Mathematics, Modelling & Simulation

Modelling is an important activity at NPL, helping us to design and better understand measurement systems.

Often, a mathematical model is used to characterise the relationship between a number of variables in the system. The complexity of the model function can range from a simple polynomial function to requiring the solution of a differential equation. Given both the model function and information about the inputs to the system, the response of the system may be predicted.

The capabilities within the group include: model development; curve and surface fitting, and feature extraction; signal processing; numerical approximation methods for solution of differential equations; uncertainty evaluation; and software and database development. We use a range of commercial and in-house packages and can develop tailor-made solutions for challenging problems.
