# Properties of systems

# Properties of Systems

**Properties of systems** — a set of characteristics that reflect the structure, functioning, behavior, and interaction of systems with their environment. These properties are studied within the frameworks of General Systems Theory and [systems analysis](https://systems-analysis.info/eng/Systems_analysis "Systems analysis"), covering a wide range of disciplines—from engineering and biology to cybernetics and management.

## General Characteristics

A [System](https://systems-analysis.info/eng/System "System") is viewed as an ordered set of interconnected [elements](https://systems-analysis.info/eng/System_element "System element") that interact with each other and with the external environment. The properties of systems allow for the description of their universal features, regardless of the subject area.

## Classification of Properties

### Structural and Holistic Properties

- **Wholeness** — the properties of a system cannot be reduced to the properties of its individual components; significant characteristics emerge only at the level of the system as a whole.
- **[Hierarchy](https://systems-analysis.info/eng/Hierarchy "Hierarchy")** — the organization of elements into levels with subordination and control.
- **Modularity** — the ability to identify autonomous components (subsystems) that interact with each other.
- **Decomposability** — the ability to decompose a system without losing its semantic integrity.
- **Isolation** — the ability of a system to function autonomously under certain conditions.

### Functional Properties

- **Purpose** — the goal-orientation of the system.
- **Functional completeness** — the presence of all necessary functions and components.
- **Optimality** — the ability to achieve goals with minimal resource expenditure.
- **Redundancy** — the presence of backup components or connections to increase reliability.

### Information and Control Properties

- **Identifiability** — the presence of unique attributes that allow the system to be distinguished from others.
- **Feedback** — the presence of correction mechanisms based on information about the current state.
- **Controllability** — the possibility of purposefully influencing the system from the outside.

### Dynamic Properties

- **[Stability](https://systems-analysis.info/eng/System_stability "System stability")** — the ability to maintain functionality under external and internal disturbances.
- **Reliability** — the ability to function without failures for a specified period.
- **Inertia** — a delay in the system's response to external influences.
- **[Adaptability](https://systems-analysis.info/eng/System_adaptability "System adaptability")** — the ability to change structure and behavior in response to changing conditions.

### Emergent and Behavioral Properties

- **[Emergence](https://systems-analysis.info/eng/Emergence "Emergence")** — the appearance of new properties in a system that are not characteristic of its individual components.
- **Synergy** — an effect that arises from the interaction of components, exceeding the sum of their individual effects.
- **[Equifinality](https://systems-analysis.info/eng/Equifinality "Equifinality")** — achieving the same final states from different initial conditions and paths.
- **Robustness** — the ability to maintain partial or full functionality when individual components fail.

### Properties under Uncertainty

- **Uncertainty** — the presence of factors that cannot be fully described or predicted.
- **Guaranteed result methods** — approaches that ensure stable functioning under conditions of uncertainty, without relying on probabilistic models.

## Properties and the System Lifecycle

Different properties become relevant at various stages of a system's lifecycle—from design to decommissioning:

- Design: modularity, controllability, optimality
- Operation: stability, reliability, feedback
- Modernization: adaptability, decomposability, equifinality
- Decommissioning: decomposability, isolation
