What are the features of the system?

System characteristics refer to the properties common to general systems, mainly including: 1. Aggregation, the system is composed of at least two or more elements that can be distinguished from each other; 2. Correlation; 3. Purpose, that is, a certain specific function displayed by the system; 4. Hierarchy; 5. Environmental adaptability; 6. Dynamicity.

# System characteristics refer to properties common to general systems.

The characteristics of the system mainly include:

(1) Aggregation. A system is composed of at least two or more elements (or subsystems) that can be distinguished from each other. A single element cannot constitute a system, and identical elements cannot constitute a system even if they are large in number.

(2) Relevance. Each element (subsystem) in the system is interdependent, restricts and interacts with each other to form an interrelated whole. This specific "relationship" between elements (subsystems) reflects the integrity of the system. The elements are the same but they interact with each other to form an interrelated whole. Different correlation relationships lead to different overall characteristics of the system performance. It is this "relationship" that makes the existence of each element in the system dependent on the existence of other elements. Often when one element changes, other elements will also change accordingly, causing system changes.

(3) Purpose. Both artificial and composite systems have a clear purpose, that is, a specific function that the system performs. This purpose must be the overall purpose of the system, not the partial purpose of the system elements or subsystems. Often, a system may have multiple purposes.

(4) Hierarchy. A complex system consists of many subsystems, which may be divided into many subsystems, and the system itself is a component of a larger system. The system is hierarchical. For example, a living body has several levels: cells, tissues, organs, systems, and organisms; an enterprise has several levels: individuals, teams, workshops, and factories. The structure and function of the system refer to the structure and function at the corresponding level, but cannot represent the structure and function at the high level and low level. Generally speaking, the more layers there are, the more complex the system is.

(5) Environmental adaptability. The system has the ability to self-adjust as the external environment changes to adapt to the new environment. The system and the environment must carry out various forms of exchanges and are subject to environmental constraints and restrictions. Changes in the environment will directly affect the functions and purposes of the system. The system must make corresponding adjustments to its own functions when the environment changes, so as not to affect the purpose of the system. accomplish. A system without environmental adaptability has no vitality.

(6) Dynamic. First of all, the activities of the system are dynamic, and certain functions and purposes of the system are achieved through the exchange of material, energy, and information with the environment. Therefore, the organized movement of matter, energy, and information constitutes a dynamic cycle of system activity. Secondly, the system process is also dynamic. The system itself reflected in the life cycle of the system is also in the changing process of gestation, generation, development, decline and elimination.
