layersindividual
Layersindividual is a term used to describe a modeling and design approach in which a system is decomposed into a set of layers, with each layer containing one or more discrete units called individuals. In this framework, a layer represents a level of abstraction or concern (for example, presentation, logic, data, or physical infrastructure), while each individual within a layer encapsulates state, behavior, and interfaces relevant to that level. The combination of layered structure and individual units supports modularity, traceability, and multi-scale analysis.
The term is not standardized across communities, but appears in discussions of modular design, agent-based modeling,
Core properties include independence of individuals from other layers, composability of layers, clearly defined interfaces, interoperability
Applications span software architecture, simulation and modeling, manufacturing digital twins, geographic information systems, and data visualization.
