a factory has a production plan calling for 20,000 products/year. the cost to process a single work order is $50 and the cost to hold one unit of one product in stock for one year is $5. the production rate is 100 units/day and the usage rate is 60 unit/day.
1. write the equation for epq and label the variable.
2. compute the factory EPQ
3. What is the maximun level of finished goods inventory?
Following are the set of data provided :
Annual demand = D = 20,000 units
Daily demand ( usage ) rate = d = 60 units/ day
Daily production rate = p = 100 units/ day
Ordering cost = Co = $50
Holding cost per unit per year = Ch = $5
Equation for EPQ
= Square root ( 2 x Co x D / Ch x ( 1 – d/p))
Value of EPQ
= Square root ( 2 x 50 x 20,000/5 x ( 1 – 60/100) )
= Square root ( 2 x 50 x 20,000 / 5 x 0.4)
= Square root ( 1000000)
= 1000
EPQ = 1000 |
Maximum level of finished goods inventory
= EPQ x ( 1 – d/p)
= 1000 x ( 1 – 60/100)
= 1000 x 0.4
= 400
MAXIMUM LEVEL OF FINISHED GOODS INVENTORY = 400 UNITS |
