General Systems Theory

General Systems Theory

1. History

   • In 1955, the general theory is developed by Roos Asbhy
     • • Ross Ashby (London, 6 September 1903 – 15 November 1972) was an English psychiatrist and a pioneer in cybernetics, the study of complex systems. His first name was not used: he was known as Ross Ashby. His two books, Design for a Brain and An Introduction to Cybernetics, were landmark works. They introduced exact and logical thinking into the nascent discipline and were highly influential.
   • The general theory of systems idea developed by Karl Ludwig von Bertalanffy in 1930, was a theme new that caused great impact in the scientific community.
     • • (September 19, 1901 – June 12, 1972) was an Austrian biologist known as one of the founders of general systems theory (GST). This is an interdisciplinary practice that describes systems with interacting components, applicable to biology, cybernetics, and other fields. Bertalanffy proposed that the classical laws of thermodynamics applied to closed systems, but not necessarily to "open systems," such as living things. His mathematical model of an organism's growth over time, published in 1934, is still in use today. Bertalanffy grew up in Austria and subsequently worked in Vienna, London, Canada, and the USA

2. Systems theory or systems science is the interdisciplinary study of systems in general, with the goal of discovering patterns and elucidating principles that can be discerned from and applied to all types of systems at all nesting levels in all fields of research. It can reasonably be considered a specialization of systems thinking or as the goal output of systems science and systems engineering, with an emphasis on generality useful across a broad range of systems (versus the particular models of individual fields).

3. Examples of applications

   • • Systems biology • Systems engineering • Systems psychology

4. A model of set of interrelated principles and concepts that explains and organization complex entities.

5. GST Facts

   • Bertalanffy expressed that real systems are exposed to, and work together with, their enviromentes and can obtain qualitatively new properties through development resulting in constant development
   • Concepts
     • Input - Output - Process - State - Hierarchy - Goal Directedness - Information - System environment boundary

6. How is GST relevant to Us?

7. Information System

   • System consisting of the networks of all comunication channels used within an organization

8. Network Security System

   • The objective of network security includes protection of information and property from theft, corruption, or natural disaster, while allowing the information and property to remain accesible and productive to its intenden users
