Problem 3: (10 points) (Quality Yield) 4 points Bonus Examine the graphic below with 3 widget processes (A - milling, B-hardening, C- finishing). Assume you start out with 500 widgets. (x=500). Lets call first pass yield FPY. Recall the yield equation discussed in class. a) What is the equation for FPY at Process B stage alone assuming that it has rework rate of 45% (A, C are fine)? (5 points) b) Now assume both process B, and C are associated with rework as shown in image below of 45% and 20% respectively. What is the FPY for process B and what is the FPY for process C? (5 points) c) Bonus: Your guess of combined FPY if both Process B and C have rework rates as noted? (4 points) (Hint: Use your response to part b). PROCESS PROCESS INPUT PROCESS B OUTPUT A C FPY Widgets Process B: Widget Hardening Process B: Widget Finishing Rework: 45% Rework: 20%
