Solved: Can someone explain to me how do we define what week to place a number for the required

Can someone explain to me how do we define what week to place a number for the required dates?

I understand part A but the other parts seem confusing.

For example, why do part B and C both have a required date in week 7?

Why do part E and D both have a required date in week 6?

Expert Answer

Note that as per the product structure,

two(2) units of B are fitted in one(1) unit of A
& three(3) units of C are fitted in one(1) unit of A.

Since B. and C are just at the lower hierarchy of ‘A’ in the product structure, the week when the order release of A happens, the required date of B and C happens.

So, since the order release of A happens in week 7, the required date of B, and C is in the same week (i.e. week 7). The numbers are as per the units required i.e. No. of B = 2 x No. of A = 2 x 50 = 100 and No. of C=3 x 50 = 150.

E, and D are more complicated. But the logic is the same as above.

Consider ‘E’ first.

Two(2) units of E are fitted in one(1) unit of B

Since E is just at the lower hierarchy of B in the product structure, the week when the order release of B happens, the required date of E happens.

So, since the order release of B happens in week 5, the required date of E is in the same week (i.e. week 5). The numbers are as per the units required i.e. No. of E = 2 x No. of B = 2 x 100 = 200

So, for making ‘B’ only, we need 200 units of E in week 5 ————————–1

Two(2) units of E are fitted in one(1) unit of C

Since E is just at the lower hierarchy of C in the product structure, the week when the order release of C happens, the required date of E happens.

So, since the order release of C happens in week 6, the required date of E is in the same week (i.e. week 6). The numbers are as per the units required i.e. No. of E = 2 x No. of C = 2 x 150 = 300

So, for making ‘C’ only, we need 300 units of E in week 6 ————————– 2

Combine 1 and 2 to get the overall requirement of E i.e. 200 in week 5 and 300 in week 6

——————————–

Consider ‘D’ now

Two(2) units of D are fitted in one(1) unit of B

Since D is just at the lower hierarchy of B in the product structure, the week when the order release of B happens, the required date of D happens.

So, since the order release of B happens in week 5, the required date of D is in the same week (i.e. week 5). The numbers are as per the units required i.e. No. of D = 2 x No. of B = 2 x 100 = 200

So, for making ‘B’ only, we need 200 units of D in week 5 ————————–3

Two(2) units of D are fitted in one(1) unit of F

Since D is just at the lower hierarchy of F in the product structure, the week when the order release of F happens, the required date of D happens.

So, since the order release of F happens in week 3, the required date of D is in the same week (i.e. week 3). The numbers are as per the units required i.e. No. of D = 2 x No. of F = 2 x 300 = 600

So, for making ‘F’ only, we need 600 units of D in week 3 ————————–4

Combine 3 and 4 to get the overall requirement of D i.e. 200 in week 5 and 600 in week 3
