Question $1(3$ Parts$)$

Part A$.$ Develop the inventory profile of the EOQ model for $13$ days where lead time is $2$ days, usage rate $80$ units$/$day and EOQ is $480$ units. What is ROP and inventory on day $13?$

Part B$.$ Draw the EPQ diagram with a run time of $5$ days and a cycle time is $8$ days. Find the maximum inventory if the production rate is $80$ units and usage rate is $50$ units.

Part C$..$ How much can you save if you use EOQ instead of any other quantity? Explain it with the diagram. Assume all the necessary values.
