SELF-CHECK
With demand 20 units/day, lead time 5 days and buffer 30 units, what is the reorder point?

REFERENCE REASONING
20×5+30=130 units. If lead time becomes 7 days while the buffer stays 30, the modeled point becomes 170 units.

This is a reasoning reference for the supplied fictional case, not an executed app or tested cloud deployment. Alternative approaches are valid when supported by stated assumptions and evidence.
