$[$Reorder Point for Variable Demand and Constant Lead Time$]$

$[2$ points$]$ Suppose that the average demand is $18$ units per week with a standard deviation

of $5$ units. The lead time is constant at $2$ weeks. Determine the safety stock and reorder

point if management wants a $90$ percent cycle$-$service level.

$($Hint: choose a z score corresponding to a CSL that is the closest to $90\%$;

when safety stock is not an integer, think about whether the result should be rounded

up or rounded down. To be practical, both safety stock and reorder point need to be

integers.$)$
