A part structure, lead time $($weeks$),$ and on$-$hand quantities for product A are shown in the

figure below.

a$)$ From the information shown, generate: An indented bill of material $($BOM$)$ for product A $($if

$100$ units is to be produce$).$

b$)$ From the information shown, generate: Net requirements for each part to produce $30$ units of

A in week $8$ and $20$ in week $10.$

$3\mathrm{.}2$ Consider the following requirements for a certain product.

Period $12345678$

Gross requirements $020020050004000400$

Beginning inventory $=500$ units, Setup cost $=$ R$500$ per setup, Lead time $=1$ week

Holding cost $=$ R$3$ per unit per week

Which lot sizing technique will you recommend in order to minimize the total cost? Why?
