Patent ID: 6973413

Claim:
An integrated system for ensuring the performance and health of a plurality of instruments and processes, said system comprising: a plurality of sensor signals each representing an output from a sensor; and a computer responsive to said plurality of sensor signals, said computer programmed to execute a process for verifying instrument and process health comprising: storing a plurality of sampled data in a storage media, said plurality of sampled data corresponding to said plurality of sensor signals; and analyzing said sampled data and producing analysis results, said step of analyzing including performing a static analysis and performing a dynamic response analysis, said computer programmed to execute a process for said static analysis including, under steady state conditions: for a process value with at least one redundant value, averaging a plurality of redundant channel process values to determine a measured process value, for said process value without said at least one redundant value, said measured process value being equal to said process value, determining a model process value from at least one of an empirical model and a physical model, averaging said measured process value and said at least one model process value to produce an estimated process value, if a reference channel process value is available, including said reference channel process value in averaging to produce said estimated process value, and determining a deviation for said process value from said estimated process value.
