A reference matrix contains valid measurements characterizing operation of a multivariate process ( 220 ). Modeling parameters of the reference matrix are derived ( 222-232 ). The final model parameters, balanced with respect to measuring and modeling uncertainties ( 232 ), are applied to model ( 204 ) a new set of measurements ( 200 ). If the new set has no faults ( 206 ) then all modeled values and modeling uncertainties ( 208 ) can be used to control the process ( 218 ). If the new set has only one fault ( 210 ) ten the modeled value and modeling uncertainty of the faulted measurement plus the measured values and measuring uncertainties of the unfaulted measurements ( 212 ) can be used to control the process ( 218 ) while repair procedures are implemented for the identified fault ( 216 ). If the new set has more than one fault ( 214 ) then the process ( 218 ) should be shut down, and repair procedures should be implemented ( 216 ) for all identified faults.
