- During the various stages of the 1 point product life cycle, the attitudes and needs of target customers do not change. O True Falsearrow_forwardWhat is the reliability of the following parallel productionprocess? R 1 = 0.95, R2 = 0.90, R3 = 0.98.arrow_forwardHomework Rejection # = 6 Producers risk = 10% 2,000 hour life N=20 Failures =150, 265, 288, 301,325,365 Do you accept this lot????arrow_forward
- Explain how is the Bath-Tub curve obtained within the product life cycle?. How is it used in a reliability study? Explain how you would conduct a risk analysis evaluation in a reliability study?arrow_forwardFlextronchip, 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 $28. 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 2 0.1997 6 0.1998 14 0.1999 9 0.2000 45 0.2001 9 0.2002 8 0.2003 5 0.2004 2 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.arrow_forwardWhat is the purpose of Failure Mode, Effects and Criticality Analysis(FMECA)?
