Hello some parts of your question is missing attached below is the missing part
Answer : value added times : 30 minutes , 30 minutes
non-value added times: 1210 minutes, 130 minutes
Total lead times : 1240 minutes, 160 minutes
value added time as a ratio: 2.4%, 18.8%
Explanation:
Given data:
production batch sizes = 40 units
process step 1 = 6 minutes
process step 2 = 10 minutes
process step 3 = 6 minutes
process step 4 = 8 minutes
Determining : The value added, non-value added , total lead times and value added ratio under the present and proposed production approaches
UNDER PRESENT PRODUCTION APPROACH
Th value added time:
= summation of all process times = (6+10+6+8) = 30 minutes
Non-value added time:
= Value added time *(Batch size -1) + move time between each step
= 30*39+8*5
= 1170 +40 = 1210 minutes
total lead time :
= value added time + non-value added time
= 30 + 1210 = 1240 minutes
value added time as a percentage/ratio
(value added time / total lead time) * 100
= 30 / 1240 * 100 = 2.4%
UNDER PROPOSED PRODUCTION APPROACH
value added time :
= summation of all process times = (6+10+6+8) = 30 minutes
Non-value added time :
= Value added time *(Batch size -1) + time between each step
= 30*4+2*5 = 120 + 10 = 130 mins
total lead time :
= value added time + non-value added time = 30 +130 = 160 mins
value added time as a percentage/ratio:
(value added time / total lead time ) * 100
= (30 / 160) * 100 = 18.8%
