Determining the amount of bench.
In the case of multi-series production, the number of machines is calculated by the following formula;
C = ;
Here: K - reset coefficient; K = 0.95
F = 4029 hours for 2 shift work;
Based on the calculations, the number of machines received is reduced to the nearest whole number and the number of machines accepted C is determined t - where the calculation time of the detail for each operation;
1.C = = 0,33 we accept C =1
2.C = = =0,306 we accept C =1
3. C = = =0,59 we accept C =1
4.C = = =0,20 we accept C =1
5.C = = =0,32 we accept C =1
6.C = = = 0,278 we accept C =1
Here: C is the number of machines accepted
In each operation, we find the load factor of the machine with the following formula;
K = = ;
K = =
K = = ;
K = =
K = = ;
K = =
The coefficient of utilization of machines on the main time is calculated by the following formula.
K = = =0,22;
K = = =0,38
K = = =0,42
;K = = =0,24
K = = =0,52;
K = = =0,26

Number of workers and employees.
In the case of medium-series production, the number of key employees in enterprises is calculated based on the number of machines accepted.
r = 6 people x2shifts = 12 people.
The number of key employees will increase by 12-15% of the number of participating employees:
R =12x0,15=1,8 people. R =1 we accept.
1 +12=13 people.
In the case of medium series production, the number of plumbers is assumed to be 1-3% of the number of key workers,
r =14x0,03=0,42 we accept 1person
Total number of employees involved in production:
R =13+1=14 people
The number of support staff is 30-40% of the total number of key employees.
r =13 x0.3=3.9 we accept 4 people
Total number of workers:
r =18 people
Engineers and technicians are hired at the rate of 12-15% of the number of key employees.
MTH=20 x0,15=3 people, we accept 4 people
Warehouse and office staff are hired at a rate of 5-6% of the number of key employees.
OIH=20x0,05=1 person, we accept 1 person
Junior service workers are hired at a rate of 1.5-2% of the total number of employees.
KXKH=20 x0,02=0,4 we accept 1 person
