The production rate is an important indicator, the basis for the planned management of the enterprise. It defines the number of units of production (or the number of operations performed) that must be manufactured (or performed) per unit of time. The calculation of the production rate is carried out for one or a group of workers with the appropriate qualifications, with the optimal and most rational use of equipment, taking into account the progressive methods of work applied.
Instructions
Step 1
For mass and large-scale production, characterized by taking into account the labor of special workers employed in preparatory and final work, the time rate for the manufacture of a unit of production is equal to the rate of piece-calculation time. For piece, serial and small-scale production, when the same employee performs the main, preparatory and final work, these time rates will be different.
Step 2
When calculating the production rate, which expresses the necessary result of the activities of workers, natural indicators are used: pieces, meters, kilograms. The production rate (Nvyr) is the quotient of dividing the duration of one work shift (Wm) by the time spent on the manufacture of a unit of production (Wsh). For mass production, the production rate will be equal to:
Nvyr = Vsm / Vsht.
Step 3
If the production is batch or one-to-one, then the value Vshtk is used as a divisor in the above formula - the rate of time determined by the calculation method when calculating the cost of a unit of production. In this case, the production rate is calculated by the formula:
Nvyr = Vsm / Vshtk.
Step 4
In those industries where the preparatory stage is calculated and standardized separately for each work shift, the production rate should be calculated using the formula:
Nvyr = (Vsm - Vps) / Tsm, where Vs is the time spent on preparatory and final work.
Step 5
The formula for calculating the production rate in cases of using automated and hardware equipment will be slightly different:
Нvyr = Ho * Нвм, where Ho is the maintenance rate, Нвм is the equipment production rate, which is equal to:
Нвм = Нвм theor * Кпв. Here Нвм theor is the theoretical rate of production of the equipment used, Кпв is the coefficient of useful labor time per shift.
Step 6
In the case of using periodic instrumental processes, the production rate is equal to:
Нvyr = (Vsm - Vob - V ex) * VP * Ho / Vop, where V rev is the time spent on equipment maintenance, Votl is the time rate for personal needs of personnel, VP is the products produced in one period, Vop is the duration of this period …
Step 7
The rate (P) can be calculated using the formulas:
P = C / Nvyr, or
P = Vsht * C, where C is the rate of this category of work.
