10/24/2011 4 A company has a chance to reduce their inventory ordering costs by placing larger quantity orders using the price-break order quantity schedule below. What should their optimal order quantity be if this company purchases this single inventory item with an e-mail ordering cost of \$4, a carrying cost rate of 2% of the inventory cost of the item, and an annual demand of 10,000 units? A company has a chance to reduce their inventory ordering costs by placing larger quantity orders using the price-break order quantity schedule below. What should their optimal order quantity be if this company purchases this single inventory item with an e-mail ordering cost of \$4, a carrying cost rate of 2% of the inventory cost of the item, and an annual demand of 10,000 units? Order Quantity(units) Price/unit(\$) 0 to 2,499 \$1.20 2,500 to 3,999 1.00 4,000 or more .98 Price-Break Example
10/24/2011 5 Annual Demand ( D )= 10,000 units Cost to place an order ( S )= \$4 First, plug data into formula for each price-break value of C Carrying cost % of total cost ( i )= 2% Cost per unit ( C ) = \$1.20, \$1.00, \$0.98 Next, determine if the computed Q opt values are feasible or not Price-Break Example Range 0 – 2499 2500 – 3999 4000 + Feasible?

10/24/2011 6 Since the feasible solution occurred in the first price-break, it means that all the other true Q opt values occur at the beginnings of each price-break interval. Why? Since the feasible solution occurred in the first price-break, it means that all the other true Q opt values occur at the beginnings of each price-break interval. Why? 0 1826 2500 4000 Order Quantity Total annual costs Because the total annual cost function is a “u” shaped function Because the total annual cost function is a “u” shaped function Price-Break Example
10/24/2011 7 iC 2 Q + S Q D + DC = TC Next, we plug the true Q opt values into the total cost annual cost function to determine the total cost under each price- break Next, we plug the true Q opt values into the total cost annual cost function to determine the total cost under each price- break Price-Break Example

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

Dana University of Pennsylvania ‘17, Course Hero Intern

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
