Question: Following information is available from a snap back time study conducted on a Universal Milling machine. Machines do not need any allowances. Average observed manual
Following information is available from a snap back time study conducted on a Universal Milling machine. Machines do not need any allowances.
- Average observed manual time = 15 min
- Average observed milling time (automated) = 3.05 min
- Performance rating of the operator = 95%
- Personal and fatigue allowance = 15%
- Cycle time = Manual time + Machine time
- Operator produced only 36 products in 12 hour shift
- If the operator produces 36 of such products per 12-hour shift, what is the effective labor time?
-
- 500 minutes
- 600 minutes
- 700 minutes
- 800 minutes
- None of the above
- If the operator produces 36 of such products per 12-hour shift, what is the efficiency of this operator?
-
- 95.4%
- 96.0%
- 97.2%
- 98.5%
- 100%
