For a particular process, originally each 200 units of product manufactured yielded 180 conforming units, 9 units that must be scrapped, and the remaining units that must be reprocessed. Each scrapped unit results in a $30 loss and each reprocessed unit requires an extra 0.45 hours of processing time. The resource time of producing the original 200 units is 30 hours. As a result of a quality improvement program that was recently introduced, for each 200 units manufactured, the process now yields 190 conforming units, 4 unit to be scrapped, and the remaining units that must be reprocessed. Calculate the productivity (in units per hour) for the original process

Suppose that GLC earns a 2000 profit each time a person buys a car. We want to determine how the expected profit earned from a customer depends on the quality of GLCs cars. We assume a typical customer will purchase 10 cars during her lifetime. She will purchase a car now (year 1) and then purchase a car every five yearsduring year 6, year 11, and so on. For simplicity, we assume that Hundo is GLCs only competitor. We also assume that if the consumer is satisfied with the car she purchases, she will buy her next car from the same company, but if she is not satisfied, she will buy her next car from the other company. Hundo produces cars that satisfy 80% of its customers. Currently, GLC produces cars that also satisfy 80% of its customers. Consider a customer whose first car is a GLC car. If profits are discounted at 10% annually, use simulation to estimate the value of this customer to GLC. Also estimate the value of a customer to GLC if it can raise its customer satisfaction rating to 85%, to 90%, or to 95%. You can interpret the satisfaction value as the probability that a customer will not switch companies.
The American National Bus Lines is proud of its 8-week bus driver training program that it conducts for all its drivers. Each 8-week training program costs the company $ 25000 for instructors, equipment and so on and is independent of the number of new drivers in the class as long as the class size remains less than or equal to 35. The training program must provide the company with 7 new fully trained drivers per month. After completing the training program, new drivers are paid $1800 per month but do not work until a full-time position is open. The company views the $1800 as holding cost necessary to maintain a supply of newly trained drivers available for immediate service. Viewing new drivers as inventory –type units, how large should the training classes be in order to minimize the total annual training and new driver idle-time costs? How many training classes should the company hold each year? What is the total annual cost of your recommendation?
Sunblessed Juice Company sells bags oforanges and cartons of orange juice.Sunblessed grades oranges on a scale of 1(poor) to 10 (excellent). At present,-Sunblessed has 100,000 pounds of grade 9oranges and 120,000 pounds of grade 6 oranges on hand. The average quality of oranges sold in bags must be at least 7, and the average quality of the oranges used to produce orange juice must be at least 8. Each pound of oranges that is used for juice yields a revenue of $1.50 and incurs a variable cost (consisting of labor costs,variable overhead costs, inventory costs,and so on) of $1.05.

You are working to model your production function and you are interested in the equation of the line tangent to the production function at a specific level of production. You know that the equation of the tangent line will be first derivative of the production function. Given this information, Previously, a consultant had estimated that your production function could be estimated as f(x) = -1,000 + 26 hours - 0.2 hours^2 Given that you firm is planning to use 97 hours in the production process, what is the value of the equation of the tangent line at 97?
Creative sports design (CSD) manufactures a standard size racket and an over sized racket. The firm's rackets are extremely light due to the use of a magnesium- graphite alloy that was invented by the firm's founder. Each standard size racket uses 0.125 kilograms of the alloy and each oversize racket uses 0.4 kilograms; over the next two week production period only 80 kilograms of the alloy are available. Each standard size racket uses 10 min. of manufacturing timeand each oversize racket uses 12 min. The profit contributions are $10 for each standard size racket and $15 for each oversized racket, and 40 hours of manufacturing time are available each week. Managment specified that at least 20% of the total production must3 be the standard size racket. How many rackets of each type should CSD manufacture over the next 2 weeks to maximize the total profit contributions? Assume that because of the unique nature of their products, CSD can sell as many rackets as they can produce?
The seasonal yield of olives greatly increases by a process of branch pruning instead of olives by normal process. The yield of 1 barrel of olives by pruning requires 5 hours of labor and 1 acre of land. The production of a barrel of olives by the normal process requires only 2 labor hours but takes 2 acres of land. An olive grower has 250 hours of labor available and a total of 150 acres for growing. A barrel of olives produced on pruned trees sells for $20, whereas a barrel of regular olives has a market price of $30. The grower has determined that because of uncertain demand, no more than 40 barrels of pruned olives should be produced. The best combination of barrels of pruned and regular olives in order to earn maximum profit X1(barrels of pruned) and X2( barrels of regular olives) One of the constraints of the problem is Select one: 2X1+5X2<=250 30X1+20X2<=250 2X1+2X2<=250 5X1+2X2<=250 5X1+2X2>=250
The Electrocomp Corporation manufactures two electrical products: air conditioners and large fans. The assembly process for each is similar in that both require a certain amount of wiring and drilling. Each air conditioner takes 3 hours of wiring and 2 hours of drilling. Each fan must go through 2 hours of wiring and 1 hour of drilling. During the next production period, 240 hours of wiring time are available and up to 140 hours of drilling time maybe used. Each air conditioner sold yields a profit of $25. Each fan assembled may be sold for a $15 profit. Formulate and solve this LP production mix situation to find the best combination of air conditioners and fans that yields the highest profit. Use the corner point graphical approach
Duluth Electronics makes two types of scooters: Falcon and Hawk. The Falcon model has a lighter engine and a smaller frame to make novice riders easier to balance. The Hawk is a little bigger and uses a heavier engine. Falcon requires 6 hours of manufacturing time and Hawk takes only 3 hours. Duluth's main plant in Kentucky has 2,100 hours of engine manufacturing time available. Duluth's vendors have the ability to supply as many Falcon frames as needed, but they only provide 280 Hawk frames. Falcon requires 2 hours of testing and 2.5 hours for Hawk. There are only 1,000 hours available for testing. The finance department estimates that the Falcon model contributes a profit of $2,400 and the Hawk $1,800.
