Principles and Practice of Computer-Assisted Draft Object Modelling

Modeling is mathematical representation of a process, device, or concept by means of a number of variables that are defined to represent the inputs, outputs, and internal states of the device or process, and a set of equations and inequalities describing the interaction of these variables. It is a way to visualize a physical phenomenon using mathematical equations to describe its behavior during a certain period of time. So a model is basically an equation The model consists of simple polynomial equations but most of the real-world model consist of something called differential equations, which describe the "rate" of change of a certain quantity in the model. A practical "learn by doing" approach fosters the development of the skills beyond pure mathematics needed to set up and manipulate mathematical models.
