$2.$ Problem StatementI$=\frac{100}{(1-0\mathrm{.}10)}=111$

In a mnaufacturing facility, they run $2$ shifts $(16$ hours per day$)$ to meet the demand of $100$ units. Suppose that each unit takes $25$ minutes to finish. It seems that this production process results in $10\%$ defective parts being re$-$routed to scrap. Now assume that the machine relibaility is $95\%,$ and that parts are produced at $90\%$ of the actual standrad rate.

a$)$ Calculate number of required machines to meet this demand

$F=\frac{SQ}{\text{H}\text{E}\text{R}}=\frac{25\mathrm{.}111}{0\mathrm{.}95*0\mathrm{.}90}=$

b$)$ Now, if the number of shifts become $3$ shifts per day $(\frac{24}{7}$ working mode$),$ how many machines you need to meet a new demand of $130$ units.
