A product engineer has developed the following equation for the cost of a system component: C = (10P)2, where C is the cost in dollars and P is the probability that the component will operate as expected. The system is composed of 3 identical components, all of which must operate for the system to operate. The engineer can spend $254 for the 3 components. What is the largest component probability that can be achieved? (Do not round your intermediate calculations. Round your final answer to 4 decimal places.) Probability 0.8466
The HP dvd1040i 20X Multiformat DVD Writer has an MTBF of 70,000 hours. (a) Assuming continuous operation, what is the probability that the DVD writer will last more than 100,000 hours? (b) Less than 50,000 hours? (c) At least 50,000 hours but not more than 80,000 hours? (Product specifications are from www.hp.com.)
The goal of ............... is to identify protection requirements that ensure that system failures do not cause injury or death or environmental damage Select one: a. Requirement analysis b. Safety specification c. Protecion analysis d. Portection analysis
Consider a product that is "settled in." Its MTBF distribution has been found to be normal with a mean of 10,000 hours and a standard deviation of 100 hours. Answer the following questions: (a) Calculate the probability of a breakdown before 8,000 hours? (b) Calculate the probability of a breakdown before 9,000 hours? (c) Would you prefer a policy of “preventive maintenance” or a policy of “breakdown maintenance” on this product? Explain your choice.
The Worthington Gear Company installed a bank of 10 robots about three years ago. The robots greatly in-creased the firm’s labor productivity, but recently attention has focused on maintenance. The firm does no pre-ventive maintenance on the robots because of the variability in the breakdown distribution. Each machine hasan exponential breakdown (or interarrival) distribution with an average time between failures of 200 hours. Eachmachine hour lost to downtime costs $30, which means that the firm has to react quickly to machine failure.The firm employs one maintenance person, who needs 10 hours on average to fix a robot. Actual maintenancetimes are exponentially distributed. The wage rate is $10 per hour for the maintenance person, who can be putto work productively elsewhere when not fixing robots. Determine the daily cost of labor and robot downtime.
