At the beginning of each week, a machine is in one of four conditions: 1 = excellent; 2 = good; 3 = average; 4 = bad. The weekly revenue earned by a machine in state 1, 2, 3, or 4 is 100, 90, 50, or 10, respectively. After observing the condition of the machine at the beginning of the week, the company has the option, for a cost of 200, of instantaneously replacing the machine with an excellent machine. The quality of the machine deteriorates over time, as shown in the file P10 41.xlsx. Four maintenance policies are under consideration: Policy 1: Never replace a machine. Policy 2: Immediately replace a bad machine. Policy 3: Immediately replace a bad or average machine. Policy 4: Immediately replace a bad, average, or good machine. Simulate each of these policies for 50 weeks (using at least 250 iterations each) to determine the policy that maximizes expected weekly profit. Assume that the machine at the beginning of week 1 is excellent.

Problem 6-2 (Algo) Rachel loves to bake cookies, but she has an old oven that has trouble maintaining a constant temperature. If the acceptable temperature range for making the cookies is 350 plus or minus 10 degrees, what is the allowable standard deviation in the temperature of her oven in order to achieve a Six Sigma level of quality? Note: Round your answer to 3 decimal places. Standard deviation degrees
42. A large national producer of appliances has traced customer experience with a popular toaster oven. A survey of 5,000 customers who purchased the oven early in 2000 has revealed the following: nd ity Number of Year Breakdowns 2000 188 2001 58 2002 63 2003 72 2004 54 2005 71 a. Using these data, estimate på = the probability that a toaster oven fails in its kth year of operation, for k = 1, . . . , 6. b. What is the likelihood that a toaster oven will last at least six years without failure based on these data? c. The discrete failure rate function has the form r; = Pr/Rp–1, where Rỵ is the prob- ability that a unit survives through period k. Determine the failure rate function for the first five years of operation from the given data. d. Suppose that you purchased a toaster oven at the beginning of 2004 and it is still operating at the end of 2007. If the reliability has not changed appreciably from 2000 to 2007, use the results of part (c) to obtain the probability that it will…
You are a food specialist in a company that specializes inrefrigerated delicacies, and one of your brands requires beingmaintained at a temperature of 5°C. You determine averagewater activity (aw) at this temperature to be 0.2. One day, you are informed that the cooling systems onone of the delivery trucks carrying your company’s productsmalfunctioned while en route to its destination and it would notbe fixed until the next delivery. The driver has informed you thatthe temperature in the delivery bay of the truck is averaging55°C. You estimate a heat of sorption (Q) of 19 kJ/mol. Calculate the water activity of the brand at this elevatedtemperature and comment on it’s integrity. Should the deliverystill push through? Or should the products be recalled anddisposed
1. Three hundred identical cathode ray tubes (CRTS) placed into service simultaneously on January 1, 1976, experienced the following numbers of failures through December 31, 1988: 1983 Year Number of failures 1984 1985 1986 1987 1988 13 19 16 34 21 38 Assume that there were no failures before 1983. a. Based on these data, estimate the cumulative distribution function (CDF) of a CRT chosen at random. Using the results of part (a), estimate the probability that a CRT chosen at random 13.1 Reliability of a Single Component 753 b. Lasts more than 5 years. c. Lasts more than 10 years. d. Lasts more than 12 years. e. That has survived for 10 years fails in the 11th year of operation.
The materials handling manager of a manufacturing company is trying to forecast the cost of maintenance for the company's fleet of over-the-road tractors. The manager believes that the cost of maintaining the tractors increases with their age. The following data was collected: Yearly Maintenance Yearly Maintenance Age (years) Age (years) Cost ($) Cost (S) 6.5 819 8.0 1,394 5.5 1,249 2.5 363 6.5 1,233 2.5 382 7.0 695 9.0 964 6.0 923 8.0 1,573 6.0 881 3.0 1,178 7.0 1,090 3.0 666 7.0 1,722 3.0 749 7.5 1,187 a. Use POM for Windows' least squares-linear regression module to develop a relationship to forecast the yearly maintenance cost based on the age of a tractor. (Enter your responses rounded to three decimal places and include a minus sign if necessary.) Y = 365.727 + 110,721 X where Y = Yearly maintenance cost in dollars and X= Age in years. b. If a section has 20 four-year-old tractors, what is the forecast for the annual maintenance cost? $ |- (Enter your response rounded to two…

A student group on a college campus wanted to create a survey about parking availability on campus. The student group randomly selected 300 students to take the survey. One of the questions read, “Many students believe the lack of available parking is a major problem. Do you agree or disagree?” Of the 300 students that took the survey, 285 surveys were returned. This survey will most likely suffer from which of the following types of bias? There is no bias in the way this survey is carried out. Response bias Selection bias Non-response bias
