irregular hours are not subject to the restrictions on the standard of daily and monthly extended working hours as stipulated in Article 41 of the Labor Law.

For employees who work irregular hours, the employer shall take appropriate rest methods to ensure the employees' right to rest and leave and production. Completion of work tasks.

The implementation of irregular working hours, except for statutory holidays, other hours of work are not counted as overtime.
