Given the bill of material for the printer cartridge (A) shown below, a gross requirement to build 170 units of A, on-hand inventory levels for each item as shown in the table below and assuming zero lead times for all items A, B, C, D, and E, compute the net requirement for each time. Item On-Hand Inventory 50 50 90 70 15

Explanation / Answer

for each item A , we require following qtt of

B=1 or D =1

C= 1 or D=2 + E=1

1 B + 1 C = 1A

hence 50 B will produce 50 A

C left =40

B left =0

Now D =70 which can help in production of B

Hence we can make 40 A from 40 C + 40 D

C left =0

B left =0

D left =30

E left =15

A on hand = 50 + 50 +40 =140

Now 3D + 1E = A

hence we require 10 E + 30 D to make 10 more A

hence A on hand = 140+10 =150

E left =5

B=C=D =0

We require inventory of 20 more A

Hence Final Requirement

E =20-5 =15, and

D =3*20 =60

This requirement can be further changed into the requirement of B and C also
