Progress in Evaluating the Reliability of NDE Systems - Paradigm Shift
- The paper will give an overview of new methodology for evaluating the reliability of NDE systems accurately, reliably and efficiently in accordance with the specific requirements of industrial application. After a review of the substantive issues from the status in 2002, the go forward guidance from these interactions is considered. At the beginning of the reliability analysis, the actual safety demands have to be defined in order to fit the investigation to the level of risk when the component would fail. Next, all the essential influencing parameters need to be documented and transferred to an appropriate design of experiments (DOE) to determine the reliability in terms of a qualitative assessment for lower risk or in terms of a quantitative probability of detection (POD) or ROC (Receiver Operating Characteristics) curves for higher safety demands. A new paradigm is offered to consider the POD or reliability of the system as a function of the configuration of input variables and useThe paper will give an overview of new methodology for evaluating the reliability of NDE systems accurately, reliably and efficiently in accordance with the specific requirements of industrial application.

A new paradigm is offered to consider the POD or reliability of the system as a function of the configuration of input variables and use it for optimisation rather than for a final judgement. An advantage for the end user is also to sample all single PODs to an integral Volume POD of a part. Among the influencing parameters, the human factor is the most important one. A systematic psychological approach shall help to find out where the bottlenecks are but most importantly to provide best possible working conditions for the human inspectors.…
