Abstract

A software plant process modeling system operates in multiple modes. The software system uses process unit models. A process unit model includes at least one equation and at least one variable. The software system sets a status of a variable in the unit model to a first state. The first state is associated with a first mode of operation. The software system then sets the status of the same variable in the unit model to a second state. The second state is associated with a second mode of operation. The software system generates an open-equation model in operating in multiple modes. The software system receives a modification to at least one process unit model. Thus, a user may create a single plant process model for operation in multiple modes.
