Flussbasierte

Flussbasierte is a term used in German-language technical writing to describe systems, architectures, and methodologies that organize themselves around the movement and transformation of flows through a network of processing units. The core idea is that components are connected by streams of data, materials, or energy, and the system’s behavior emerges from the way these flows are directed, transformed, and synchronized rather than from centralized control.

In computer science, flow-based programming (FBP) is the best-known instantiation of this principle. In FBP, applications are assembled from independent components with well-defined input and output ports, connected by data streams. Components run concurrently and communicate by packets, enabling modularity, reusability, and visual representation as graphs. The German literature often uses “flussbasierte Programmierung” or “datenflussbasierte Programmierung” as translations or equivalents.

In engineering and operations research, flussbasierte modelling describes processes where the focus is on the movement of substances or information through a system—such as manufacturing lines, supply chains, or water networks—rather than on a single controlling entity. Models emphasize throughput, bottlenecks, and the routing of flows, and are used for simulation, optimization, and control design.

In hydrology and environmental sciences the term is sometimes used to refer to river-flow–driven models that simulate discharge, sediment transport, or pollutant fate based on flow regimes.

Advantages of flussbasierte approaches include modularity, natural parallelism, and clarity of data dependencies. Challenges include managing asynchronous communication, debugging distributed components, and ensuring correctness of flow connections as systems scale.
