Can we make a universal index and certification for product robustness? 28 DTU Mechanical Engineering Robust Design Day 2015 09 Oct. 2015

Requirements for a… Product Robustness Index (PRI) 1. Dimensionless. 2. Comparable for similar products. 3. Suitable to any type of quantifiable performance. 4. Represents product betterment to consumer. 5. Suitable for measurement and simulation. 29 DTU Mechanical Engineering Robust Design Day 2015 09 Oct. 2015

Product Robustness Index (PRI) … A high level glimpse of the proposal PRI = MEAN(WF 1●PRIF 1; WF 1●PRIF 2; WF 1●PRIF 3… WF 1●PRIFn) The PRI is the Mean value of the PRI of each of the functions, multiplied by the importance weighting factor of each function. PRIF 1 = Unit of Variation Range (V) V: 30 DTU Mechanical Engineering Robust Design Day 2015 09 Oct. 2015
