Apply $3$ lot$-$sizing rules $($FOQ$,$ POQ and L$4$L$)$ to the data given in the problem.

Estimate the holding cost

Estimate the ordering cost

Use EOQ to determine FOQ and POQ

This part, if correct, is worth $8$ out of $10$ points

Apply $2$ more lot$-$sizing rules not covered in class. You can try part$-$period balancing and Wagner$-$Whitin rules. For each correctly applied extra lot$-$sizing rule you will receive $1$ point each.

Submit your results including the MRP explosion $($inventory records$)$ and the total cost for each rule. The total cost is computed using the POH as inventory and the number of POReceipts as the number of orders$/$setups$.$

Use a table showing the lot$-$sizing rule versus the inventory carrying cost, the setup cost and the total inventory cost.
