Question

The observed average time in a direct time study was 2.40 min for a repetitive work cycle. The worker’s performance was rated at 110% on all cycles. The personal time, fatigue, and delay allowance for this work is 12%. Determine the normal time and the standard time for the cycle.

Answer 1

Answer: a) 2.64 min b) 2.688 min.

Explanation:

Since we have given that

Average time in a direct time study = 2.40 min

Worker's performance on all cycles = 110%

Delay allowance for this work = 12%

So, the normal time would be

`2.40(1.10)=2.64\ min`

and the standard time would be

`2.40(1+0.12)\\\\=2.40* 1.12\\\\=2.688\ min`

Hence, a) 2.64 min b) 2.688 min.
