The following data refers to the study conducted for an operation.Table shows actual times for element in minutes
Element 2 is machine element ,br>Consider the observation as abnormal and delete the same if they are more than 20% of average time of the element.
Take performance rating as 120
Assume following allowance:
Personal allowance=30minutes in a shift of 8 hours
Fatigue allowance=15%
Estimate the standard time of operation,normal time and work content.
| Elements | Cycle (Minutes) | |||
