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.
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.
