What is System?
One of the most used words today is the word "system". System concept; Although it has a very broad meaning; It can be explained as continuous relationships between multiple entities. These beings can be biological, physical, human or intellectual. It would not be an exaggeration to say that we can come across the word system everywhere and at all times. We can see that the word system is used in daily speeches and distinguished meetings. In our daily life, transportation systems, education system, banking systems, solar system and even football team systems are all structures that are included in our daily life. Many more concepts like these come right next to the word system. In a sense, everything around us is a system: a tree, an apartment, a person, a city, a car, etc.
It is quite difficult to fit a word with such broad meanings into a single definition. However, despite such widespread and different usage, it can be said that all these concepts we call systems carry some common and universal points.
System Approach
The system approach is accepted as a framework in which we can examine the events, situations and problems as a whole, it expresses the approach from the perspective of system view and system thought. System; It can be defined as a coherent whole with a boundary that separates internal and external factors, interacting with the environment to determine inputs and outputs associated with the system. System Features The system is a whole. Systems are interrelated, systems represent more than the sum of the subsystems that compose them. Every system has a perimeter. Sub-systems are parts of the system that affect each other and have a complex structure between them. Sub-systems can be added and removed to systems. The structure of the system constantly changes cyclically in accordance with its environment and its own characteristics. The system creates outputs with the inputs it receives. Since the systems are interrelated, it is impossible to determine the boundaries of the systems precisely.
System Types
Open and Closed Systems: An open system becomes an open system when matter receives energy or information inputs and outputs from this information, and open systems depend on the environment. A closed system is a system that is open only for information input and is independent from the environment in all its other activities.
Living and Non-Living Systems: Systems with biological properties are living systems. Live systems are open systems to the environment. All living systems are biological systems and biological systems die at the end of their life. Systems that do not show vitality properties are called inanimate systems.
Real Systems (Concrete or Physical): These are systems whose results are derived from observations and are found independent of the observer.
Abstract Systems: They are conceptual systems that fit reality. Modeling can be given as an example.
Conceptual System: Systems with symbolic thought structures such as linguistics, mathematics and logic.
Social Systems: Systems formed by human groups. People need to form groups in line with their common values, languages and belief systems and material and moral interests in order to unite in common points. Every person, as he is a system, enters social systems and becomes a part of it, that is, its sub-system.
