Assume that the system still costs $600 to fix every time it breaks down, and you are going to run the system 1000 times. You are considering improving your system. You have contacted a backup supplier of component 1. She tells you that the backup for component 1 will cost $50,000. What would the minimum reliability of the backup need to be to make the purchase worthwhile? (keep 4 decimals for intermediate calculations)
Flextronchip, an OEM manufacturer, has a fifth-generation chip for cell phones, with chip specification of 0.2 ± 0.0002 mm for the distance between two adjacent pins. The loss due to a defective chip has been estimated as $20. Required: 1. Compute the value of k, the cost coefficient in the Taguchi quality loss function (QLF), L(x) = K(x- T)2. 2. Assume that the quality control manager takes a sample of 100 chips from the production process. The results are as follows: Measurement Frequency 0.1996 4 0.1997 7 0.1998 12 0.1999 11 0.2000 40 0.2001 10 0.2002 8 0.2003 5 0.2004 3 a. & b. Use the appropriate Taguchi quality loss function, L(x), to calculate the estimated quality loss for each of the observed measurements. Additionally, calculate the expected (i.e., average) loss per unit for the production process as a whole. Complete this question by entering your answers in the tabs below. Required 1 Required 2 Compute the value of k, the cost coefficient in the Taguchi quality loss…
Rick Wing, salesperson for Wave Soldering Systems, Inc. (WSSI), has provided you with a proposal for improving the temperature control on your present machine. The machine uses a hot-air knife to cleanly remove excess solder from printed circuit boards; this is a great concept, but the hot-air temperature control lacks reliability. According to Wing, engineers at WSSI have improved the reliability of the critical temperature controls. The new system still has the four sensitive integrated circuits controlling the temperature, but the new machine has a backup for each. The four integrated circuits have reliabilities of 0.82, 0.84, 0.86, and 0.88. The four backup circuits all have a reliability of 0.82. a) The overall reliability of the new temperature controller =% (enter your response as a percentage rounded to two decimal places). 1. If you pay a premium, Wing says he can improve all four of the backup units to 0.91. the overall reliability of the new temperature controller with the…
A jet engine has 10 components in series. Th e average reliabilityof each component is 0.998. What is the reliability of the engine?
An engine system consists of 2 main components in a series, all having the same reliability. Determine the level of reliability required for each of the components if the engine is to have a reliability of 0.989. round answer to 4 decimal places.
You have conducted a zone of tolerance analysis for your local pizzarestaurant. You find that the lengths of the reliability andresponsiveness boxes are much greater than those of the other threeservice quality dimensions. You also find that the restaurant ispositioned above the zone box on reliability but below the box onresponsiveness. What should you tell the manager to do?
A chain is composed of identical links with reliability of 0.9. How many links must a chain have in order for its reliability to be less than 0.5? Hint: Reliability of a series system is Rs=R1*R2….*Rn, which equals 0.9 multiplied by itself n times to get less than 0.5. Hence, Rs-0.5=0.9. By applying Ln to both sides, ln(0.5)=n*Ln(0.9). Now solve for n to get the answer.
Assume Bristol-Myers Squibb is faced with one source of business risk as worker's injury. The probability of worker injury is 0.09 and when the accident (injury) happens, the losses from a worker's injury has medical expenses of $8,000 and lost pay expenses of $90,000. What is the expected loss per worker? A-- $8,820 B-- $7,056 C-- none of the answers is correct D-- $7,417 E-- $17,640
A safety-critical system is one whose failure or misuse may cause human injury or death.Given that an EHR system can be considered to be such a system, which set of tasks associated with software implementation deserve special attention by the Midwest Hospital project team? a. Train end users, perform user acceptance testing, and provide for ongoing end-user support and training. b. Conduct an alpha and beta test, perform a direct conversion to start up the new system, and apply the Lewin and Schein three-stage model for implementing the new system to ensure that appropriate changes are made to people, structure, and tasks affected by the new system. c. Allow sufficient time for site preparation, perform a direct conversion from the old system to the new system, and employ the technology acceptance model to lead to better attitudes about the use of the new system. d. Perform thorough unit testing, conduct frequent system reviews to…
What is measurement reliability? How do we assess it (give one method) and what can we do to improve reliability?
Consider a product with three components in series, with reliabilities of 0.98, 0.76, and 0.89 for components A, B, and C, respectively. Furthermore, component B uses a backup that also has a reliability of 0.76. What is the reliability of the system? (Round answer to five decimal places.)
