the gulf coast foundry is developing a long range strategic plan for buying scarp metal for its foundry oprations the foundry can buy scrap metal in unlimited quantities from two sources, Atlanta(A) and Birmingham (B), and it receives the scrap daily in railroad cars. the scrap is melted down, and lead lead and copper are extracted for use in the foundry processes each railroad car of scrap from source A yields 1 ton of copper and 1 ton of lead and cost $10,000.
each railroad car of scrap from source B yields 1 ton of copper and 2 tons of lead and costs $15,000, if the foundry needs at least 2 and a half tons of copper and at least 4 tons of lead per day for the foreseeable future, how many railroad cars of scrap should be ( purchased per day from source A and source B to minimize the long range scrap metal cost?
The Aggies will host Tech in this year’s homecoming football game. Based on advance ticket sales, the athletic department has forecast hot dog sales as shown in the following table. The school buys premium hot dogs for $1.50 and sells them during the game at $3.00 each. Hot dogs left over after the game will be sold for $0.50 each to the Aggie student cafeteria, where they will be used in making hotdog casserole.Sales Quantity Probability2,000 0.103,000 0.304,000 0.305,000 0.206,000 0.10Use a payoff matrix to determine the number of hot dogs to buy for the game.

Yearly Demand in 000's: Year 1, Year 2, Year 3, Year 4:
Bronze 90: 7, 8, 9, 10
Bronze 190: 3, 4, 5, 6
Bronze 360: 11, 12, 15, 18
The machines needed for the bronze sprinklers require two operators, and can produce up to 12,000 sprinklers. Three bronze machines and only one injection molding machine are available.
What are the capacity requirements for the next four years, assume that there is no learning?

- Problem 8-21 (Algorithmic) Round Tree Manor is a hotel that provides two types of rooms with three rental classes: Super Saver, Deluxe, and Business. The profit per night for each type of room and rental class is as follows: Rental Class Room Super Saver Deluxe Business Type I $30 $35 — Type II $20 $30 $40 Type I rooms do not have wireless Internet access and are not available for the Business rental class. Round Tree's management makes a forecast of the demand by rental class for each night in the future. A linear programming model developed to maximize profit is used to determine how many reservations to accept for each rental class. The demand forecast for a particular night is 130 rentals in the Super Saver class, 60 rentals in the Deluxe class, and 50 rentals in the Business class. Round Tree has 100 Type I rooms and 120 Type II rooms. Use linear programming to determine how many reservations to accept in each rental class and how the reservations should be…arrow_forwardThe Scottville "Mill" produces five different fabrics. Each fabric can be woven on one or more of the mill's 38 looms. The sales department has forecast demand for the next month. The demand data are shown in Table 1.0 below along with data on the selling price per yard, variable cost per yard, and purchase price per yard. The mill operates 24 hours a day and is scheduled for 30 days during the coming month. The Mill has two types of looms: dobbie and regular. The dobbie looms are more versatile and can be used for all five fabrics. The regular looms can produce only three of the fabrics. The Mill has a total of 38 looms: 8 are dobbie and 30 are regular. The rate of production for each fabric on each type of loom is given in Table 1.1. The time to change over from producing one fabric to another is negligible and does not have to be considered. The Scottsville Mill satisfies all demand with either its own fabric or fabric purchased from another mill.

You are forecasting demand of 5000 coats in October, 8000 coats in November, 8000 coats in December, 12000 coats in January, 12000 coats in February and 9000 coats in March. You want to manufacture these coats at the lowest cost possible during your production window (October-March). The first decision you need to make is how many people to hire. Each employee will cost $2500 a month. You don’t want to hire or fire any employees mid-season in order to minimize disruptions in your factory floor. You can have employees idle if there isn’t sufficient work for them to do. Employees still need to be paid even if they are idle.

- The Gotham City News is moving to a paywall subscription service rather than a free news website with unlimited access. If Subscribers would like to access more than ten articles per month, they will need to pay a monthly subscription fee of $22. However, if they are also weekly subscribers of the print edition of the newspaper, they receive a 60% discount on the on-line subscription rate. The monthly rate for the print edition of the newspaper is $29. Based on the market research, the Times believes that 24% of the households that order the print edition will also order the website subscription. While there are basically no variable costs to the website version, the print edition does cost $23 per month to print and dekiver to households. Market research indicates that the average length a current print edition subscriber will continue subscribing is only 16 months if they choose to also purchase the on-line subscription.
