PLEASE DO #$13-21$ & $#$13-22$

#$13-21$: Dumgor Appliance Center sells and services several brands of major appliances. Past sales for a particular model of refrigerator have resulted in the following probability distribution for demand:

$-$The lead time, in weeks, is described by the following distribution:

$-$Based on cost considerations as well as storage space, the company has decided to order $10$ of these each time an order is placed. The holding cost is $$1$ per week for each unit that is left in inventory at the end of the week. The stockout cost has been set at $$40$ per stockout. The company has decided to place an order whenever there are only $2$ refrigerators left at the end of the week. Simulate $10$ weeks of operation for Dumoor. Appliance, assuming there are currently $5$ units in inventory. Determine what the weekly stockout cost and weekly holding cost would be for the problem.

Use the table experiment setup below for both simulations.

RN$1$ is the first column from Table $13\mathrm{.}4,$ p$.467$

$R{N}_2$:$06,63,57,02,94,52,69,33,32,$ and $30.$

Totals End Inv Lost Sales

The total stock out cost total # of lost sales$)($$$40)$

The total holding cost $=($total # of End Inv$)($$$1)$

For #$13-22$ repeat the same simulation with the same random numbers but reorder point is $4$ refrigerators instead of $2\mathrm{.}1$
