Decision procedures of automated system for inspection program development

Fatigue failure probability of airframe depends on unknown distribution parameters of fatigue crack growth model. The parameters should be estimated by processing of airframe full-scale fatigue test results. A definition of p-set function as specific statistical decision function is introduced. The...

Description
Summary:Fatigue failure probability of airframe depends on unknown distribution parameters of fatigue crack growth model. The parameters should be estimated by processing of airframe full-scale fatigue test results. A definition of p-set function as specific statistical decision function is introduced. The use of the function, which defines some p-set for random vector, provides limitation of supremum of failure probability (as a function of unknown parameter) instead of dubious compromise combination of required reliability and confidence probability. The calculations are complex enough but it can be used in frame of automated system.
