Find out the given stock levels for Danex Holdings as:
i. Minimum stock level
ii. Maximum stock level
iii. Re-order level
Solution
i) Re-order level
= Maximum consumption X maximum reorder period
= 450 units X 5 weeks
= 2,250 units
ii) Maximum stock level
= reorder level + reorder quantity-(Minimum consumption X minimum reorder period)
= 2250 + 1800 - (150 X3) = 4050 - 450 = 3600 units
iii) Minimum stock level
= Reorder level - (Normal consumption X normal reorder period)
= 2,250 - (300 X 4) = 2250 - 1200 = 1050 units
