Despite the field diversity, all ''structural analog'' analysis use some level of abstraction to transform

models A model is an informative representation of an object, person or system. The term originally denoted the plans of a building in late 16th-century English, and derived via French and Italian ultimately from Latin ''modulus'', a measure. Models c ...

algorithms In mathematics and computer science, an algorithm () is a finite sequence of rigorous instructions, typically used to solve a class of specific problems or to perform a computation. Algorithms are used as specifications for performing ...

. Example: for molecular structure comparison and classification operations, the compared compounds are modeled as a mathematical graph.

Analogical models Analogical models are a method of representing a phenomenon of the world, often called the "target system" by another, more understandable or analysable system. They are also called dynamical analogies. Two open systems have ''analog'' represe ...

are used in a method of representing a ‘ target system’ by another, more understandable or analysable system. Two systems have analog structures (see illustration) if they are isomorphic graphs and have equivalent (mapped)

lumped elements The lumped-element model (also called lumped-parameter model, or lumped-component model) simplifies the description of the behaviour of spatially distributed physical systems, such as electrical circuits, into a topology consisting of discrete e ...
