The following $5$ months of demand are:

Month $12345$

Demand $2050401015$

The fixed order cost is $$50.$ The unit cost is $$5$ and the monthly interest rate is $0\mathrm{.}1.$ At month $0,$ the

inventory dropped to zero, and we need to plan the orders to place for the next $5$ months.

Replenishments occur at the beginning of each month. Create an order schedule using the

following policies and calculate the total relevant cost. Which policy provides the best schedule to

follow?

$1)$ EOQ with average demand $($closest to EOQ$)$

$2)$ Period Order Quantity

$3)$ Silver$-$Meal
