Claudio De Capua, Carmine Landi, Gennaro C. Malafronte

Abstract

In this paper is presented an original approach to the definition of the metrological characteristics of the measurement systems used in process index monitoring. The model proposed allows the evaluation of the probability that the process under statistical control shows a different behaviour from that inferred by the measured data, relating to the input conditions. The proposed model is developed in general hypothesis on the statistic characteristics of the process index monitoring and a typical application cases is presented.
