7. R Balisnomo 7 Objectives: How hard should the face plate be for maximum strength? What is certainty that the deadbolt will tolerate 4,150 ft-lbs of force? Strength Frame machine was used for measuring the pull strength. 3/3/2010
29. R Balisnomo 26 Answers: How hard should the face plate be for maximum strength? 42.0 Rockwell C for an expected pull strength of 4,200 ft-lbs. What is certainty that the deadbolt will tolerate 4,150 ft-lbs of force? 99.84% @ 42.0 Rockwell C Strength Frame machine was used for measuring the pull strength. 3/3/2010
30. R Balisnomo 27 ORACLE Crystal Ball is needed in new product development because: Errors are inherent in all predictive models (e.g., Linear Regression or Design of Experiments). We need a tool for modeling them (risks) so that our new products perform as expected. Often times we are searching for that “Sweet Spot” or Optimal Point that lets our product perform at its peak best. We want to know the probability of success (or failure) associated with our design or performance goals. 3/3/2010

56. R Balisnomo 53 ORACLE Crystal Ball® is needed in new product development because: When it comes to tolerance stack-ups1 there is no better tool for optimizing fit and function. Humans typically cannot simultaneously adjust +40 interdependent variables at the same time. It’s exponentially easier to fix the problem in the Design Phase then it is to fix the problem once the product has launched. It’s a good tool for translating quality and engineering terms into language finance and management can understand. 3/3/2010 1. note: Cartesian -- not GD&T

71. 63 R Balisnomo The model does not know that only one of the four suppliers can produce each part. We have to specify this constraint into the analysis. 3/3/2010
72. 64 R Balisnomo This constraint only allows one supplier out of four to produce each part. 3/3/2010
73. 65 R Balisnomo Due to time constraints, we may be running the optimization for a much-less time (only 3-5 minutes); thus, your actual results may vary from this presentation. 3/3/2010

82. R Balisnomo 74 ORACLE Crystal Ball® is needed in new product development because: The trade-offs between RISK and REWARD are difficult to quantify. Efficient Frontiers is a tool that specializes in the above. Simple YES/NO or GO/STOP decisions become complex in the face of so many combinations and permutations. Sometimes it’s better to let the a Computer make the long-term business decisions. We can make a lot of money by solving big and difficult problems in a short amount of time. 3/3/2010
