A plastic injection molding machine operates 334 days a year. It is the bottleneck workstation in a process that produces plastic housed wall clocks. Industrial engineers collected data on the probability of machine breakdowns, the costs of preventive maintenance, and the cost of a breakdown. Number of Molding Machine Breakdowns per Day Probability of a breakdown 0 0.32 1 0.27 2 0.22 3 0.13 4 0.06 The cost of preventive maintenance is high due to performing it between 1 and 4 a.m. each day by two machine experts. The preventive maintenance cost is $2,030 per day including replacement parts, cleaning, and software upgrades. The cost of a breakdown of $1,940 is also high because the downstream workstations can only work until all work-in-progress inventory is completed; then the entire process must stop. What are the economics of the situation? Do not round intermediate calculations. Round your answers to the nearest cent. The expected cost of a breakdown per day is $ The manufacturing firm saves $ per year by performing preventive maintenance daily on the injection molding machine.

28. An expensive piece of equipment is used in the masking operation for semi- conductor manufacture. A capacitor in the equipment fails randomly. The capacitor costs $7.50, but if it burns out while the machine is in use, the production process must be halted. Here the replacement cost is estimated to be $150. Based on past experience, the lifetime distribution of the capacitor is estimated to be Probability of Failure Number of Months of Service 1 .08 2 .12 3 .16 4 .26 5 .22 .16 How often should the capacitors be replaced in order to minimize the expected monthly cost of planned and unplanned replacement?

Please do not give solution in image format thanku Genjeteye, Inc. makes aircraft engines. The mean time to failure has been found to be 100,000 hours and is exponentially distributed. a) What is the failure rate, A, per hour? b) What is the cumulative probability of failure after 10,000 hours or fewer? Between 10,000 and 15,000 hours? c) If Genjeteye wishes to provide a warranty that no more than 5 percent of the units will fail, how many hours of operation without failure should the company guarantee?

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…
