The D-statistic is widely used in Statistical process control to reliably detect the out of control status, but by itself it offers no assistance as fault identification tool. Some strategies, that work in the original or ...

This paper deals with the modeling and control of a boiler for the transport of heat. Control applied is based on the integration of two distinct forms of process control, Statistical Process Control through the control ...

We present the non-conventional design of no charts used for the surveillance of processes characterized by a very low fraction nonconforming, with a costly and/or time-consuming inspection procedure. which makes the ...
