1. The normal time to perform the regular work cycle for a certain manual

operation is 3.23 min. In addition, an irregular work element whose normal time

is 1:25 min must be performed every 5 cycles. The PFD allowance factor is 15%.

Determine

(a) the standard time

(b) how many work units are produced if the worker's performance in an 8-hour

shift is standard.

2. Determine the anticipated amount of time lost per 8-hour shift when an

allowance factor of 15% is used, as in the previous question.

3. Now that the standard is set (T= 4.00 min) and given the data from the previous

questions how many work units would be produced if the worker's average

performance during an 8-hour shift were 125% and the hours worked were

exactly 6.956 hour, which corresponds to the 15% allowance factor.
