Question

The normal time for a repetitive task that produced two work units per cycle is 3.0 min. The plan uses a PFD allowance factor of 15%. Determine (a) the standard time per piece and (b) how many work units are produced in an 8-hour shift at standard performance. (20 pts)

Answer 1

A.- 3.45 min to produce two work units

B.- In a 8-hout shift at standard performance 274 work units are produced

Step-by-step explanation:

The Standart tiem per piece would be:

`StandardTime=NormalTime*(1+PFD)`

Given your numbers it will be:

`3 * (1 + 0.15)= 3.45`

This is the time per cycle to produce 2 work units

Now, in an 8 hours shift there are 480 minutes. Dividing between the standard time of a cycle we get the standard performance

`(480)/(3.45) = 137.14`

Rounding, we will be getting 137 cycles

Lastly, because each cycle produce 2 work units we are having a total of 274 Units
