A functional regression control chart for profile monitoring

In many applications, profile monitoring techniques are needed when the quality characteristic under control can be modeled as a function. Moreover, measures of other functional covariates are often available together with the functional quality characteristic. To combine the information coming from all the measures attainable, a new functional control chart is proposed for profile monitoring. It relies on the residuals of a function-on-function linear regression of the quality characteristic on the functional covariates. The effectiveness of the proposed monitoring scheme is illustrated on a real-case study about the monitoring of CO2 emissions from a Ro-Pax ship owned by the shipping company Grimaldi Group.
