Answer:
Effectiveness = 0.75
Explanation:
Availability time for a each day = 10 hr = 600 minutes
Total time for fabricating is given as 90 minutes'
Total time to set up one part 10 minutes
Total parts made in each single day 5
Percentage of defective part 10%
Total production time for a single part = setup time + fabricated time
= 10+ 90 = 100 min
Production time for 5 part =5 × 100 = 500 minutes
Total number of defective parts = 10% of 5 = 0.5 parts
Time to replaced defective = 0.5 × 100 = 50 min
Value added time = 500 - 50 = 450 min
Effectiveness is given as
Effectiveness [tex]= \frac{value\ added\ time}{ total\ time\ taken}[/tex]
Effectiveness [tex]= \frac{450}{600} = 0.75[/tex]
