- system analysis
Concepts covered in this chapter include:
Scientific theories deal with concepts, not with reality.
Systems theory uses mathematical concepts to describe aspects of the ‘real-world’.
A formal model is a graph, i.e. a subset of a product space formed by variables characterizing a system or process.
An observable is some characteristic of a system which can, in principle, be measured.
A state is a specification of a system or process at a specific instant.
A dynamic system or process is a system in which the state changes with time.
Differential equations are a common way to encode dynamics.
There are many alternative and equally valid ways to represent a system...
