Use of Model Verification and Validation in Product Reliability and Confidence Assessments
This SAE standard outlines the steps and known accepted methodologies and standards for linking Model V&V with model based product reliability assessments. The standard’s main emphasis is that quantified values for Model-based product reliability must be accompanied by a quantified confidence value if the users of the model wish to claim use of a “Verified and Validated” model, and if they wish to further link into business and investment decisions that are informed by quantitative second-order risk and benefit cost considerations.
Rationale: SAE has numerous standards relating to the use of models65-67,70,71, and product reliability60-69. Other professional organizations (AIAA1, ASME5,6, DoD50, NASA58, etc) have recent standards for Model Verification & Validation (V&V). Lacking, however, is a standard relating the increasing use of numerical and computer Model V&V to quantitative design assessments of product reliability. It is the intent of SAE J2940 to provide such a standard.
