Systems and methods for leveraging a preliminary plant model to create a detailed physical plant model are presented. The system stores instances of component primitives, and can utilize stored geometries of the component primitives to identify a plurality of physical components to form a physical plant model. The physical plant model can realize at least a portion of the component runs based on equations and mapping definitions that establish relationships among the geometries of the equipment and piping. The components of the physical plant model can be mapped to catalog items based on the geometries of the components. After translation, a bill of materials listing the physical plant model components can be produced.

A method of building a model for a physical plant in the presence of noise can include initializing the model of the physical plant, wherein the model is characterized by a parameter vector, estimating an output of the model, and computing a composite cost comprising a weighted average of an error between the estimated output from the model and an actual output of the physical plant, and a derivative of the error.
