North Platt Machinery Company manufactures a shaft that must fit inside a sleeve. The firm has just received an order of 50,000 units from Southernstar Exploration Company for $80 per unit. North Platt can manufacture the shaft at $50 per unit. Southernstar desires the diameter of the shaft to be 1.275 cm. The diameter of the shaft must not be less than 1.25 cm in order to fit properly inside the sleeve. To be able to insert the shaft into a sleeve without the use of force, the diameter cannot be larger than 1.30 cm. A defective shaft is discarded and a replacement has to be shipped via express freight to locations around the world. North Platt estimates that the average cost of handling and shipping a replacement shaft will be approximately $70. Shown below are the diameters from a sample of 80 shafts manufactured during a trial run: Diameter Number of Units Diameter 1.232 1 1.273 Number of Units 6 Number of Diameter Units 1.292 2 1.240 2 1.274 7 1.293 1 1.250 3 1.275 18 1.294 4 1.258 2 1.276 8 1.298 2 1.262 2 1.277 5 1.300 2 1.270 3 1.280 2 1.304 1 1.272 6 1.288 2 1.320 1 Required: Set up an Excel spreadsheet that uses a Taguchi quality loss function to determine: 1. The expected loss (total quality cost) per unit, E[L(x)], from this process. (Do not round intermediate calculations. Round your answer to 2 decimal places.) 2. The diameter tolerance that should be set for the manufacture of the shaft. (Do not round intermediate calculations. Round your answer to 4 decimal places.) Answer is complete but not entirely correct. 1. Expected loss $ 2. Tolerance 11.98 X 0.0250 cm

In connection with surfacing a new highway, a contractor has a choice of two sites on which to set up the mixing plant equipment. The contractor estimates that it will cost P51.75 per cubic meter per kilometer to haul the asphalt paving material from the mixing plant to the job site. If site B is selected, there will be an added charge of P600 per day for a flagman and it needs 2 flagman. The job requires 50,000 cubic meters of mixed asphalt paving material. It is estimated that four months (17 weeks of five working days per week) will be required for the job. Cost Factors Site A Site B Average hauling distance 6 km 4.3 km Monthly rental of site P45,000 P225,000 Cost to setup and remove equipment P675,000 P1,125,000 Hauling expense P51.75/ Cu.m/km P51.75/ Cu.m/km a) Compare the two sites in terms of their fixed, variable, and total costs. b) For the selected site, how much profit can be made if it is paid P362.25 per cubic meter delivered to the job site?

Shrewsbury Technologies, which manufactures high-technology instruments for spacecraft, is considering the sale of a navigational unit to a private company that wishes to launch its own communications satellite. The company plans to purchase 8 units, although it would also consider buying 16 units. Shrewsbury has started a chart relating labor time required to units produced: Unit Produced (X) Time Required to Produce the Xth Unit 1 18,000 hours 2 14,400 hours 4 11,520 hours 8 ? 16 ? Questions: Compute the labor time required to produce 8 and 16 units. Assume that labor time costs $153 per hour. Compare the cost of producing the 1st unit to the cost of producing the 16th unit. What is the percentage of the cost of the 16th unit to the cost of the 1st unit?

Haver Company currently pays an outside supplier $15 per unit for a part for one of its products. Haver is considering two alternative methods of making the part. Method 1 for making the part would require direct materials of $5 per unit, direct labor of $8 per unit, and ncremental overhead of $3 per unit. Method 2 for making the part would require direct materials of $5 per unit, direct labor of $2 per unit, and incremental overhead of $7 per unit. Required: 1. Compute the cost per unit for each alternative method of making the part. 2. Should Haver make or buy the part? If Haver makes the part, which production method should it use?

Alderon Enterprises is evaluating a special order it has received for a ceramic fixture to be used in aircraft engines.  Alderon has recently been operating at less than full capacity, so the firm's management will accept the order if the price offered exceeds the costs that will be incurred in producing it.  You have been asked for advice on how to determine the cost of two raw materials that would be required to produce the order. A) The special order will require 800 gallons of Endor, a highly perishable material that is purchased as needed.  Alderon currently has 1,200 gallons of Endor on hand, since the material is used in virtually all of the company's products.  The last time endor was purchased, Alderon paid $5.00 per gallon.  However, the average price paid for the endor in stock was only $4.75.  The market price for the Endor is quite volatile, with the current price at $5.50.  If the special order is accepted, Alderon will have to place a new order next week to replace the…

Algonac Moldings produces a product made from a metal alloy. Two suppliers, Liebold Metal and Cecil Distributors, supply the alloy. Neither supplier can meet Algonac's typical demand, because of capacity constraints. The material from Liebold is less expensive to buy but more difficult to use, resulting in greater waste. The metal alloy is highly toxic and any waste requires costly handling to avoid environmental accidents. Last year the cost of handling the waste totaled $1,200,000. Additional data from last year’s operations are shown as follows:   Liebold Metals Cecil Distributors Amount of material purchased (tons) 64.8 115.2 Amount of waste (tons) 9.0 11.0 Cost of purchases $ 1,488,000 $ 3,312,000 Required: Allocate the cost of the waste handling to the two suppliers based on: Amount of material purchased. Amount of waste. Cost of material purchased. Amount of material purchased. Note: Do not round intermediate calculations. A.)…
