ModGen: a model generator for instrumentation analysis

Abstract A computer software tool for the automatic generation of steady-state process models to be used in instrumentation analysis was developed. We describe the program, called ModGen, discussing its main advantages and potential benefits. ModGen constitutes the front-end of a complete decision support system (DSS) for plant instrumentation design and revamp. This DSS is currently under development. The paper concludes with the description of ModGen's application to the classification of unmeasured variables of an existing medium-size process plant by means of GS-FLCN's structural technique for observability analysis.
