For example three, now consider:
--- "system of (X)"
--- "part of (X)"
Where X can be , laws, games, airplanes, cars, plants.. and so on..
The "system concept" may be viewed as a real world relationship that is used to order or constrain the environment.
Using this basic view, two types of definitions for a system can be constructed as well as two main types of activity for system concepts.
The two definition types are, function (rule) and constructive (rule).
The two main activity types are discovery and design.
The functional rule definition for a system was given previously and is restated here, "A system is a constraint on variety, where the constraint identifies and defines the system of interest."
The construction rule definition for a system is, " A system is a non-empty set of objects and a non-empty set of relationships mapped over these objects and their attributes."
Humans tend to use the concept of a system for two main activities:
--- Discovering, documenting and discussing natural systems (systems not constructed by man).
--- Designing, documenting and discussing artificial systems (systems constructed by man).
Johannes Kepler's laws of planetary motion that describe the behavior of solar system under the defining constraints of natural physical forces is one example of using the system concept in the discovery mode.
The Wright brothers are an example of the application of the system concept used in the design mode.
These modes of application have different approaches, methods and techniques.
Mixing these modes may generate a high degree of semantic conflict.
