# Classification of systems

# Classifications of Systems

**Classifications of systems** is the process of grouping [systems](https://systems-analysis.info/eng/System "System") based on characteristics that reflect their structure, functioning, and development. System classification simplifies their analysis and helps in selecting methods for modeling and management optimization.

## Essence of Classification

Classification is a fundamental method of scientific cognition aimed at organizing objects according to their essential characteristics. It serves the following functions:

- systematizing knowledge,
- facilitating problem formulation,
- selecting research methods.

A classification should adhere to the following principles:

- unity of basis,
- completeness of object coverage,
- hierarchical structure,
- practical applicability.

## Bases for System Classification

Different bases for classification are applied to systems depending on the goals of the analysis:

- **By origin**: natural and artificial.
- **By domain**: technical, biological, social, economic.
- **By materiality**: material and abstract systems.
- **By interaction with the [environment](https://systems-analysis.info/eng/System_environment "System environment")**: open and closed.
- **By the nature of functioning**: deterministic and stochastic.
- **By complexity**: simple and complex.
- **By development**: static and dynamic (evolving).

These classification criteria help in selecting appropriate methods for description, analysis, and optimization.

## Methodological Approaches to Classification

Methodological classifications take into account the goals and methods of research:

- **By discipline**: mathematics, physics, biology, etc.
- **By formalization**: formalizable and weakly-formalizable systems.
- **By the role of the observer**: the classification depends on the goals and stage of the research ([Observer in the systems approach](https://systems-analysis.info/eng/Observer_in_the_systems_approach "Observer in the systems approach")).

The classification of a system should align with the tasks of modeling, forecasting, or management.

## Scientific Approaches to Classification

Scientific classifications aim to identify universal principles of systems:

- **Hierarchy of systems**: from static structures to social systems (K. Boulding).
- **Nature of processes**: static, dynamic, self-organizing.
- **Degree of development**: evolving and stable systems.
- **Multi-aspect classifications**: a combination of characteristics for a more complete description.

These approaches provide a unified conceptual framework for interdisciplinary research.

## Philosophical Aspects of Classification

The philosophical level of classification reflects conceptions of the nature of systems:

- **Objectivist approach**: classification captures objective differences.
- **Constructivist approach**: classification is created for the purposes of analysis and modeling.
- **Dialectical approach**: classification reflects the unity of the objective and subjective in the cognition of systems.

Philosophical analysis emphasizes that classification is always linked to the researcher's goals.

## Comparative Overview of Approaches

- **L. von Bertalanffy**: open and closed systems, with an emphasis on interaction with the environment.
- **K. Boulding**: classification by levels of complexity.
- **A. Hall**: engineering systems analysis, structural classification.
- **Yu. I. Chernyak**: multiplicity of classifications depending on the goal of the analysis.
- **V. N. Volkova**: practical application of classifications for the analysis of social and organizational systems.

The evolution of these approaches shows a transition from rigid schemes to flexible, multi-aspect classifications.
