XYZ Foods is considering producing a new candy, Tira-Tira. XYZ has spent two years and P450,000 developing this product. XYZ has also test marketed Tira-Tira, spending P100,000 to conduct consumer surveys and tests of the product in 25 states. Based on previous candy products and the results in the test marketing, management believes consumers will buy 4 million packages each year for ten years at 50 cents per package. Equipment to produce Tira-Tira will cost XYZ P1,000,000, and P300,000 of additional net working capital will be required to support Tira-Tira sales. XYZ expects production costs to average 60% of Tira-Tira’s net revenues, with overhead and sales expenses totaling P525,000 per year. The equipment has a life of ten years, after which time it will have no salvage value. Working capital is assumed to be fully recovered at the end of ten years. Depreciation is straight-line and XYZ’s tax rate is 45%. The required rate of return for projects of similar risk is 10%. A. What…
In a cold storage plant, it is desired to determine whether to use insulation two inches thick or three inches in insulating the walls of the cold storage warehouse. Heat absorbed through the walls without insulation would cost P96.00 per year per square meter. Two-inch insulation will cost P30.40 per square meter and will cut out 89% of the loss. Three-inch insulation will cut out92% of the loss and will cost P65.00 per square meter. Using life of 15 years for the insulation with no salvage value and a minimum attractive return of 8%, what thickness of insulation should be used?
A computer manufacturer purchases microchips from a world-class supplier. Th e buyer has a lot tolerance proportion defective of 10 parts in 5000, with a consumer’s risk of 15 percent. If the computer manufacturer decides to sample 2000 of the microchips received in each shipment, what acceptance number, c, would it want?

ABC Pharmaceutical Company is planning to produce exactly 40 kilograms of a mixture of new low-price generic multivitamin in which the basic ingredients, Ascorbic Acid and Thiamine, cost P 8.00 per kilo and P 15.00 per kilo, respectively. The present inventory of the company’s raw materials shows that they only have 12 kilos of Ascorbic Acid. The inventory level of the slow-moving Thiamine is more than sufficient so they want to dispose at least 10 kilos of it. Is the problem a maximization or a minimization one?
Duke Energy reported that the cost of electricity for an efficient home in a particular neighborhood of Cincinnati, Ohio, was $104 per month. A researcher believes that the cost of electricity for a comparable neighborhood in Chicago, Illinois, is higher. A sample of homes in this Chicago neighborhood will be taken and the sample mean monthly cost of electricity will be used to test the following null and alternative hypotheses. Assume the sample data lead to rejection of the null hypothesis. What would be your conclusion about the cost of electricity in the Chicago neighborhood? What is the Type I error in this situation? What are the consequences of making this error? What is the Type II error in this situation? What are the consequences of making this error?
Panguitch Company manufactures a component for tablet computers. Weight and durability of the component are the two most important quality characteristics for the tablet manufacturers. With respect to the weight dimension, the component has a target value of 100 grams. Specification limits are 100 grams, plus or minus five grams. Products produced at the lower specification limit of 95 grams lose 20. A sample of five units produced the following weight measures: During the first quarter, 100,000 units were produced. Required: 1. Calculate the loss for each unit. Calculate the average loss for the sample of five. 2. Using the average loss, calculate the hidden quality costs for the first quarter. 3. Durability is another important quality characteristic. The target value is 20,000 hours of operation before failure. The lower specification limit set by engineering and marketing is 19,000 hours. They agreed that there should be no upper specification limit. They also noted that there is a 750 loss at the lower specification limit. Explain why there would be no upper specification limit. Use the lower limit and the left half of the Taguchi quadratic loss function to estimate the loss for components with the following lives: 6,500 hours, 11,000 hours, and 15,500 hours. What does this reveal about the importance of durability?
A mechanical engineer is considering two types of pressure sensors for the low-pressure steam lines in several of the company plants. Piezoresistive sensors use the change in conductivity of semiconductors to measure the pressure. Fiber optic sensors use the properties of fiber optic interferometers to sense nanometer scale displacement of membranes. The costs for each system are shown below. Which should be selected based on a present worth comparison at an interest rate of 1% per month?
A manufacturer of thermostats uses a kanban system tocontrol the fl ow of materials. Th e packaging center processes 10thermostats an hour and receives completed thermostats every 30minutes. Containers hold 5 thermostats each.(a) How many kanbans are needed for the packaging center?(b) If management decides to keep two thermostats as safetystock, how many kanbans will be needed?
In a bio-based material recycling company, the operation managers are considering a twin-screw extruder with a price of 12,000 OMR and another 2,000 OMR will be spent for shipping and installation of the extruder. The estimated net income generated from this machine is 3,500 OMR per year. The extruder will be used for 5 years, and then it will be sold for an estimated market value of 2,500 OMR. The extruder MARCS property class is 5 years. If the effective income tax rate (t) is 40% and the after-tax MARR is 10%. (a) What is the after-tax IRR for this project? (use trial and error procedure and GDS) (b) Should this extruder be purchased by the company?
A store makes 200 cherry cheesecakes at a cost of $2.35 each. If a spoilage rate of 5% is anticipated, at what price should the cakes be sold to achieve a 40% markup based on cost
Your first job as an engineer is to purchase a new rotary vacuum-drum filter with a capacity of 1100 ft-. Your company purchased a similar filter eight years ago with a capacity of 700 ft- for $26,000. After checking the literature, you determine the cost index was 429 eight years ago and is 548 today. If the power-sizing exponent for this type of equipment is 0.52, estimate the cost of the new filter.
