Question 1

In a price break model of lot sizing,to find the lowest-cost order quantity,it is sometimes necessary to calculate the economic order quantity for each possible price and to check to see whether the lowest cost quantity is feasible.

Accepted Answer

Step 1.Sort the prices from lowest to highest and then,beginning with the lowest price,calculate the economic order quantity for each price level until a feasible economic order quantity is found.By feasible,we mean that the price is in the correct corresponding range.
Step 2.If the first feasible economic order quantity is for the lowest price,this quantity is best and you are finished.Otherwise,calculate the total cost for the first feasible economic order quantity (you did these from lowest to highest price)and also calculate the total cost at each price break lower than the price associated with the first feasible economic order quantity.This is the lowest order quantity at which you can take advantage of the price break.The optimal Q is the one with the lowest cost.

Question 2
