What is min max inventory?

How do you find the min/max inventory level?

1. For forced-ordering and continuous review max-min systems, the formula is: Min stock level = lead time stock level + safety stock level.
2. For a standard system, the formula would be: Min stock level = lead time stock level + safety stock level + review period stock level.
