A time study analysis shows an assembly operation for 50 cycles with an average cycle time of 15.00 minutes. If you assigned a performance rating of .95 and a work-day allowance factor of 20 percent, answer the following question:
What is the Allowance Factor?
Homework Answers
As we see, a work day allowance factor is 20 percent = 0.2
But there are two ways in which this will be used:
- Standard Time = Normal Time / ( 1 - Allowance)
- Observed Time = Standard Time / (Performance rating)(1 + Allowance)
Hence, there will be two allowance factors.
While calculating Standard Time, Allowance factor = 1 - 0.2 = 0.8
And for Observed Time, Allowance factor = 1 + 0.2 = 1.2

A worker-machine operation was found to involve 40 minutes of machine time per cycle in the course of 40 cycles of stopwatch study The worker's time averaged 25 minutes per cycle, and the worker was given a rating of 115 percent machine rating is 100 percent). Midway through the study, the worker took a 10-minute rest break. Assuming an allowance factor of 15 percent of work time which is applied only to the worker element not the machine element), determine...

A worker-machine operation was found to involve 3.6 minutes of machine time per cycle in the course of 40 cycles of stopwatch study. The worker’s time averaged 2.1 minutes per cycle, and the worker was given a rating of 111 percent (machine rating is 100 percent). Midway through the study, the worker took a 10-minute rest break. Assuming an allowance factor of 11 percent of work time which is applied only to the worker element (not the machine element), determine...

An initial time study resulted in an average observed time of 2.2 minutes per cycle, and a standard deviation of 0.3 minutes per cycle. The performance rating was 1.20. What sample size, including the 20 observations in the initial study, would be necessary to have a confidence of 95.44 percent that the observed time was within 4 percent of the true value?
