Real working time fund formula. Planned effective working time fund. Calculation of the total cost of fixed assets

To determine the number of main production workers, it is necessary to calculate the effective working time fund of one average worker, which is determined on the basis of the working time balance.

The balance of working hours is drawn up in three stages.

At the first stage, the nominal (useful) working time fund in days is determined.

To do this, holidays and weekends are deducted from the calendar fund (365 days), we get the personnel fund of working time. at a conditional enterprise, the personnel fund will be:

F tab = 365 - 69 = 296 days

By subtracting planned absences from work from the personnel fund, a useful working time fund is determined. Absenteeism, according to the Labor Code of the Russian Federation, includes: regular, additional, study leave, maternity leave, absenteeism due to illness, in connection with the performance of state duties (retraining of men who are in the reserve of the Russian Army, participation in court hearings, in elective campaigns). For a conditional enterprise, the useful working time fund will be:

F floor \u003d 296 - 38 \u003d 258 days

At the second stage, the average length of the working day is determined, adjusted for the shortened working day on holidays. At the reference enterprise, the average working day is 7.87 hours.

At the third stage, the effective working time fund of one average worker is calculated by multiplying the useful working time fund in days by the average working day in hours. For a conditional enterprise, the effective working time fund of one average worker will be:

Fr. temp. = 258 * 7.87 = 2030.46 hours.

The calculation results are presented in Table 2.

Table 2.

The balance of working time of one average worker

Calculation of the number of personnel

Human Resources(personnel) of the enterprise are the main resource of each enterprise, the quality and efficiency of the use of which largely determine the results of the enterprise and its competitiveness. Labor resources set in motion the material

material elements of production, create a product, value and a surplus product in the form of profit.

Personnel of the enterprise directly related to the production process of products (services), i.e. employed by the main production activities, represent the industrial and production personnel of the enterprise.

Its composition includes:

l workers;

l managers;

l specialists;

b employees.

Workers, in turn, are divided into two groups: production (main) and auxiliary. The first group includes all workers attached to production equipment and performing all technological and transport operations in the production process. The second group (auxiliary) includes workers performing loading and unloading, repair, transport and other work.

Managers are employees who leadership positions enterprises and their structural divisions, as well as their deputies (director, chiefs, managers, managers, chief specialists ( Chief Accountant, Chief Engineer, chief economist), etc.).

production program calculation savings

Specialists are employees engaged in engineering, technical, economic, accounting, legal and other activities.

The calculation of the number of main workers is based on

the labor intensity of the production program and the effective working time fund according to the following formula:

where Tpr. pr. - labor intensity of the production program, n. - hours;

Fr. temp. - effective fund of working time of one average worker, hours;

K in. n. in. - coefficient of fulfillment of the production norm.

The labor intensity of the production program is determined by the formula:

Tpr. pr. \u003d Q "*t, n. - h.,

where t is the labor intensity of a unit of production, standard hour.

For the conditional enterprise, the following data is available:

t = 24.4 standard hour.

Then the complexity of the production program will be equal to:

Tpr. pr. \u003d 24696 * 24.4 \u003d 602582.4 standard hours.

Thus, in order to complete the production program

(the total time spent for its implementation is 602582.4 standard hours)

the enterprise when the output norm per worker is 1.17% and

an effective working time fund of 2030.46 hours, 254 people are needed.

The number of auxiliary workers, managers and specialists is determined as a percentage of the number of main workers.

Thus, the number of auxiliary workers is 9% of the main (23 people), managers - 3% (8 people), specialists - 7% (18 people). The total number of PPP of the conditional enterprise will be 303 people.

The calculation of the number of industrial and production personnel of the enterprise is presented in table 3.

Table 3

Calculation of the number of PPP

Fe is defined as the difference between the nominal fund and the projected costs for repair, adjustment and readjustment of equipment during the year

Fe=Fn (1- ) (9.14)

where Cr- standard time spent on repair, adjustment and readjustment of equipment as a percentage of the nominal fund;

The annual (effective) fund of the equipment operation time is the equipment operation time during the year, expressed in hours.

Fn \u003d ((Dk-P-V) Ps-Dpv ΔPs) S (9.15)

where Dk– 365 days a year;

P- amount public holidays per year (10 days);

AT- the number of days off in a year - 104 days (52 Saturdays and 52 Sundays);

Ps- the duration of the shift;

dpv- the number of pre-weekend and pre-holiday days with a reduced shift duration;

ΔPs- the time by which the nominal duration of the work shift is reduced (usually 1 hour);

C is the number of working shifts per day.

Rounding up

Equipment load factor:

where N calc. - the estimated amount of equipment;

N app. - accepted amount of equipment.

The following minimum values ​​are recommended K s: with intermittent operation - 0.93; in continuous mode - 0.85. If the value K s does not satisfy the above restrictions, then it is necessary to choose equipment of a different or the same type, but with different technical specifications. However, it should be remembered that an increase in the extensive load factor due to the selection of obsolete low-performance equipment is unacceptable, since this significantly worsens the economic performance of production.

All calculations to determine the required amount of equipment are recommended to be made in the form of a table .

Features of calculating the required amount of equipment in in-line production.

When designing production lines, the required number of pieces of equipment for each operation of the process is calculated based on a single rhythm of the production line according to the formula:

H=t pcs:r(9.17)

H=1:(r R)(9.18)

here t pcs- the norm of piece time. in oven-hours (unit-machine-hours) for processing a unit of product for i-th opsrations;

r- the rhythm of the production line;

R- performance of a piece of equipment per i-th operations during effective business hours.

The rhythm of the single-subject production line is calculated by the formula:

r=F e.l:Q(9.19)

where F e.l- effective time fund of the production line, h;

Q- annual volume of processing of products of this type, units.

When calculating the effective fund of the line, it should be taken into account that equipment repairs can be carried out with or without downtime of the entire line. Repair of equipment certain types can be carried out without stopping the line in the case when the creation of the necessary reserves for the relevant types of equipment is provided. If the entire line is stopped for repairs, then its downtime (due to repair) is determined by the downtime of that equipment, the duration of which is the maximum repair.

The rhythm of the work of a multi-subject variable-flow line is calculated for each type of product. The required amount of equipment for each operation on such a line is taken for the product for which the estimated amount of equipment is maximum.

10. choice of building type and equipment layout

When implementing a project for a new division, equipment for heat treatment located in an industrial frame building. It is necessary to start planning with the choice of the width of the span, depending on the size of the equipment and the number of rows of equipment along the span, taking into account the allocation of the necessary free lanes between the rows of equipment for its maintenance, as well as for the passage service personnel, and if necessary - for the passage of transport. For auto and electric cars, the passage should be 2 ... 2.5 m, for cars - 3 ... 3.5 m and for railway cars - 6 m. also between walls (columns) and extreme rows of equipment.

After selecting the span width (the width must be a multiple of six, i.e. 12, 18 ... 42 m), a grid of columns (a system of longitudinal and transverse center lines) is applied to the sheet and cross sections of the columns are drawn at the intersection of the center lines. In industrial buildings, reinforced concrete or steel columns are used. An example of their image on the section of the building is shown in fig. 10.1. Figure 10.2 shows a general view of an industrial building.

Figure 10.1 - Reinforced concrete (a, b) and steel columns (c) and building structural elements interacting with them: I - farm; 2 - window beam; 3 - crane beam; 4 - reinforced concrete columns; 5 - window opening: 6 - foundation beams for supporting walls; 7 - column foundation

After drawing the grid and sections of the columns, the equipment is placed on the production site and tied to the nearest axes of the columns, i.e. dimensioning from the longitudinal and transverse axes to the contour. On technological layouts, equipment is depicted by contour lines, to a certain extent reproducing the contours of this equipment in plan, i.e. when viewed from above. The accepted symbols of the equipment are shown in fig. 10.3.

Figure 10.2 - General views industrial building structures

When arranging equipment on a plan, the main attention should be paid to the organization of a clear directional movement of products so that there are no opposite movements of products (and it is desirable to exclude intersecting flows), the location of the equipment should be in the sequence in which technological operations are performed. For example, in thermal improvement, a hardening furnace should be installed at the beginning of the row, then a hardening tank, followed by a washing machine (bath), then a tempering furnace, then a tank for cooling parts after high tempering, a press for straightening products, etc. In mass and large-scale production, all equipment necessary for carrying out the technological process is aggregated, i.e. they are connected by a single inseparable transport system that provides fast, most often automatic transfer of products from one type of equipment to another, from another to a third, etc.

Inside the unit, the movement of parts can be in a closed loop, which eliminates the need to return pallets, as is the case with linear (on-line) units. Non-aggregated equipment should be spaced from each other at a certain distance, providing ease of maintenance and repair of equipment. When planning equipment, it is necessary to provide sites (they are depicted by dashed lines) for placing raw (not heat-treated) products, sites for control and acceptance finished products OTK. storage areas for finished products, etc.

If a reconstruction project is being carried out, then the layout of the equipment existing in the basic thermal division should be analyzed in order to identify shortcomings and, if possible and appropriate, eliminate them by rearranging some of the units. In cases where some of the obsolete units are replaced by more advanced units, new pieces of equipment must be installed on the vacated area in compliance with the same standards that are followed when planning a new thermal unit.

Efficient working time fund(more precisely, the planned effective working time fund) is the estimated value of working time that can be used for the effective implementation of the enterprise's labor operations.

To determine the value of the planned effective fund of working time, the calendar fund of time is taken as a basis. The value of calendar time is reduced by the number of days off in a year (if the mode of operation of the enterprise implies them), resulting in the value of the personnel (nominal, standard) working time fund. But also this fund working hours cannot be used in full for the performance of labor operations. The resulting value of the working time fund should be reduced by the duration of vacations, absenteeism due to illness, the time of execution of state duties, etc. And only the time value obtained, reduced for the indicated purposes, can be planned as possible for the performance of labor operations.

The planned effective working time fund (Trv) is less than the maximum possible fund by the amount of planned absenteeism of workers for good reasons (absence from work due to illness and childbirth, time to perform state and public duties, the duration of study holidays, etc.). The duration of the planned effective working time fund can be determined on the basis of the working time balance using the following formula:

Trv \u003d (Tk - Tv - Tprz - To - Tb - Tu - Tg - Tpr) × Psm - (Tkm + Tp + Ts) (person / hour),

Where Tk is the number of calendar days in a year;

TV - the number of days off in a year (according to labor law);

Tprz - the number of holidays in a year (again, in accordance with labor legislation, it is necessary to take into account how the legislation regulates the coincidence of weekends and holidays. For example, in Ukraine, if a holiday falls on a weekend, it is transferred to the first next working day. Then there are holidays and weekends are mathematically summed up);

That is the duration of the next and additional holidays(days). In this case, it is necessary to take into account the average value for the division or enterprise, since a number of employees may have benefits regarding the duration of paid leave;

Tb — absence from work due to illness and childbirth (days). This value is determined statistically by the enterprise;

Tu is the duration of study holidays (days). This value is determined statistically by the enterprise;

Tg - time for the performance of state and public duties (days). This value is determined statistically by the enterprise;

Tpr - other absences permitted by law (days);

Psm - the duration of the work shift (hours);

Tkm - loss of working time due to the reduction in the length of the working day for nursing mothers (hours);

Tp - loss of working time due to the reduction in the length of the working day for adolescents (hours);

Тс - loss of working time in connection with the shortened working day on holidays (hours).

The number of non-working days for valid reasons (Tb, Tu, Tg, Tpr, Tkm, Tp) is determined, as a rule, on the basis of the average data of the report for the past year and in accordance with labor legislation.

For reference: Typically, the indicated loss of time is about 12% of the normative fund of working time. Therefore, for rough calculations for the transition to effective working time, a factor of 0.88 can be used. Please note that this figure represents the statistically prevailing in the engineering industry, in which the author of this article has worked for a long time. Therefore, for your particular company, it may differ.

An important aspect is the use of the calendar fund of working time. This concept includes the calculation of the period under consideration with the greatest efficiency of each of the employees. Since the main goal of the employer is to use all resources with maximum efficiency, the organization of the labor process is one of the most important aspects of planning.

Using the calendar fund of working time

The use of the calendar fund is aimed at effective planning and compilation work time balance. This concept includes a set of indicators that are calculated using various formulas.

The following standards can be considered:

• the calendar fund is the total period during which the calculation is carried out; for this, a year is usually taken into account;
• nominal - the number of days in a year that remains after subtracting all weekends and holidays from the calendar period;
• the maximum possible - the statutory leave is deducted from the nominal indicator according to the formula;
• attendance - here those days are taken into account on which the employee, for good reasons, cannot come to work.

In addition to these points, when planning, the employer can also calculate the predicted downtime.

Each of these concepts is used in the calculation of coefficients or other indicators of labor efficiency. For the formula in this case, the actual data and their correlation with the predicted ones are taken. The result obtained is used to take measures to improve labor efficiency.

Nominal working time fund

The nominal or personnel fund of working time is calculated according to a simple formula - holidays and weekends are deducted from the calendar indicator. To calculate this indicator for the current year, use production calendar for 2018 .

The nominal figure is based on the calendar period that is taken into account. He can be:

• annual - such a calculation is carried out for large-scale studies of the effectiveness of the work of employees;
• quarterly - this option is often used when summarized accounting of working hours;
• monthly - this indicator is most relevant when calculating wages and identifying the ratio of turnouts to the rate of production.

Compilation of a nominal indicator should focus on a specific goal. According to the tasks set, the data entered into the formula may vary. For example, the work schedule may differ in winter and summer for greater efficiency labor.

The maximum possible fund of working hours

The maximum possible fund is calculated according to the formula by subtracting the vacation due to the employee from the nominal period. As a result, the predicted production remains, which becomes the general standard. This indicator is used to determine the required number of employees.

To do this, analyze the time spent by the employee on the performance of their duties. It is compared with the production need - the time for which the organization must cope with the tasks. According to the ratio, the staff is formed.

The formula for finding the maximum possible fund of working time is influenced not only by the standard indicator of labor, but also by the time at which the employee goes on vacation. There are some nuances here that are consistent with work days and weekends.

For example, an employee is registered for a period when, according to the calendar, there are already many holidays. His labor rate, accordingly, will be more time than that of an employee who seeks to take a vacation with the capture of a predominantly working period.

Security Fund

The attendance fund of working time is formed on the basis of subtraction from the maximum possible total indicator of personal reasons for not showing up for work. In this case, in general formula the following points may be included:

• maternity leave or parental leave;
• student leave;
• agreement with the manager.

That is, in this situation, aspects are taken into account when, under the law, an employee has objective reason not show up for work.

In this case, individual provisions of an individual employment contract. For example, during employment, it was agreed in advance that this employee an additional week of paid leave will be granted.

Efficient working time fund

An effective fund is formed on the basis of the number of employed employees. It is calculated on the basis of such indicators as man-hours and man-days. Similar concepts characterize the norms of production for certain actions.

For example to complete the order of the organization you need to spend 400 man-hours. If one person is accepted for work, then according to the ratio formula, he must work all 400 hours on his own, which, with eight hours of work, is 50 days.

However, the customer will not wait for such a period. Therefore, the manager increases the number of employees to 10. In this case, each has 40 hours, therefore, all work, with an effective distribution of duties, will take 5 days.

Planning the effective number of employees is the task of the manager. The calculation is based on development priorities and available opportunities. If in the same example we consider a simple one, when the employer cannot provide the supply of the necessary resources within 5 days, then it makes no sense for him to increase the staff.

Analysis of the use of the working time fund

An analysis of the use of the working time fund determines the organization's development strategy. The more efficiently it is distributed, the better productivity employees show.

Various data and indicators are used for analysis. Watching individual worker or a division can be carried out through pictures of working hours. It helps to analyze all labor process and time spent on each activity.

The main task of observing and analyzing the situation is to eliminate loss of working time. This concept includes those actions that are carried out during work, but are not aimed at the direct performance of duties. Eliminating waste helps improve work efficiency and performance.

To calculate the number of production and auxiliary workers, drivers, management personnel, work posts, technological equipment required by the enterprise needs to know the annual time funds of workers and equipment. Among them, there are annual funds for the time of an attendant and full-time worker.

The secret worker's time fund is the annual number of hours that a worker of the corresponding specialty must work without taking into account the loss of working time for vacation and for good reasons.

The time fund of a full-time worker is the annual number of hours that a worker must work at a given workplace, taking into account the loss of working time on vacation and for good reasons.

The number of production workers is determined for each type of technical impact, according to production sites and zones. The calculation is carried out on the basis of the labor intensity of the work and the time funds of the workers. Technologically necessary

where TI is the annual volume of work (labor intensity) of the corresponding zone of maintenance, TR, workshop, separate specialized post or diagnostic line, man-hour;

Fi is the annual productive fund of the workplace time, h.

The annual fund of time for an attendant worker (FT) is determined by the duration of the shift (based on the length of the working week) and the number of working days in a year.

For normal working conditions, a 40-hour working week is established, and for harmful working conditions, a 35-hour one.

Based on the duration of the working week, the duration of the working shift is 8 hours for 5-day working weeks for industries with normal conditions labor and 7 h with harmful.

The annual time fund of an attendant worker is determined by the duration of the shift (based on the length of the working week) and the number of working days in a year:

(38)

where CHN - the duration of the worker during the week, h;

Days - the number of working days in a week;

Dk, Dv, Dp - the number of days in a year, respectively, calendar, weekends, holidays

We accept Dk = 365 days; Dv = 104 days; Dp = 9 days;

tsk = reduction in the duration of the shift on pre-holiday days, h.

=2007 h

The annual fund of time for an attendant worker working in hazardous conditions:

=1764 hours

The annual time fund of a full-time worker (Fsh) determines the time practically worked out by the performer at the workplace. It is less than the fund of an attendant worker by the amount of the duration of vacations and absenteeism provided to workers for good reasons (illness, etc.):

(39)

where To - the duration of the worker's vacation, days;

D.p. - the number of days absent from work for good reasons;

The annual fund of time of a full-time worker of the main professions:

=1807 hours

Annual fund of time of a full-time worker working in hazardous conditions:

=1580 hours

The number of production workers, determined by formulas (38), (39) is given in Table. fourteen.
