Please provide the methodolofy to solve. The flow structure is : from material supplier to Zamsung FLash drive manufacturing and then FG inventory at Zamsung after $6$ days. Then it goes to Zenovo Manufacturing and then to Retailers

$($c$)$ Inventory level of Flash drive Finished Goods $($FG$)$ at Zamsung is reviewed at an

interval of once per week $($week $=7$ days$).$ Immediately after each review, a quantity

is ordered by the Zamsung Inventory controller to raise the total of in$-$hand and on$-$

order inventory of Flash drives in FG to be $434$ units $($i$.$e$.$ Base$-$stock is $434).$ When

Inventory controller places an order to the Zamsung plant, it delivers the requested

quantity of XRiE Flash drive units to the FG after $6$ days. Assume the daily demand

for XRiE Flash drive is stable and normally distributed with a mean of $31$ units and

standard deviation is $4\mathrm{.}5.$ Assume both the Zamsung plant and the Zenovo plant work

$24$ hours per day, $7$ days per week throughout the year. $($Normal distribution tables can

be found in appendix $1$ of this paper$)$

$(1)$ Compute the service level in terms of the coverage probability $($Type $1$ service

level$)$ provided to Zenovo using the inventory control policy described above.

$(4$ marks$)$

$($ii$)$ Compute the average number of stock$-$outs at the FG inventory per year,

assuming $52$ weeks of operation per year.

$(4$ marks$)$

$($iii$)$ Compute the average inventory level of the XR$\mathrm{.}1$E Flash drive units in $FG$

inventory under this policy.

$(1$ mark$)$

$($iv$)$ Zamsung decided to continuously review the inventory of XRiE Flash drive

units in the $FG$ and use continuous review $Q-R$ inventory policy with

Economic Order Quantity $($EOQ$)$ as the $Q$ value. Assume the daily demand

and standard deviation of demand remain as specified in this question and both

the Zamsung and the Zenovo work $24$ hours per day, $7$ days per week

throughout the year.

The order cost $($including transport$)$ is $$20$ per order placed and holding cost

per year is $$45\mathrm{.}26$ per unit. What will be their order quantity based on their

revised Q$-$R policy?

$(1$ mark$)$

$($v$)$ Zamsung manufacturing wanted to provide a coverage probability $($Type $1$

gervice level$)$ of $99\mathrm{.}5\%$ for XRiE Flash Drives. At what level of inventory in

FG should they place a new order in each cycle to provide such customer

service?

$(4$ marks$)$

$($vi$)$ Given that approximate order cycle in days is determined by $Q($units$)\frac{?}{()}$

$($units$/$day$),$ how many stock$-$outs might they expect per year under this revised

policy?

$(4$ marks$)$

Note: Question $1$ continues on page $3.$

$($vii$)$ What will be the average inventory level of XRiE Zamsung Flash Drives at

FG inventory with this revised inventory control system?

$(2$ marks$)$

$($viii$)$ If the XRiE Flash drive is a high$-$end product, which policy would you

recommend and why? Use your computed measures in the earlier sections of

each policy to justify your answer.
