Race One Motors is an Indonesian car manufacturer. At its largest manufacturing facility, in Jakarta, the company produces subcomponents at a rate of 300
per day, and it uses these subcomponents at a rate of 12,500 per year (of 250 working days). Holding costs are $2.00 per item per year, and ordering costs are
$30.00 per order.

a) What is the economic production quantity? units (round your response to two decimal places).

All answers are wrong because of a mistake in (A). (https://slideplayer.com/slide/4167360/13/images/53/EPQ+Formula+d+%3D+daily+demand+in+units%2C.jpg) \(EPQ=\frac{\sqrt{2\cdot annual\ demand\ \cdot \ setup}}{H\left(1-\frac{d}{p}\right)}\) Answer is 670.82

No of Production runs per year =  Annual Demand / EPQ

No of Production runs per year =  12,500 per year / 670.82 = 18.63

Answering the others now...

Maximum Inventory Level = P ( Q / P ) -d ( Q / P )

P = production rate = 300
d= Daily Demand Rate = 12500 / 250 = 50 units per day
Q = P * t (total days) = 250 * 300 = 75000

Maximum Inventory Level = 300 ( 75000 / 300 ) - 50 ( 75000 / 300 ) = 75000 - 12500 = 62500
