ISQS 3344 Fall 2010 HW 2 1. Suppose that the specifications for a part (in inches) are 6.00 ± 0.25, and that the Taguchi Loss Function is estimated to be L(x) = 8,500(x-T)2. Determine the estimated loss if the quality characteristic under study takes on a value of 6.50 inches. Is the loss greater at 6.50 as opposed to 6.25? p.199,200 L(x) \$ 2,100 yes k 8400 531.25 at .25 x-T 0.5 2. Given the diagram below, determine the system reliability if the individual component reliabilities are: A = (x), B = 0.93, C = 0.92, and D = 0.94. Chapter 17 A x B 0.93 C 0.92 D 0.94 RaRb 0.93 1-((1-I15)*(1-0.93) RcRd 1 1-((1-0.92)*(1-0.94) RabRcd 0.93 B23*b24 3. What is the reliability of this system? If you could add one process (must be one of the existing processes) to best improve reliabilty what would be the improved reliability?
