Abstract:
1. A computer readable medium encoded with a computer program for creating a combined function simulation model that represents a combined system and corresponds to a combined mathematical model, using a plurality of component function simulation models that each represent a component of the combined system and corresponds to a component mathematical model being identified by a first state variable that represents a moving amount or a quantity of a medium that carries energy and a second state variable that represents a strength or an amount of energy of a medium, wherein each of the component function simulation models include linear characteristic elements that have a regular relationship between input and output values, and at least one of the component function simulation models includes a nonlinear characteristic element that has an irregular relationship between input and output values or outputs irregular data independently, the program being executed by a computer to perform: separating the nonlinear characteristic element and the linear characteristic elements, and replacing the nonlinear characteristic element with a predetermined linear element corresponding to a linear mathematical element; combining the plurality of component function simulation models using the corresponding component mathematical models to create a combined linear function simulation model represented as a combined linear mathematical model; and reinserting the nonlinear characteristic element in place of the predetermined linear element corresponding to the linear mathematical element to create the combined function simulation model represented as a combined mathematical model including at least a nonlinear characteristic element.
