Question:-
A new facility has to be designed to do all the welding for 3 products: A, B and C. Per unit welding time for each product is 20 s, 40 s and 50 s respectively. Daily demand forecast for product A is 450, for B is 360 and for C is 240. A welding line can operate efficiently for 220 minutes a day. Number of welding lines required is
Option (A)
5
Option (B)
4
Option(C)
3
Option(D)
2
Correct Option:
(C)
Question Solution:
Time required to weld product (A)
(20/60) x 450 = 150 mins
Time required to could product (B)
(40/60) x 360 = 240 mins
Time required to could product (c)
(50/60) x 240 = 200 mins
Total time required = (150 + 240 + 200) = 590 minutes
Number of welding lines required = (590/220) = 2.68 ~ 3.
