Given are following details :
Annual demand = D = 1500 / month x 12 months = 18000
Ordering cost = Co = $75
Annual unit holding cost = Ch = $3.75 per box
Optimal order quantity
= Square root ( 2 x Co x D / Ch )
= Square root ( 2 x 75 x 1500 / 3.75 )
= 244.94 ( 245 rounded to nearest whole number )
OPTIMAL ORDER QUANTITY = 245 |
Number of orders per year
= Annual demand / Optimal order quantity
= 18000/ 245
= 73.47
NUMBER OF ORDERS PER YEAR = 73.47 |
Reorder point
= Average daily demand x Lead time
= annual demand / Number of days in a year x Lead time ( days )
= 18000 / 300 x 7
= 60 x 7
= 420 units
REORDER PIINT = 420 UNITS |
