Question

1. Визначити чисельність основних і допоміжних робітників, якщо річний випуск виробів заводу становить: машина ―МА 1 – 2 200 шт. із нормою часу на виріб – 490 нормо-год, машина ―МБ 2 – 150 шт. із нормою часу на виріб – 800 нормо-год. Норми робітники перевиконують на 20%. Невиходи на роботу плануються у розмірі 10%. Робочих днів – 258, тривалість робочої зміни – 8,2 год. Чисельність допоміжних робітників – 40% від чисельності основних робітників.

Answer 1

Calculating the Number of Main and Auxiliary Workers

To calculate the number of main and auxiliary workers, we can use the given information about the annual production output and the norms for each machine.

- The annual production output for machine MA1 is 2,200 units with a norm of 490 standard hours per unit. - The annual production output for machine MB2 is 150 units with a norm of 800 standard hours per unit. - Workers exceed the norms by 20%. - Planned absenteeism is 10%. - There are 258 working days with a duration of 8.2 hours per shift. - The number of auxiliary workers is 40% of the number of main workers.

Calculating the Number of Main Workers

First, let's calculate the total standard hours for each machine: - For machine MA1: 2,200 units * 490 standard hours/unit = 1,078,000 standard hours - For machine MB2: 150 units * 800 standard hours/unit = 120,000 standard hours

Now, let's factor in the 20% excess work and the 10% planned absenteeism: - Total standard hours for MA1 after excess work: 1,078,000 * 1.20 = 1,293,600 hours - Total standard hours for MB2 after excess work: 120,000 * 1.20 = 144,000 hours - Adjusted total standard hours for planned absenteeism: 1,293,600 + 144,000 = 1,437,600 hours

Next, we calculate the total available standard hours for the workers: - Total available standard hours: 258 days * 8.2 hours/day = 2,115.6 hours

Finally, we calculate the number of main workers needed: - Number of main workers = Total available standard hours / Adjusted total standard hours - Number of main workers = 2,115.6 / 1,437,600 ≈ 1.47 workers

Calculating the Number of Auxiliary Workers

The number of auxiliary workers is 40% of the number of main workers: - Number of auxiliary workers = 40% * 1.47 ≈ 0.59 workers

Conclusion

Based on the given production output, norms, excess work, and planned absenteeism, the calculated number of main workers is approximately 1.47, and the number of auxiliary workers is approximately 0.59.
