# Optimal Solution for Product Cost

This content was STOLEN from BrainMass.com - View the original, and get the already-completed solution here!

I'm looking to understand how to determine the optimization for the following problem.

Part One: What is the optimal solution for this problem?

M&D Chemicals produces two products that are sold as raw materials to companies manufacturing bath soaps and laundry detergents. Based on an analysis of current inventory levels and potential demand for the coming month, M&D's management has specified that the combined production for products A and B must total at least 350 gallons. Separately, a major customer's order for 125 gallons of product A must also be satisfied. Product A requires 2 hours of processing time per gallon while product B requires 1 hour of processing time per gallon, and for the coming month, 600 hours of processing time are available. M&D's objective is to satisfy these requirements at a minimum total production cost. Production costs are \$2 per gallon for product A and \$3 per gallon for product B.

Part Two:
Now assume that the cost per gallon for Product A is increased to \$3 per gallon.

## Optimal Order Quantity in Production

Problem 1
Dulles Electric Company buys 1 million tons of coal annually to burn at its power plant. The company wants to invest in a unit train that will haul coal from the mine to the power house, where it is dumped in a large field. The shipping cost is expected to be \$40 a ton. The cost of capital to Dulles is 10% per annum. The price of coal is \$180 a ton. The cost of processing an order is \$12,500. Find the optimal capacity of the unit train. How often does it make the trip to the mine?

Problem 2
Hull Baking Company uses 250,000 lb of sugar annually in its cakes and pastries. The company can order the sugar in 100 lb bags, at the cost of \$19.50 per bag, delivered. The cost of preparing and sending an order is \$50. The storage and handling costs amount to \$2 per bag per year, based on average inventory. The cost of capital for Hull is 12%. Calculate the optimal size of an order.

Problem 3
Rusk Corporation sells 185,000 gallons of paint annually at several retail outlets. The ordering cost per order is \$75, and its cost of capital is 10%. The storage and handling cost for paint is \$2 per year, based on average inventory. Rusk buys the paint from the manufacturer according to the following price schedule: 1 - 999 gallons at \$11 per gallon, 1000 - 9999 gallons at \$10 per gallon, and 10,000 gallons and over at \$9 per gallon.
(A) Find the optimal order quantity for Rusk.
(B) For this optimal order size, what is the total annual cost of paint?

Problem 4
Seward Company buys 35,000 lb of flour annually. The cost of placing an order is estimated to be \$35, and its cost of capital is 12%. The storage and handling costs are estimated to be 2 cents per lb annually, at the average inventory level. The price of flour is as follows: up to a 1000 lbs at 12¢ per lb, 1,000 to 4999 lbs at 11¢ per lb, and 5,000 lbs and over at 10¢ per lb. Find the optimal order quantity of flour for Seward.
