Question

Jefferson Company's demand for its only product exceeds its manufacturing capacity. The company provided the following information for the machine whose limited capacity is prohibiting the company from producing and selling additional units.
Actual run time this week 5,696 minutes
Machine time available per week 6,400 minutes
Actual run rate this week 1.68 units per minute
Ideal run rate 2.00units per minute
Defect-free output this week 12,670 units
Total output this week (including defects) 18,100units
Required:
1. Compute the utilization rate. (Round your answer to 2 decimal places.)
2. Compute the efficiency rate. (Round your answer to 2 decimal places.)
3. Compute the quality rate. (Round your answer to 2 decimal places.)
4. Compute the overall equipment effectiveness (OEE). (Do not round intermediate calculations. Round your final answer to 3 decimal places.)

Answer 1

Answer:

1. Utilization rate = Operating time/Scheduled time

Utilization rate = 5,696/6,400

Utilization rate = 0.89

2. Efficiency rate = (Total output / Ideal run rate) / Operating time

Efficiency rate = (18,100/2) / 5,696

Efficiency rate = 9,050 / 5,696

Efficiency rate = 1.5888343

Efficiency rate = 1.59

3. Quality rate = Good units produced / Total units produced

Quality rate = 12,670 / 18,100

Quality rate = 0.70

4. Overall Equipment Effectiveness = Utilization rate * Efficiency rate *  Quality rate

Overall Equipment Effectiveness = 0.89 * 1.59 * 0.70

Overall Equipment Effectiveness = 0.99057

Overall Equipment Effectiveness = 0.991
