1. Abstract System and Physical System

  • An abstract system is conceptual, a product of a human mind. That is, it cannot be seen or pointed to as an existing entity. Social, theological, cultural systems are abstract systems. None of them can be photographed, drawn or otherwise physically pictured. However, they do exist and can be discussed, studied and analyzed.
  • A physical system, in contrast, has a material nature. It is based on material basis
    rather than on ideas or theoretical notions. Computer system is one of example for physical system.

2. Natural System and Unnatural System

  • Natural system is system that made naturally without human intervention. For example, a lake, a mountain, and so on.
  • Unnatural system is system that made with human intervention. For example, a plane, a factory, a car, a ship and so on.

3. Deterministic System and Probabilistic System

  • Deterministic system is limit scope system that has a fix purpose. This system operates with certain ways. Interaction between the parts are known. For example, computer programs.
  • Probabilistic System is probability things, always have a little error when the system is running. For example, stock product.

4. Simple System and Complex System

  • Simple system is system that include small number of elements, few interactions, attributes are predetermined, interaction are highly organized, well defined laws govern behavior, system does not evolved over time, sub-systems does not pursue their own goals, unaffected by behavioral influence, and largely closed to environment.
  • A complex system is a system composed of interconnected parts that as a whole exhibit one or more properties (behavior among the possible properties) not obvious from the properties of the individual parts. A system’s complexity may be of one of two forms: disorganized complexity and organized complexity.[1] In essence, disorganized complexity is a matter of a very large number of parts, and organized complexity is a matter of the subject system (quite possibly with only a limited number of parts) exhibiting emergent properties. Examples of complex systems include ant colonies, human economies, climate, nervous systems, cells and living things, including human beings, as well as modern energy or telecommunication infrastructures. Indeed, many systems of interest to humans are complex systems. Complex systems are studied by many areas of natural science, mathematics, and social science. Fields that specialize in the interdisciplinary study of complex systems include systems theory, complexity theory, systems ecology, and cybernetics[]

5. Closed System and Open System

  • Closed sytem self contained system. This system is not depend on outer environment. For example, chemestry reaction on the tube.
  • Open system is a system that depend on outer environment. Adaptability system for the environment changing. This system can keep its exist.  For example, business organization.
