A highly composable system provides components that can be selected and assembled in various combinations to satisfy specific user requirements.
Modeling is understood as the purposeful abstraction of reality, resulting in the formal specification of a conceptualization and underlying assumptions and constraints.
While modeling targets the conceptualization, simulation challenges mainly focus on implementation, in other words, modeling resides on the abstraction level, whereas simulation resides on the implementation level.
Following the ideas derived from the Levels of Conceptual Interoperability model (LCIM), Composability addresses the model challenges on higher levels, interoperability deals with simulation implementation issues, and integratability with network questions.
Composability ensures the consistent representation of truth in all participating simulation systems of the federation.
