Definition of System

A system is a set of interacting or interdependent components that act according to a set of rules to form a unified whole. A system, surrounded and influenced by its environment, is described by its boundaries, structure, and purpose and is expressed in its functioning.

Identifying System Parameters

The concept of system can be applied to a wide variety of entities; to identify a system, three types of parameters must be specified:

1. Components of a system

2. Relationships among the components (system structure)

3. Behavior or function of the components (system behavior)

Defining a system in terms of only one or two parameters leads to an incomplete understanding of the entire system.

Each element in a system is either a part or a subsystem. A part is an element performing a specialized task within the system, while a subsystem is a group of collaborating elements that form a relatively separate entity within a system.

Classification of Systems

Systems can be classified into several types, based on various characteristics. Some of the common classifications include:

Open vs. Closed Systems

- An open system has exchanges with the surrounding environment, such as energy and matter. It can adapt and change due to external influences.

- A closed system does not interact with its external environment. It operates self-sufficiently and is not affected by external changes.

Natural vs. Artificial Systems

- A natural system is a self-organized and self-sustaining system that occurs naturally in the environment, such as an ecosystem or the solar system.

- An artificial system is a human-made system with a purpose or task, such as a computer, or a production system.

Deterministic vs. Non-deterministic Systems

- In a deterministic system, the behavior of the system can be predicted because the relationships among its components are well-defined and the system's future states can be calculated.

- A non-deterministic system, also called a stochastic or random system, exhibits random behavior or contains elements of unpredictability.

Linear vs. Non-linear Systems

- A linear system has inputs and outputs that are directly proportional and can be represented using linear equations.

- A non-linear system exhibits non-proportional relationships between inputs and outputs, often leading to complex and unpredictable behaviors.

Examples of Systems

Systems are widely encountered in various fields and areas, such as:

- Biological systems: ecosystems, organisms, organs, cells, molecules

- Physical systems: solar system, planets, weather systems, electricity circuits

- Artificial systems: computers, networks, engineering systems, transportation systems

- Social systems: families, organizations, communities, governments, ecosystems

- Cognitive systems: intelligence, learning, memory, emotions, decision-making

In conclusion, a system is an interconnected set of elements or components that function together as a unified whole. Identification and analysis of system characteristics, including system structure and behavior, are crucial for understanding and optimizing the performance of systems in different contexts and domains.
