Ans. Examples
of modelling.

(i)
Mathematical modelling is a potential advantage to industries. Models are used to
quickly explore new solutions and innovations that can save time and money in
the development and validation phases. e.g. in a T.V. industry for innovative
designs, multiple testing and optimization for efficiency.

(ii) For
weather prediction, mathematical model of the atmospheric motions are based on
well known equations and phenomena. For a realistic and useful description, all
the subsystems have to be modelled to study their behaviour and interactions.
