Answer:
(a) 450 minutes
(b) 275 minutes
(c) 725 minutes
Step-by-step explanation:
Given,
Number of units in one batch = 25
move time for raw materials to Cutting Department per unit =6 minutes
Time taken by Cutting Department per unit = 4 minutes
move time to Sewing Department per unit = 3 minutes
Time taken by sewing Department per unit = 10 minutes
move time to Packaging Department per unit = 2 minutes
time taken by packaging Department per unit = 4 minutes
(a) value added time for one unit = Time taken by Cutting Department per unit
+Time taken by sewing Department per unit
+time taken by packaging Department per unit
= (4 + 10 + 4) minutes
= 18 minutes
Value added time for 25 units = 18 x 25
= 450 minutes
(b) within batch wait time per unit =move time for raw materials to Cutting department per unit +move time to Sewing Department per unit +move time to Packaging Department per unit
= (6+3+2) minutes
= 11 minutes
Total within batch wait time = 11 x 25
= 275 minutes
(c) total lead time for batch = Value added time for 25 units
+Total within batch wait time
= 450+ 275
= 725 minutes
