Question

Which of the follwoing for a-j is true? The following information is available for an MRP problem. The BOM file shows that Product A is made of one unit of Part B, two units of Part C, and three units of Part D. Part C is made of two units of Part E and three units of Part F. Checking the correct statements results in earning credits, while checking incorrect statements results in losing a half of a correct statement.

Item	Quantity (in millions)	Lead Time (periods)
A	4	1
B	5	5
C	2	2
D	3	4
E	4	3
F	20	2

The Master Production Schedule requirements for the finished product are as follows (in millions):

Period		p1	p2	p3	p4	p5	p6	p7	p8	p9	p10
A		0	0	0	0	0	1	4	8	4	6

	a.	net requirement for B in period 8 is 6.
	b.	planned order releases for F in period 2 is 0.
	c.	on hand inventory for F in period 4 is 0.
	d.	net requirement for E in period 5 is 28.
	e.	gross requirement for B in period 7 is not 11.
	f.	net requirement for F in period 7 is not 24.
	g.	planned order release for D in period 3 is not 12.
	h.	the BOM structure has 2 levels.
	i.	on hand inventory for C in period 5 is 2.
	j.	gross requirement for E in period 6 is 24.

Answer 1

Answer:

a) False, net requirement of B in period 8 is 4.

b) True, planned order releases for F in period 2 is 0.

c) False, on hand inventory for F in period 4 is not 0.

       (On hand inventory for F in period 4 = 20)

d) True, net requirement of E in period 5 is 28.

e) True, gross requirement of B in period 7 is not 11.

     (Gross requirement of B in period 7 = 8)

f) True, net requirement for F in period 7 is not 24

g) True, planned order releases for D in period 3 is not 12.

h) False, the BOM structure does not have 2 levels.

    (The BOM structure has 3 levels.

Level 1= A, Level 2 = B, C, and D, Level 3 = E and F)

i) True, on hand inventory for c in period % is 2.

j) False, gross requirement for E in period 6 is not 24.

  (Gross requirement for E in period 6 = 16)
