SDI
Rate and rank multiple user-defined design options against multiple user-defined criteria using a quantitative approach. SDI's approach to design trade-off is to evaluate how well the Design Option meets each Design Criterion by performing detailed, quantitative comparisons. The Total Score for each Design Option is calculated as the weighted sum of each Design Option Score per Design Criterion.
Design Option Scores are calculated for each Design Criterion using one of the following methods:
- Linear In-Spec: Linear variation inside the specification
- Quadratic In-Spec: Quadratic variation inside the specification
- In/Out Spec: Inside/Outside of specification
- Maximize
- Minimize
- 1-PNC: 1 - Probability of Non-Compliance (probability of compliance)
The Design Option with the highest score is the chosen as the "best" Option that comes closest to satisfying all the Design Criteria. In many cases, Design Criteria are conflicting, so there may be cases where the "best" Design Option exceeds the bounds of one or more the Design Criteria.
