The scope of this paper is to define a methodology for building robust PoD curves from numerical modelling. First, an experimental database will be created in a laboratory scenario. A representative sample of inspectors with different certification levels in NDT method will be employed. Multiple inspections will be carried out to include the human influence in the MAPOD calculation. In addition, this study will take into account the impact of using different devices in the High Frequency Eddy Current method (HFEC). Then, a simulation model is created taking into consideration the main uncertainties due to human and device factors. These uncertainties are identified and quantified by the observation of experimental NDT inspection. Then, statistical distributions of these uncertainties are derived and used as inputs of the simulation model. Finally, the simulation PoD model will be compared and validated with the experimental results developed in the laboratory scenario. This comparison provided encouraging results to replace or complete experimental tests by simulation.

本文的范围是定义一种从数值建模中构建健壮PoD曲线的方法。首先，将在实验室场景中创建实验数据库。将采用无损检测方法中具有不同认证级别的代表性检查员样本。将进行多次检查，以将人的影响纳入MAPOD计算中。此外，本研究还将考虑在高频涡流法（HFEC）中使用不同设备的影响。然后，考虑到人为因素和设备因素的主要不确定因素，创建了一个仿真模型。这些不确定性是通过观察NDT实验检查来确定和量化的。然后，得出这些不确定性的统计分布，并将其用作仿真模型的输入。最后，仿真PoD模型将与实验室场景中开发的实验结果进行比较和验证。这种比较提供了令人鼓舞的结果，可以通过仿真代替或完成实验测试。
