Chapter 4, Problem 8P
Examine the systems given below. Which system is more reliable, a or b? c or d? Now calculate the reliability of each system. Were your perceptions correct?
If it costs $1000 for each 90% reliable component, $1500 for each 93% component, $2000 for each 95% reliable component, and $10,000 to replace a failed system, which system would you choose, a or b? c or d?

CEO John Spychalski is concerned about a problem that has existed at CBN railroad for almost 20 years now. The continuous problem has been that the locomotives used by the company are not very reliable. Even with prior decisions to resolve the problem, there still has not been a change in the reliability of these locomotives. Between 2013 and 2014, 155 new locomotives were purchased and one of CBN's repair shops was reno- vated. The renovated shop has been very inefficient. Spychalski estimated that the shop would complete 300 overhauls on a yearly basis, but instead it has only managed to com- plete an average of 160 overhauls per year. The company has also been doing a poor job servicing customers (that is, providing equipment). CBN has averaged only 87 to 88 percent equipment availability, compared to other railroads with availability figures greater than 90 percent. Increased business in the rail industry has been a reason for trying to reduce the time used for repairing the…

Thank you for your assistance!arrow_forwardMachine A was purchased last year for $20,000 and had an estimated market value of $2,000 at the end of its 6-year useful life. Annual operating costs are $2,000. The machine will perform satisfactorily over the next 5 years. A salesperson for another company is offering a replacement, machine B , for $14,000 with a market value of $1,400 after 5 years. Annual operating costs for machine B will only be $1,400. A trade-in allowance of $10,400 has been offered for machine A. If the MARR is 12% per year, should you buy the new machine? Use RORAI method.
