Yes, I can definitely help you with that! The formula for calculating minimum and maximum inventory levels is based on the reorder point and the economic order quantity (EOQ). Here are the steps to calculate the minimum and maximum inventory levels:

1. Determine the reorder point: This is the point at which you need to reorder inventory to avoid stockouts. The reorder point is calculated by multiplying the average daily usage by the lead time in days. For example, if you use an average of 10 units per day and the lead time is 5 days, the reorder point would be 50 units (
   Code:

   10 units/day x 5 days

   ).
   
2. Calculate the economic order quantity (EOQ): This is the optimal order quantity that minimizes the total cost of ordering and holding inventory. The formula for EOQ is:
   
   
   Code:

   EOQ = sqrt(2DS/H)

   Whe
   D = annual demand
   S = ordering cost per order
   H = holding cost per unit per year
   
3. Determine the minimum inventory level: The minimum inventory level is the safety stock that you need to hold to avoid stockouts while waiting for the next order to arrive. The formula for minimum inventory level is:
   
   
   Code:

   Minimum inventory level = reorder point - (average daily usage x lead time)

4. Determine the maximum inventory level: The maximum inventory level is the point at which you have enough inventory to meet demand until the next order arrives, without holding excess inventory. The formula for maximum inventory level is:
   
   
   Code:

   Maximum inventory level = EOQ + minimum inventory level

By using these formulas, you can calculate the minimum and maximum inventory levels for your inventory control system. This will help you maintain optimal inventory levels, reduce stockouts, and minimize holding costs. Let me know if you have any questions or need further assistance!
