MEASUREMENT OF QUALITY INDEXES IN PROCESS MONITORING: AN ORIGINAL APPROACH TO UNCERTAINTY ANALYSIS

In this paper is presented an original ap- proach to the definition of the metrological characteristics of the measurement systems used in process index monitoring. The model proposed allows the evaluation of the prob- ability 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 de- veloped in general hypothesis on the statistic characteristics of the process index monitoring and a typical application cases is presented.
